According To Framework Directive 96/62/EC,Preliminary Assessment As A Tool ForAir Quality Monitoring Network DesignIn A Chinese City

In the framework of the Sino-Italian Program in which the Italian Ministry of Environment and Territory is participating, an Air Quality Monitoring System in the City of Suzhou (China) was implemented by the Institute for Atmospheric Pollution of the Italian National Research Council (CNR-IIA). As stated in Framework Directive 96/62/EC, preliminary assessment of air quality is a very important step in the identification of sites for fixed monitoring stations. To that end, 100 saturation stations, equipped with passive samplers for sulphur dioxide, nitrogen oxides, ozone, ammonia and BTX (benzene, toluene and xylene), were set up. The concentration values of these pollutants, coming from three campaigns carried out in Suzhou, were represented and explored by using the Arcview 8.2 software with Geostatistical Analyst and Spatial Analyst extensions. The interpolation was carried out using the two most important interpolation models (Inverse Distance Weighting and Ordinary Kriging). With reference to each campaign, pollution maps related to each interpolation model and to each pollutant were produced. Finally, a map with the definitive siting of the fixed monitoring stations was produced.
