organochlorine and heavy metal residues in black duck eggs from the atlantic flyway, 1978.black duck (anas rubripes) eggs were collected during 1978 in the atlantic flyway. one egg from each of 49 clutches was analyzed for organochlorine compounds and mercury. dde was detected in 39 eggs, ranging from 0.09 ppm to 3.4 ppm, wet weight. dde residues were highest in eggs from delaware, where the mean dde level was 2.0 ppm. ddt and tde were present at low levels in only five and four eggs, respectively. pcbs resembling aroclor 1260 were detected in 24 eggs and ranged from 0.43 ppm to 2.9 ...19807232104
