Abstract/Summary
|
-
The German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area has re‐evaluated the “Biologischer Leitwert” (BLW) for methyl bromide, using bromide in serum/plasma to characterize the internal exposure. The critical effect of methyl bromide is a high acute and chronic neurotoxicity. It can pass through the skin so that biological monitoring is highly recommended. On the basis of results of a human study the occurrence of abnormal findings in the EEG is comparable for unexposed persons and persons with exposure to methyl bromide in concentrations below 12 mg bromide/l plasma. Thus the BLW value of 12 mg bromide/l plasma or serum was confirmed. The sampling time is at the end of exposure/shift after several previous shifts.
