Background: Poly chlorinated biphenyls (PCBS) are the groups of organic chemical material and toxic, persistent, bio accumulate and pose a risk of causing adverse effects to human health and the environment. PCB compounds are caused the different health effects in human depending of age, sex, route of entry, intensity and frequency exposure. This study was conducted to determine the effect of...

background: poly chlorinated biphenyls (pcbs) are a class of chlorinated organic chemicals that do not easily degrade in the environment. this study was conducted to determine the effect of microwave rays, hydrogen peroxide, dioxide titanium and ethanol solvent on the degradation of pcbs. methods: a 900w domestic mw oven with a fixed frequency of 2450 mhz was used to provide mw irradiation. ray...

Polychlorinated biphenyls (PCBs) are accumulated in our body through food chain and cause a variety of adverse health effects including neurotoxicities such as cognitive deficits and motor dysfunction. In particular, neonates are considered as a high risk group for the neurotoxicity of PCBs exposure. The present study attempted to analyze the structure-activity relationship among PCB congeners ...

Polychlorinated biphenyls (PCBs) are widely dispersed in the environment. Occupational exposure to PCBs takes place, e.g., in manufacture and repair of capacitors and transformers. A special type of exposure of workers to PCBs may occur in connection with accidents where capacitors or transformers containing PCBs products are damaged, as in the case of a fire or electric arcing. The quantitatio...

organochlorine contaminants are highly stable and dangerous compounds, which are widespread in the environment. among these compounds, polychlorinated biphenyls (pcbs) are carcinogenic for humans and can also affect intellectual functions and the nervous, immune and reproductive systems. aquatic organism especially fishes are known to be main routes for e entrance of these compounds to the huma...

The aim of this study was to examine the plasma concentrations and prevalence of polychlorinated biphenyls (PCBs) and hydroxylated PCB-metabolites (OH-PCBs) in polar bear (Ursus maritimus) mothers (n=26) and their 4 months old cubs-of-the-year (n=38) from Svalbard to gain insight into the mother-cub transfer, biotransformation and to evaluate the health risk associated with the exposure to thes...
