Exceedance Level of Air Pollutants in an Urban Area as a Tool for Designing Air Purifiers

The air pollution exceedance status of an urban area has been studied for three different location for six
different air pollutants such as Sulphur dioxide (SO2), Oxides of nitrogen (NOx), by Wet chemical method
(West & Gaeke Method & Jacob & Hochheiser Method), Heavy Metal (Pb) by ICP-OES (Perkin Elmer),
and PAHs [benzo(a)anthracene] & Fluoranthene by using GC (Perkin Elmer), and Particulate Matter
(SPM, PM10,) by Federal Reference Method (Rupprecht & Patashnick Co.In) for one annual cyclic season
along with meteorological data (wind speed and direction). Seasonally variation of air pollution
parameters with respect to month throughout one year was studies and it has been observed that a suitable
control over few pollutants is needed in all the land uses. The air purification system is hence evaluated for
varying land uses. These results can be effectively used as tool for designing of air purification system.
