| Sumario: | This research have the objetive propose a study methodology to evaluate airquality in a mining activity based on the confiability and analysis of meteorological,topographic and emission data, which are entered into the dispersion model. Themethodology was applied to the emissions the particulate material with a sizesmaller than 10 μm (PM10) generated from the operation of open pit quarries, nearGeneral Roca town (Argentina); and then evaluates their dispersion and possibleimpact on human health and / or the environment. The seasonal variations of thedispersion were analyzed and the Gaussian dispersion model used is AERMOD. Theresults showed that PM10 dispersion in different atmospheric conditions andemissions in 2010, don ́t influence urban areas near quarries and don ́t that exceedthe legal limit. From the analysis of the seasonal variations of the dispersion changeswere observed in the extension of the plume and in the maximum hourlyconcentration, especially in the autumn and winter seasons. The results of themodeling (maximum hourly concentration values) were compared with aerosolconcentration data, obtained by remote sensors; Resulting in a determinationcoefficient (R2 ~ 0.7). The proposed work methodology can be incorporated as acontrol tool in government agencies for the evaluation and management of airquality so as to prevent unsatisfactory scenarios. |
