Abstract

The acute toxicity tests of mercury chloride to goldfish were carried out by using Karber method.The purpose was to evaluate the effect of mercury chloride on goldfish and to establish the standard demand upon water quality.The result indicates that when water temperature is(18±2)℃,the TLm of mercuty chloride on goldfish in 24,48,72,96 h is 0.376,0.244,0.159,0.148 mg/L respectively,and the confidence limit of 95% is 0.276~0.511,0.172~0.347,0.116~0.217,0.106~0.205 mg/L,and its mass concentration of safety is 0.014 8 mg/L.
