Occupational Exposure in Methyl Bromide Manufacturing Workers: 17-year Follow-up Study of Urinary Bromide Ion Concentration for Biological Monitoring

Field Study of Occupational Exposure to Methyl Bromide

To elucidate the circumstances of their occupational exposure to methyl bromide (MeBr), we conducted a 17-yr study on 124 workers employed by a MeBr manufacturer. Subjects were classified into three groups according to the nature of their work: synthesis group, filling group, and other group. Urinary concentrations of bromide ion (Br-) were assessed, and data attained via MeBr-health examinatio...

Bromine in blood, EEG and transaminases in methyl bromide workers.

In 33 methyl bromide users, slight electroencephalographic changes (in 10 subjects) and a small increase in serum transaminases were found which could be related to bromine concentration in blood. No relationship was found with subjective symptoms, general neurological examination or the results of serum protein electrophoresis.

Methyl bromide under fire.

Methyl Bromide under Fire Methyl bromide is one of the most widely used pesticides in the world, a broad-spectrum fumigant effective in controlling insects, nematodes, fungi, and bacteria. Methyl bromide is also highly toxic to humans. In December 1993, the EPA listed methyl bromide as a stratospheric ozone-depleting substance subject to phase-out. The final rule, issued 1 January 1994, freezes...
