The high PM2.5 level is the root of different type’s health problems in residential houses and neighbourhood poor peoples. 90 samples of PM2.5, across the two seasons namely summer and winter, were collected on quartz fiber filters in each three different residential areas (three houses each in residential colony, near roadside, and in industrial zone) monitoring sites of Durg district, Chhattisgarh, India to determine their concentration levels and to investigate comparison with those reported in National ambient air quality standards (NAAQS). The sampled filters were analysed for mass gravimetrically using six-digit electronic balance. The mass concentrations of PM2.5 has shown following trend in summer: roadside houses (188.95 ± 58.2& Copyright@ International Science Community Association
