Abstract
Due to a lack of information on residues of chlorinated com- pounds in fish from Connecticut lakes and ponds, we conducted a preliminary assessment of total chlordane, total DDT, and total PCBs in fish tissue. Preda- tors (largemouth bass and smallmouth bass) and bottom feeders (common carp, brown bullhead, yellow bullhead, and white sucker) were collected from 16 Connecticut lakes in 1998. Fish tissue samples consisted of a composite of one skin-on fillet from up to three individual fish representing one species. Fish were analyzed for chlorinated compounds by a gas chromatography/electron capture detector. Fish from seven lakes had detectable levels of chlordane. One lake had fish with chlordane residue levels exceeding the Food and Drug Administration action level of 300 micrograms per kilogram (gg/kg) wet weight. At all 16 sites, p,p'-DDE was detected in fish tissue. At seven sites, PCBs, primarily Aroclor-1254, were detected in fish tissue; the highest concen- tration reported was 2344 gg/kg wet weight.
