Taipei--The air quality was fair to good in most parts of Taiwan on Wednesday, but it was poor in southern Taiwan and the outlying island of Matsu, according to the Environmental Protection Administration's Taiwan Air Quality Monitoring Network.
As of 11 a.m., the air quality in the eastern counties of Yilan, Hualien and Taitung and most parts of northern Taiwan flashed a green light, meaning the air quality in those regions was good, network data showed (http://taqm.epa.gov.tw/taqm/en/).
Most parts of central Taiwan flashed yellow lights, meaning the air quality was fair, according to the network.
The air quality in most parts of Pingtung County in southern Taiwan, and the outlying islands of Kinmen and Penghu also flashed yellow lights, the data showed.
The outlying island of Matsu and other parts of southern Taiwan, including Tainan and most parts of Kaohsiung, flashed orange lights, meaning the air quality was unhealthy for sensitive groups, according to the network.
For Thursday, the air quality is expected to flash orange in Kaohsiung, Pingtung, Yunlin, Chiayi and Tainan; yellow in northern and central Taiwan; and green in Yilan, Hualien and Taitung.
The agency's color scale takes into account ozone, PM2.5 and PM10 particulates, carbon monoxide, sulfur dioxide and nitric oxide concentrations in the air.
