ZHANG Ai-dong1,WANG Xiao-yan2,XIU Guang-li3(1.2Environmental Monitoring Station of Zhabei in Shanghai,Shanghai 200072,China;3.East China University of Science and Technology,Shanghai 200237,China)  
Volatile organic compounds(VOCs) in ambient air near traffic road was monitored continuously for six days in winter in Shanghai.28 kinds of VOCs was qualitatively identified by GC-MS,and aromatic hydrocarbon and alkane occupied 32% and 25% respectively.8 kinds of VOCs were belong to priority HAPs regulated by U.S.A.Quantitative results by GC-FID showed that BTEX is the main part of aromatic VOCs,and toluene has the largest concentration.The good correlation of BTEX to CO and NO2 implied that the source of BTEX is associated with vehicle exhaust emission,and they were all found to be dependent of wind speed and vehicle volume.
