Analysis of Egg Yolk and Poultry Tissues for Chlorinated Insecticide Residues

Residues of lindane and its metabolites in eggs, chicks, and body tissues of hen pheasants after ingestion of lindane‐14C via treated wheat seed or gelatin capsules1

“…The treated seed was thoroughly mixed for about 4 hours and stored in plastic bags at 0 C until used. 14 14…”

“…act. of 131.4 myCi/mg (292 dpm/vig) 14 and used for treating the wheat seed. The lindane-C (1.479 g) was dissolved in 650 ml acetone containing 2 ml of ethylene glycol and 2 ml of Triton-X-100 (Rohm and Haas Co.).…”

“…Several studies have been carried out in the past on residues in eggs and body tissues of hens that had been fed lindane 7 10 . Burrage and Saha 11 reported on residues in the body tissues of pheasants after feeding on wheat seed treated with 14 heptachlor or lindane-C. This type of work is important for evaluating the hazard of insecticides to seed-eating birds.…”

“…14 Residues in eggs. Almost all C-labeled residues in eggs were present in the yolk, and none in the albumen.…”

“…Non-metabolized14 lindane accounted for about 18* of the C-labeled residues in the methanol extract of the chicks hatched from eggs collected 5 and 6 days after feeding with capsules. Smaller amounts of lindane were present in chicks hatched from eggs collected at later dates.…”
