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.
对印度西海岸一家年原油加工能力为1250万吨的炼油厂周围多个地点采集的环境空气颗粒物（包括总颗粒物和可吸入颗粒物部分）进行了分析，并测定了相关多环芳烃（PAH）的浓度。炼油厂附近悬浮颗粒物（SPM）中的多环芳烃含量在12%至45%之间，而在城市中，该含量在0.45%至0.65%之间。炼油厂附近可吸入悬浮颗粒物（RSPM）中的多环芳烃百分比在6%至20%之间，而在城市中，该百分比在0.5%至1.45%之间。观察到炼油厂对环境总悬浮颗粒物（TSP）中多环芳烃的贡献率为11.5% - 44.3%，对环境可吸入悬浮颗粒物中多环芳烃的贡献率为5.5% - 18.5%。炼油厂附近环境总悬浮颗粒物的不可吸入部分中多环芳烃含量高达25%。
