Notes
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.
