MNM Area Samples Data Set

Description:

The MNM Area Samples data set contains information on samples taken at metal and non-metal (M/NM) mines and the specific locations where those samples were collected. These samples are used to assess environmental conditions related to airborne contaminants within specific areas of a mine rather than focusing on individual miner exposure.
