Maternal exposure to atrazine during lactation suppresses suckling-induced prolactin release and results in prostatitis in the adult offspring. (1/193)

The availability of prolactin (PRL) to the neonatal brain is known to affect the development of the tuberoinfundibular (TIDA) neurons and, as a consequence, lead to alterations in subsequent PRL regulation. Without early lactational exposure to PRL (derived from the dam's milk), TIDA neuronal growth is impaired and elevated PRL levels are present in the prepubertal male. These observations, combined with the finding that alterations in PRL secretion (i.e., hyperprolactinemia) in the adult male rat have been implicated in the development of prostatitis, led us to hypothesize that early lactational exposure to agents that suppress suckling-induced PRL release would lead to a disruption in TIDA development, altered PRL regulation, and subsequent prostatitis in the male offspring. To test this hypothesis, suckling-induced PRL release was measured in Wistar dams treated twice daily with the herbicide atrazine (ATR, by gavage, on PND 1-4 at 0, 6.25, 12.5, 25, and 50 mg/kg body weight), or twice daily with the dopamine receptor agonist bromocriptine (BROM, sc, at 0.052, 0.104, 0.208, and 0.417 mg/kg); BROM is known to suppress PRL release. Similarly, atrazine has also been reported to suppress PRL in adult females. Serum PRL was measured on PND 3 using a serial sampling technique and indwelling cardiac catheters. A significant rise in serum PRL release was noted in all control females within 10 min of the initiation of suckling. Fifty-mg/kg ATR inhibited suckling-induced PRL release in all females, whereas 25 and 12.5 mg/kg ATR inhibited this measure in some dams and had no discernible effect in others. The 6.25 mg/kg dose of ATR was without effect. BROM, used here as a positive control, also inhibited suckling-induced PRL release at doses of 0.104 to 0.417 mg/kg, with no effect at 0.052 mg/kg. To examine the effect of postnatal ATR and BROM on the incidence and severity of inflammation (INF) of the lateral prostate of the offspring, adult males were examined at 90 and 120 days. While no effect was noted at 90 days of age, at 120 days, both the incidence and severity of prostate inflammation was increased in those offspring of ATR-treated dams (25 and 50 mg/kg). The 12.5 mg/kg ATR and the two highest doses of BROM increased the incidence, but not the severity, of prostatitis. Combined treatment of ovine prolactin (oPRL) and 25 or 50 mg/kg ATR on PND 1-4 reduced the incidence of inflammation observed at 120 days, indicating that this increase in INF, seen after ATR alone, resulted from the suppression of PRL in the dam. To determine whether or not there is a critical period for these effects, dams were dosed with 25 and 50 mg/kg on PND 6-9 and PND 11-14. Inflammation was increased in those offspring from dams treated on PND 6-9, but this increase was not significant. Dosing on PND 11-14 was without effect. These data demonstrate that ATR suppresses suckling-induced PRL release and that this suppression results in lateral prostate inflammation in the offspring. The critical period for this effect is PND 1-9.  (+info)

Associations between stomach cancer incidence and drinking water contamination with atrazine and nitrate in Ontario (Canada) agroecosystems, 1987-1991. (2/193)

BACKGROUND: Nitrate and atrazine are two chemicals that are heavily used in certain sectors of agriculture. They are suspected to be associated with the development of certain types of tumours. METHODS: Existing data were obtained on the incidence of specific types of cancers, contamination of drinking water with atrazine and nitrate, and related agricultural practices for the 40 ecodistricts in the province of Ontario. The data were merged into a georelational database for geographical and statistical analyses. Weighted (by population size) least squares regression analyses were conducted while controlling for confounding socioeconomic and lifestyle factors. Maximum likelihood spatial error models were estimated when least square regression error terms were found to be spatially autocorrelated using the Moran's I statistic. RESULTS: Atrazine contamination levels (range 50-649 ng/l, maximum acceptable concentration [MAC] = 60000 ng/l) were positively associated (P < 0.05) with stomach cancer incidence and negatively associated with colon cancer incidence. Nitrate levels, (range 0-91 mg/l, MAC = 10 mg/l) were negatively associated with stomach cancer incidence. CONCLUSION: The associations found at the ecodistrict level, both positive and negative, if confirmed by other studies, raise serious questions about maximum allowable limits for atrazine, as well as possibilities of complex trade-offs among disease outcomes, and interactions of biophysical and social mechanisms which might explain them. Although the negative associations appear to have no direct biological explanations, such counter-intuitive outcomes may occur in complex systems where social and biological variables interact.  (+info)

Atrazine disrupts the hypothalamic control of pituitary-ovarian function. (3/193)

The chloro-S-triazine herbicides (i.e., atrazine, simazine, cyanazine) constitute the largest group of herbicides sold in the United States. Despite their extensive usage, relatively little is known about the possible human-health effects and mechanism(s) of action of these compounds. Previous studies in our laboratory have shown that the chlorotriazines disrupt the hormonal control of ovarian cycles. Results from these studies led us to hypothesize that these herbicides disrupt endocrine function primarily through their action on the central nervous system. To evaluate this hypothesis, we examined the estrogen-induced surges of luteinizing hormone (LH) and prolactin in ovariectomized Sprague-Dawley (SD) and Long-Evans hooded (LE) rats treated with atrazine (50-300 mg/kg/day, by gavage) for 1, 3, or 21 days. One dose of atrazine (300 mg/kg) suppressed the LH and prolactin surge in ovariectomized LE, but not SD female rats. Atrazine (300 mg/kg) administered to intact LE females on the day of vaginal proestrus was without effect on ovulation but did induce a pseudopregnancy in 7 of 9 females. Three daily doses of atrazine suppressed the estrogen-induced LH and prolactin surges in ovariectomized LE females in a dose-dependent manner, but this same treatment was without effect on serum LH and prolactin in SD females. The estrogen-induced surges of both pituitary hormones were suppressed by atrazine (75-300 mg/kg/day) in a dose-dependent manner in females of both strains evaluated after 21 days of treatment. Three experiments were then performed to determine whether the brain, pituitary, or both organs were the target sites for the chlorotriazines. These included examination of the ability of (1) the pituitary lactotrophs to secrete prolactin, using hypophyosectomized females bearing pituitary autotransplants (ectopic pituitaries); (2) the synthetic gonadotropin-releasing hormone (GnRH) to induce LH secretion in females treated with high concentrations of atrazine for 3 days; and (3) atrazine (administered in vivo or in vitro) to suppress LH and prolactin secretion from pituitaries, using a flow-through perifusion procedure. In conclusion, the results of these studies demonstrate that atrazine alters LH and prolactin serum levels in the LE and SD female rats by altering the hypothalamic control of these hormones. In this regard, the LE female appeared to be more sensitive to the hormone suppressive effects of atrazine, as indicated by the decreases observed on treatment-day 3. These experiments support the hypothesis that the effect of atrazine on LH and prolactin secretion is mediated via a hypothalamic site of action.  (+info)

Isotope-labeled immunoassays without radiation waste. (4/193)

The practice of immunoassay has experienced a widespread transition from radioisotopic labeling to nonisotopic labeling over the last two decades. Radioisotope labels have drawbacks that hamper their applications: (i) perceived radiation hazards of reagents, (ii) regulatory requirements and disposal problems of working with radioactive materials, and (iii) short shelf-life of the labeled reagents. The advantage of isotopic labeling is the incorporation into analytes without altering structure or reactivity, as is often the case with ELISA or fluorescent detection systems. We developed a format for isotope label immunoassay with the long-life isotope (14)C as the label and accelerator mass spectrometer (AMS) as the detection system. AMS quantifies attomole levels of several isotopes, including (14)C. With this exquisite sensitivity, the sensitivity of an immunoassay is limited by the K(d) of the antibody and not the detection system. The detection limit of the assays for atrazine and 2,3,7,8-tetrachlorodibenzo-p-dioxin was 2.0 x 10(-10) M and 2.0 x 10(-11) M, respectively, approximately an order of magnitude below the standard enzyme immunoassay. Notably, <1 dpm (0.45 pCi) of (14)C-labeled compound was used in each assay, which is well below the limit of disposal (50 nCi per g) as nonradioactive waste. Thus, endogenous reporter ligands quantified by AMS provide the advantages of an RIA without the associated problems of radioactive waste.  (+info)

Determination of selected herbicides and phenols in water and soils by solid-phase extraction and high-performance liquid chromatography. (5/193)

A high-performance liquid chromatography procedure or the determination of the herbicides simazine, propazine, bromacil, metoxuron, and hexazinone is elaborated. Stationary phases RP8 and RP18 and mixtures of methanol-water (2:1 and 1:1, v/v) as a mobile phase are applied for this purpose. The conditions for solid-phase extraction are established, allowing the separation of phenols and herbicides in their mixtures and the extraction of phenols (from river and coke plant water) and herbicides (from the soil samples).  (+info)

Analysis of the diversity of a sheep antibody repertoire as revealed from a bacteriophage display library. (6/193)

We have applied bacteriophage display technology to construct and analyze the diversity of an IgG library of >1 x 108 clones from an adult sheep immunized against the hapten atrazine. We have identified eight new VH gene families (VH2-VH9) and five new Vkappa gene families (VkappaV-VkappaIX). The heavy and kappa light chain variable region gene loci were found to be far more diverse than previously thought.  (+info)

Characterization of an atrazine-degrading Pseudaminobacter sp. isolated from Canadian and French agricultural soils. (7/193)

Atrazine, a herbicide widely used in corn production, is a frequently detected groundwater contaminant. Fourteen bacterial strains able to use this herbicide as a sole source of nitrogen were isolated from soils obtained from two farms in Canada and two farms in France. These strains were indistinguishable from each other based on repetitive extragenic palindromic PCR genomic fingerprinting performed with primers ERIC1R, ERIC2, and BOXA1R. Based on 16S rRNA sequence analysis of one representative isolate, strain C147, the isolates belong to the genus Pseudaminobacter in the family Rhizobiaceae. Strain C147 did not form nodules on the legumes alfalfa (Medicago sativa L.), birdsfoot trefoil (Lotus corniculatus L.), red clover (Trifolium pratense L.), chickpea (Cicer arietinum L.), and soybean (Glycine max L.). A number of chloro-substituted s-triazine herbicides were degraded, but methylthio-substituted s-triazine herbicides were not degraded. Based on metabolite identification data, the fact that oxygen was not required, and hybridization of genomic DNA to the atzABC genes, atrazine degradation occurred via a series of hydrolytic reactions initiated by dechlorination and followed by dealkylation. Most strains could mineralize [ring-U-(14)C]atrazine, and those that could not mineralize atrazine lacked atzB or atzBC. The atzABC genes, which were plasmid borne in every atrazine-degrading isolate examined, were unstable and were not always clustered together on the same plasmid. Loss of atzB was accompanied by loss of a copy of IS1071. Our results indicate that an atrazine-degrading Pseudaminobacter sp. with remarkably little diversity is widely distributed in agricultural soils and that genes of the atrazine degradation pathway carried by independent isolates of this organism are not clustered, can be independently lost, and may be associated with a catabolic transposon. We propose that the widespread distribution of the atrazine-degrading Pseudaminobacter sp. in agricultural soils exposed to atrazine is due to the characteristic ability of this organism to utilize alkylamines, and therefore atrazine, as sole sources of carbon when the atzABC genes are acquired.  (+info)

Differential modulation of catecholamines by chlorotriazine herbicides in pheochromocytoma (PC12) cells in vitro. (8/193)

Epidemiological, wildlife, and laboratory studies have pointed to the possible adverse health effects of chlorotriazine herbicide (i.e. , atrazine, simazine, and cyanazine) exposure. However, the cellular mechanism(s) of action of these compounds remains unknown. Recently, it was reported by Cooper et al. (2000, Toxicol. Sci. 53, 297-307) that atrazine disrupts ovarian function by altering hypothalamic catecholamine concentrations and subsequently the regulation of luteinizing hormone (LH) and prolactin (PRL) secretion by the pituitary. In this study, we examined the effect of three chlorotriazines on catecholamine metabolism in vitro using PC12 cells. Intracellular norepinephrine (NE) and dopamine (DA) concentrations and spontaneous NE release were measured following treatment with different concentrations of atrazine, simazine (0, 12. 5, 25, 50, 100, and 200 microM) and cyanazine (0, 25, 50, 100, and 400 microM) for 6, 12, 18, 24, and 48 h. Atrazine and simazine significantly decreased intracellular DA concentration in a concentration-dependent manner. Intracellular NE concentration was also significantly decreased by 100 and 200 microM atrazine and 200 microM simazine. Similarly, there was a dose-dependent inhibition of NE release with 100 and 200 microM concentrations of both compounds. Although 100 and 400 microM cyanazine increased intracellular NE concentration, 50, 100, and 400 microM cyanazine significantly increased NE release at 24 and 36 h. In contrast, intracellular DA concentration was decreased by cyanazine, but only at 400 microM. The GABA(A)-receptor agonist, muscimol (0, 0.01, 0.1, and 1.0 microM) had no effect on either the release or on intracellular catecholamine concentrations from 6 through 24 h of treatment. Cell viability was somewhat lower in the groups exposed to 100 and 200 microM atrazine and simazine. However, the reduction in viability was significant only in the highest dose of atrazine used (200 microM) at 24 h. Cyanazine did not have an effect on the viability at any of the doses tested, and the cells were functional, even up to 48 h of exposure. These data indicate that both atrazine and simazine inhibit the cellular synthesis of DA mediated by the tyrosine hydroxylase (TH), and NE mediated by dopamine beta-hydroxylase (DbetaH), and, as a result, there is a partial or significant inhibition of NE release. Cyanazine, on the other hand, stimulated the synthesis of intracellular NE, and not DA. Thus, chlorotriazine compounds presumably act at the enzymatic steps or sites of CA biosynthesis to modulate monoaminergic activity in PC12 cells.  (+info)

Environmental factors can alter DNA methylation and epigenetic modifications in the germline [51, 90]. We studied the effects of the widely used herbicide atrazine (ATZ) on meiosis. In many countries, ATZ is the most common contaminant detected in rivers [19, 72, 92]. ATZ residues are even detected in soil and aqueous environments in countries where it has been banned [59, 102, 103]. Low levels of ATZ metabolites in pregnant women are associated with low birth weight [16, 61]. In mammals, ATZ is metabolized by several groups of xenobiotic-metabolizing enzymes. The metabolism of ATZ interferes with oxidative phosphorylation and cytochrome P450 function, resulting in decreased oxygen consumption [10, 14, 39, 47]. ATZ is known to alter reproductive processes in rodents [96, 101], reptiles [18], birds [104], goats [81], amphibians [28-30] and fish [63, 69]. ATZ targets many tissues, including the testes [67, 68, 101], ovaries [8, 17, 41, 52], brain [5, 7], liver [25, 36, 38, 78]. The effects of ATZ ...
Beyond Pesticides, December 15, 2009) Exposure to the endocrine-disrupting herbicide atrazine triggers the release of stress hormones in rats, according to a new study published in the December 2009 issue of the journal Toxicological Sciences. The researchers believe this may explain how the popular weed killer produces some its harmful reproductive effects. The study, "Characterization of the Hypothalamic-Pituitary-Adrenal Axis Response to Atrazine and Metabolites in the Female Rat," was conducted by the Environmental Protection Agencys (EPA) National Health and Environmental Effects Research Laboratory.. According to a December 4 analysis by Environmental Health Sciences, a foundation-funded journalism organization, the researchers discovered that female rats fed atrazine at the time of ovulation released a flow of stress hormones that are known to interfere with hormones essential for reproduction. The findings reveal one way atrazine may impact female reproduction. Elevated stress hormones ...
The herbicide atrazine is one of the most commonly applied pesticides in the world. As a result, atrazine is the most commonly detected pesticide contaminant of ground, surface, and drinking water. Atrazine is also a potent endocrine disruptor that is active at low, ecologically relevant concentrations. Previous studies showed that atrazine adversely affects amphibian larval development. The present study demonstrates the reproductive consequences of atrazine exposure in adult amphibians. Atrazine-exposed males were both demasculinized (chemically castrated) and completely feminized as adults. Ten percent of the exposed genetic males developed into functional females that copulated with unexposed males and produced viable eggs. Atrazine-exposed males suffered from depressed testosterone, decreased breeding gland size, demasculinized/feminized laryngeal development, suppressed mating behavior, reduced spermatogenesis, and decreased fertility. These data are consistent with effects of atrazine ...
Beyond Pesticides, March 3, 2010) A recently published study in the Proceedings of the National Academy of Sciences finds that male frogs exposed to the herbicide atrazine can become so completely female that they can mate and lay viable eggs. This latest study adds to the growing scientific evidence which shows that atrazine, one of the most common herbicides used in the U.S., disrupts the development and behavior of aquatic animals, and negatively effects their immune, hormone, and reproductive systems. The study, "Atrazine induces complete feminization and chemical castration in male African clawed frogs (Xenopus laevis)," led by Tyrone Hayes, PhD, at the University of California, Berkeley, demonstrates the reproductive consequences of atrazine exposure in adult amphibians.

As tadpoles, the frogs were put in water with 2.5 parts per billion (ppb) of atrazine - a concentration ...
Soluble sugars, which play a central role in plant structure and metabolism, are also involved in the responses to a number of stresses, and act as metabolite signalling molecules that activate specific or hormone-crosstalk transduction pathways. The different roles of exogenous sucrose in the tolerance of Arabidopsis thaliana plantlets to the herbicide atrazine and oxidative stress were studied by a transcriptomic approach using CATMA arrays. Parallel situations of xenobiotic stress and sucrose-induced tolerance in the presence of atrazine, of sucrose, and of sucrose plus atrazine were compared. These approaches revealed that atrazine affected gene expression and therefore seedling physiology at a much larger scale than previously described, with potential impairment of protein translation and of reactive-oxygen-species (ROS) defence mechanisms. Correlatively, sucrose-induced protection against atrazine injury was associated with important modifications of gene expression related to ROS defence
Diaminochlorotriazine (DACT) was the most frequently detected analyte (58% > limit of detection [LOD]) followed by desethyl atrazine (6%), desethyl atrazine mercapturate (3%), atrazine mercapturate (1%), hydroxyl atrazine (1%), atrazine (1%) and desisopropyl atrazine (0.5%). Because of low detection of other analytes, only DACT was included in the exposure-outcome analyses. The adjusted odds of early menarche for girls with DACT exposures≥median was 1.13 (95% Confidence Interval [95% CI]:0.82, 1.55) and exposure < median was 1.01 (95% CI: 0.73, 1.42) compared to girls with exposure < LOD (reference). In the subset that excluded girls with missing data, the adjusted odds of early menarche for girls with DACT exposures≥median was 1.86 (95% CI: 1.03, 3.38) and exposure < median was 1.26 (95% CI: 0.65, 2.24) compared to the reference ...
The Environmental Protection Agency will hold a Scientific Advisory Panel public meeting Tuesday, to review and consider the ecological risks from the use of Atrazine. The product is one of the most widely used herbicides in the United States and it could be banned here. Produced by Swiss agrochemical company Syngenta, Atrazine has been banned in the European Union since 2004, but 80 million pounds of it are applied in the United States each year.. Atrazine is a potent endocrine disruptor that has been shown to cause immunosuppression, hermaphroditism and even complete sex reversal in male frogs at concentrations as low as 2.5 parts per billion. The chemical has been linked to reproductive defects in fish and prostate and breast cancer in laboratory rodents, and epidemiological studies suggest it is carcinogenic to humans. Atrazine is the most commonly detected pesticide in American groundwater.. It is used primarily on corn, sugarcane, rice, sorghum and on golf courses and lawns. Atrazine has a ...
A sensitive chemiluminescence (CL)-based immunoassay technique based on both dipstick and flow injection analytical formats is reported for the detection of atrazine. In the dipstick-based immunoassay technique, antibody (anti-atrazine) was first immobilized on the nitrocellulose membranes. The dipstick was then treated with atrazine and atrazine-horseradish peroxidase conjugate (atra-HRP) to facilitate the competitive binding. The dipstick was further treated with urea-hydrogen peroxide (U-H2O2) and luminol to generate photons. The number of photons generated was inversely proportional to the atrazine concentration. In the flow injection analysis (FIA) format, the antibody was immobilized on protein-A sepharose matrix and packed in a glass capillary column, which functioned as an immunoreactor. Competitive binding of antigen and antibody occurred. The CL signals generated during the biochemical reactions were correlated with atrazine concentrations in the analytical samples. By using dipstick ...
Excessive use of pesticides and herbicides is a major environmental and health concern worldwide. Atrazine, a synthetic triazine herbicide commonly used to control grassy and broadleaf weeds in...
Atrazine is widely used as a selective triazine herbicide for controlling a wide varieties of broad-leaf and grassy weeds [1]. Atrazine herbicide is moderately present in the aquatic environment and has a low rate of biodegradability. Despite the atrazines low water solubility, there is much concern about the contamination of water resources with the highly toxic herbicides [2, 3]. Many studies reported that atrazines half-life in the aqueous phase and groundwater resources ranges from 41 to 237 days and 15 months to 20 years, respectively [4].. The maximum contaminant level for atrazine in drinking water established by the USEPA and WHO is 3.0 and 2.0 \( \mu \)gL−1, respectively [5]. Long-term effects of atrazine include probable human carcinogen, endocrine-disrupter, alteration in vitamins function, hepatotoxicity and renal toxicity [6].. Advanced oxidation processes (AOPs) [7] and photocatalytic oxidation process are efficient methods relying on hydroxyl radicals (OH°) production to ...
Following is a press release from US EPA summarizing important regulatory actions relating to atrazine.. "In January 2003, EPA issued an Interim Re-registration Eligibility Decision (IRED) for the widely-used pesticide atrazine, culminating a multi-year assessment. Specific risk mitigation measures were described for potential human health concerns, however the document committed to future development of measures for mitigating ecological risks. As a follow-up, an addendum to the January document is being released. The addendum discusses ecological monitoring and risk mitigation within sensitive watersheds, the most current scientific information regarding potential effects of atrazine on amphibians and recent scientific work about the potential association between atrazine exposure and the incidence of prostate and other cancers.. "Specifically to target monitoring of ecologically vulnerable watersheds, the manufacturers of atrazine are required to monitor residue levels in 40 indicator ...
atrazine chlorohydrolase: an atrazine-dechlorinating enzyme with restricted substrate specificity & contributes to the microbial hydrolysis of atrazine to hydroxyatrazine in soils & groundwater
The PELAGIE cohort. The PELAGIE cohort included 3,421 pregnant women from Brittany from 2002 through February 2006. Enrollment started in the district of Ille-et-Vilaine, continued in Finistère, and ended in Côtes dArmor. Gynecologists, obstetricians, and ultrasonographers recruited women during consultations in early pregnancy, informing them about the nature of the study and asking them to participate (after providing written consent). Women were enrolled before the 19th week of gestation after providing written informed consent and completing a questionnaire at home concerning family social and demographic characteristics, diet, and lifestyle. Women were asked to return the questionnaire by mail, along with a first-morning-void urine sample that they collected and transferred into two vials containing nitric acid (to inhibit bacterial proliferation). Samples were mailed to the study laboratory (INSERM U625, Rennes, France) in a prestamped package at ambient temperature, with routine ...

Atrazine molecular imprinted polymers (MIPs) were comparatively synthesized using identical polymer formulation by far-infrared (FIR) radiation and ultraviolet (UV)-induced polymerization, respectively. Equilibrium binding experiments were carried out with the prepared MIPs; the results showed that MIPuv possessed specific binding to atrazine compared with their MIPFIR radiation counterparts. Scatchard plots of both MIPs indicated that the affinities of the binding sites in MIPs are heterogeneous and can be approximated by two dissociation-constants corresponding to the high- and low-affinity binding sites. Moreover, several common pesticides including atrazine, cyromazine, metamitron, simazine, ametryn, terbutryn were tested to determine their specificity, similar imprinting factor (IF) and different selectivity index (SI) for both MIPs. Physical characterization of the polymers revealed that the different polymerization methods led to slight differences in polymer structures and performance by
The present study investigates the efficiency of a sustainable treatment technology, the electrophotocatalytic (EPC) process using innovative photoanode TiO2−x prepared by a magnetron sputter deposition process to remove the herbicide atrazine (ATZ) from water. The coexistence of anatase and rutile were identified by X-ray diffraction (XRD) and the presence of oxygen vacancies reduce the value of the observed bandgap to 3.0 eV compared to the typical 3.2 eV TiO2, this reduction is concomitant with a partial phase transition which is probably responsible for the increase in photoactivity. The experimental results with an initial concentration of ATZ (100 μg L−1) show that more than 99% of ATZ oxidation was obtained after 30 min of treatment and reaction kinetic constant was about 0.146 min−1. This good efficiency indicates that EPC process is an efficient, simple and green technique for degradation of pesticides such as ATZ in water. The analysis with liquid chromatography technique ...
Tese de mestrado em Biologia (Biologia Celular e Biotecnologia), apresentada à Universidade de Lisboa, através da Faculdade de Ciências, 2008Atrazine has been used worldwide since 1952 and is frequently detected above the levels established by regulatory authorities in consumption waters. Therefore, and because of its ecotoxicological properties, its use has been forbidden in most European countries, including Portugal. However, atrazine is still used in many countries worldwide. The main purpose of the present work was to examine the efficacy of the atrazinedegrading bacteria Pseudomonas sp. ADP (P. ADP) as bioaugmentation agent in soils contaminated with high doses (~20x and ~50xRD; RD Recommended dose) of the commercial formulation, Primextra S-Gold, that contains atrazine, and also S-metolachlor and benoxacor as main active ingredients. It was also tested the effect of combining bioaugmentation and biostimulation using soil amendment with trisodium citrate in open soil microcosms, with ...
Atrazine exposure during embryonic development could cause later reproductive problems for female zebrafish, as well as physical deformations in their offspring, according to new research from Purdue University.
The herbicide atrazine is a potent endocrine disrupter that chemically castrates and feminizes exposed male amphibians. Further, when combined with other pesticides, exposure results in a hormonal stress response that leads to retarded growth and development, and immuno-suppression. The immuno-suppression results in increased disease rates and mortality. Though many factors likely contribute to amphibian declines, pesticides likely play an important role even in populations that appear to decline for other reasons, such as disease. Pesticides like atrazine are ubiquitous, persistent contaminants. Effects of exposure have been shown in every vertebrate class examined (fish, amphibians, reptiles, and mammals) via common mechanisms. These observations demonstrate the critical impact that pesticides have on environmental health. Furthermore, reproductive cancers and birth defects associated with exposure to many of these same chemicals (e.g. atrazine) via identical mechanisms demonstrate that the ...
Reliable predictions of the fate and behaviour of pesticides in soils is dependent on the use of accurate equilibrium sorption constants and/or rate coefficients. However, the sensitivity of these parameters to changes in the physicochemical characteristics of soil solids and interstitial solutions remains poorly understood. Here, we investigate the effects of soil organic matter content, particle size distribution, dissolved organic matter and the presence of crop residues (wheat straw and ash) on the sorption of the herbicides atrazine and isoproturon by a clay soil. Sorption Kds derived from batch equilibrium studies for both atrazine and isoproturon by ,2 mm clay soil were approximately 3.5 L/kg. The similarity of Kocs for isoproturon sorption by the ,2 mm clay soil and ,2 mm clay soil oxidised with hydrogen peroxide suggested that the sorption of this herbicide was strongly influenced by soil organic matter. By contrast, Kocs for atrazine sorption by oxidised soil were three times ...

Journal of Agricultural and Food Chemistry. 52:6552-6556. Interpretive Summary: Characterization of pesticide bioavailability, particularly in aged soils, is of continued interest because this information is necessary for environmental risk assessment of pesticides. The objective of this study was to correlate atrazine (a triazine herbicide) residue bioavailability in aged soils, as determined by solvent extraction methods, to atrazine mineralization by an atrazine-degrading bacterium. We identified an extraction procedure using aqueous methanol (a water/alcohol mixture) that can characterize atrazine bioavailability in dissimilar aged soils, which in turn may be useful to determine bioavailability of other compounds in soils, especially other triazine herbicides. Scientists now a relatively easy and inexpensive technique to determine the amounts of ...
Atrazine (ATR) is an herbicide that has been shown to have adverse reproductive effects including alterations in levels of pituitary hormones such as prolactin (prl) and luteinizing hormone (LH) in female LE rats when administered at doses of 200 mg/kg/day for 1 and 3 days. Because the action of prl in promotion of progesterone secretion is essential for the initiation of pregnancy in rats, this study was designed to examine the effect of exposure to ATR during early pregnancy on implantation and short-term pregnancy maintenance. Rats were divided into two groups representing periods of dosing with ATR prior to the diurnal or nocturnal surges of prl. Within each group, four groups consisting of four strains of rats [Holtzman (HLZ); Sprague Dawley (SD); Long Evans (LE); Fischer 344 (F344)] were each further subdivided into four ATR dosages. Rats were dosed by gavage with 0, 50, 100, or 200 mg/kg/day ATR on days 1-8 of pregnancy (day 0 = sperm +). All animals were necropsied on day 8 or 9 of ...
Atrazine is a common but controversial pre- and post-emergent herbicide used to control broadleaf and grass-like weeds in commercial farming fields. It is also a component of granular weed and feed lawn products designed for the home and landscape gardener. The use of atrazine is banned in Europe due to concerns over ...
Adsorption of two widespread emerging water contaminants (atrazine and paracetamol) onto three different activated carbons was investigated. The carbons were characterized and the influence of their physicochemical properties on the adsorption performance of atrazine and paracetamol was evaluated. The adsorption equilibrium data were fitted to different adsorption isotherm models (Langmuir, Freundlich, and Dubinin-Radushkevich) while the adsorption rates were described using three different kinetic models (pseudo second order, intraparticle diffusion and a new approach based on diffusion-reaction models). The results indicated that hydrophobic character of the compounds does not affect the sorption capacity of the tested carbons but does influence the uptake rate. The model proposed, based on mass balances, lead to interpret and compare the kinetic of different adsorbents in contrast to classical empirical models. The model is a simple and powerful tool able to satisfactorily estimate the ...

Oh, the beleaguered frogs. You probably already know that amphibian species are declining around the world. You have probably seen the depressing photos of deformed frogs trying to get through life with too many (or too few) legs. You may even have seen Dr. Tyrone Hayes breathtaking presentation on how the herbicide atrazine turns boy frogs in to hermaphrodite frogs.. This week the N & O ran a story about a new study that reinforces the theory that farm runoff is causing the deformed limbs. Excess nutrients in the water lead to lots more parasites in the water that turn normal tadpoles into sickly, deformed adult frogs.. One of the questions about this research is, how come the trematodes make frogs so sick? Theyre not a new pathogen - theyve always been in the frogs environments. Its just that lately the frogs cant seem to fight them off. Another stumper: if its one disease deforming the frogs, why does it affect so many species? Leopard frogs, bullfrogs, wood frogs, and many others have ...
Based on submission by Monika Frey to the MaizeGDB and the Maize Genetics Cooperation Newsletter. Function Maize gene for first step in biosynthesis of benzoxazin, which aids in resistance to insect pests, pathogenic fungi and bacteria. First report Hamilton 1964, as a mutant sensitive to the herbicide atrazine, and lacking benzoxazinoids (less than 1% of non-mutant plants). Mutations in the bx1 gene reduce the resistance to first generation European corn borer that is conferred by benzoxazinoids. Molecular characterization reveals that the BX1 protein is a homologue to the alpha-subunit of tryptophan synthase. The reference mutant allele has a deletion of about 900 bp, located at the 5-terminus and comprising sequence upstream of the transcription start site and the first exon. A second mutant allele is given by a Mu transposon insertion in the fourth exon (Frey et al. 1997 ). Gene sequence diversity analysis has been performed for 281 inbred lines of maize, and the results suggest that bx1 is ...
Atrazine is the worlds most widely used herbicide. It is used to control weeds in plantations, on roadsides, in parks, gardens, orchards and pastures, etc - lots of places where children play. It is notorious for its tendency to contaminate groundwater, with a consequent deleterious effect on human health as documented by the World Health Organisation. Because it is a systemic poison (organochlorine), its residues penetrate the flesh of fruit and vegetables and cannot be washed off. The Australian Medical Association is opposed to Atrazine spraying.. Research 4 has indicated that atrazine is associated with prostrate, ovarian and creast cancer and also damages the endocrine system, functioning as a synthetic hormone disruptor. As a hormon mimic it can block, antagonise, compete with, or mimic hormones at cellular level. This may lead to reproductive and endocrinal effects. Atrazine has also demonstrated cardiac toxicity in experimental animals. Exposure may lead to abdominal pain, impaired ...
Given that water is oxidized indirectly by P680+ and the build up of intermediates caused by inhibition in Qb would not allow P680 to deposit its extra electron into the beginning of the electron transport chain, water would not be oxidized/split into 2H+ and (1/2)O2 because P680 would not become P680+. So this inhibition would halt the production of oxygen, correct?. Given that, I would say that the production of O2 would be more immediately halted than that of ATP, especially since ATP synthase would continue to function until the electrochemical gradient between the stroma and thylakoid space was spent, and would not be immediately affected by inhibition in Qa (although the electron transport chain which maintains the electrochemical gradient would be compromised and thus indirectly ATP synthase would be affected).. Is my reasoning correct?. ...
Atrazine (2-chloro-4-ethytlamino-6-isopropylamine-1,3,5-triazine; ATR) is widely used as a broad-spectrum herbicide. Animal studies have demonstrated that ATR exposure can cause cell death in dopaminergic neurons. The molecular mechanisms underlying ATR-induced neuronal cell death, however, are unknown. In this study, we investigated the autophagy and apoptosis induced by ATR in dopaminergic neurons in vivo. Wistar rats were administered with ATR at doses of 10, 50 and 100 mg/kg body weight by oral gavage for three months. In terms of histopathology, the expression of autophagy- and apoptosis-related genes as well as proteins related to the Beclin-1/B-cell lymphoma 2 (Bcl-2) autophagy and apoptosis pathways were examined in the rat nigrostriatal dopaminergic system. We observed degenerative micromorphology indicative of neuronal apoptosis and mitochondrial autophagy by electron microscopy in ATR-exposed rat striatum. The rat ventral mesencephalon in the ATR-exposed groups also showed increased

Over 200,000 cases of invasive breast cancer are diagnosed annually; herbicide contaminants in local water sources may contribute to the growth of these cancers. GPR30, a G protein coupled receptor, was identified as a potential orphan receptor that may interact with triazine herbicides such as atrazine, one of the most commonly utilized chlorotriazines in agricultural practices in the United States. Our goal was to identify whether chlorotriazines affected the expression of GPR30. Two breast cancer cell lines, MDA-MB-231 and MCF-7, as well as one normal breast cell line, MCF-10A, were treated with a 100-fold range of atrazine, cyanazine, or simazine, with levels flanking the EPA safe level for each compound. Using real-time PCR, we assessed changes in GPR30 mRNA compared to a GAPDH control. Our results indicate that GPR30 expression increased in breast cancer cells at levels lower than the US EPA drinking water contamination limit. During this treatment, the viability of cells was unaltered. In

Chenopodium albumL. is a major weed in spring-planted crops in the temperate regions of the world. Since 2000, farmers have reported an unsatisfactory control of this weed in sugar beet fields in Belgium, France and The Netherlands. Frequently, the survivingC. albumplants are resistant to metamitron, a key herbicide in this crop. Metamitron resistance inC. albumis caused by a Ser264 to Gly mutation in the psbA gene on the chloroplast genome, which prevents binding of metamitron to its target site. This mutation causes also resistance to other herbicides with a similar mode of action, like metribuzin -applied in potato- and atrazine in particular. Atrazine has been applied very frequently in maize in the 1970s and the 1980s, but is now banned in Europe due to environmental reasons. The persistent use of atrazine in maize confronted Belgian and other European farmers in the early 1980s with atrazine resistantC. albumwith the same Ser264 to Gly mutation. The problems with atrazine resistantC. ...

To uncover which factors govern pesticide compound concentrations in a chalk aquifer, we develop a methodology based on time series analyses, uni- and multivariate statistics accounting for concentrations below detection limits. The methodology is applied to long records (1996-2013) of a restricted compound (bentazone), three banned compounds (atrazine, diuron and simazine) and two metabolites (deethylatrazine (DEA) and 2,6-dichlorobenzamide (BAM)) sampled in the Hesbaye chalk aquifer in Belgium. In the confined area, all compounds had non-detects ...
Atrazine, a widely used agricultural herbicide, not only can alter hormone levels in the developing frogs, but also perturb their physical development — and lead to an excess number of females, researchers report. Their new findings may help explain observations reported by a number of other research groups that at least in frogs, fairly low concentrations of atrazine can induce a feminization — or demasculinization.
Endocrine disrupting chemicals (EDCs) are synthetic and natural compounds that, when absorbed by an organism, can change the function of the endocrine system (Stuart, 2006). Researchers all over the world are studying the potentially harmful effects of these chemicals, particularly those effects on fish and amphibians. These effects include, reproductive, neurological, and immunologic dysfunction, among others (Harding et al. 2006).Research in our lab has focused on the reproductive effects of EDCs in aquatic habitats. Fish and amphibians are exposed to EDCs through their environment. To our knowledge, the concentrations of three specific EDCs-- atrazine, 17 α ethynylestradiol, and 17 β estradiol--have not been determined for the Pike River in Kenosha, WI. We hypothesize that surface waters in Lake Michigan will have higher levels of 17α ethynylestradiol and 17β estradiol. In agricultural areas, we hypothesize that atrazine will be detected in higher concentrations. Finally, we hypothesize ...

Health experts call Roundup a probable carcinogen for humans. Glyphosate, found in worlds most widely used herbicide, classified as probable carcinogen by cancer research experts. by Renee Lewis, (published in Al Jeezera America on March 21, 2015). The most widely used herbicide in the world, glyphosate, the active ingredient in the Monsanto product Roundup, was classified as "probably carcinogenic to humans," in a report released Friday by cancer researchers affiliated with the World Health Organization.. The International Agency for Research on Cancer (IARC) announced its assessment of glyphosate after convening a meeting this month of 17 cancer experts from 11 countries. They looked at the available scientific evidence on five different pesticides, including glyphosate, to determine whether to classify them as carcinogens. Carcinogens are substances that can lead to cancer under certain levels of exposure. ...
High-throughput methods for structural genomics have produced an increasing number of protein structures to be solved by X-ray crystallography. The abundance of protein structure information in the Protein Data Bank (PDB) has increased the need and desire for structure-based function prediction [1] and has contributed to structure-based drug design [2]. However, two problems remain regarding the prediction of enzyme function. First, proteins within a superfamily, which are usually expected to share the same catalytic properties, can catalyze different reactions. There are reports that enzymes with 98% sequence identity, such as melamine deaminase and atrazine chlorohydrolase, may catalyze different reactions [3]. Second, two enzymes belonging to different superfamilies or fold classes can catalyze almost identical reactions [4].. The function of a protein can be affected by a small number of residues in a localized region of its three-dimensional structure [5]. Moreover, the specific arrangement ...

This study aimed at determining the effects of cigarette smoke exposure during pregnancy on the morphology of the developing heart. Twelve adult female Wistar rats were used for the study. The animals were time mated and grouped into three: a control (A) and two treatment groups (B and C). The treatment groups were exposed to smoke from 2 sticks of cigarette (St. Moritz®) on days 8 - 14 (Group B) and days 15-21 (Group C) of the gestation. Each stick of cigarette contained an average of 0.8375 g of tobacco. The pregnant rats were allowed to litter, and at postnatal day 15, pups from all the groups were sacrificed by cervical dislocation, the chest wall was dissected and the heart was excised and either placed in 10% formal saline fixative for histological preparation using Haematoxylin and eosin staining techniques, or 0.25 M cold sucrose solution and homogenised for enzyme study on the activity of lactate dehydrogenase using the colorimetric method.

Herbicides pose a potential threat to aquatic ecosystems, especially to phototrophic organisms such as benthic diatoms. Benthic diatoms may be a valuable indicator of the toxic impacts of herbicides in aquatic systems. However, this requires information on the herbicide sensitivity of a wide range of freshwater benthic diatom taxa. Unfortunately this information is only available for a limited number of species as current methods of developing new algae toxicity tests on individual taxa are lengthy and costly. To address this issue, we developed a new rapid toxicity test method to test natural benthic communities, from which the relative herbicide sensitivity of many individual taxa can be derived. This involved the collection of natural benthic communities from rocks in situ, which were placed directly into laboratory toxicity tests. Sensitivity data for several diatom genera in a 48 hour exposure toxicity test were produced, without the need for cultures or multiple site visits. After exposure ...
Xenoestrogens and Ovarian CancerRecent studies also link xenoestrogens to ovarian cancer. Because the raw material for estrogen production is cholesterol, the ovary, like the breast, is a repository of fat-soluble contaminants. Dioxin, for example, has been found in the fluid surrounding human eggs extracted for test-tube fertilisation.Studies done in 1989 showed that estrogen increases the rate of growth of ovarian tumour cells by 50% compared to those not treated with estrogen.In the same year, Italian researchers studying the health and habits of women farmers in northern Italy discovered that women farmers exposed to triazine herbicides, such as atrazine, had a three- to- four-times higher risk for ovarian cancer.Both these lines of research suggests that triazine herbicides may be acting as xenoestrogens in the ovaries, a hypothesis that has been supported by more recent research.However, many of the existing reports suffer from small sample sizes, difficulty determining actual exposures, ...

Most natural products and xenobiotic molecules, irrespective of their molecular or structural complexity, are degradable by some microbial species/associations within particular environments. Atrazine- and selected petroleum hydrocarbon (benzene, toluen~ and 0-, m- and p-xylene (BTX))-degrading associations were enriched and isolated"trom atrazine- and petroleum hydrocarbon (PHC)-contaminated KwaZuluNatal loamy and sandy soils, respectively. In total, eight pesticide- and forty BTXcatabolizing associations were isolated. Electron microscopy revealed that, numerically, rods constituted the majority of the populations responsible for both atrazine and PHC catabolism. Cocci and, possibly, spores or fungal reproductive bodies were observed also. For the BTX-catabolizing associations, the population profiles appeared to be dependent on the enrichment pH and the molecule concentration. After combining selected associations, to ensure that all the isolated species were present, batch cultures were made ...
Sorry hattifattener, I was out of town for a few days. Glyphosate has been linked to Non-Hodgkins Lymphoma and to Hairy Cell Leukemia, and other health effects such as miscarriages. There also seems to be evidence that it harms naturally beneficial bacteria and fungi in the soil, such as those that fix nitrogen. Denmark has banned its use. There are much worse chemicals out there such as Atrazine. Nevertheless, glyphosate is likely not benign. The science about its ill effects or safety is by no means crystal clear. The worst effects are likely felt by farmers, lawn service personnel and others whose exposure greatly exceeds the average. Still, if vinegar or boiling water works then that would seem to be preferred ...

The sabotage of science is now a routine part of American politics. The same corporate strategy of bombarding the courts and regulatory agencies with a barrage of dubious scientific information has been tried on innumerable occasions -- and it has nearly always worked, at least for a time. Tobacco. Asbestos. Lead. Vinyl chloride. Chromium. Formaldehyde. Arsenic. Atrazine. Benzene. Beryllium. Mercury. Vioxx. And on and on. In battles over regulating these and many other dangerous substances, money has bought science, and then science -- or, more precisely, artificially exaggerated uncertainty about scientific findings -- has greatly delayed action to protect public and worker safety. And in many cases, people have died. Tobacco companies perfected the ruse, which was later copycatted by other polluting or health-endangering industries. One tobacco executive was even dumb enough to write it down in 1969. "Doubt is our product," reads the infamous memo, "since it is the best means of competing with ...

Image above: Commercial spraying of RoundUp on food crops genetically designed to withstand the herbicide is prevalent. From (http://indianapublicmedia.org/eartheats/effects-gm-pesticide-products). The chemical at the heart of the planets most widely used herbicide -- Roundup weedkiller, used in farms and gardens across the U.S. -- is coming under more intense scrutiny following the release of a new report calling for a heightened regulatory response around its use. Critics have argued for decades that glyphosate, the active ingredient in Roundup and other herbicides used around the globe, poses a serious threat to public health. Industry regulators, however, appear to have consistently overlooked their concerns.. A comprehensive review of existing data released this month by Earth Open Source, an organization that uses open-source collaboration to advance sustainable food production, suggests that industry regulators in Europe have known for years that glyphosate, originally introduced by ...

The herbicides most commonly found in urban streams, in addition to atrazine and metolachlor, are simazine, prometon, 2,4-D, diuron, and tebuthiuron, all of which are commonly used in nonagricultural settings for maintenance of roadsides, commercial areas, lawns, and gardens. Prometon and 2,4-D have among the highest frequencies of urban use. Of the urban herbicides, 2,4-D, simazine, and diuron also have substantial agricultural use, ranking in the top 25 nationally. Diuron and 2,4-D were not detected as frequently as other compounds with similar use, probably because the analytical method for these two compounds is less sensitive and resulted in fewer detections than for other compounds, even when concentrations were similar. As in streams, the most frequently found herbicides in shallow ground water in urban areas were atrazine, DEA, simazine, and prometon. Unlike streams, however, metolachlor was seldom detected, probably because of its lower urban use and lower persistence in the environment ...
EPA is releasing the draft ecological risk assessments for atrazine, propazine and simazine, which evaluate risks to animals and plants including, amphibians, birds, mammals, fish, reptiles, aquatic invertebrates, aquatic plant communities, and terrestrial plants. All three pesticides are in the triazine class of pesticides.. EPA invites stakeholders to comment on the draft ecological risk assessments. The draft assessments are currently available on the agencys website. EPA will be accepting public comments until October 4, 2016 (extended from the original closing date of August 5). After receiving and reviewing public comments, the agency will amend the assessments, as appropriate. EPA will have atrazines assessment peer reviewed by the Scientific Advisory Panel in 2017.. With regard to atrazine, the herbicide is one of the most widely used agricultural pesticides in the United States. It is used primarily on corn and sorghum in the Midwest and sugarcane in the South Central and Southeastern ...
0.375, 0.500 and 0.625 kg imazapyr/ha and combinations of 5.0 kg atrazine + 1.9 kg amitrole or 8.0 kg diuron + 1.9 kg amitrole/ha were evaluated for roadside control of Cruciferae, Umbelliferae, Compositae, Papilionaceae [Leguminosae] and grasses (mostly Brachypodium distachyon and Lophochloa phleoides). Treatments were applied post-em. to weeds 40-50 cm tall. Imazapyr acted very slowly with the first symptoms visible only 4 weeks after application and complete control evident 4 months later. The highest application rate achieved complete control of all annual weeds and inhibition of growth of the perennial Andropogon distachyos. Atrazine + amitrole and diuron + amitrole provided good control of annual weeds.

An investigation of the occurrence of phosporus, other nutrients, and triazine herbicides in water samples from the Hillsdale Lake Basin in northeast Kansas was conducted from May 1994 through May 1995. Point-source and nonpoint-source contributions of these water-quality constituents were estimated by conducting synoptic sampling at 48 sites in the basin during five periods of low- flow conditions. Samples were collected for the determination of nutrients, including total phosphorus as phosphorus, dissolved orthophosphate as phosphorus, total nitrite plus nitrate as nitrogen, and total ammonia plus organic nitrogen as nitrogen, and for selected triazine herbicides. On the basis of criteria developed by the Kansas Department of Health and Environment, the Hillsdale Water-Quality Protection Project established a goal to maintain water quality in the tributaries of the Hillsdale Lake Basin at a mean annual low-flow total phosphorus concentration...
