Effect of RSPM and SPM Pollutants in Ujjain City

The aim of this study was measuring the concentration of various ambient air pollutants in different seasons. During Jan 2013 – December 2013, concentration of Respirable Suspended Particulate Matter (RSPM) and Suspended Particulate Matter (SPM) were collected over successive period of eight hours at three sites. High volume air sampler was used to measure the concentration of Respirable Suspended Particulate Matter (RSPM) and suspended particulate matter (SPM). The results reported pertain to an eight hour successive preliminary air sampling exercise carried out at each of the two select locations i.e. Industrial area and Sensitive area in Ujjain City. Criteria pollutants RSPM and SPM measured are found to have either crossed or on the average of crossing the limits, necessitating the immediate installation of a continuous monitoring and control mechanism. While transport related emissions are the major sources of air contamination, increasing civil construction activities also contribute to particulates. The exponential rise in volume of vehicles, disadvantageous traffic flow pattern, differing driving cycle pattern and human interceptions deserve due attention. The concentrations of some of the pollutants were exceeded the National Ambient Air Quality Standard (NAAQS) at different locations.
