中文摘要	基於區域性與跨洲際大氣污染(包含酸性污染物、亞洲沙塵、生質燃燒、大氣汞等)傳送問題之釐清，以及我國背景大氣基線資料之建立，環保署於中部鹿林山建構具國際水準之空氣品質背景測站，於2006年4月13日正式啟用。本計畫整合降水化學、微量氣體、大氣氣膠、大氣汞、大氣輻射及氣膠輻射等主要領域專長研究人員進行鹿林山背景測站相關儀器功能測試、維護及數據資料分析，建置長期資料庫，並計算資料可用率，鹿林山輻射儀器及氣象類別儀器的資料可用率都高於90 %。另建立我國空氣品質長期基線資料，量化區域及境外傳輸對我國之影響程度。本計畫執行期間，定期及機動維護派員前往鹿林山背景站共55次。 2022年1月至2022年10月計畫執行期間資料顯示，CO平均為107.2 ppb，O3平均為34.9 ppb，PM2.5平均為4.5 μg m-3、雨水pH值平均為5.55、氣態元素汞(GEM)平均濃度為1.37 ng m-3、氣態二價汞(RGM)平均濃度為11.0 pg m-3、顆粒態汞(pHg)平均濃度為22.3 pg m-3。計畫期間各污染物月平均濃度變化趨勢顯示，鹿林山春季受境外移入之大氣污染物影響顯著，藉由氣流軌跡分析、污染物成分分析可確定高污染事件與境外人為污染物有關。估算鹿林山CO和PM2.5的背景值分別為124.5 ppb及4.0 μg m-3。持續推動我國與美國環保署、太空總署、海洋大氣總署、日本及歐盟國家合作，進行技術交流與資料交換。積極參與國際合作，例如七海計畫(7-SEAS)國際實驗及與日本富士山監測站區域合作等，進行實質監測、資料交換、技術交流、參與會議，並爭取會議主辦權。鹿林山背景站目前已是許多全球觀測網的一員，例如美國大氣汞監測網AMNet、NASA/AERONET，NOAA/GMD/ CCGG及全球氣膠監測網。更多資訊可參考鹿林山大氣背景站中英文網頁。

摘要	In order to clarify the intercontinental and regional transport of air pollutants (for instance, acid pollutants, Asian dust, biomass burning and mercury), and to collect the atmospheric baseline data, the Lulin Atmospheric Background Station (LABS, 2862 m MSL), located at Mt. Lulin in central Taiwan, has been operated since 13 April 2006. This project integrates the researchers in the fields of precipitation chemistry, gas chemistry, aerosol chemistry, atmospheric mercury and radiation to test and maintain the instruments, conduct data analysis and construct long-term database. Up to now, total on-site maintenances (includes regular and mobile) are 55 times. The data acquisition rate for aerosols, radiation and meteorological instruments are greater than 90 %, whereas atmospheric mercury and trace gases instruments shows lower rates, due to their complexities. During the project conducting period (2022/1-2021/10), the average concentrations of CO, O3 and PM2.5 are about 107.2 ppb, 34.9 ppb and 4.5 μg m-3, respectively. The average pH value of precipitation is 5.55. The average concentrations of mercury such as GEM, RGM and PHg are about 1.37 ng m-3, 11.0 pg m-3 and 22.3 pg m-3, respectively. Monthly variation shows the high concentration of pollutants generally occurred during spring time, especially in March. Integrating trajectory analysis and chemical component analysis, we suggest the high concentration events are most likely associated with the biomass burning from SE Asia. The atmospheric background values for CO and PM2.5 in Lulin are estimated to be about 124.5 ppb and 4.0 μg m-3. In addition, we have established intensive international collaborations with USEPA, NOAA, NASA, Japan, and EU countries. We have also participated international experiments or campaigns including 7-SEAS, and Japan Mt. Fuji Project. The LABS is now part of global networks, for instance, American Mercury network/AMNet, NASA/AERONET, NOAA/GMD/CCGG sampling network.

摘要

In order to clarify the intercontinental and regional transport of air pollutants (for instance, acid pollutants, Asian dust, biomass burning and mercury), and to collect the atmospheric baseline data, the Lulin Atmospheric Background Station (LABS, 2862 m MSL), located at Mt. Lulin in central Taiwan, has been operated since 13 April 2006. This project integrates the researchers in the fields of precipitation chemistry, gas chemistry, aerosol chemistry, atmospheric mercury and radiation to test and maintain the instruments, conduct data analysis and construct long-term database. Up to now, total on-site maintenances (includes regular and mobile) are 55 times. The data acquisition rate for aerosols, radiation and meteorological instruments are greater than 90 %, whereas atmospheric mercury and trace gases instruments shows lower rates, due to their complexities. During the project conducting period (2022/1-2021/10), the average concentrations of CO, O3 and PM2.5 are about 107.2 ppb, 34.9 ppb and 4.5 μg m-3, respectively. The average pH value of precipitation is 5.55. The average concentrations of mercury such as GEM, RGM and PHg are about 1.37 ng m-3, 11.0 pg m-3 and 22.3 pg m-3, respectively. Monthly variation shows the high concentration of pollutants generally occurred during spring time, especially in March. Integrating trajectory analysis and chemical component analysis, we suggest the high concentration events are most likely associated with the biomass burning from SE Asia. The atmospheric background values for CO and PM2.5 in Lulin are estimated to be about 124.5 ppb and 4.0 μg m-3. In addition, we have established intensive international collaborations with USEPA, NOAA, NASA, Japan, and EU countries. We have also participated international experiments or campaigns including 7-SEAS, and Japan Mt. Fuji Project. The LABS is now part of global networks, for instance, American Mercury network/AMNet, NASA/AERONET, NOAA/GMD/CCGG sampling network.
