RT Report T1 Endosulfan: Environmental Health Criteria 40 A1 United Nations Environment Programme, A1 World Health Organization, A1 International Labour Organisation, K1 environmental health K1 chemical K1 carcinogen K1 toxic substance SN 92 4 154180 6 YR 1984 FD 1984 LK https://wedocs.unep.org/handle/20.500.11822/29342 UL https://wedocs.unep.org/handle/20.500.11822/29342 NO Technical endosulfan (6,7,8,9,10, 10-hexachloro-1,5,5a,6, 9,9a, hexahydro 6,9-methano-2,4,3-benodioxathiepin, 3-oxide) is a brown crystalline substance consisting of alpha- and beta-isomers in the ratio of approximately 7030. It is used in a formulated form as a broad-spectrum contact and stomach insecticide mainly in agriculture and, in some countries, in public health. The method of choice for its determination is gas chromatography combined with electron capture detection. The main source of exposure of the general population is food, but residues have generally been found to be well below the FAQ/WHO maximum residue limits. Because of its use in tobacco farming, smoking may be an additional source of endosulfan exposure. DS UN Environment Document Repository RD Sep 17, 2026
