abstract = {The long-term trends and spatial variability of PM2.5 and PMio over the period between 2000 and 2012 in the Santiago Metropolitan Area, Chile are studied. The annual PMio and PM2.5 mass concentration ranged between 76 5 and 52 41.ig [T1-3 and between 32 4 and 24 3, respectively. The large levels of PM observed during the cool season (April September) compared to the warm season (October March) can be explained by meteorological conditions and increased emissions. PM2,5 represents approximately 45% 5% and 60% 10% of PM10 in the warm and cold seasons, respectively. Reductions in PMio and PM2.5 were observed in the ranges of 2.46 to 0.31 and 3.17 to 1.80% yearl, respectively. For the city, the comprehensive air pollution level declined gradually, illustrating that the air quality improved over the last decade. However, the air quality standards were still being exceeded, indicating the need to update and strengthen the policies to control PM pollution.},

abstract = {Particulate matter, the main pollutant in the atmospheric environment of the Santiago city in winter, was analyzed by means of the major water-soluble ionic species obtained under critical episodes of pollution in 2003. The particulate matter samples were collected using the Micro-Orifice uniform deposit impactors, with eight impactor stages connected in series, and the ionic species in particulate matter samples at each stage was analyzed by ion chromatography. While sulfate ion and nitrate ion showed bi-modal distributions, peaking in the fine and coarse mode, ammonium ion displayed a bi-modal size distribution, peaking in the fine and ultra fine mode. The equivalent concentration ratio of ammonium to sulfate was 2.03 +/- 0.09, indicating the complete neutralization of sulfuric acid by ammonia. The excess ammonium ion was associated to nitrate ion. The study of the size distribution of water-soluble inorganic ions in particulate matter supports the notion that secondary aerosols play a significant role in the urban atmosphere.},
