N2 - Organochlorine (OC) contaminants including polychlorinated biphenyls (PCBs) and p, p-dichlorodiphenyldichloroethylene (DDE) have been associated with immune modulation in wild fish-eating birds from the Great Lakes. The objective of this study was to evaluate the immune function of juvenile chickens after in ovo exposure to PCB 126 or an environmentally relevant OC mixture extracted from eggs of double crested cormorants (Phalacrocorax auritus) from Green Bay, Lake Michigan, USA. Fertile white leghorn chicken (Gallus domesticus) eggs were injected before incubation with 0.55-1.79 ng TCDD equivalents (TEQ)/egg PCB 126 and 1.2-4.9 ng TEQs/egg of ...
Concentrations of organochlorine compounds detected in fish tissue from many eastern Iowa streams and rivers indicate the long-term effects of previous human activities, which are not often detected by chemical analyses of water or sediment. With the exception of McLoud Run at Cedar Rapids, streams and rivers sampled during the study drain agricultural lands. Land use has not changed substantially since these compounds were commonly used, although prior coal mining activities upstream from Cedar Creek near Oakland Mills (site 14) have ceased. Despite similar land-use characteristics throughout the study unit, concentrations of organochlorine compounds in fish tissue vary widely. In the graph above, organochlorine concentrations are presented in micrograms per kilogram (mg/kg), units that are equivalent to parts per billion.. Fish tissue from the Wapsipinicon River near Tripoli (site 1) was comparatively uncontaminated, containing only a small amount of a DDT degradation product. This condition ...
BACKGROUND: We performed a cross-sectional study of associations between personal characteristics and lipid-adjusted serum concentrations of certain PCB congeners and chlorinated pesticides/metabolites among 323 pregnant primiparous women from Uppsala County (age 18-41 years) sampled 1996-1999. METHODS: Extensive personal interviews and questionnaires about personal characteristics were performed both during and after pregnancy. Concentrations of organochlorine compounds in serum lipids in late pregnancy were analysed by gas chromatography. Associations between personal characteristics and serum levels of organochlorine compounds were analysed by multiple linear regression. RESULTS: Participation rate was 82% (325 of 395 women). Serum concentrations of PCB congeners IUPAC no. 28, 52, 101, 105 and 167, and o, p-DDT and -DDE, p, p-DDT and -DDD, oxychlordane, and gamma- and alpha-HCH were in many cases below the limit of quantification (LOQ). No statistical analysis of associations with personal ...

Exposure to persistent organic pollutants (POPs) and related compounds such as PCBs, brominated flame retardants, organochlorine pesticides and PAHs is regarded as an important environmental risk factor for humans. Recently concerns about POPs resulted in the international protocol called the Stockholm Conve
PAHs were examined because these compounds are known to cause breast cancer in rodents, and a few small human studies have suggested a possible association between these chemicals and increased risk of breast cancer. Women can be exposed to PAHs by breathing in cigarette smoke, and exhaust from cars, trucks and planes, and by eating grilled and smoked foods. Starting in 1996, Gammon and her colleagues collected blood samples from 1,508 women in Nassau and Suffolk counties who were newly diagnosed with breast cancer, and a similar number of women who did not have cancer. The blood samples were checked for direct evidence of exposure to organochlorine compounds and PAHs, both of which leave traces in the body for months or years.. Study participants also completed a questionnaire, and at some of the womens homes, researchers collected samples of house dust, tap water and yard soil to test for organochlorine compounds and PAHs. Exposure to PAHs causes the chemicals attach to DNA, creating ...
Organochlorines are lipophylic molecules that accumulate in the fat where they remain for years. During weight loss, they are mobilized and their concentration increases in blood. The present work tests, in transgenic estrogen-reporter mice (ERE-tK-LUC), whether this increase is sufficient to modulate the estrogen receptors (ERs) in the whole body. Three weak estrogens were studied: p,p DDT [1,1,1-trichloro2,2-bis(p-chlorophenyl) ethane], p,p DDE [1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene], and betaBHC [beta-benzene-hexachloride]. Dose-dependent analysis of reporter expression (luciferase) were performed in tissues of acutely treated mice. A body snap of ER activation was obtained. All these chemicals modulated the reporter, although with a different efficiency and depending upon the tissue analyzed. Induction was confirmed in the liver by determining the expression of the endogenous progesterone receptor (PR) gene, at the dose and time point at which the luciferase gene was maximally ...

One or more organochlorine compounds were detected in all women in the LIBCSP, although median levels were as much as 10-fold lower than those reported earlier in the 20th century. Multivariate models reconciled the different directions of correlations of DDE and PCB with BMI that were found in simple or age-adjusted correlations (Tables 1 and 2; Fig. 2), in a manner consistent with the pharmacokinetic models. When both BMI and weight gain were included in multivariate models, the direction of the associations was identical for DDE and PCB. Therefore, the statistical models corrected the apparent positive association of DDE with BMI-gain (e.g., Fig. 3) to a negative coefficient in the model (e.g., Table 4), whereas at the same time, after multivariate adjustment, the inverse correlation of PCBs with BMI became positive.. From predicted organochlorine model shown in Fig. 3, highest DDE levels were in women who were heaviest, had the least adult weight gain, and did not lactate. Lowest levels were ...

The dangers of organochlorines and a proposed solution. Pandoras Poison presents a solution to one of the most insidious environmental problems of our time: the global build-up of toxic chemicals. Everywhere on the planet, hundreds of industrial chemicals called organochlorines are accumulating in the environment, the food supply, and our bodies. These substances-such infamous pollutants as dioxins, PCBs, and DDT, along with thousands of lesser-known hazards-are produced when chlorine gas is used to make plastics, paper, pesticides, and many industrial chemicals. In a thorough and accessible analysis, biologist Joe Thornton shows how global organochlorine pollution is already contributing to infertility, immune suppression, cancer, and developmental disorders in humans and wildlife.Thornton proposes a major shift in environmental science and policy. He shows that the current framework radically overestimates the ability of science and technology to address the
ABSTRACT. Background: The purpose of this study was to evaluate the association among serum organochlorine pesticide residues, glutathione S-transferase M1 genetic polymorphism and female breast cancer. Methods: A 1:1 matched case-control study of 140 newly diagnosed breast cancer patients and 140 non-cancer female patients who consulted the five largest hospitals in the Tangshan city from September 2006 to October 2007. Results: The result showed higher risk of breast cancer among subjects with higher levels of serum DDT and HCH residue, the OR was 3.18 (95%CI, 1.11 - 9.07) and 5.02 (95%CI, 1.64 - 16.56).The value of ORe associated with single environmental factor DDT high residues, and ORg associated with single GSTM1 deletion genotype were respectively 3.86 (1.20 - 12.47) and 1.34 (0.36 - 5.08). The OReg associated with combined action of two factors was 5.59 (1.63 - 18.90), and the value of interaction parameters (γ) equaled 1.24.

Beyond Pesticides, June 20, 2011) In a study published this week in the journal Pediatrics, researchers report findings that link mothers exposure to organochlorine pesticides during pregnancy with infants sizes at birth. The trend shows that the more mothers are exposed to the pesticides during pregnancy, the higher the chances are for reduced birth weight and length of their newborns. Comprising a total of 494 women and infants in Valencia, Spain from the years 2003-2006, the study evaluates umbilical cord blood for residues of four pesticides or pesticide degradates: DDT, DDE, hexachlorobenzene (HCB), and beta-hexachlorocyclohexane. The results show that a 10-fold increase in pesticide concentrations in the blood corresponds to a reduction in birth weight of 2-4 ounces.. Additional results are correlated to specific pesticides. Higher concentrations of DDT results in a reduction in head circumference of 0.26cm, which the researchers call a significant decrease. Additionally, a decrease of ...
We are constantly exposed to these toxins in our own lifestyles but they are also found in the soil and within the animals and animal products we eat. Aside from overly acidifying the bodys blood when these toxins are released, th accumulation of these toxins can also depress the function of thyroid which greatly affects metabolism on its own. The Physical Activity Sciences Laboratory in Canada did a study on this here:http://toxsci.oxfordjournals.org/content/67/1/46.full where it showed: Organochlorine compounds are released from body fat into the bloodstream during weight loss. Because these compounds may impair thyroid status, which is implicated in the control of resting metabolic rate (RMR), the aim of this study was to determine if the augmentation in plasma organochlorine concentrations might be associated with the decrease in serum T(3) concentration and RMR observed in response to body weight loss. Plasma organochlorine concentrations, serum T(3) concentration, and RMR were measured ...

AU - Lim, Kyung Min. AU - Jee, Sun Ha. PY - 2017/7/1. Y1 - 2017/7/1. N2 - It is still unclear whether persistent organic pollutants (POPs) exposure increases the prostate cancer incidence risk. This prospective cohort study evaluated the associations between serum POPs concentrations and prostate cancer risk. Within a case-cohort study, we identified 110 people diagnosed with prostate cancer and randomly selected 256 sub-cohort participants without prostate cancer. Serum concentrations of 32 polychlorinated biphenyl (PCB) congeners and 19 organochlorine pesticides (OCPs) were measured. The hazard ratios (HRs) and 95% confidence interval (95% CI) for determining the associations between POPs and risk of prostate cancer were estimated using the weighted Cox regression model. Compared to the lowest tertile, ...
Earlier this week, Slate reported that the EPA is considering a new rule for 2016 that could impact the use of methylene chloride (also known as dichloromethane), a chemical commonly found in paint strippers. The rule could result in anything from new warning label requirements to an outright ban.. According to OSHA, workers using methylene chloride are at increased risk of developing cancer, adverse effects on the heart, central nervous system and liver, and skin or eye irritation. While the Slate piece emphasized the risk of sudden, fatal heart attacks, methylene chloride can also pose serious health dangers when absorbed through the skin. (Methylene chloride will eat through latex gloves, so workers need rubber or PVA gloves to stay protected.) In recent years, OSHA has issued hazard alerts for methylene chloride, with a special focus on the dangers it poses for workers engaged in bathtub refinishing. According to OSHA, at least 14 American workers died refinishing bathtubs due to methylene ...

Phospholipid and phosphoinositide phosphorylation pathways have been shown to be of crucial importance on producing lipid mediators. The earlier findings reported on lipid molecules playing roles in different metabolic pathways used to assign them the exclusive role of second messenger generators. Several researchers have recently described how direct interaction of phospholipids and phosphoinositides with molecules or organelles, without the need for producing second messenger molecules, is responsible for their mechanism of action. Organophosphate and organochlorine pesticide toxicity mechanisms have been extensively studied in relation to their well known effects on cholinesterase activities and on the alterations of electric activity in the nervous system of different organisms respectively. There is little but consistent evidence that some compounds, including in both groups of pesticides, are also able to interact with phospholipid and phosphoinositide phosphorylation pathways in
Organochlorine contaminants including 12 polychlorinated biphenyl (PCB) congeners and 18 insecticides were determined in water, pore water and sediments of the Jiulong River Estuary and Western Xiamen Sea, China. The results showed that the levels of the total PCBs ranged from non-detectable to 1500 ng l-1 in water, from 209 to 3870 ng l-1 in pore water, and from 2.78 to 14.8 ng g-1 dry weight in sediments. Total organochlorine insecticide concentrations were from below the limit of detection to 2480 ng l-1 in water, from 267 to 33400 ng l-1 in pore water, and from 4.22 to 46.3 ng g-1 dry weight in sediments. Concentrations of PCBs and insecticides in pore water were significantly higher than those in surface water, due to the high affinity of these hydrophobic compounds for sediment phase. The PCB congeners with the highest concentrations were CB153, CB180 and CB194, which together accounted for 6887% of total PCBs in water, pore water and sediment. Among the hexachlorocyclohexane (HCH) ...

Exposure to methylene chloride occurs mostly from breathing contaminated air, but may also occur through skin contact or by drinking contaminated water. Breathing in large amounts of methylene chloride can damage the central nervous system. Contact of eyes or skin with methylene chloride can result in burns. Methylene chloride has been found in at least 882 of 1,569 National Priorities List sites identified by the Environmental Protection Agency (EPA).
Disclosed is a process for the preparation of a coated oriented plastic container, which comprises coating an aqueous latex or organic solvent solution of a vinylidene chloride copolymer on at least one surface of a parison, preform or sheet for formation of container which is formed by hot molding of a molecularly orientable thermoplastic resin, drying the coated parison, preform or sheet to form a coating layer, and subjecting the formed coated structure to draw molding such as biaxial draw blow molding or draw forming, wherein the coating layer of the vinylidene chloride copolymer is crystallized at the step of forming the coating layer or the draw molding step. In the coated oriented plastic container prepared according to this process, the adhesion of the coating layer of the vinylidene chloride copolymer to the plastic container substrate is highly improved, and even under severe conditions, peeling of the coating layer is prevented. Moreover, the gas barrier property, strength and chemical
What is 1,1-Dichloroethylene? 1,1-Dichloroethylene (1,1-DCE) is a man-made substance used to make fire retardant fibers and polyethylene food wraps. It is a clear, colorless, flammable liquid with a mild, sweet smell. Dichloroethylene evaporates quickly at room temperature and can pollute the air. When 1,1-DCE gets into water or on soil it evaporates quickly. However, in groundwater or soil, it breaks down very slowly. Most 1,1-DCE in the environment results from industrial use and improper disposal.

BACKGROUND: Diabetes is a major threat to public health in the United States and worldwide. Understanding the role of environmental chemicals in the development or progression of diabetes is an emerging issue in environmental health. OBJECTIVE: We assessed the epidemiologic literature for evidence of associations between persistent organic pollutants (POPs) and type 2 diabetes. METHODS: Using a PubMed search and reference lists from relevant studies or review articles, we identified 72 epidemiological studies that investigated associations of persistent organic pollutants (POPs) with diabetes. We evaluated these studies for consistency, strengths and weaknesses of study design (including power and statistical methods), clinical diagnosis, exposure assessment, study population characteristics, and identification of data gaps and areas for future research. CONCLUSIONS: Heterogeneity of the studies precluded conducting a meta-analysis, but the overall evidence is sufficient for a positive ...

An organochloride, organochlorine compound, chlorocarbon, or chlorinated hydrocarbon is an organic compound containing at least one covalently bonded atom of chlorine that has an effect on the chemical behavior of the molecule. The chloroalkane class (alkanes with one or more hydrogens substituted by chlorine) provides common examples. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names and applications. Organochlorides are very useful compounds in many applications, but some are of profound environmental concern. Chlorination modifies the physical properties of hydrocarbons in several ways. The compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Aliphatic organochlorides are alkylating agents because chloride is a leaving group. Many organochlorine compounds have been isolated from natural sources ranging from bacteria to humans. Chlorinated organic compounds are found in nearly every ...
BACKGROUND: The use of biomarkers of environmental exposure to explore new risk factors for pancreatic cancer presents clinical, logistic, and methodological challenges that are also relevant in research on other complex diseases. OBJECTIVES: First, to summarize the main design features of a prospective case-control study -nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort- on plasma concentrations of persistent organic pollutants (POPs) and pancreatic cancer risk. And second, to assess the main methodological challenges posed by associations among characteristics and habits of study participants, fasting status, time from blood draw to cancer diagnosis, disease progression bias, basis of cancer diagnosis, and plasma concentrations of lipids and POPs. Results from etiologic analyses on POPs and pancreatic cancer risk, and other analyses, will be reported in future articles. METHODS: Study subjects were 1533 participants (513 cases and 1020 controls ...
