ABSTRACT

Introduction: Mexico City produces approximately five million tons of air pollutants each year, among them, sulphur dioxide (SO2), nitrogen dioxide (NO2), aromatic hydrocarbons, such as benzene, these last two, precursors of ozone (O3), and a great variety of particles of diverse size, nature and origin. Some of them, with less than 10µg of aerodinamical diameter (PM10) remain suspended in the air and may be inhaled and deposited inside the airways. Air pollution and health: Several epidemiological studies suggest that human exposition to high levels of O3 and PM10 are associated with the development of respiratory diseases. Other studies suggest an association between exposure to PM10 and mortality. The purpose of this study was to revise the relation between air pollution and respiratory morbidity and mortality, and the tendency of the main pollutants in the air of the southern Mexico City Metropolitan Area. Air pollution in Mexico City: The Automatic Air Monitoring Net (RAMA) has shown that the air pollutant O3 is persistently elevated in Mexico City. PM10 also showed high levels and taking into account that PM10 represent a high risk to human health we recommend to launch preventive programs, to control of garbage management, the emission of industrial and motor vehicle pollutants and also the prevention of forest fires.
