用改进的寇氏法研究氯化汞对金鱼的急性毒性,其目的在于评价水环境中Hg^2+对鱼类的影响,探讨评价重金属Hg^2+对生物体的毒性作用.试验结果表明,水温(18±2)℃时,氯化汞对金鱼24、48、72、96h的TLm分别为0.376、0.244、0.159、0.148mg/L;95%可信限分别为0.276~O.511、0.172~0.347、0.116~0.217、0.106~O.205mg/L;估算安全质量浓度为0.0148mg/L.
用改進的寇氏法研究氯化汞對金魚的急性毒性,其目的在于評價水環境中Hg^2+對魚類的影響,探討評價重金屬Hg^2+對生物體的毒性作用.試驗結果錶明,水溫(18±2)℃時,氯化汞對金魚24、48、72、96h的TLm分彆為0.376、0.244、0.159、0.148mg/L;95%可信限分彆為0.276~O.511、0.172~0.347、0.116~0.217、0.106~O.205mg/L;估算安全質量濃度為0.0148mg/L.

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.
