Organochlorine and heavy metal residues in bald eagle eggs

1970, Pesticides Monitoring Journal (4) 136-140
Bald eagle eggs collected in 1968 from nests in Wisconsin, Maine, and Florida all contained residues of DDE, DDD, dieldrin, heptachlor epoxide, and polychlorinated biphenyls. Many also contained traces of DDT. Eggs from five nonproductive nests sampled in Maine contained much higher residues than did eggs collected from...

1970, Book chapter, Proceedings of the symposium, the biological impact of pesticides in the environment
It has long been known that DDT and related chemicals can impair the reproduction of birds. In early years of organochlorine pesticide use, widespread mortality occurred immediately following heavy applications of these chemicals, and survivors contained substantial amounts of toxicant in their tissues. Repopulation from untreated areas tended...
DDE and DDD residues correlated with mortality of experimental birds

William B. Deichmann, Rafael A. Penalver, Jack L. Radomski, editor(s)
1970, Conference Paper, Pesticides symposia: Collection of papers presented at the 6th -7th Inter-American Conferences on Toxicology and Occupational Medicine, University of Miami School of Medicine, Miami

DDD is also a commercial insecticide. large amounts of both are frequently found in birds, but the significance of these amounts has puzzled many owrkers. Studies at Clear...
A proposed streamflow data program for Ohio
