This study describes continuous monitoring of the volatile organic air pollutants, acetone and toluene, in Hsinchu Science Park (HSP) during an occurrence of inclement weather, i.e., a typhoon. Using a lab-designed sampling system coupled with a continuous automated GC-MS analysis system, a total of 53 polar and nonpolar compounds were identified and quantified. The concentration of polar compounds dropped sharply from 41.4 ppbv before the typhoon to the stage of no detection during the storm, but rose again after the typhoon. The amount of nonpolar compounds remained unaffected during the storm. The polar compounds were more affected by both the rainfall and wind than were the nonpolar compounds. The severity of air pollution strongly correlates with the concentration of acetone released into the atmosphere by a wastewater treatment facility. The system used in this study has been proved reliable while working in inclement weather condition; in addition, the results can probably be applied in the monitoring of the environment during the typhoon season in high-tech research areas.
本研究描述了在新竹科学园区（HSP）出现恶劣天气（即台风）期间，对挥发性有机空气污染物丙酮和甲苯进行的连续监测。使用实验室设计的采样系统与连续自动气相色谱 - 质谱分析系统相结合，共鉴定并定量了53种极性和非极性化合物。极性化合物的浓度在台风来临前从41.4 ppbv急剧下降至风暴期间未检测到的阶段，但在台风过后又再次上升。非极性化合物的量在风暴期间保持不变。与非极性化合物相比，极性化合物受降雨和风的影响更大。空气污染的严重程度与废水处理设施排放到大气中的丙酮浓度密切相关。本研究中使用的系统已被证明在恶劣天气条件下工作时可靠；此外，研究结果可能适用于高科技研究区域台风季节的环境监测。
