中文摘要:
      在不同水温条件下,采用静水式鱼类毒性试验法,研究镉对倒刺鲃的急性毒性效应。结果表明,在12(±1)℃条件下,镉对倒刺鲃的24、48、72、96 h半数致死浓度分别为14.38、7.18、4.11、3.16 mg/L;在25(±1)℃条件下,镉对倒刺鲃的24、48、72、96 h半数致死浓度分别为10.68、5.77、3.66、2.16 mg/L;两种温度下镉对倒刺鲃的质量安全浓度分别为0.0316、0.0216 mg/L。依据相关分级标准,镉对倒刺鲃属于中毒物质。
英文摘要:
      The acute toxicity o f cadmium (Cd2+) to Spinibarbus denticulatus was studied with the static water fish toxicity test method at different water temperatures. The results showed that, at 12 (±1)℃, the LC50 of 12, 24, 48, 96 h for cadmium to S.denticulatus were 14.38 mg/L,7.18 mg/L, 4.11 mg/L and 3.16 mg/L, while at 25(±1)℃, the LC50 of 12, 24, 48, 96 h were 10.68 mg/L, 5.77 mg/L, 3.66 mg/L and 2.16 mg/L. At the 2 kinds of temperature, the safe concentrations were 0.0316 mg/L and 0.0216 mg/L respectively. According to the grading standards, the cadmium was mediumtoxic to S.denticulatus.
