A comparison of TEQ contributions from PCDDs, PCDFs and dioxin-like PCBs in sewage sludges from Catalonia, Spain.
Eight sewage sludges from rural, urban and industrial wastewater treatment plants (WWTPs) in Catalonia (Spain) were analysed for polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and biphenyls (PCBs) to determine the present levels of contamination. A method based on an automated cleanup system followed by an isotope-dilution high-resolution mass spectrometric analysis was employ...
متن کاملPolychlorinated biphenyls (PCBs)(Arochlors)
Polychlorinated biphenyls (PCBs) are a group of chemicals that contain 209 individual compounds (known as congeners) with varying harmful effects. Information on specific congener toxicity is very limited. Most toxicity testing has been done on specific commercial mixtures; however, PCB mixtures found in the environment will differ in composition from the commercial mixtures because of partitio...
متن کاملCrystal structure and density functional theory studies of toxic quinone metabolites of polychlorinated biphenyls.
Lower chlorinated polychlorinated biphenyls (PCBs) are readily metabolized via hydroxylated metabolites to reactive PCB quinones. Although these PCB metabolites elicit biochemical changes by mechanisms involving cellular target molecules, such as the aryl hydrocarbon receptor, and toxicity by interacting with enzymes like topoisomerases, only few PCB quinones have been synthesized and their con...
متن کاملNano/bio treatment of polychlorinated biphenyls with evaluation of comparative toxicity.
The persistence of polychlorinated biphenyl (PCB) Aroclor 1248 in soils and sediments is a major concern because of its toxicity and presence at high concentrations. In this study, we developed an integrated remediation system for PCBs using chemical catalysis and biodegradation. The dechlorination of Aroclor 1248 was achieved by treatment with bimetallic nanoparticles Pd/nFe under anoxic condi...
متن کاملThe Effect of Polychlorinated Biphenyls on the Song of Two Passerine Species
Polychlorinated biphenyls (PCBs) are synthetic chemical pollutants with demonstrated detrimental toxic and developmental effects on humans and wildlife. Laboratory studies suggest that PCBs influence behavior due to their effects on endocrine and neurological systems, yet little is known about the behavioral consequences of sublethal PCB exposure in the field. Additionally, specific PCB congene...
متن کاملThe public health implications of polychlorinated biphenyls (PCBs) in the environment.
Polychlorinated biphenyls (PCBs) were widely used in various industrial applications. Research confirmed that some PCB congeners degrade slowly in the environment and can build up in the food chain. Poisoning episodes in Asia were initially attributed to PCB-contaminated oil, although subsequent analysis suggested that thermal degradation products of PCBs were responsible for the observed toxic...
