Assessment of ambient air quality in different areas of cement industry, Chandrapur, Maharashtra, India

Abstract

The term air quality means the state of the air around us. Ambient air quality refers to the quality of outdoor air in our surrounding environment. It is typically measured near ground level, away from direct source of pollution. The paper present air pollutants (such as particulate matter 2.5, particulate matter 10, sulphur dioxide and oxide of nitrogen) emitted from cement plant, chandrapur, maharashtra. This study was undertaken to investigate the air quality around the cement plant within 5 km radius. The air temperature, relative humidity, wind speed and predominant wind direction were studied for the sampling days. Data for all four air pollutants were collected for a study period at four different locations (Awarpur, Palgaon, Nanda and Naokari). Results indicate that both particulate matter (PM2.5 and PM10) and gaseous pollutants (SO2 and NO2) are within the permissible limit prescribed for industrial, residential and rural uses by CPCB, New Delhi. The average value of concentration of all the air pollutants under the permissible limits due to industry have installed air trapping devices which control air pollution and helps to minimize the dust in the surrounding area.
