  • 摘要:Like many big urban centers, Mendoza, a city of about 900,000 inhabitants, has
    increasing air pollution mostly from mobile sources. To asses on its air quality, two main
    strategies have been developed: the setup of a network of monitoring stations and the
    development of a comprehensive model. Continuous monitoring and daily measurements of
    main pollutants had been performed since more than 10 years, at different sites, combined
    with several measuring campaigns. On the other side, a model, based on a geographical
    information system has been developed to evaluate the air quality derived from stationary
    and mobile sources. Once the model has been calibrated with the given measurements, the
    system is then used to test the compliance to local standard air quality, or to study the
    environmental impact of new industries or to determine the changing conditions when vehicle
    circulation is increased. This allows characterizing areas with potential increase in air
    pollution or improvement in air quality. It is also possible to compute different scenarios by
    changing basic information as traffic flow, or stack emission rates
