摘要：

According to geographical characteristics and air quality conditions, the Taiwan Environmental Protection Agency has divided the island into 7 air quality regions (AQRs) including Northern, Chu-Miao, Central, Yun-Chia-Nan, Kao-Pinge, I-lan and Hwa-Tung AQRs. The grey relational grade (GRG) of all AQRs and nationwide grade were calculated to comprehend the level of contamination. Then the grey model GM (0, N) was used to evaluate the effects of 5 primary contaminants on air quality. The results indicated that the ranking of air quality for the 7 AQRs from the best to the worst were as follows: Hwa-Tung > I-lan > Chu-Miao > Northern > Yun-Chia-Nan > Central > Kao-Ping. The 5 most common contaminants from the greatest to the least were as follows: CO > SO2 > NO > O-3 > PM10.
