Dioxin-Like and Non-Dioxin-Like Toxic Effects of Polychlorinated Biphenyls (PCBs): Implications For Risk Assessment

Critical Reviews in Toxicology, 1998
(Uploaded by Plazi for the Bat Literature Project) Polychlorinated biphenyls (PCBs) are persistent, bioaccumulative, and toxic contaminants in the environment. Individual PCB congeners exhibit different physicochemical properties and biological activities that result in different environmental distributions and toxicity profiles.

Polychlorinated biphenyls and breast cancer: evidence, mechanisms, and risk management [PDF]

Frontiers in Cell and Developmental Biology
Epidemiological inconsistencies currently obscure the causal link between polychlorinated biphenyls (PCBs) and breast cancer. This review synthesizes multi-disciplinary evidence to characterize PCBs not as passive exposure correlates but as active ...
