Decolorization and detoxification of extraction-stage effluent from chlorine bleaching of kraft pulp by Rhizopus oryzae. (1/308)

Rhizopus oryzae, a zygomycete, was found to decolorize, dechlorinate, and detoxify bleach plant effluent at lower cosubstrate concentrations than the basidiomycetes previously investigated. With glucose at 1 g/liter, this fungus removed 92 to 95% of the color, 50% of the chemical oxygen demand, 72% of the adsorbable organic halide, and 37% of the extractable organic halide in 24 h at temperatures of 25 to 45 degrees C and a pH of 3 to 5. Even without added cosubstrate the fungus removed up to 78% of the color. Monomeric chlorinated aromatic compounds were removed almost completely, and toxicity to zebra fish was eliminated. The fungal mycelium could be immobilized in polyurethane foam and used repeatedly to treat batches of effluent. The residue after treatment was not further improved by exposure to fresh R. oryzae mycelium.  (+info)

Initial reactions in the biodegradation of 1-chloro-4-nitrobenzene by a newly isolated bacterium, strain LW1. (2/308)

Bacterial strain LW1, which belongs to the family Comamonadaceae, utilizes 1-chloro-4-nitrobenzene (1C4NB) as a sole source of carbon, nitrogen, and energy. Suspensions of 1C4NB-grown cells removed 1C4NB from culture fluids, and there was a concomitant release of ammonia and chloride. Under anaerobic conditions LW1 transformed 1C4NB into a product which was identified as 2-amino-5-chlorophenol by 1H and 13C nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry. This transformation indicated that there was partial reduction of the nitro group to the hydroxylamino substituent, followed by Bamberger rearrangement. In the presence of oxygen but in the absence of NAD, fast transformation of 2-amino-5-chlorophenol into a transiently stable yellow product was observed with resting cells and cell extracts. This compound exhibited an absorption maximum at 395 nm and was further converted to a dead-end product with maxima at 226 and 272 nm. The compound formed was subsequently identified by 1H and 13C NMR spectroscopy and mass spectrometry as 5-chloropicolinic acid. In contrast, when NAD was added in the presence of oxygen, only minor amounts of 5-chloropicolinic acid were formed, and a new product, which exhibited an absorption maximum at 306 nm, accumulated.  (+info)

Superficial buffer barrier and preferentially directed release of Ca2+ in canine airway smooth muscle. (3/308)

We examined cytosolic concentration of Ca2+ ([Ca2+]i) in canine airway smooth muscle using fura 2 fluorimetry (global changes in [Ca2+]i), membrane currents (subsarcolemmal [Ca2+]i), and contractions (deep cytosolic [Ca2+]i). Acetylcholine (10(-4) M) elicited fluorimetric, electrophysiological, and mechanical responses. Caffeine (5 mM), ryanodine (0.1-30 microM), and 4-chloro-3-ethylphenol (0.1-0.3 mM), all of which trigger Ca2+-induced Ca2+ release, evoked Ca2+ transients and membrane currents but not contractions. The sarcoplasmic reticulum (SR) Ca2+-pump inhibitor cyclopiazonic acid (CPA; 10 microM) evoked Ca2+ transients and contractions but not membrane currents. Caffeine occluded the response to CPA, whereas CPA occluded the response to acetylcholine. Finally, KCl contractions were augmented by CPA, ryanodine, or saturation of the SR and reduced when SR filling state was decreased before exposure to KCl. We conclude that 1) the SR forms a superficial buffer barrier dividing the cytosol into functionally distinct compartments in which [Ca2+]i is regulated independently; 2) Ca2+-induced Ca2+ release is preferentially directed toward the sarcolemma; and 3) there is no evidence for multiple, pharmacologically distinct Ca2+ pools.  (+info)

Earthworm egg capsules as vectors for the environmental introduction of biodegradative bacteria. (4/308)

Earthworm egg capsules (cocoons) may acquire bacteria from the environment in which they are produced. We found that Ralstonia eutropha (pJP4) can be recovered from Eisenia fetida cocoons formed in soil inoculated with this bacterium. Plasmid pJP4 contains the genes necessary for 2,4-dichlorophenoxyacetic acid (2,4-D) and 2, 4-dichlorophenol (2,4-DCP) degradation. In this study we determined that the presence of R. eutropha (pJP4) within the developing earthworm cocoon can influence the degradation and toxicity of 2,4-D and 2,4-DCP, respectively. The addition of cocoons containing R. eutropha (pJP4) at either low or high densities (10(2) or 10(5) CFU per cocoon, respectively) initiated degradation of 2,4-D in nonsterile soil microcosms. Loss of 2,4-D was observed within the first week of incubation, and respiking the soil with 2,4-D showed depletion within 24 h. Microbial analysis of the soil revealed the presence of approximately 10(4) CFU R. eutropha (pJP4) g-1 of soil. The toxicity of 2,4-DCP to developing earthworms was tested by using cocoons with or without R. eutropha (pJP4). Results showed that cocoons containing R. eutropha (pJP4) were able to tolerate higher levels of 2,4-DCP. Our results indicate that the biodegradation of 2, 4-DCP by R. eutropha (pJP4) within the cocoons may be the mechanism contributing to toxicity reduction. These results suggest that the microbiota may influence the survival of developing earthworms exposed to toxic chemicals. In addition, cocoons can be used as inoculants for the introduction into the environment of beneficial bacteria, such as strains with biodegradative capabilities.  (+info)

Heat-induced expression and chemically induced expression of the Escherichia coli stress protein HtpG are affected by the growth environment. (5/308)

Differences in expression of the Escherichia coli stress protein HtpG were found following exposure of exponentially growing cells to heat or chemical shock when cells were grown under different environmental conditions. With an htpG::lacZ reporter system, htpG expression increased in cells grown in a complex medium (Luria-Bertani [LB] broth) following a temperature shock at 45 degrees C. In contrast, no HtpG overexpression was detected in cells grown in a glucose minimal medium, despite a decrease in the growth rate. Similarly, in pyruvate-grown cells there was no heat shock induction of HtpG expression, eliminating the possibility that repression of HtpG in glucose-grown E. coli was due to catabolite repression. When 5 mM phenol was used as a chemical stress agent for cells growing in LB broth, expression of HtpG increased. However, when LB-grown cells were subjected to stress with 10 mM phenol and when both 5 and 10 mM phenol were added to glucose-grown cultures, repression of htpG expression was observed. 2-Chlorophenol stress resulted in overexpression of HtpG when cells were grown in complex medium but repression of HtpG synthesis when cells were grown in glucose. No induction of htpG expression was seen with 2, 4-dichlorophenol in cells grown with either complex medium or glucose. The results suggest that, when a large pool of amino acids and proteins is available, as in complex medium, a much stronger stress response is observed. In contrast, when cells are grown in a simple glucose mineral medium, htpG expression either is unaffected or is even repressed by imposition of a stress condition. The results demonstrate the importance of considering differences in growth environment in order to better understand the nature of the response to an imposed stress condition.  (+info)

Fraction of electrons consumed in electron acceptor reduction and hydrogen thresholds as indicators of halorespiratory physiology. (6/308)

Measurements of the hydrogen consumption threshold and the tracking of electrons transferred to the chlorinated electron acceptor (f(e)) reliably detected chlororespiratory physiology in both mixed cultures and pure cultures capable of using tetrachloroethene, cis-1, 2-dichloroethene, vinyl chloride, 2-chlorophenol, 3-chlorobenzoate, 3-chloro-4-hydroxybenzoate, or 1,2-dichloropropane as an electron acceptor. Hydrogen was consumed to significantly lower threshold concentrations of less than 0.4 ppmv compared with the values obtained for the same cultures without a chlorinated compound as an electron acceptor. The f(e) values ranged from 0.63 to 0.7, values which are in good agreement with theoretical calculations based on the thermodynamics of reductive dechlorination as the terminal electron-accepting process. In contrast, a mixed methanogenic culture that cometabolized 3-chlorophenol exhibited a significantly lower f(e) value, 0.012.  (+info)

Biodegradation of pentachlorophenol in a continuous anaerobic reactor augmented with Desulfitobacterium frappieri PCP-1. (7/308)

In this work, a strain of anaerobic pentachlorophenol (PCP) degrader, Desulfitobacterium frappieri PCP-1, was used to augment a mixed bacterial community of an anaerobic upflow sludge bed reactor degrading PCP. To estimate the efficiency of augmentation, the population of PCP-1 in the reactor was enumerated by a competitive PCR technique. The PCP-1 strain appeared to compete well with other microorganisms of the mixed bacterial community, with its population increasing from 10(6) to 10(10) cells/g of volatile suspended solids within a period of 70 days. Proliferation of strain PCP-1 allowed for a substantial increase of the volumetric PCP load from 5 to 80 mg/liter of reaction volume/day. A PCP removal efficiency of 99% and a dechlorination efficiency of not less than 90.5% were observed throughout the experiment, with 3-Cl-phenol and phenol being observable dechlorination intermediates.  (+info)

Reductive dehalogenation and conversion of 2-chlorophenol to 3-chlorobenzoate in a methanogenic sediment community: implications for predicting the environmental fate of chlorinated pollutants. (8/308)

Biotransformation of 2-chlorophenol by a methanogenic sediment community resulted in the transient accumulation of phenol and benzoate. 3-Chlorobenzoate was a more persistent product of 2-chlorophenol metabolism. The anaerobic biotransformation of phenol to benzoate presumably occurred via para-carboxylation and dehydroxylation reactions, which may also explain the observed conversion of 2-chlorophenol to 3-chlorobenzoate.  (+info)

Removal of phenol and chlorophenols from water with reusable dye-affinity hollow fibers | AVESİSRemoval of phenol and chlorophenols from water with reusable dye-affinity hollow fibers | AVESİS
Reactive Green HE 4BD carrying polyamide hollow fibers were investigated as dye-affinity adsorbents for removal of chlorophenols (i.e., phenol. o-chlorophenol, p-chlorophenol and 2,4,6-trichlorophenol). Adsorption rates of chlorophenols were very high. Equilibrium was achieved in about 30 min. The applicability of two kinetic models including pseudo-first order and pseudo-second order model was estimated on the basis of comparative analysis of the corresponding rate parameters, equilibrium capacity and correlation coefficients. Results suggest that chemisorption process could be the rate-limiting step in the adsorption process. The maximum adsorption values of chlorophenols onto the Reactive Green HE 4BD carrying hollow fibers were 145.9 mu mol/g for phenol, 179.2 mu mol/g for 2,4,6-trichlorophenol, 194.5 mu mol/g for p-chlorophenol and 202.8 mu mol/g for o-chlorophenol. The affinity order was as follows: o-chlorophenol > p-chlorophenol > 2,4,6-trichlorophenol > phenol. The adsorption capacity ...

Determination of trace chlorophenols (CPs) in environmental samples has been evaluated using liquid-phase microextraction (LPME) coupled with gas chromatography-mass spectrometry (GC-MS) without derivatization. The LPME procedure used to extract CPs from water involved 15 mu l 1-octanol as acceptor solution in a 5.0 cm polypropylene hollow fiber with an inner diameter of 600 mu m and a pore size of 0.2 mu m. Under the optimal extraction conditions, enrichment factors from 117 to 220 are obtained. The obtained linear range is 1-100 ngmL(-1) with r(2) =0.9967 for 2,4-dichlorophenol (2,4-130); 1-100 ngmL(-1) with r(2) =0.9905 for 2,4,6-trichlorophenol (2,4,6-TCP); 5-500 ngmL(-1) with r(2) = 0.9983 for 2,3,4,6-tetrachlorophenol (2,3,4,6-TeCP), and 10-1000ngmL(-1) with r(2)=0.9929 for pentachlorophenol (PCP). The limits of detection range from 0.08 to 2 ngmL(-1), which is comparable with the reported values (12-120 ngmL(-1)). Recoveries of CPs in various matrices exceed 85% with relative standard ...

Toxicity assessment of chlorophenols using a mediated microbial toxicity assayToxicity assessment of chlorophenols using a mediated microbial toxicity assay
While direct toxicity assessment (DTA) is now widely recognised as a useful tool for environmental risk assessment, many existing tests fail to meet end-user needs. This article describes the significant progress made to the MICREDOX® DTA assay, developed at Lincoln Ventures Ltd, brought about by miniaturising this assay to a multi-well plate format combined with limiting current microelectrode transduction. The benefits have been reduced: preparation time, reduced assay time, lower material costs and a higher level of replication achieved. To validate the precision of the miniaturised format, the concentrations required to cause a 50% decrease in signal (EC50) by an archetypal group of toxicants, the chlorophenols, were determined using two terrestrial bacterial strains, Escherichia coli K12 and Klebsiella oxytoca 13183. The assay time was then reduced by stepwise adjustment of the incubation time, from 60 down to 5 min, and the EC50s reported by E. coli to each of the toxicants after 45, 30, ...

Abstract : 2,4-Dichlorophenol (2,4-DCP) and 2,6-dichlorophenol (2,6-DCP) are two isomers of dichlorophenols, have beenused as preservative agents for wood, paints, vegetable fibers and as intermediates in the production of pharmaceuticals anddyes. The aim of the study was to evaluate the impact of biofield energy treatment on the isotopic abundance ratios of 2H/1H or13C/12C, and 18O/16O or 37Cl/35Cl, in dichlorophenol isomers using gas chromatography-mass spectrometry (GC-MS). The 2,4-DCP and 2,6-DCP samples were divided into two parts: control and treated. The control sample remained as untreated, whilethe treated sample was further divided into four groups as T1, T2, T3, and T4. The treated group was subjected to Mr. Trivedisbiofield energy treatment. The GC-MS spectra of 2,4-DCP and 2,6-DCP showed three to six m/z peaks at 162, 126, 98, 73, 63,37 etc. due to the molecular ion peak and fragmented peaks. The isotopic abundance ratios (percentage) in both the isomerswere increased significantly ...

Bioremediation of low-permeability, pentachlorophenol-contaminated soil by laboratory and full-scale processes
Ex-situ bioremediation of saturated soil contaminated with pentachlorophenol and 2,3,5,6-TeCP is commonly accomplished by landfarming or by treatment in a bioreactor. Treating saturated, low-permeability soils in bioreactors, without pre-treatment requires a reactor capable of promoting anaerobic and/or aerobic removal of chlorophenols without transferring these contaminants to the aqueous phase. A pilot-scale bioreactor was designed to treat 3.7 cubic meters of contaminated soil with a saturated hydraulic conductivity of 0.12 cm/day. The bioreactor demonstrated significant removal of chlorophenols when soil was infused with a treatment mixture containing imitation vanilla flavoring as an electron donor for reductive dechlorination and primary substrate for aerobic cometabolism. Bench scale studies showed greater overall removal when feed mixtures included an inoculated biomass, or when treatment mixtures were maintained anaerobically prior to use. The combined results of these studies suggest ...

The residue dynamics and risk assessment of prochloraz and its metabolite 2,4,6-trichlorophenol (2,4,6-TCP) in apple under different treatment concentrations were investigated using a GC-ECD method. The derivatization percent of prochloraz to 2,4,6-TCP was stable and complete. The recoveries of prochloraz and 2,4,6-TCP were 82.9%-114.4%, and the coefficients of variation (CV) were 0.7%-8.6% for the whole fruit, apple pulp, and apple peel samples. Under the application of 2 °C 2.0 g/L, 2 °C 1.0 g/L, 20 °C 2.0 g/L, and 20 °C 1.0 g/L treatment, the half-life for the degradation of prochloraz was 57.8-86.6 d in the whole fruit and apple peel, and the prochloraz concentration in the apple pulp increased gradually until a peak (0.72 mg·kg−1) was reached. The concentration of 2,4,6-TCP was below 0.1 mg·kg−1 in four treatment conditions and not detected (<LOD) in apple pulp. Finally, based on the detection of market samples in Hefei (China), we believe that the residual level of prochloraz in

The unexplained deaths and illnesses at Shenandoah immediately caught the attention of the Centers for Disease Control (CDC). In August 1971, the CDC completed an inspection of Shenandoah Stable, and collected human and animal blood samples, as well as soil samples.[10] Although initial results revealed that the soil at Shenandoah Stable contained PCBs and chlorinated insecticides, the CDC was unable to identify a specific chemical culprit. It was not until 1973 that tests revealed the presence of trichlorophenol.[14] When trace amounts of the crude trichlorophenol contaminant were administered to the inner surfaces of rabbit ears, blisters developed, which was a characteristic result of trichlorophenol poisoning.[10] The unexpected death of some of the affected rabbits however, led the CDC to run more complex tests. On July 30, 1974, the CDC found that, in addition to 5,000 ppm of trichlorophenol and 1,590 ppm of PCBs, the soil samples collected from Shenandoah contained over 30 ppm of ...

at correlate with those reported by other recognised DTA and BOD methods. The miniaturised MICREDOX® DTA assay reported EC₅₀ (concentration where effect is 50%) values that were in close accord to those previously reported with other recognised methodology for a group of chlorophenols (4-chlorophenol, 2,4-dichlorophenol, 3,5- dichlorophenol and pentachlorophenol). Good correlation indices indicated that the miniaturised assay was capable of determining reproducible EC₅₀ values. The ability for this assay to report EC₅₀ values for other groups of toxicants, however, was shown to be limited due to the mediator potassium hexacyanoferrate III (HCF). Use of alternative redox mediators (hexamine ruthenium chloride II, methylene blue, neutral red, phenazine ethosulfate, resazurin, toluidine blue-O and TIRON® showed that those chosen could not report accurate bacterial respiration, and were therefore unable to be utilised as a reliable primary mediator in the MICREDOX® assay.

Degradation of chlorophenol mixtures in a fed-batch system by two soil bacteriaDegradation of chlorophenol mixtures in a fed-batch system by two soil bacteria
This parameter is a very useful tool that involves the degradation rate and the biomass growth, referred to the initial biomass instead of the actual biomass. Progressively, the biomass grows and the degradation rate increases. This parameter simultaneously takes both into account.. Results and discussion. The mixed culture constituted of Pseudomonas aeruginosa and Achromobacter marplatensis was able to simultaneously degrade the mixture of highly-substituted chlorophenols PCP, 2,3,5,6-TeCP and 2,4,6-TCP, as the only source of carbon and energy in batch and fed-batch systems. The initial experimental settings for the fed-batch assays at different feed flow rates (I, II, III) and the batch system control (B) is shown in Table 1. The initial biomass was similar in all cases but the initial CP concentrations were much higher in B than in the fed-batch assays when they were close to zero (Table I). The substrate to biomass yield coefficients based on total CP degradation are also shown in Table 1. ...

2,4,5-TCP 4-monooxygenase (TftD) and 2,4,6-TCP 4-monooxygenase (TcpA) have been discovered in the biodegradation of 2,4,5-trichlorophenol (2,4,5-TCP) and 2,4,6-trichlorophenol (2,4,6-TCP). TcpA and TftD belong to the reduced flavin adenine dinucleotide (FADH2)-dependent monooxygenases and both use 2,4,6-TCP as a substrate; however, the two enzymes produce different end products. TftD catalyzes a typical monooxygenase reaction, while TcpA catalyzes a typical monooxygenase reaction followed by a hydrolytic dechlorination. We have previously reported the 3D structure of TftD and confirmed the catalytic residue, His289. Here we have determined the crystal structure of TcpA and investigated the apparent differences in specificity and catalysis between these two closely related monooxygenases through structural comparison. Our computational docking results suggest that Ala293 in TcpA (Ile292 in TftD) is possibly responsible for the differences in substrate specificity between the two monooxygenases. We have

Peer Evaluation : Studies on Physicochemical Properties of Biofield Treated 2,4-Dichlorophenol
Abstract : The chlorinated phenols are widely used in chemical industries for the manufacturing of herbicides, insecticides,etc. However, due to consistent use they create hazards to the environment. This study was designed to use an alternativemethod i.e. biofield energy treatment and analyse its impact on the physicochemical properties of 2,4-dichlorophenol (2,4-DCP), which are the important factors related to its degradation. The 2,4-DCP sample was treated with Mr. Trivedis biofieldenergy and analyzed as compared to the untreated 2,4-DCP sample (control) using various analytical techniques. The X-raydiffraction studies revealed up to 19.4% alteration in the lattice parameters along with approximately 1.8% alteration in themolecular weight, unit cell volume and density of the treated sample. The crystallite size of treated sample was increased andfound as 215.24 nm as compared to 84.08 nm in the control sample. Besides, the thermal study results showed an alteration inthe thermal stability ...

Research on substituted phenol degradations has received substantial attention. In this work, effective Co(II) and Cu(II) phthalocyanine complexes as catalysts were studied to degrade toxic phenols to harmless products. The effect of various process parameters, such as initial concentration of phenol, catalyst, oxygen sources, and temperature on the degradation reaction was investigated to achieve maximum degradation efficiency. The catalytic activities of Co(II) and Cu(II) phthalocyanines were evaluated for oxidation of phenolic compounds such as p-nitrophenol, o-chlorophenol, 2,3-dichlorophenol, and m-methoxyphenol. Co(II) phthalocyanine displayed good catalytic performance in degradation of 2,3-dichlorophenol to 2,3-dichlorobenzaldehyde and 2,3-dichloro-1,4-benzoquinone with the highest TON and TOF values within 3h at 50 degrees C. The fate of catalyst during the degradation process was followed by UV-Vis spectroscopy. ...

While direct toxicity assessment (DTA) is now widely recognised as a useful tool for environmental risk assessment, many existing tests fail to meet end-user needs. This article describes the significant progress made to the MICREDOX® DTA assay, developed at Lincoln Ventures Ltd, brought about by miniaturising this assay to a multi-well plate format combined with limiting current microelectrode transduction. The benefits have been reduced: preparation time, reduced assay time, lower material costs and a higher level of replication achieved. To validate the precision of the miniaturised format, the concentrations required to cause a 50% decrease in signal (EC50) by an archetypal group of toxicants, the chlorophenols, were determined using two terrestrial bacterial strains, Escherichia coli K12 and Klebsiella oxytoca 13183. The assay time was then reduced by stepwise adjustment of the incubation time, from 60 down to 5 min, and the EC50s reported by E. coli to each of the toxicants after 45, 30, ...

The Effect of Bulky Substituents on the Formation of Symmetrically Trisubstituted Triptycenes
A series of 1,8-dichloroanthracene precursor molecules with substituents in C-10 position of different steric demand (cyclohexyl, tert-butyl, methyl, isopropyl, n-butyl, phenyl, benzyl, trimethylsilylethinyl) were synthesised and subjected to electrocyclic cycloadditions with chlorobenzyne generated from 3-chloroanthranilic acid. The aim was to steer the regioselectivity of the addition reaction by the steric repulsion between this C-10 substituent and the chlorine substituent at the benzyne intermediate. With H as C-10 substituent the reaction leads to 23% syn and 77% anti form. With the small methyl group a syn/anti ratio of 37:63 was achieved. Contrary to our expectations the large C-10 substituent tert-butyl leads to 100% selectivity for the anti form. The best results were achieved for the C-10 substituent n-butyl with a syn/anti ratio of 40:60. The crystal structures of five 1,8-dichloroanthracenes with C-10 substituents were determined, namely those with tert-butyl, cyclohexyl, n-butyl ...

An interlaboratory study was organised to validate the preliminary CEN method PrEN 12673: Water Quality - Gas Chromatographic determination of some selected chlorophenols in water. This intercomparison study on three types of water - drinking water, surface water and waste water - comprised a total of nine samples: a high-level, low-level and blank for each of the three types of water. The level of sample was based on the water quality objectives. The variation of the samples with respect to homogeneity and stability of the components appeared after extensive testing to be negligible in comparison with the variation between the results of the participants. In this data set about 7% of the data were detected as statistical outliers and subsequently rejected. For the remaining data set the relative standard deviations for repeatability varied between 5% and 25% and reproducibility between 25% and 55%. Both these ranges comply with the general variation in interlaboratory studies as found by ...

Transcripts of cprA5 were not detected from strain PCP-1 cultured in the absence of CPs, but they were detected in the presence of 2,4,6-TCP or 3,5-DCP (an inducer of the meta- and para-dechlorinating activities) [40]. RT-qPCR revealed that cprA5 expression was strongly upregulated in the presence of 3,5-DCP in strain PCP-1 cultures [50]. For 2,4,6-TCP-amended cultures, the occurrence of 2,4-DCP was associated with the upregulation of cprA5 in strain PCP-1 cultures. Kim et al. [38] also observed this upregulation with the D. hafniense strain DCB-2 for rdhA3 (corresponding to cprA5) by microarrays. Upregulation of cprA5 occurred in cultures containing as little as 0.15 µM 3,5-DCP [50]. No upregulation was observed in PCP-amended cultures after 12 h (figure 4).. Significant upregulation of cprA4 was not observed in strain PCP-1 cultures amended with 2,4,6-TCP or 3,5-DCP. However, in PCP-amended cultures, we noticed a 13-fold increase in cprA4 transcript levels, which was just above the level of ...

Soft-tissue sarcoma - WikipediaSoft-tissue sarcoma - Wikipedia
A soft-tissue sarcoma is a form of sarcoma that develops in connective tissue, though the term is sometimes applied to elements of the soft tissue that are not currently considered connective tissue. In their early stages, soft-tissue sarcomas usually do not cause symptoms. Because soft tissue is relatively elastic, tumors can grow rather large, pushing aside normal tissue, before they are felt or cause any problems. The first noticeable symptom is usually a painless lump or swelling. As the tumor grows, it may cause other symptoms, such as pain or soreness, as it presses against nearby nerves and muscles. If in the abdomen it can cause abdominal pains commonly mistaken for menstrual cramps, indigestion, or cause constipation.[citation needed] Most soft-tissue sarcomas are not associated with any known risk factors or identifiable cause. There are some exceptions: Studies suggest that workers who are exposed to chlorophenols in wood preservatives and phenoxy herbicides may have an increased risk ...

Estimating the effect of burrowing shrimp on deep-sea sediment community oxygen consumption (detailed view)Estimating the effect of burrowing shrimp on deep-sea sediment community oxygen consumption (detailed view)
Sediment community oxygen consumption (SCOC) is a proxy for organic matter processing and thus provides a useful proxy of benthic ecosystem function. Oxygen uptake in deep-sea sediments is mainly driven by bacteria, and the direct contribution of benthic macro- and mega-infauna respiration is thought to be relatively modest. However, the main contribution of infaunal organisms to benthic respiration, particularly large burrowing organisms, is likely to be indirect and mainly driven by processes such as feeding and bioturbation that stimulate bacterial metabolism and promote the chemical oxidation of reduced solutes. Here, we estimate the direct and indirect contributions of burrowing shrimp (Eucalastacus cf. torbeni) to sediment community oxygen consumption based on incubations of sediment cores from 490 m depth on the continental slope of New Zealand. Results indicate that the presence of one shrimp in the sediment is responsible for an oxygen uptake rate of about 40 µmol d−1, only 1% of ...

Free radical-triggered tissue damage is believed to play an essential role in a variety of human diseases. Pentachlorophenol (PCP) is applied as a pesticide worldwide in both industries and homes. It is used extensively as a biocide and wood preservative. Tetrachlorohydroquinone (TCHQ) was proved as a major toxic metabolite of PCP, contributing the release of free radicals during PCP metabolism. PCP has been proposed as a tumor promoter; however, only limited knowledge is available regarding the mechanisms of tumor promotion induced by PCP and its metabolite, TCHQ. A growing amount of literature suggests that a link between reactive oxygen species (ROS) and tumor promotion could exist. Herein, we summarize the findings regarding the ROS-triggered signaling pathways involved in the cytotoxicity and tumor promotion effects of PCP and TCHQ. Some of the notable findings demonstrated that TCHQ can induce DNA lesions and glutathione depletion in mammalian cells; meanwhile, oxidative stress and apoptosis

The trans-continental distributions of pentachlorophenol and pentachloroanisole in pine needles indicate separate originsThe trans-continental distributions of pentachlorophenol and pentachloroanisole in pine needles indicate separate origins
The production and use of pentachlorophenol (PCP) was recently prohibited/restricted by the Stockholm Convention on persistent organic pollutants (POPs), but environmental data are few and of varying quality. We here present the first extensive dataset of the continent-wide (Eurasia and Canada) occurrence of PCP and its methylation product pentachloroanisole (PCA) in the environment, specifically in pine needles. The highest concentrations of PCP were found close to expected point sources, while PCA chiefly shows a northern and/or coastal distribution not correlating with PCP distribution. Although long-range transport and environmental methylation of PCP or formation from other precursors cannot be excluded, the distribution patterns suggest that such processes may not be the only source of PCA to remote regions and unknown sources should be sought. We suggest that natural sources, e.g., chlorination of organic matter in Boreal forest soils enhanced by chloride deposition from marine sources, ...

Method Aerobic wastewater microorganisms of activated sludge exposed to test substance in a 3 -hour respiration inhibition test according to OECD guideline 209. Nominal tested concentrations were: 10, 32, 100, 320 and 1000 mg/l. Concentrations in excess of nominal 1000 mg/l were not tested. In addition, 2 controls and 3 different concentrations of the reference item 3,5-dichlorophenol (5, 16 and 50 mg/l) were tested in parallel. Results The results of these treatments confirmed suitability of the activated sludge and the method used. Up to and including the highest concentration of nominal 1000 mg/l, test substance had no significant inhibitory effect (, 15 %) on the respiration rate of activated sludge after the incubation period of 3 hours. Based on the physical appearance of test suspensions, the saturation concentration (equilibrium) under present test conditions was reached and resulted in less than 15 % inhibition after 3 hours contact time. Thus, the 3-hour EC50 is clearly higher than the ...
