A type of organochlorine insecticide, a general term for cyclic diene insecticides. Synthesized by the Diels-Alder reaction, examples include aldrin, dieldrin, and endrin. They are stable in alkaline conditions, and when mixed with alkaline pesticides and fertilizers, they are effective in eliminating soil pests. However, because they are highly residual and have extremely high toxicity (TL m value) to freshwater fish, their manufacture and use are regulated by the Agricultural Chemicals Control Law. Currently, only endosulfan (LD 50 80-100 mg/kg (rat, oral)) remains registered. Source: Morikita Publishing "Chemical Dictionary (2nd Edition)" Information about the Chemical Dictionary 2nd Edition |
