Study on the toxicity of polyoxyethylene tallow amine to three aquatic organisms
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.
