Mobile Source Emissions of Criteria Pollutants in Ecologically Sensitive Areas

Siby John, Umesh Sharma


Air pollution is one of the most serious and rapidly growing problems in the urban centres. Ecologically Sensitive Area (ESA) is a type of designation for an area which needs special protection because of its functional, ecological and historical value. In this paper, the air quality of an ecologically sensitive area of Chandigarh vis-à-vis the mobile sources are presented. The concentration of the criteria pollutants is found to be exceeding the permissible limits in the study area. The concentration of the pollutants is largely due to the increased vehicular population. The regression analysis using SPSS10.0, correlating traffic characteristics and pollutants concentration has been used as an ecological and transport management tool.
