Andrea Hartwig, MAK Commission
The German Senate Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area (MAK Commission) reviewed its toxicological evalu-ation of dichlorofluoromethane [75-43-4]. Dichlorofluoromethane and other partly halogenated chlorofluorocarbons are no longer approved in the European Union or in Germany. The derivation of the previous MAK value of dichlorofluoromethane does not correspond with the current approach of the Commission. There are no new studies that would allow the MAK value to be revised. The MAK Commission decided that a new evaluation is not of high priority. The MAK value and the other classifications are therefore suspended, and the substance is listed in the Section II c of the List of MAK and BAT Values for substances no longer evaluated.
