Taipei--Air quality ranges from moderate to good in most parts of Taiwan Monday but it was unhealthy for the general public in the islands of Kinmen, according to the Environmental Protection Administration's Taiwan Air Quality Monitoring Network.
As of 11 a.m., the monitoring station in Kinmen is the only one around Taiwan that flashed red, according to the network. (http://taqm.epa.gov.tw/taqm/en/).
The air was best in eastern Taiwan, where monitoring stations in Yilan, Hualien and Taitung Counties all flashed green, indicating good air quality.
For the western half of Taiwan and the Matsu and Penghu Islands, the air quality was moderate (yellow), with some pockets in Taipei, New Taipei, Taichung, Changhua and Yunlin showing orange, indicating air quality that was unhealthy for sensitive groups such as young children, the elderly and people with a chronic disease.
For Tuesday, eastern Taiwan will likely continue to enjoy good-quality air while the rest of the country could see air quality that will be unhealthy for sensitive groups, according to 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 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.
