Abstract:

Different amounts of heptachlor-treated wheat seed containing 365 ppm heptachlor and 105 ppm trans-chlordane were fed to pheasants for different lengths of time, and residues in muscle, liver, brain and fatty tissues were determined at various times later. In genera], residues of heptachlor peroxide (HE) in body tissues were related to the number of treated seed fed and the length of feeding time. Pheasants that were fed only 5 treated seed/day for 15 days had 0.17-0.23 ppm and 1.16-1.60 ppm HE ill liver and fat, respectively, 14 days later, Feeding of 10 or 20 seed/day for 15 days resulted in higher levels of residues in all tissues. Consumption of only 5 or 20 treated seed by the pheasants in I day resulted in only 0.02 to 0.06 ppm HE in liver even after 14 days. Pheasants . that were fed as many treated seed as they would eat (700-1240 seed or 9.9-17.5 mg of toxicant) in I day had - very high levels (up to 32.5 ppm in fat) of residues I day later. Although residue levels of all tissues decreased present in fat and muscle, respectively, even after 90 days

Pheasants that were fed as many 14C-lindane-treated with time, about 1.0 ppm and up to 0,07 ppm HE was seed as they would eat (525-860 seed or 9-14.8 rug of toxicant) in I day had up to 1.12 and 2.48 ppm residue in muscle and liver, respectively, I day later. But these levels decreased very rapidly, and no residue could be seed dressings are less hazardous to seed-eating birds than detected even after 14 days. It is suggested that lindane heptachlor seed dressings and that the use of heptachlor should be discontinued.
