Abstract/Summary
|
-
The German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area has re‐evaluated the BLW (“Biologischer Leitwert”) for methyl bromide, using bromide in serum/plasma to characterise 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 of 12 mg bromide/l plasma or serum was confirmed. The sampling time for long‐term exposure is at the end of exposure/shift after several previous shifts. The evaluation of an EKA for methyl bromide in the air and S‐methylcysteine‐albumin adducts in blood is not possible as there is insufficient data available.
