Residues of p,p'-DDE and mercury in lake trout as a function of age
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 less than 0.001) with increasing age of the fish. The concentration of p,p'-DDE also increased significantly (p less than 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.
