摘要: 本期研究将以改良的采样方法并结合过去五年的计画执行经验,在新庄、中山及竹东三个空气品质监测站(air quality monitoring stations, AQMS)进行采样,采样结果也将与AQMS的各种气象及污染物的监测值进行比对分析。滤纸样本中微粒的水溶性离子成分将由本研究以IC进行分析,金属成分则由本计画合作单位中央研究院环境变迁中心利用ICP-MS方法分进行析。本研究也将利用正矩阵因子法(Positive Matrix Factorization model , PMF)推估微粒的来源。此外,本研究也会探讨不同湿度及微粒负荷量对WINS冲击器及VSCC旋风器分径效果造成的影响,以找出最适合国内的粒径筛分装置。
为了筛选出国内最适合的奈米微粒数目浓度与细微粒质量浓度即时量测技术,本研究将分别针对扫描式微粒电移动度分析仪(Scanning Mobility Particle Sizer, SMPS)及滤纸动态量测系统(Filter Dynamic Measurement System, FDMS)的量测结果进行评估。关于SMPS,本研究将针对其对于不规则形状微粒的量测结果作探讨,FDMS方面则会以环检所公告之标准手动采样方法和其测值进行比对。
This year, the present study will use the modified sampling method and incorporate with the experience from previous projects to conduct the ambient aerosol samplings at Xinzhuang, Zhongshan and Zhudong air quality monitoring stations (AQMS). For further understanding of the interaction between different pollutants and meteorological variables, the sampling results will compare with the real-time meteorological and pollution data obtained from the AQMS. All particle samples will be analyzed for water-soluble compounds using the Ion Chromatography (IC), and will be also distributed to Dr. Shiu of Research Center of Environmental Changes to conduct the metal analysis by using the LA-ICP-MS or ICP-MS. Finally, the Positive Matrix Factorization model (PMF) will be utilized to predict the particulate sources. Beside the sampling work, the effects of ambient relative humidity and loaded mass on the cutoff characteristics of WINS and VSCC will also be evaluated hoping to find out a size-selective inlet which is suitable in our country.
In order to select the suitable methods for real-time measurement of nanoparticles number concentration distribution and fine particle mass concentration in our country, the performance of Scanning Mobility Particle Sizer (SMPS) and filter dynamic measurement system (FDMS) will also be evaluated. For the SMPS, the investigation will focus on the number size distribution of agglomerate particles. For the FDMS, its PM2.5 real-time monitoring mass concentration will be compared with the results obtained from a collocated WINS PM2.5 sampler whose sampling procedure follows the standard manual sampling method proposed by the National Institute of Environmental Analysis (NIEA).
