Tissue residues of dieldrin in relation to mortality in birds and mammals
An experiment was performed with Coturnix to learn what residue levels were indicative of death from dieldrin poisoning. Birds were fed diets containing 250, 50, 10, and 2 ppm dieldrin for periods up to 158 days. The dieldrin was 95% pure HEOD, which is 1,2,3,4,10,10-hexachloro-6, 7.epoxy. l,4,4a,5,6,7,8,8a-octahydro-l,4-endo,exo-5,8- dimethanonaphthalene. When half of a group was dead, the oth
