Taipei--Air quality was poor in many places in Taiwan on Friday, especially in the northern and central parts of western Taiwan, according to the Environmental Protection Administration's (EPA's) Taiwan Air Quality Monitoring Network.
As of 11 a.m., the air quality in many parts of Taipei, New Taipei, Taoyuan, Hsinchu, Miaoli, Taichung, Changhua, Nantou, Yunlin and Chiayi flashed orange, indicating that the air quality is unhealthy for sensitive groups including young children, the elderly and people with a chronic disease.
The air quality in the rest of western Taiwan flashed yellow, meaning the air quality was "moderate," according to the network.
The air quality in Hualien, Taitung and the Penghu Islands, meanwhile, flashed green, indicating good air quality.
For Saturday, the air quality is expected to flash orange in northern Taiwan, Hsinchu, Miaoli, central Taiwan, Yunlin, Chiayi, and Tainan; yellow in Kaohsiung, Pingtung and Yiland; and green in Hualien and Taitung.
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.
