The absorption of lindane, heptachlor, aldrin, dieldrin and p, p' DDT by frog skin has been studied. Various experiments indicate that water-soluble fractions of these insecticides are selectively absorbed by the skin. The relative quantities of insecticides absorbed appear to be partially related to their water solubilities. Selected studies using isolated frog skin indicate that the passage of insecticides across the skin does not alter the electrical potential difference across the skin. The observed results are discussed with respect to the accumulation of these chemicals in the tissues of the frogs.
