Abstract

Major factors responsible for variation occurring in ambient particulate levels in urban areas are, growing of a number of stationary and mobile sources of particulate matter and meteorological parameters. The work presented here focused on the effect of meteorological parameters on ambient PM levels and the relationship of those levels at industrial complexes with their components at receptor ambient sites. Seven monitoring stations were identified in the study area for the measurement of PM10 levels during 2005-06. Of the seven sampling stations three were located in three major industrial complexes in the study area, and the remaining four were taken as receptor zones of particulate matter. All receptor-PM10 values showed moderate correlation with specific industrial complexes. Most of the receptors showed PM10 levels exceeding Indian NAAQS for residential areas. An inverse relationship between PM10 levels and meteorological parameters has been obtained.

Highlights

Large urban centers of developing countries face difficult environmental problems arising from the growth of industrial complexes.They are receiving significant environmental damage due to the air pollutants (Bohm and Saldiva, 2000)
The presented study focused on investigating dispersion patterns of ambient PM10 in urban environment of Raipur, Chhattisgarh in India, factors that affect it as a result of industrial complexes around the city, and on the variation in local meteorological parameters
Sampling design The dispersion and transport of suspended particulate matter (SPM) in the atmosphere, which is of prime concern for air pollution researchers, are affected by meteorological parameters

Summary

Introduction

Large urban centers of developing countries face difficult environmental problems arising from the growth of industrial complexes.They are receiving significant environmental damage due to the air pollutants (Bohm and Saldiva, 2000). The presented study focused on investigating dispersion patterns of ambient PM10 in urban environment of Raipur, Chhattisgarh in India, factors that affect it as a result of industrial complexes around the city, and on the variation in local meteorological parameters. Sampling design The dispersion and transport of suspended particulate matter (SPM) in the atmosphere, which is of prime concern for air pollution researchers, are affected by meteorological parameters (wind speed, relative humidity, wind direction and temperature).
