| Abstract |
2-Bromopropane (2-BP), used as an alternative to chlorofluorocarbons in a Korean electronics factory, caused reproductive and haematopoietic disorders in male and female workers. After identification of 2-BP toxicity, 1-bromopropane (1-BP) was introduced as an alternative. 1-BP was considered less mutagenic than 2-BP, but subsequent animal experiments revealed 1-BP to be a potent neurotoxic substance. It was also revealed that 1-BP has reproductive toxicity, but with target cells that are different from those of 2-BP. After the first animal study describing the neurotoxicity of 1-BP, human cases were reported showing decreased vibration perception, paraesthesia in the lower extremities, decreased sensation in the thighs, ventral and gluteal regions, stumbling and headache, as well as mucosal irritation. More work is necessary on the dose-response of bromopropanes in humans and on the mechanisms underlying the differences in toxic effects between the two bromopropanes. |
