[Studies on photochemical disinfectant enamelled-ware of toxicity experiments]

In order to understand the toxicity of photochemical disinfectant enamelled-ware to human body, systematic toxicity studies were carried out. The results showed that the concentrations of toxic metal stibium (Sb) and cadmium(Cd) in photochemical disinfectant enamelled-ware 0.01 ml/L and 0.02 mg/L and lead (Pb) was non-detectable. The amount of LPO lipid peroxides in the experiment group and control group had no significant difference(t = 0.3481, P > 0.05). The drinking water of photochemical disinfectant had no effect on gene mutation in Ames test, and didn't make increase micronucleus formation of mice bone marrow and sperm deformity in the teratogenesis test of mice. It suggested that the photochemical disinfectant enamelled-ware was not toxic to human body. It was safe to human and could be used widely.
