Abstract

Comparative toxicity of several pesticides, lindane, endosulfan, pentachlorophenol (PCP),3,4-dichloroaniline (DCA) and copper sulphate has been tested to determine their lethality in two species of freshwater invertebrates, Daphnia magna and Brachionus calyciflorus. D. magna was more sensitive than B. calyciflorus to all the toxicants tested except to copper sulphate. DCA was the most toxic compound to D. magna and was followed in order of decreasing toxicity by copper sulphate, PCP, endosulfan and lindane. Copper sulphate was the most toxic chemical tested to the rotifer B. calyciflorus and was followed by PCP, endosulfan, lindane and DCA. The 24 hr LC50 values (mg/L) for D. magna and B. calyciflorus, respectively, were: lindane, 1.64 and 22.5; endosulfan, 0.62 and 5.15; DCA, 0.20 and 61.5; PCP, 0.39 and 2.16; copper sulphate, 0.38 and 0.076.

摘要

已对几种农药（林丹、硫丹、五氯苯酚（PCP）、3,4-二氯苯胺（DCA）和硫酸铜）的相对毒性进行了测试，以确定它们对两种淡水无脊椎动物大型溞和萼花臂尾轮虫的致死性。除硫酸铜外，大型溞对所有测试毒物都比萼花臂尾轮虫更敏感。DCA是对大型溞毒性最大的化合物，按毒性递减顺序依次为硫酸铜、五氯苯酚、硫丹和林丹。硫酸铜是对轮虫萼花臂尾轮虫测试的毒性最大的化学物质，其次是五氯苯酚、硫丹、林丹和DCA。大型溞和萼花臂尾轮虫的24小时半数致死浓度（mg/L）分别为：林丹，1.64和22.5；硫丹，0.62和5.15；DCA，0.20和61.5；五氯苯酚，0.39和2.16；硫酸铜，0.38和0.076。
