Taipei--The air quality in southern Taiwan and the offshore county of Kinmen was mostly poor on Wednesday, according to the Environmental Protection Administration's Taiwan Air Quality Monitoring Network.
As of 11 a.m. Wednesday, the air quality in Kinmen and many parts of Kaohsiung City and Pingtung County flashed red, indicating the air quality in those areas was unhealthy for the general public.
The air quality throughout much of the rest of western Taiwan, including the capital Taipei, flashed either yellow (moderate) or orange (unhealthy for sensitive groups), according to data released by the network.
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 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; and maroon represents "hazardous" with a reading of 301-500.
The air quality on Thursday is forecast to remain unhealthy in Kaohsiung and Pingtung; unhealthy for sensitive groups in central Taiwan and Yunlin, Chiayi and Nantou; fair in northern Taiwan, Hsinchu, Miaoli and Yilan; and good in Hualien and Taitung.
