Abstract/Summary
|
-
The German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area has re‐evaluated dichloromethane, considering dichloromethane in blood to characterize the internal exposure. In a chamber study, 14 non‐smokers were exposed to different concentrations of dichloromethane. After exposure to the present MAK‐value of 50 ml dichloromethane/m3 without physical activity, a concentration of 0.3 mg dichloromethane/l blood was measured. Considering an increased intake due to elevated breathing volume during work, the exposure to 50 ml dichloromethane/m3 results in a blood concentration of 0.5 mg/l. Taking into account this study and the EKA correlation of 2001, a BAT‐value of 500 µg dichloromethane/l blood was evaluated. Sampling time is straight after exposure.
