Chlorobenzenes other than hexachlorobenzene : environmental aspects | |||||

Autor: H. M. Malcolm, Paul Howe, S. Dobson AnotaceChlorobenzenes are a group of cyclic aromatic compounds in which one or more hydrogen atoms of the benzene ring have been replaced by a chlorine atom. They are used mainly as intermediates in the synthesis of pesticides and other chemicals; 1 4-DCB is used in space deodorants and as a moth repellent. The higher chlorinated benzenes (TCBs and 1 2 3 4-TeCB) have been used as components of dielectric fluids. This CICAD on chlorobenzenes, other than hexachlorobenzene, is an update of the Environmental Health Criteria publication (EHC)128 - Chlorobenzenes other than hexachlorobenzene (1991). Because no significant change to the human health assessment beyond the EHC was considered necessary, this CICAD concentrates on environmental aspects. The risk of chlorinated benzenes causing harm to aquatic organisms is considered to be low. Few data are available on the effects of chlorobenzenes on terrestrial systems. Dostupné zdroje
