Abstract
Air pollution is dispersion of the particulates, biological molecules, or other harmful materials into the Earth’s atmosphere. Industrialization and urbanization are the two major causes of deteriorating air quality of the major cities in Tamil Nadu, India. Coimbatore is the second and most important commercial and industrial city in India. These industrial activities can add significant levels of heavy metals in the atmosphere. So, regular surveillance and consistent monitoring and modelling of the city would be much imperative. To evaluate the ambient air quality in Coimbatore city the pollutants such as PM10, Suspended Particulate Matter (SPM) and Heavy metals (Cd, Cr, Cu, Pb, Fe, Ni and Zn) were monitored at four locations of the city in this project. The concentration of PM10, SPM and seven heavy metals in the ambient air were estimated and the contributions of various sources were evaluated. The concentration of PM10 and SPM were found to be within the permissible limit. The aim of the project is to develop models, the concentration details of PM10 (Particulate mass). The quality analyzed parameter were compared with the values given by National Ambient Air Quality Standards (NAAQS) Nearly 8 Places in Coimbatore City.
