Beschreibungen/Notizen

• Particulate matter concentrations were measured in five size ranges, during an annual period, at the National University Campus in Mexico City. Size distribution indicated high particulates values in the size ranges from 3.0 to > 7.2 mu m and from 0.49 to 1.5 mu m. The cascade impactor concentration represented 30% of the total suspended particles (TSP) values, with a correlation of 0.6 between them. No significative seasonal difference in the mass particulate size distribution was found, but in the rainy season a slight increase in fine particles with respect to the total mass impactor was found. The application of a respiratory model showed that maximum mass of coarse particulates deposition in the thoracic region was of 27 mu g hr super(-1). The highest concentration of fine particulates deposition reached only 13 mu g hr super(-1), in activity.
