Distribution, Sources and Fate of Polycyclic Aromatic Hydrocarbons in Air, Dust and Sediment of Central India

Polycyclic aromatic hydrocarbons (PAHs) are a group of > 100 carcinogenic compunds emitted during combustion of fuels and other materials. In this work, distribution, sources and fate of twelve PAHs: phenanthrene (Phe), anthracene (Ant), fluoranthene (Fla), pyrene (Pyr), benz[a]anthracene (Baa), chrysene (Cry), benzo[b]fluoranthene (Bbf), benzo[k]fluoranthene (Bkf), benzo[a]pyrene (Bap), dibenz[a,h]anthracene (Dba), benzo[ghi]perylene (Bgh) and indeno[1,2,3-cd]pyrene (Ind) in the air, road dust and sediment of the most industrilized area of central India are described. The PAHs contents in the ambient air (n = 24) during year 2007-08 were ranged from 0.04 – 0.17 μg/m3 with mean value of 0.09±0.02 μg/m3, respectively. The highest mass concentration was observed in the winter season, December – January. The concentration of the PAHs in the PM10, road dust (n = 8) and sediment (n = 10) of Raipur city was ranged from 238 – 467, 8.7 – 21.7 and 6.8 – 10.9 mg/kg with mean value of 342, 12.7 and 9.2 mg/kg. The vehicular emissions and coal/biomass comustion were apportioned as main sources for relase of the PAHs in the environment. The spatial (residential, commercial and industrial), seasonal (summer, rainy, autumn and winter) and temporal (2007-2015) variations of the PAHs in the environment of the central India are discussed.
