Tris(4-chlorophenyl)methanol (TCPM) and tris(4-chlorophenyl)methane (TCPMe) are globally widespread contaminants. However, there is a lack of knowledge on production figures, origin, and application of these compounds. One source is technical DDT in which these compounds are present as impurities, but it is assumed that there are other sources as well. Analytical methods for the determination of TCPM...
Polybrominated biphenyls (PBBs) and polybrominated diphenylethers (PBDEs), also called brominated diphenyl oxides, are produced and used as flame retardants. There are theoretically 209 different congeners of both PBBs and PBDEs. These congeners have specific chemical and physical properties, which lead to different biological and toxicological effects. Most studies have been based on commercial mixtures...
Polychlorinated terphenyls (PCTs) have been produced over the same period as polychlorinated biphenyls (PCBs), but in 15-20-fold lower quantities (ca. 60,000 tons in total). The production of PCTs has been terminated in most countries in the mid-1970s. PCTs have similar properties to PCBs and have been used for the same purposes such as in electronic equipment, lubricants, sealants, etc. They are...
