title: [Occurrence and health aspects of PCB congeners in freshwater fish].
abstract: 6 PCB-Congeners, being ruled by the regulatory limits from 23. 3. 1988, are considered to be representative under analytical aspects. The additional consideration of the two further congeners 77 and 118 is recommended under toxicological aspects. A widespread survey is given over the pollution status of marine fish, freshwater fish, and belonging to products. In the years between 1986 to 1988 2229 specimens were analysed for their contents of 8 PCB-Congeners and 6 important chlorinated hydrocarbons. Contents in marine fish were at least 10 times, mostly 100 times lower than regulatory limits. In this area contamination is more influenced by species than by catching grounds. Regulatory limits can however be exceeded in freshwater fish from severely polluted main rivers, where contents are more influenced by catching grounds than by species.
