| Abstract: | Votatile Organic Compounds(VOCs)sampling was conducted at an interval of 2-3 hours from7:00-23:00(five times per day)from 19 to 26 August,2009 at Tianjin Meteorology Bureau Tower.103 spices compounds was detected and quantitated,including alkanes,alkenes,aromatics,halogenated NMOCs and others,and alkanes was the mainest pollution compounds.Possible sources were examined using EPA PMF model.Five major factors were chosen according to the sampling analysis.Sources include,motor vehicle exhaust,gasoline evaporative emission,industry emission,combustion emission and biogenic emission.The contribution rates of five sources were 25.09%,26.92%,23.59%,13.60% and 10.80% respectively.Mobile source include motor vehicle exhaust and gasoline evaporative emission were the most significant contributor to VOCs,which was affected by the morning and night rush hour. |
