Abstract | The oral toxicity of the pesticide mirex which is used in the control of fire ants, was studied in Sherman strain rats. The single-dose LD50 was 365 mg/kg and the 90-dose LD50, 6.0 mg/kg in adult female rats. The chronicity factor, which is the ratio of single-dose LD50 to 90-dose LD50 was 60.8. The highest dietary level of mirex tolerated without symptoms of poisoning was 50 ppm. |
