Abstract
PCB congeners, DDE, dieldrin and Hg were determined in 21 eggs and a y oung chick from an expanding colony of cormorants in eastern England. Levels of all contaminants were lower than most published values for t his and closely related species, indicating a declining trend in envir onmental concentrations. The most abundant PCB congeners were 153, 138 , 180 and 118. All contaminants were strongly correlated and there wer e significant but weak correlations between egg shell thickness and DD E, dieldrin, total PCB and several PCB congeners.
