abstract = {A critical analysis of Chile's National Air Quality Information System (NAQIS) is presented, focusing on particulate matter (PM) measurement. This paper examines the complexity, availability and reliability of monitoring station information, the implementation of control systems, the quality assurance protocols of the monitoring station data and the reliability of the measurement systems in areas highly polluted by particulate matter. From information available on the NAQIS website, it is possible to confirm that the PM2.5 (PM10) data available on the site correspond to 30.8% (69.2%) of the total information available from the monitoring stations. There is a lack of information regarding the measurement systems used to quantify air pollutants, most of the available data registers contain gaps, almost all of the information is categorized as "preliminary information" and neither standard operating procedures (operational and validation) nor assurance audits or quality control of the measurements are reported. In contrast, events that cause saturation of the monitoring detectors located in northern and southern Chile have been observed using beta attenuation monitoring. In these cases, it can only be concluded that the PM content is equal to or greater than the saturation concentration registered by the monitors and that the air quality indexes obtained from these measurements are underestimated. This occurrence has been observed in 12 (20) public and private stations where PM2.5 (PM10) is measured. The shortcomings of the NAQIS data have important repercussions for the conclusions obtained from the data and for how the data are used. However, these issues represent opportunities for improving the system to widen its use, incorporate comparison protocols between equipment install new stations and standardize the control system and quality assurance.},

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.},
