The local emission profiles of various industries were established. Ninety plants with 3 samples for each plant and totally 270 samples were investigated in this study. In addition, 9 ambient air samples were used for the source apportionment study by using Chemical Mass Balance (CMB 8.2) model. The results show that the total volatile organic compounds (TVOCs) concentrations were 23.8 ~ 448.6 ppb in the atmosphere. The concentrations are higher for the sites near emission sources. The simulation results of CMB8.2 model show that the main VOCs sources were the mobile sources. The contribution is 5.39 ~ 43.2%. The contributions of chemical products manufacturing, electronic components manufacturing, machinery and equipment manufacturing, and computers, electronic products and photochemical manufacturing are 10.5 ~ 46.6, 5.50 ~ 43.2, 23.7 ~ 34.8, and 0 ~ 33.2%, respectively. It shows that the simulation results con not meet the requirements of the estimated value of 80 ~ 120%. Selecting the source profiles of the industrial plants near the receptors for CMB model can improve the estimation.
