Organochlorine pesticide, PCB, and PBB residues and necropsy data for bald eagles from 29 states - 1975-77 Organochlorine pesticide, PCB, and PBB residues and necropsy data for bald eagles from 29 states - 1975-77
During 1975-77, 168 bald eagles (Haliaeetus leucocephalus) found moribund or dead in 29 states were analyzed for organochlorine pesticides and polychlorinated biphenyls (PCBs); 32 specimens from 13 states were analyzed for polybrominated biphenyls (PBBs). PCBs were present in 166 bald eagle carcasses and DDE was found in 165. TDE and dieldrin were identified in 137 samples, trans...

Dopamine and norepinephrine depletion in ring doves fed DDE, dieldrin, and Aroclor 1254 Dopamine and norepinephrine depletion in ring doves fed DDE, dieldrin, and Aroclor 1254
The levels of dopamine and norepinephrine were measured in one-half of the brain of ring doves fed a control diet or a diet containing 2, 20, or 200 ppm DDE; 1, 4, or 16 ppm dieldrin; or 1, 10, or 100 ppm Aroclor 1254. Levels of DDE, dieldrin, or Aroclor 1254 were determined in the other half of each brain. The intermediate and high levels of each chemical caused depletions in both

Metastatic, papillary cystadenocarcinoma of the mammary gland in a black-footed ferret Metastatic, papillary cystadenocarcinoma of the mammary gland in a black-footed ferret
A simple, papillary cystic adenocarcinoma of the mammary gland with metastases to the internal iliac and mesenteric lymph nodes, liver, and spleen was observed in a 12 to 13 year old female black-footed ferret (Mustela nigripes). Histologically, the tumor was aggressive, and lymphatic invasion was found. Attempts at virus isolation were negative. Other findings were bilateral infarcts in...

Disseminated visceral coccidiosis in whooping cranes Disseminated visceral coccidiosis in whooping cranes
Three 13- to 18-day-old whooping cranes (Grus americana) and a 9-year-old whooping crane died in outdoor pens at the Patuxent Wildlife Research Center. The deaths were associated with an overwhelming systemic infection by an intracellular protozoan parasite, which resulted in enteritis, granulomatous bronchopneumonia, hepatitis, splenitis, and myocarditis. The clinical, histopathologic...

Lead residues in eastern tent caterpillars (Malacosoma americanum) and their host plant (Prunus serotina) close to a major highway Lead residues in eastern tent caterpillars (Malacosoma americanum) and their host plant (Prunus serotina) close to a major highway
Eastern tent caterpillars, Malacosoma americanum (F.) (Lepidoptera: Lasiocampidae), and leaves of their host plant, black cherry, Prunus serotina Ehrh., were collected in May, 1978, at various distances from the Baltimore-Washington Parkway, Prince George's Co., MD, and were analyzed for lead by atomic absorption spectrophotometry. Caterpillars collected within 10 m of the parkway...

Persistence in earthworms and potential hazards to birds of soil applied DDT, dieldrin, and heptachlor Persistence in earthworms and potential hazards to birds of soil applied DDT, dieldrin, and heptachlor
(1) DDT, dieldrin, and heptachlor were each applied to separate replicate plots in a hay field at 0.6, 2.2, or 9.0 kg/ha. For 11 yr thereafter, soil and earthworms were analysed for residues. (2) The average ratios of residues in earthworms (dry weight) to residues in soil (dry weight) were: total DDT, 5; dieldrin, 8; and heptachlor epoxide, 10. The average time for the initial residues...
