Abstract
Subchronic toxicity of the mixture of ClO2, ClO2 − and ClO3 − in water on rat was studied through feeding test for 90 days. Statistical analyses of variance on weight gained, food utilization efficiency, indexes of blood and serum, liver/bodyweight and kidney/bodyweight ratios, and histopathological examination on liver and kidney were carried out. The results showed that solution of ClO2 and its by-products ClO2 − and ClO3 − at a concentration of 553 mg/L was not toxic.
