It was used to control fire ants, and as a flame retardant in plastics, rubber, paint, paper, and electrical goods. However, its used was banned in 1976 due to its toxicity and nature as a persistent organic pollutant. (L601, L617). Mirex is only moderately toxic in single-dose animal studies (oral LD50 values range from 365\u04203000 mg/kg body weight).[6] It can enter the body via inhalation, ingestion, and via the skin. The most sensitive effects of repeated exposure in animals are principally associated with the liver, and these effects have been observed with doses as low as 1.0 mg/kg diet (0.05 mg/kg body weight per day), the lowest dose tested. At higher dose levels, it is fetotoxic (25 mg/kg in diet) and teratogenic (6.0 mg/kg per day). Mirex was not generally active in short-term tests for genetic activity. There is sufficient evidence of its carcinogenicity in mice and rats. Delayed onset of toxic effects and mortality is typical of mirex poisoning. Mirex is toxic for a range of aquatic organisms, with crustacea being particularly sensitive."}]
