Polychlorinated biphenyls (PCBs) are organochlorine compounds with the formula C 12 H 10 ... Since the perch is performing more functions in the warmer months, it ...
This is a complete list of polychlorinated biphenyl (PCB) congeners. Chemical structure of PCBs. The possible positions of chlorine atoms on the benzene rings are denoted by numbers assigned to the carbon atoms.
Biphenyl (also known as diphenyl, phenylbenzene, 1,1′-biphenyl, lemonene [4] or BP) is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl .
Polychlorinated biphenyls have been reported to cause a disruption in cellular Ca 2+ homeostasis and translocation of protein kinase C. [10] This disruption is the result of increased ryanodine binding to calcium channels. It is speculated that mechanisms, dependant on the Ah receptor, are involved in neurological changes, but this is not yet ...
Polychlorinated biphenyls (PCBs) are various biphenyl based artificial products that are widely used as a dielectric fluid, industrial coolant, and lubricants in the 1960s and 1970s. There is no evidence its synthesis occurs naturally. They are classified as persistent organic pollutants.
Polychlorinated dibenzofurans (PCDFs), or furans. PCDFs are derivatives of dibenzofuran. There are 135 isomers; 10 have dioxin-like properties. Polychlorinated biphenyls (PCBs), derived from biphenyl, of which 12 are "dioxin-like". Under certain conditions PCBs may form dibenzofurans through partial oxidation.

Polychlorinated biphenyls (PCBs) were once commonly used electrical insulators and heat transfer agents. Their use has generally been phased out due to health concerns. Their use has generally been phased out due to health concerns.
