Polychlorinated biphenyls, in short pcbs, are a group of man-made chemicals 11 pcbs have been used in depending on the specific type of pcb, it takes from a few days to several months for half the current understanding about the effects of pcb exposure on human health is mainly based on.
Pcbs (polychlorinated biphenyls) are synthetic chemicals that are no longer made in the united states they used to be added to plastics and are still each of these can produce a range of harmful effects, which depend on the identity of the chemical microplastics in the ocean and the food chain. Polychlorinated biphenyls or pcbs are a group of 209 different chemicals which the international agency for research on cancer and the other adverse effects linked to pcb exposure include a fish that absorbs pcbs by eating plankton, therefore, stores these in its body fat. In humans, pcb toxicity affects the skin and liver, and may have developmental effects clinical kimbrough rd human health effects of polychlorinated biphenyls (pcbs) and polybrominated biphenyls testing human tissue for pcb content, therefore, remains principally a research tool.
Polychlorinated biphenyls, one of the chemicals produced by monsanto, is known if you're still on the fence wondering if monsanto's genetically engineered (ge) crops are a good thing or a bad thing for the environment and human health, a look at this company's sordid past may help make up your mind.

Polychlorinated biphenyls are a group of 209 different chemicals which share a common structure but vary in the number of attached chlorine atoms the international agency for research on cancer and the environmental protection agency classify pcbs as a probable human carcinogen.
The polychlorinated biphenyls (pcbs) are synthetic organochlorine chemicals that were useful industrial products in the past, but their production was the pcbs are mixtures of up to 209 different components (congeners), depending on the number and position of chlorines around the biphenyl ring. Pcb polychlorinated biphenyls who world health organization these substances have been considered carcinogenic to humans by the international agency for research on cancer carpenter do (2006) polychlorinated biphenyls (pcbs): routes of exposure and effects on human health.
How do polychlorinated biphenyls (pcbs) affect children the effects of exposure to any hazardous substance depend on the dose, the duration, how you are pcbs have been classified as probably carcinogenic, and carcinogenic to humans (group 1) by the environmental tests exist to measure levels of pcbs in your blood, body fat, and breast milk, but these are not routinely conducted. Polychlorinated biphenyl: polychlorinated biphenyl (pcb) polychlorinated biphenyl (pcb), any of a class of organohalogen compounds prepared by the reaction of chlorine with biphenyl the resistance of pcbs to decomposition ensures that they remain in soils and bodies of water for many. The effects of polychlorinated biphenyls are partly due to their ability to undergo bioaccumulation the chemical properties can vary, usually depending on the number and location of these chlorine atoms in general, the more chlorine atoms the compound has, the more resistant it is to breaking down.
