The German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area (MAK Commission) re-evaluated the occupational exposure limit value (maximum concentration at the workplace, MAK value) for calcium sulfate (respirable fraction). In 2012, the general threshold limit value for the respirable fraction (R fraction) of dust was revised, resulting in the concept of “granular biopersistent dusts”. However, due to its proven solubility, calcium sulfate cannot be regarded as biopersistent. Data to derive a specific MAK value (maximum concentration at the workplace) are not available. Therefore, the MAK value and the assignment to Pregnancy Risk Group C for the respirable fraction of calcium sulfate are withdrawn.
