Abstract
It is known for decades that isomeric composition of organic pollutants can be influenced substantially by environmental processes such as biotransformation or transfer between compartments. This accounts also for the pesticide 2,2,-bis(4-chlorophenyl)-1,1,1-trichlorethane, better known as p,p′-DDT, and its accompanied substitution isomer 2-(2-chlorophenyl)-2-(4-chlorophenyl)-1,1,1-trichlorethane (o,p′-DDT). Therefore, for this literature review over 2000 recent literature citations were checked for information on the isomer ratios of DDT and its metabolites in the environment. Although many studies followed the environmental fate of DDT, only very few publications reported on quantitative data of both o,p′- and p,p′-isomers. However, this review revealed evidence for remarkable changes and shifts in o,p′-/p,p′-ratios of DDX. The application of isomer specific analysis remains dominantly on emission source apportionment, e.g. to differentiate DDT and dicofol emission.
