Nationwide organochlorine and mercury residues in wings of adult mallard and black ducks during the 1969-70 hunting season Nationwide organochlorine and mercury residues in wings of adult mallard and black ducks during the 1969-70 hunting season

Nationwide monitoring of organochlorine and mercury residues in wings of approximately 5,200 adult mallards and black (ducks bagged during the 1969-70 hunting season showed DDE, as in 1965 and 1966, to be the predominant residue. PCB's were next in overall prevalence, followed by mercury, DDT, dieldrin, DDD, and heptachlor epoxide. There was no indication of a decrease in levels from...

Summer behavior of immature radio-equipped woodcock in central Maine Summer behavior of immature radio-equipped woodcock in central Maine

The behavior of 15 immature American woodcock (Philohela minor) was studied in central Maine during the summers of 1969 and 1970 using radiotelemetry. The monitored birds used a variety of nocturnal sites including old fields, bogs, powerlines, highway medians, woods roads, and fore clearings. Old fields were occupied more often than any other type of opening. Second growth-hardwoods...

Tests of pesticidal synergism with young pheasants and Japanese quail Tests of pesticidal synergism with young pheasants and Japanese quail

Thirteen pairs of chemicals involving 18 pesticides and two polychlorinated biphenyl preparations were each fed for 5 days to Japanese quail or ring-necked pheasant chicks 7 to 16 days of age. Malathion + EPN, and malathion + trichlorofon were moderately synergistic in tests with both species, whereas joint toxicities of the other chemicals tended to be additive. Comparisons with other...

Organochlorine pesticides and polychlorinated biphenyls in black duck eggs from the United States and Canada--1971 Organochlorine pesticides and polychlorinated biphenyls in black duck eggs from the United States and Canada--1971

Black duck (Anas rubripes) eggs were collected in 1971 from the Northeastern United States and Canada. All 61 eggs analyzed contained DDE residues; the mean DDE residues for States and Provinces ranged from 0.09 to 5.94 ppm on a wet-weight basis, with.mean concentrations exceeding 1.0 ppm in eggs from Maine, New York, New Jersey, and Delaware. The highest DDE concentration, 14.0 ppm, was...
