dc.description.abstractCarbonaceous aerosols are an important constituent of the aerosols and may be broadly divided in two parts, viz. organic carbon (OC) and elemental carbon (EC). Carbonaceous aerosol concentration was determined at an urban residential site in Agra. Sampling of fine particles (PM2.5) was carried out during May to August 2011. The concentration of PM2.5 at urban residential site was 55.3±17.4 μg m-3, which is within the prescribed limits. OC varied from 7.6 to 37.5 µg m-3, with an average of 18.2±6.4 µg m-3; EC ranged 1.2 - 9.4 with an average of 3.2±1.6 µg m-3; while total carbonaceous aerosols (TCA) varied from 13.6 to 69.4 µg m-3. On an average, TCA accounted for 64.9% of PM2.5 mass implying that carbonaceous aerosol is a significant component of PM2.5. OC/EC ratio at the site was in the range of 3.5 - 11.9. OC/EC ratio indicates the contribution of both the primary and secondary sources. en_US
