Polychlorinated biphenyls (PCBs) are highly carcinogenic chemical compounds, formerly used in industrial and consumer products, whose production was banned in the United States by the Toxic Substances Control Act in 1979 and internationally by the Stockholm Convention on Persistent Organic Pollutants in … Prikaži več Physical properties The compounds are pale-yellow viscous liquids. They are hydrophobic, with low water solubilities: 0.0027–0.42 ng/L for Aroclors brand, but they have high solubilities in most … Prikaži več One estimate (2006) suggested that 1 million tonnes of PCBs had been produced. 40% of this material was thought to remain in use. Another estimate put the total global production of PCBs on the order of 1.5 million tonnes. The United States was the … Prikaži več PCBs have entered the environment through both use and disposal. The environmental fate of PCBs is complex and global in scale. Water Because of their low vapour pressure, PCBs accumulate … Prikaži več The toxicity of PCBs varies considerably among congeners.
