碩士 === 逢甲大學 === 環境工程與科學所 === 100 === Because the awareness of improving surrounding environment quality of life and emphasis on health risks, therefore, the emissions fingerprint data of the manufacturers and the atmospheric volatile organic compounds of two processing export zones in Taichung City were carried out in the study. In addition, the chemical mass balance model (CMB) was used to estimate the contributions of ambient VOCs in the export processing zones. The differences in environment and air pollution were explored completely. Finally, these results were used to develop their improvement strategies. The analysis results of ambient VOCs in two export processing zones show that of the composition, concentration and distribution of VOCs during difference season will affect by prevailing wind direction and wind speed clearly. High percentages of alkanes, aromatics, aldehydes, and alcohols occurred in the ambient air of Tan-zi processing export zone; and high percentages of alkanes and aldehydes occurred in Chung-kang processing export zone. The relationship between the concentrations of VOCs with the positions of major emission sources was clearly. The simulation results by CMB shown that factories PM, BA, and CA and factories CI, JS, SP, and EL were major contributions for ambient VOCs in the Tan-zi processing export zone and in the Chung-kang processing export zone, respectively The difference of existing environment between two export processing zones mainly associated with factories density, road width, and wind speed strength.
