Paper Title
Measurement of Ambient PM10 Concentration during Winter Season at Faridabad

Abstract
Air pollution is one of the major problems in India. In winter, the concentration of air pollutants increases due to less dispersion of pollutants and stable atmosphere. PM10 is one of the most harmful pollutants and its concentration exceeds NAAQS permissible value (100µg/m3) in Delhi and NCR. In our study, the ambient air concentration of PM10 in two different industrial sites was monitored in the month of September, October, November and December. The two study areas were brick kiln in Nacholi village and gas based thermal power plant in Mujedi village located in Faridabad. Monitoring was done for 24hours with Respirable Dust Sampler and analysis was done by Gravimetric Method in each month at two sites. The average concentration of PM10 was found to be higher in brick kiln (380µg/m3) than thermal power plant (261µg/m3). In both the study areas, the average concentration exceeded the NAAQS value by 3.8 times and 2.6 times in brick kiln and thermal power plant respectively. Higher concentration of PM10 from brick kiln is attributed to incomplete combustion of fuels and large amount of dust during its operation and transportation of bricks. The maximum concentration was found in the month of October at both the sites which may be due to Diwali festival and stubble burning. There is an immediate need to adopt air pollution control strategies especially in winter season to abate its harmful effects on environment and human health.
