Taipei--The air quality was poor in central and southern Taiwan Tuesday but northern, eastern Taiwan and the offshore islands were seeing moderate to good quality air, according to the Environmental Protection Administration's Taiwan Air Quality Monitoring Network.

For Wednesday, only the air quality in central Taiwan is expected to flash orange (unhealthy for sensitive groups) while that in the rest of the country is likely to be yellow (moderate) to green (good), according to the network (http://taqm.epa.gov.tw/taqm/en/AqiForecast.aspx).

On both Tuesday and Wednesday, the eastern counties of Yilan, Hualien and Taitung enjoy good quality air while northern Taiwan, including Hsinchu and Miaoli Counties, and the offshore islands of Kinmen, Matsu and Penghu have moderate air quality.

Central Taiwan and counties to the south, such as Yunlin, Chiayi and Tainan, had level-orange air whereas people living in Kaohsiung City and Pingtung County had to endure air that was unhealthy for the general public (red).

Green represents "good" air quality, with a pollutant reading of less than 50; yellow indicates "moderate" at 50-100; orange means "unhealthy for sensitive groups" with a reading of 101-150; red indicates "unhealthy" with a range of 151-200; purple signifies "very unhealthy" with a level of 201-300; maroon represents "hazardous" with an reading of 301-500.
