| 中文摘要 |
| 速灭杀丁(Fenvalerate,Sumicidin 20% EC),又叫杀灭菊酯、戎酸氰醚酯、氰戎菊酯、S-5602。商品名叫来福灵,化学名称为a氰基-3-苯氧基苄基-2-(4-氯苯基)-3-甲基丁酸酯。 |
| 英文摘要 |
| In this paper, the experimental result shows that 24h EC50 (median effective concentration) value is 2.5ppb (range 1.8—3.2ppb), 48h EC50 0.049ppb (range 0.032—0.1ppb) and 96h EC50 0.0128ppb (range 0.01—0.016 ppb). The LC50 (lethal concentration fifty) values are 25.88ppm (18—32ppm) at 24h, 0.133ppb (0.1—0.18ppb) at 48h and 0.017ppb (0.01—0.022ppb) at 96h for Female-rate by using Daphnia magna. The result of nonlethal concentration is 0.0001ppb at 96h and 100% lethal concentration 0.0032ppb at 96h. That means Fenvalerate is highly toxic to aquatic organism.The bioassay system of Daphnia magna is a method of rapid, sensitive and inexpensive screening procedures for new pesticides, according to the authors. |
