Notas: According to a recent Environmental Ministry report on National Air Quality, in Chile there are serious problems due to pollution from breathable particulate matter (PM) smaller than 2,5 μm (PM2,5), PM10, O3, and SO2 in several Chilean cities. The atmospheric contamination problem used to be, for many years, almost exclusive to Santiago, but nowadays many mining zones and other northern, central and southern cities in Chile have showed air quality problems, with severe consequences on population health. A detailed review shows that in urban and mining zones in north Chile, the atmospheric contamination are mainly due to high levels of SO2 and PM10, mostly from copper smelters and coal thermoelectric plants, while in central zone, the issue is due to PM2,5, PM10, O3, and SO2 coming from mobile and industries sources. Finally, in Chilean southern urban zones, the main pollutants are PM2,5 and PM10 originated by residential wood combustion for heating and cooking. Besides these zones, which have been declared as saturated or latent, there are some other cities in southern Chile, for example Temuco, Chillán, Coyhaique, Concepción, and Osorno, where PM10 monitoring studies and campaigns have started, showing alarming air quality results.
