Certain former operations in capacitor manufacturing resulted in extensive direct contact of the workers with electrical grade polychlorinated biphenyls (PCBs). A study group of 194 such individuals, all exposed to Aroclor 1016 and many previously exposed to Aroclors 1242 and/or 1254, was examined b …
Role of Metabolism in TCE Toxicity. A broad and complex range of relevant information for assessing human health effects of TCE is available. Previous reviews have found TCE to adversely affect the central nervous system (Bale et al. 2011), liver (), kidney (Lash et al. 2000b), immune system (Cooper et al. 2009), and reproductive systems and …
Explore the various health effects associated with PCB exposure, from neurological and developmental issues to cancer risks, shedding light on the potential consequences for affected individuals. …
Exposure to PCBs suppresses the immune system, thereby increasing the risk of acquiring several human diseases. Both ortho-substituted and coplanar (dioxin-like) congeners are tumor promoters that enhance the effects of other carcinogenic substances. PCB exposure, especially during fetal and early life, reduces IQ and alters behavior.
PCB Exposure Health Effects and Risks. Polychlorinated biphenyls (PCBs) are a group of synthetic organic chemicals that, for decades, found their way into countless industrial applications due to their insulation and fire-resistant properties.
Exposure to these low levels does not appear to affect human health. However, PCBs can accumulate in the human body and remain there for years. ...

Introduction: Polychlorinated biphenyls (PCBs) are persistent, lipophilic contaminants that are known to increase risk of a number of human diseases. Although ingestion of animal fats is a major route of exposure, there is increasing evidence that inhalation of vapor-phase PCBs is also important and may be as or even more important than ingestion …
