PCBs are a mixture of biphenyls with 1 to 10 chlorine atoms (Figure 1). Each variation of this structure is called a congener, and there are a total of 209 congeners. Within any environmental sample ...

Persistent organic pollutants (POPs), particularly polychlorinated biphenyls (PCBs), are synthetic chemicals known for their extreme stability, toxicity, and potential for long-range transport.

Hydroxylated polychlorinated biphenyls (OH-PCBs) are metabolites of PCBs and known endocrine disruptors in humans. Of particular concern regarding this kind of effect has been the disruption of the ...

A variety of biochemical and toxic effects are caused by polychlorinated biphenyls (PCBs) and toxicity varies considerably between animal species. No explanation is available for this variation and ...

We carryied out a meta-analysis of studies on exposure to polychlorinated biphenyls (PCBs) and risk of non-Hodgkin lymphoma (NHL). Through a systematic search of the literature, we identified relative ...

A type of grass that was once a staple of the American prairie can remove soil laden with PCBs, toxic chemicals once used for cooling and other industrial purposes, a study has found. University of ...
