Monitoring and assessment of particulate matter and poly aromatic hydrocarbons (PAHs) around a petroleum refinery.
Ambient air particulates, both total and respirable fraction collected at number of locations around a petroleum refinery in west coast of India, having crude processing capacity of 12.5 million metric tones per annum, were analyzed and associated PAH concentrations were determined. PAHs in SPM near the refinery varied from 12% to 45% while in urban cities, it varied from 0.45% to 0.65%. The percentage PAHs in RSPM near the refinery varied from 6% to 20% while in urban cities, it varied from 0.5% to 1.45%. The refinery contribution of 11.5%-44.3% PAHs to ambient TSP and 5.5%-18.5% PAHs to ambient RSPM was observed. Non-respirable fraction of ambient TSP near refinery contributed upto 25% PAHs.
