Taipei--Taiwan's air quality ranged from fair to good on Saturday, with only two monitoring stations across the country signaling air quality that was unhealthy for sensitive groups, according to the Environmental Protection Administration's Taiwan Air Quality Monitoring Network.
As of 8 p.m. Saturday, the air quality in New Taipei's Wanli and Linkou districts flashed orange, indicating unhealthy air for sensitive groups such as small children, the elderly and people with chronic diseases, according to data provided by the network (http://taqm.epa.gov.tw/taqm/en/).
For the rest of the country, the air quality was either fair (yellow) or good (green).
On Sunday, the air quality is expected to flash orange in parts of central Taiwan, including Yunlin, Chiayi and Tainan, while the air quality throughout eastern Taiwan (in Yilan, Hualien and Taitung), and the offshore Kinmen and Penghu islands is forecast to remain good.
In northern Taiwan, including Hsinchu and Miaoli, as well as in Kaohsiung and Pingtung in the south, the air index will flash yellow.
The EPA's six-color scale takes into account ozone, PM2.5 and PM10 particulates, carbon monoxide, sulfur dioxide and nitric oxide concentrations in the air.
Green represents good air quality with an index reading of 0-50; yellow indicates moderate with a reading of 50-100; orange means unhealthy air quality for sensitive groups with a reading of 101-150; red indicates unhealthy quality with a range of 151-200; purple signifies very unhealthy levels at 201-300; and maroon represents hazardous levels at a reading of 301-500.
