Abstract

Lake trout (Salvelinus namaycush) of known age from 1 to 12 years were taken from Cayuga Lake in central New York State in 1991 and p,p′-DDE and mercury were determined in their flesh. The concentrations of p,p′-DDE and mercury increased significantly (p<0.001) with increasing age of the fish. The concentration of p,p′-DDE also increased significantly (p<0.001) with increasing fat content. The concentrations of p,p′-DDE were much lower than those found in Cayuga Lake trout of similar age captured in 1978.
