Levels of respirable dust and respirable crystalline silica at construction sites
The purpose of this pilot study was to assess the potential for inadvertent exposure of the public to respirable crystalline silica (RCS) from construction activities. The study assessed the respirable dust (RD) from, demolition, block cutting, road building, general construction activities and city centre air from 13 visits to 7 sites. In total, 48 samples from the construction activities and 11 city centre air samples, for comparison, were collected. The results obtained for RD and RCS were generally very low.
