VOCs samples were collected by canisters and were analyzed by GC/MS (Gas Chromatograph / Mass Spectrometer) to realize the concentration and characteristics of VOCs in the atmosphere of science parks. “Surfer”was used to realize correlation among the wind speed and wind direction vs. these air pollutants. Finally, Chemical Mass Balance (CMB) and Positive Matrix Factoriztion method (PMF) to applied to estimate the source contribution in the Science Park. The results of this study show that VOCs emission concentration are between 43.6 and 157 µg/m3 during winter, 34.2 and 196 µg/m3 during spring, 38.5 and 157 µg/m3 during summer, 37.3 and 270 µg/m3 during autumn. Aromatic is the highest pollutants on the concentration in the Science Park for each season, followed by aldehydes and ketones.Toluene is the highest specie of BTEX, followed by xylenes and ethylbenzene. Acetone is highest in spring, methyl ethyl ketone, toluene and benzene are the highest compounds in winter. Ethylbenzene, xylene and ethyl acetate are highest in autumn. The results of CMB analysis show that the pollutants are primarily from organic exhaust reticle most, semiconductor general exhaust, acid and base exhaust reticle. There are four factors in Positive Matrix Factorization method: transportation emission, diesel emissions, oil dissipation, and photovoltaic industry.
