Endosulfan is an organochlorine insecticide and acaricide that is highly toxic and can accumulate in organisms. It is produced in India and breaks down slowly, remaining in soil for around 6 years.

2. WHAT IS ENDOSULPHAN? Endosulphan is an organ chlorine insecticide and acaricide . This colorless solid has emerged as a highly controversial agrichemical due to its acute toxicity , potential for bioaccumulation , and role as an endocrine disruptor .
3. PRODUCTION In India, Hindustan insecticide lmtd. Is the producer of endosulphan. Endosulfan is a derivative of hexachlorocyclopentadiene and is chemically similar to aldrin , chlordane , and heptachlor . Technical endosulfan is a 7:3 mixture of stereoisomers , designated α and β
