Tomatoes, eggplants, and Japanese leek were sprayed with organophosphorus agricultural chemical, washed with water, and amount of residual chemical was determined. It was thereby considered that if a person ate these vegetables in a daily quantity of 80g per adult, about 10mg or so of organophosphorus from the agricultural chemical would be taken into the body. This quantity and about 10-fold quantity were added to baby diet, and albino rats were fed these diets for about 50 days. This experiment was repeated three times.
Addition of Sumithion (O, O-dimethyl-O-(4-nitro-m-tolyl) thiophosphate) emulsion hindered the growth of rats but this hindrance was inhibited by the addition of eggs or beef liver to the diet, the effect of liver being especially great. Addition of eggs or liver had no such inhibitory effect when the amount of Sumithion emulsion added was larger (about 10-fold). Addition of ethanol with Sumithion emulsion resulted in death of over 50% of the rats after 10 days of feeding.
