[The enzymatic degradation of DDT. 1. Main degradation pathways]

First investigations on the degradation of DDT were already carried out at the beginning of its application. Its metabolism, however, is not yet absolutely clear till now. Main degradation pathways are considered: Reductive dechlorinations, successive dehydrochlorinations to unsaturated compounds as well as oxidations to aldehydes, alcohol and carboxylic acid. Decarboxylations of carboxylic acids are considered to be dependent on the species concerned. Between various organisms only quantitative differences are evident.
