Hence, like any other environmental issue, dealing with air pollution requires of a systemic approach in which suites of tools ranging over a broad span of disciplines and considerations are applied.
Dispersion modeling is one of the necessary tools to assess air pollution.
5 million people city, located in a basin in the central part of Chile by the high Andes, frequently exceed national and international air quality standards. This seriously affects peoples health as well as it stresses vegetation. Similar risks are posed to the population of other major cities in Central Chile and in the surroundings of large pollution sources such as the copper smelters and power plants located in the area. Main results of the first attempt to assess the regional distribution of oxidized sulfur by means of a regional-scale modeling system are summarized. Preliminar results are presented.
