Abstract

The effect of short-term exposure to xenobiotics on the feeding behavior of the freshwater rotifer Brachionus calyciflorus was studied. The filtration and ingestion rates of this rotifer decreased after an exposure of 5 hr to sublethal concentrations of copper, pentachlorophenolate, 3,4-dichloroaniline, and lindane. The effective concentrations at which feeding rate was reduced to 50% of that in controls (EC50) for the respective chemicals are 0.032, 1.85, 41.2, and 8.5 mg/liter. The potential use of feeding behavior as test criterion for toxicity screening tests with aquatic invertebrates is discussed.

摘要

研究了短期接触异生物质对淡水轮虫萼花臂尾轮虫摄食行为的影响。该轮虫在暴露于亚致死浓度的铜、五氯酚、3,4 -二氯苯胺和林丹5小时后，其滤过率和摄食率下降。各化学物质使摄食率降至对照水平50%时的有效浓度（EC50）分别为0.032、1.85、41.2和8.5毫克/升。还讨论了将摄食行为用作水生无脊椎动物毒性筛选试验测试标准的潜在用途。
