ENVIRONMENTAL
DATA


N O T E S

Health effects of exposure to the substance have been investigated, but none has been found. Calcium carbonate exists in nature as mineral aragonite and calcite (as in limestone, chalk and marble).
Card has been partially updated in February 2009: see Occupational Exposure Limits.
