Static bioassay tests were conducted using commercial grade endosulfan 35EC to study its toxicity during different seasons to two species of Lamellidens from the Godavari river at Paithan (Maharashtra State). Acute toxicity studies for 96 h showed that both species of Lamellidens were more sensitive to endosulfan 35EC in summer, at times of high temperature, pH and total carbonate content of the water used, than in monsoon and winter. LC0 and LC50 values were determined for L. corrianus and L. marginalis, during summer, monsoon and winter. Statistical analyses showed that both species were more sensitive during summer (P less than 0.001) than in monsoon and winter and that L. marginalis was more sensitive to endosulfan 35EC than L. corrianus in summer (P less than 0.001). Behavioural changes and mortality of the bivalves were dose-related. Regression equations and 95% confidence limits for each species were established in different studies. The results are discussed in the light of possible effects of endosulfan on these species of bivalve molluscs.
使用商业级硫丹35乳油进行静态生物测定试验，以研究其在不同季节对来自派坦（马哈拉施特拉邦）戈达瓦里河的两种丽蚌的毒性。96小时的急性毒性研究表明，在夏季，即水温较高、pH值和水中总碳酸盐含量较高时，两种丽蚌对硫丹35乳油的敏感性均高于季风期和冬季。测定了夏季、季风期和冬季科氏丽蚌和缘板丽蚌的LC0和LC50值。统计分析表明，两种丽蚌在夏季（P小于0.001）比在季风期和冬季更敏感，且缘板丽蚌在夏季对硫丹35乳油的敏感性高于科氏丽蚌（P小于0.001）。双壳贝类的行为变化和死亡率与剂量相关。在不同研究中建立了每个物种的回归方程和95%置信限。根据硫丹对这些双壳贝类可能产生的影响对结果进行了讨论。
