Polychlorinated biphenyls, in short PCBs, are a group of man-made chemicals. Polychlorinated biphenyls (PCBs) are a group of chemicals that have extremely high boiling points and are practically nonflammable. In the Lind et al. 19 For a number of years, chloracne of the face and neck has been reported among workers exposed to chlorinated hydrocarbons. The known toxic effects of PCBs in humans include an acnelike skin eruption (chloracne), pigmentation of the skin and nails, excessive eye discharge, swelling of eyelids, and distinctive hair follicles. 1 Evidence of their negative impact on human health emerged very early in their industrial-scale production, 2 and studies published in the 1960s confirmed that PCB contamination was widespread and persistent in both the environment and people's bodies. They pose serious health risks to fetuses, babies and children, who may suffer developmental and neurological problems from prolonged or repeated exposure to small amounts of PCBs. Health effects and exposure to polychlorinated biphenyls (PCBs) and metals in a contaminated community. Hormonal deficits in humans can lead to many health conditions, though research is currently underway to directly link PCBs to such disruptions.

This public health statement tells you about polychlorinated biphenyls (PCBs) and the effects of exposure. Polychlorinated biphenyls, or PCBs, are a group of 209 structurally related chemical compounds (congeners), consisting of two connected benzene rings and 1-10 chlorine atoms ().They were once used in industrial applications, particularly as electrical insulating fluids and as heat-exchange fluids, until concern over possible adverse effects on the environment and on human health resulted in . The purpose of this health consultation is to identify and prevent harmful human health effects resulting from exposure to hazardous substances in the environment. Koopman-Esseboom C, et al.

PCBs were manufactured domestically from 1929 until . Exposure to polychlorinated biphenyls (PCBs) is associated with depressive symptomatology. PCBs have no known smell or taste. Although PCBs have not been used commercially since about 1977 in the US, they can still be detected in human blood and tissues in this country. In the human body, PCBs can remain in fatty tissues and in the liver and may be transferred from mother to child through the placenta or breast milk. Polychlorinated biphenyls (PCBs) are a group of human-made chemicals that were commonly used in building materials and electrical equipment before 1980.

Polychlorinated biphenyls, or PCBs, belong to a broad family of human-made organic chemicals known as chlorinated hydrocarbons.PCBs were manufactured worldwide from 1929 until the United States banned their manufacture in 1979. Some studies on the health effects of PCBs are confounded by exposure to other halogenated environmental contaminants and by impurities in the PCBs . Little is known about the health impacts that result from long-term exposure to low concentrations of PCBs. The polychlorinated biphenyls (PCBs) are synthetic organochlorine chemicals that were useful industrial products in the past, but their production was ended because they persist in both the environment and living organisms.
