Dieldrin accumulation in tissues of the sheep

One hundred thirty-five sheep were fed dieldrin at levels of 0, 0.5, 1.0, 2.0, and 4.0 mg per kg body weight for up to 32 weeks, and accumulation of dieldrin in the tissues was measured. Four mg dieldrin per kg was lethal to most sheep in less than 4 weeks. Correlations of dieldrin in fat of bone, b...

Summary:One hundred thirty-five sheep were fed dieldrin at levels of 0, 0.5, 1.0, 2.0, and 4.0 mg per kg body weight for up to 32 weeks, and accumulation of dieldrin in the tissues was measured. Four mg dieldrin per kg was lethal to most sheep in less than 4 weeks. Correlations of dieldrin in fat of bone, brain, carcass, adipose tissue, heart, muscle, and spinal cord with that in blood were high. Correlations of dieldrin accumulated in blood with that in plasma or kidneys were low. Dieldrin accumulation in the tissues was readily affected by level of dieldrin in the ration, but it was not affected by the level or source of energy in the ration. It is suggested that samples of bone would be suitable for monitoring chlorinated hydrocarbon insecticides in marketable meats.
