Occupational Safety and Hygiene II - Selected Extended and Revised Contributions from the International Symposium Occupational Safety and Hygiene, SHO 2014
The mining industry involved, among other factors, exposure to dust, which affects workers, and also the surrounding populations. In this article, the dispersion of dust in the air environment was studied and the dust sampling was based on the French standard NFX 43 007:2008. The dust flux deposition was determined in twenty-four sampling points located inside and around the quarry. It was verified that the points with higher level of dust correspond to the operating area access, crushing plant, and a national road, with the average of 369.49 mg.m-2.day-1, 337.70 mg.m-2.day -1 and 152.65 mg.m-2. day-1, respectively. The lowest value of dust flux deposition corresponded to a point located in a limit of the quarry, with the value of 14.37 mg.m-2.day-1. Through this study it was concluded that the surrounding population could be affected by the dust quarry, although, the dispersion will greatly depends on the meteorological conditions, among other factors. © 2014 Taylor & Francis Group, London, UK.
