摘要: | 在本期计画中,除了持续至新庄、中山及竹东三个空气品质监测站(air quality monitoring stations, AQMS)进行手动采样之外,本研究也将利用即时量测仪对微粒成分做即时监测。滤纸样本由本研究团队进行质量及水溶性离子浓度分析,样本中之金属成分则由本计画合作单位中央研究院环境变迁中心进行分析。本研究也会利用正矩阵因子法(Positive Matrix Factorization model, PMF)来探讨微粒排放污染源。AQMS监测值普遍高估手动采样结果的原因本研究也将详加探究。 细微粒量测技术方面,本期计画将持续探讨锥形震荡微量天秤与滤纸动态量测系统(trapped element oscillating microbalance with filter dynamic measurement system, TEOM-FDMS)于国内大气环境的适用性,并制定量测标准操作程序。而在奈米微粒量测研究方面,本期计画将着重在新兴奈米产品于使用过程中造成奈米物质逸散等问题进行定性及定量的研究。 关于雷射剥蚀感应偶合电浆质谱仪(LA-ICP-MS)之量测技术开发方面,本研究也将持续于实验室内进行标准品校正。此外,本研究也将至雪山隧道以微孔均匀沉积冲击器(micro-orifice uniform deposit impactor, MOUDI)采集微粒样本,供LA-ICP-MS进行大气样本实测。 In this project, in addition to continuing samplings at Sinjhuang, Jhongshan and Judong air quality monitoring stations (AQMS), collocated real-time measurement instruments will also be used for aerosol compositions monitoring. Filter samples will be analyzed for mass and water-soluble ions concentrations by our team group, while metal composition of the sample will be analyzed by our project cooperator of Research Center of Environmental Changes. The Positive Matrix Factorization model (PMF) will be utilized for characterization of particulate sources. Finally, the major reason why the PM2.5 monitoring data from AQMS are normally higher than the manual sampling results will be also investigated. For the fine particle measurement technique, this project will continue to evaluate the suitability of the trapped element oscillating microbalance with filter dynamic measurement system (TEOM-FDMS) used in the atmospheric environment of our country. The standard operation procedure of the TEOM-FDMS will also be developed. For the nanoparticle measurement study, this project will focus on characterizing and quantifying the nanomaterial released during the life cycle of the emerging nano-products. For the development of measurement technique by using the laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), this project will continue to calibrate the LA-ICP-MS by standard samples in the laboratory. After that, ambient aerosol samples will be collected by the micro-orifice uniform deposit impactor (MOUDI) at Syueshan highway tunnel for testing the measurement performance of the LA-ICP-MS. |
