Abstract | Dermal exposure to the paraquat concentrate may result in severe skin irritation. Diluted spray solutions may produce slight to moderate irritation. Paraquat is absorbed through the skin. In toxicity studies conducted in the laboratory the authors found that the acute dermal LD50 in rats was 80 mg paraquat/kg body weight in males and 90 mg/kg in females, while the acute oral LD50 in male rats was 100 mg/kg and in females 110 mg/kg2. These findings indicate that there does not seem to be a great difference between the oral and dermal toxicity in rats. |
