【摘要】 在室内条件下测定了牛脂胺聚氧乙烯醚（98%）对斑马鱼、大型溞和羊角月牙藻的急性毒性及对大型溞的繁殖毒性。结果表明，牛脂胺聚氧乙烯醚对供试3种水生生物均有一定的急性毒性效应，毒性等级均为中等毒；对大型溞21 d繁殖毒性NOEC为0.177 mg/L,LOEC为0.248 mg/L。在使用牛脂胺聚氧乙烯醚加工农药制剂的过程中，应关注其对水生生物的潜在风险，以避免或减少其对水生生态系统的危害。更多还原

【Abstract】 The acute toxicities of polyoxyethylene tallow amine(98%) to Brachydanio rerio, Daphnia magna and Pseudokirchneriella subcapitata, and its reproductive toxicity to Daphnia magna were determined in laboratory. The results indicated that polyoxyethylene tallow amine had median acute toxicity to three tested aquatic organisms. The 21-day reproductive toxicity NOEC for Daphnia magna was 0.177 mg/L, and the LOEC was 0.248 mg/L. Therefore, in the process of using the pesticide adjuvant polyoxyethylene tallow amine to process pesticide formulations, attention should be paid to its potential risk to the aquatic organisms, in order to avoid or reduce its hazard to aquatic ecosystems.更多还原
