- 中文摘要: 本研究探討大氣環境中對半揮發性多環芳香族碳氫化合物在氣相與微粒相間分佈之影響。本研究首先建立以PM10μ?基礎分佈模式,log { A(PM10)/F'}=m/T+b ,其中A及F'代表氣相與PM10μ微粒上多環芳香族碳氫化合物之含 量,T?大氣?度,m及b?常數,而後進一研究在三個?濕度條件下之分佈模式,分??相對濕度50%-70% , 70 %-80%,以及80%-95%,並探討濕度對分佈現象影響之因素。結果顯示在大於50%高濕度環境中三個不同濕度條 件下之分佈模式在統計上並無差異。本研究期間在台北市地區進行大氣環境多環芳香族氣相與微粒相之採樣,以及大氣溫度及濕度之測定,並以GC-MS進行多環芳香族成分之分析與確認。
- 英文摘要: The partitioning model between gaseous and PM10μ particulate phases for semi-volatile PAHs, Fluoranthene and Pyrene was investigated in urban atmosphere with high humidity. The partitioning model is in the form of log { A *(PM10)/F'} = m/T + b, where the A and F' stand for the PAH amount in gas and particulate phases, respectively, jfis the ambient temperature, and m and b are constants. The partitioning model based on the particulate phase PM10μ has not been done before. The influence of humidity on the partitioning model for high humidity atmosphere, which is usually greater than 50%, is then investigated. It was shown that there was no significant difference on the partitioning models among three groups with different relative levels of humidity according to statistical analysis. They were relative humidity levels of 50% to 70%, 70% to 80%, and 80% to 95%. The sampling experiments of gaseous and particulate PAHs were carried by using PUF plugs and PM 10μ sampler in downtown Taipei city from June, 1988, to May, 1990. Also, ambient temperature and relative humidity were measured. The samples were analyzed by GC/MS for the PAH substances.
