摘要

近年來，宜蘭空品區的空氣污染指標(PSI)呈現逐年增加趨勢。本文以宜蘭與冬山兩個測站空氣污染物監測值的月平均值為依據，分析2002年至2007年8月間，污染物月平均值變化情況、懸浮微粒(PM10)與臭氧(O3)濃度的時間變化趨勢、以及兩測站PM10與O3濃度變化相關性。數據分析呈現宜蘭測站僅O3監測數據高於冬山測站，宜蘭測站PM10濃度逐漸增加、O3呈現下降趨勢，冬山測站監測數據趨勢與宜蘭測站相反，兩測站間PM10與O3比較結果具有相當程度的正相關性。

In recent years, pollutant standard index (PSI) of I-Lan air quality area is getting worse and worse. There are only two monitoring stations, I-Lan and Ton-San, in this air quality area. Monthly average concentrations of monitoring air pollutants were used in this study to analyze the time variations of air pollutants, especially suspended particles (PM10) and ozone. Preliminary results of this study show ozone concentration of I-Lan monitoring station is higher than that of Ton-San, however, the month concentration of PM10 increased for I-Lan station, but that of ozone decreased for the same station. Positive correlation results are obtained for concentrations of PM10 and O3 between those two monitoring stations.
