Air pollution is a major environmental problems facing humanity, particularly in urban areas is becoming increasingly important for the marked tendency to increase the population living in cities. The relationship between air pollution and human health is recognized internationally so it’s monitoring and control in municipalities where population is vital.

The National Environmental Strategy explicitly stated in one of its objectives: "Reduce the rate of mortality due to respiratory diseases" The management of air quality is a complicated and costly since the phenomenon of the dispersion of air pollution depends on factors such as climate variability, the topography, the scale that occurs, the nature of the emission source (fixed and mobile), synergistic phenomena analyzed by combining certain contamination and monitoring equipment used in both emissions as of the release.

In developing countries like Brazil, Argentina and Chile, initiatives have been implemented for the Management of Urban Air Quality and sponsored by institutions and international agencies of developed countries, who have done research in cities with a high rate as City of Mexico, Tijuana and Cali were installed control networks made up of numerous fixed, sophisticated and expensive stations that allow the accumulation of data and decision making in real time.

Generally managing air quality in developing countries is in deficit and characterized by:

1. Lack of basic equipment for monitoring parameters.

2. Breaches or obsolete regulations establishing emission limits for pollutants.

3. No management procedures.

For this reason and to have a control on the process, use the procedures Dr. William Deming, plan, do, check and act.

Planning: Planning Emissions Control (personnel, equipment). Preparation for drawing Emissions Inventory.

Do: Estimated emissions for each source. Inventory integration locally Selection incidence of outbreaks. (Pareto) emission monitoring in selected foci. (> 80%)

Check: Quantification of emissions in the inventory. Processing the results. Compared to the baseline.

Acting Communication to decision makers. Development and implementation of Action Plans. (Point Sources, Local level)
