1971, Pesticides Monitoring Journal (5) 248-250
Woodcock (Philohela minor), earthworms, and soil samples were collected from January-March 1965, from fields in southeastern Louisiana approximately 3 years after discontinuance of areal treatments with heptachlor in this region. Heptachlor epoxide residues in woodcock averaged 0.42 ppm (dry weight), conspicuously lower than in 1961 and 1962. Residues...
Semiquantitative determination of polychlorinated biphenyls in tissue samples by thin layer chromatography

1971, Journal of the Association of Official Analytical Chemists (54) 548-550
A method is described for the analysis of polychlorinated biphenyl (PCB) compounds in tissue samples. Cleanup by hexane-acetonitrile partitioning and Florisil column chromatography are performed on samples before oxidative treatment to convert DDE to DCBP. PCB components are then determined semi-quantitatively by TLC. No prior separation of PCB from chlorinated...
DDE thins eggshells and lowers reproductive success of captive black ducks
J. R. Longcore, F. B. Samson, T.W. Whittendale Jr.
1971, Bulletin of Environmental Contamination and Toxicology (6) 485-490
Eggs of captive black ducks fed diets containing DDE at 10 and 30 ppm (dry weight) experienced significant shell thinning and an increase in shell cracking when compared to eggs of untreated black ducks. Eggshells from dosed ducks were: 18-24 percent thinner at the equator than shells from undosed...

The correct date of publication of numbers in the well-known North American Fauna series, begun in 1889, was printed on the cover of each issue through No. 48. After that time dates of publication that appear on the covers are either incomplete or incorrect. For taxonomic purposes, for developing a...
