Case Studies on Air Quality Indexing Systems for Nashik City

The Air Quality Index (AQI) is used to report ambient air quality status on day to day basis. The number indices have been developed using different criteria pollutants but no. index is available which takes into consideration all the pollutants. Further these, indices are not comparable in absolute terms in developing countries like India such an index mainly used for academic purpose. AQI depends upon a number of parameters which needs to be clearly defined critically evaluated. Other wise this may be misleading. Ambient air quality monitoring has been conducted at four sampling location around Nashik city, Ambad Industry, Sinner Industry and Satpur industry. The data obtained at one of the sampling location have been compared with standard data. The observation indicates that there is a marked safety in the computation methodology. The observation also indicates that the fugative emission have significant impact on the ambient air quality.
