Taipei--Air quality was good or fair in Taiwan on Wednesday, even in more industrial areas in central and southern Taiwan that are more vulnerable to pollution, according to the Environmental Protection Administration's Taiwan Air Quality Monitoring Network.
As of 11 a.m., the air quality flashed either "green (good)" or "yellow (fair)" at monitoring stations around the country, according to the network (http://taqm.epa.gov.tw/taqm/en/).
The yellow signal flashed in a few districts and townships in northern and central Taiwan, Lunbei and Douliu Townships of Yunlin County and Puzi Township in Chiayi County in the south, and the islands of Matsu and Kinmen.
The rest of the country saw good air quality, the monitoring data showed. 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.
The network assesses air quality based on a six-level scale, with green indicating good air quality, yellow showing fair air quality, orange signaling unhealthy air quality for sensitive groups, red indicating unhealthy air quality for everybody, purple signaling very unhealthy air quality, and maroon representing hazardous air quality.
