Chronic toxicity of lead to three freshwater invertebrates-Brachionus calyciflorus, Chironomus tentans, and Lymnaea stagnalis

Chronic toxicity of lead to three freshwater invertebrates-Brachionus calyciflorus, Chironomus tentans, and Lymnaea stagnalis

Chronic lead (Pb) toxicity tests with Brachionus calyciflorus, Chironomus tentans, and Lymnaea stagnalis were performed in artificial freshwaters. The no‐observable‐effect concentration (NOEC), lowest‐observable‐effect concentration (LOEC), and calculated 20% effect concentration (EC20) for the roti...

Zusammenfassung:Chronic lead (Pb) toxicity tests with Brachionus calyciflorus, Chironomus tentans, and Lymnaea stagnalis were performed in artificial freshwaters. The no‐observable‐effect concentration (NOEC), lowest‐observable‐effect concentration (LOEC), and calculated 20% effect concentration (EC20) for the rotifer B. calyciflorus were 194, 284, and 125 μg dissolved Pb/L, respectively. The midge C. tentans was less sensitive, with NOEC and LOEC of 109 and 497 μg dissolved Pb/L, respectively, and the snail L. stagnalis exhibited extreme sensitivity, evident by NOEC, LOEC, and EC20 of 12, 16, and
