title: One-generation reproduction toxicity study of mancozeb and lead acetate.
abstract: The reproduction toxicity of lead acetate and 80% mancozeb containing fungicide formulation (Dithane M-45) were studied on rats. The lead acetate was applied in diet at the following dose groups: Control-1,000-5,000-10,000 mg/kg. Three treatment and a control groups were applied, 4,500 mg/kg Dithane M-45 was administered in all the dose levels simultaneously in diet. The basis of the method was the OECD Guideline for Testing of Chemicals No. 415. Clinical symptoms and mortality were not found in the parent generation. The body weight of female animals diminished significantly before the pregnancy period. This tendency was also seen on males after the combination treatment. Remarkable body weight growth of female animals was observed during lactation period at the two high dose levels. Diminished body weight data of offsprings were measured after treatment at the end of the lactation period. The histological examination showed a general tubulonephrosis in the trial. Summing up, it can be established the administration of fungicide Dithane M-45 did not increase the toxicity of lead acetate.
