“…Neb. 68103 Using samples from the same experimental birds, Greichus et al (1968) reported a 95% procedure efficiency for extracting dieldrin-14C with a Florisil column from pheasant tissues, eggs, and feces. Following extraction, samples were divided into two equal parts by volume.…”

The distribution and excretion of dieldrin-14C in 18 laying hen pheasants were studied by administration of a single gelatin capsule containing 1.4 mg. of dieldrin labeled with 5.5 microcuries. Dieldrin residues were detected using electron capture gas chromatography and liquid scintillation counting in tissues 2 hours after treatment.Highest average level of residues occurred in all tissues after 6 hours with fat having 6.45 p.p.m.; liver 1.56 p.p.m.; and brain, heart, and muscle less than 0.3 p.p.m. Three birds appeared to absorb 86, 89, and 97 % of the 1.4 mg. of administered dieldrin. Birds killed 5 weeks after treatment excreted 26.5, 21.5, and 18.2% of the dieldrin in their feces; 11.5, 14.4, and 13.0% in their eggs; and 34.6, 21.2, and 32.7% remained in the body. Indirect evidence indicated water-soluble metabolites in the feces but not in egg yolks, while no evidence of ether-soluble metabolites was found in eggs or tissues.
