TOXICITY OF DICHLORO-DIPHENYL-TRICHLORETHANE (DDT) TO GOLDFISH AND FROGS

Abstract

Single doses of DDT in olive oil, when swallowed as pellets by 6-10 g. goldfish, were lethal in amts. ranging from 63-200 mg./kg., the total mortality being 55% after 1-621/2 days. The signs resembled picrotoxin or phenol poisoning. Single doses of 150 mg./kg. injd. into the dorsal lymph sac killed all frogs tested after 4-72 hrs.
