Résumé

Objective To assess the toxicity risks of diphenylchlorarsine (DA) to environments, human beings and livestock. Methods Totally 120 mice were randomly divided into 6 groups and given DA by gastric gavage at the doses of 32, 30, 28, 26, 24, 22 mg/kg respectively for LD_(50) of DA in mice. The toxicity of DA in rat skin were evaluated by smearing 50 ?l DA at the concentrations of 140, 70, 35, 17.5, and 8.8 mg/ml to an area of 4 cm2, and that of eyes exposure was carried out by dropping 10 ?l DA of 140.7, 70, 7, 0.7 mg/ml in rat eyes. The counterpart skin area and eyes served as control. Results LD_(50) of DA in mice was 28.07 mg/kg, the estimated doses for no-observed-adverse-effect levels (NOELs) were 8.8 mg/ml (0.44 mg) to the skin and 0.7 mg/ml (0.014 mg) to the eyes respectively. Conclusion DA can induce the injuries on the liver, kidneys, esophagus and stomach. High concentration of DA can cause inflammation of the skin and lens opacification, even blind.
