DDT Persistence in Wild Hares and Mink
Preview not available

Abstract

Residue data in wild hares (Lepus americanus) and mink (Mustella vison) following light applications of DDT to the forest are presented. Residues of from 0.5 to 2.6 ppm DDT and its metabolites are shown to persist in mink up to 9 years after a single application of 1 lb/acre. Results of analyses of adult hares and hare fetuses show low residue levels throughout 10 years following spraying that are not significantly different (P < 0.05) from levels found in hares from untreated forests. Patterns of DDT residue levels and persistence shown for these species are compared with similar patterns shown for other mammalian herbivores and predators.
