Abstract

The present study investigated the aerosol concentration of highly industrialized city of Jamshedpur, Jharkhand, India. To assess the aerosol load (PM10) in ambient air eight monitoring stations were selected in the Jamshedpur city. A total of 24 airborne samples were collected on G/FA filter papers usingRespirable dust sampler 460 NL (Envirotech, India). For every location 24 hour average values were taken. Samples were collected with different characteristic locations viz., industrial, commercial and residential area.The average values of PM10 ranged from 60-92 &g/m3for all the locations. The highest concentration of PM10 was recorded at Burma mines i.e., 92 &g/m3 (Industrial area) and the
lowest at Nildih i.e., 60 &g/m3 (residential area). The other locations showing higher concentration of PM10 were Jugsalai ,Sakchi and Adityapuri. High PM10 load may be due to location of the city, mining activities and type of operational units of the steel plant, large, medium and small scale industries dealing in steel, iron, cement, thermal power, motors road transport and resuspended dust in industrial and commercial locations.
