Abstract

Seismic Information on air quality in urban areas represents an important objective to raise awareness and participation of citizens towards those measures aimed at containing and reducing vehicular traffic. For several years at the international level, evaluation procedures have been adopted by indices. One of the first synthetic indices, adopted by the United States Environmental Protection Agency (US-EPA), have established an exchange of information from networks and individual stations measuring ambient air pollution in member states, the use of a single index has not yet been defined. Through the use of Air Quality Index (AQI) it was possible to synthesize in a single daily value, concentrations of major pollutants in urban areas (NO2, O3, CO, SO2, PM10, and PM2.5) for the entire period. For the calculation procedure of the AQI, the data concentrations were provided by Municipal Ecology and Environment Office. The data relates to three monitoring stations, whose locations have not changed over the years. This also made it possible to evaluate the change in frequency of AQI agglomerations where the monitoring units have been ranked in six levels of pollution; each level has been associated with a particular coloring allowing this information to be more intuitive. Lastly, it was possible to reach the air quality assessment in urban environment from the frequency variations of each level derived from the present years. The aim of this Assessment is to increase Awareness of daily levels of air pollution is important, especially for those suffering from illnesses caused by exposure to air pollution. To study about Air Quality Index the region of Nashik city, Maharashtra state is considered.
