Abstract
To investigate the quality of surface water and groundwater, and the airborne asbestos concentrations in ambient air near the Dong-a inactive mine, 21 water samples and 20 airborne samples were collected and analyzed. As a result, Anthophyllite fibers were detected in monitoring well at the quarry and no asbestos fibers were detected in other groundwater samples. On the other hand, 8 samples among 13 groundwater samples exceeded the standard for drinking water, especially for F- and NO3-N. Analyzed by PCM, the concentrations of airborne fibers in ambient air without site activity ranged between 0.0025 f/cc and 0.0029 f/cc at 8 samples of 20 airborne samples, below the guideline for indoor air quality (0.01 f/cc). However, additional airborne sample results by PCM indicated higher concentrations (0.0025~0.6130 f/cc) of fibers in the air based on four site activity scenarios (i.e. plowing, sweeping, weeding and grass cutting). Even though asbestos fibers were not detected in the ambient air samples by transmission electron microscopy, airborne asbestos fibers can be exposed to ambient air by agricultural activities. Therefore, in order to identify potential impact on surrounding receptors owing to airborne asbestos caused by site activities, site-specific studies such as risk assesment based on activity-based sampling are required.
