Taipei--Air quality ranged from moderate to good around Taiwan Tuesday except Kinmen Islands and parts of southern Taiwan, according to the Environmental Protection Administration's Taiwan Air Quality Monitoring Network.
As of 11 a.m., the monitoring stations in Kinmen, Yunlin County's Lunbei, Mailiao and Taixi and Kaohsiung City's Nanzi and Qianzhen flashed orange, according to the network. (http://taqm.epa.gov.tw/taqm/en/).
The color orange on the administration's six-color scale means the air is unhealthy for sensitive groups such as young children, the elderly and people with a chronic disease.
For the rest of Taiwan, the air quality was moderate (yellow) to good (green), especially in eastern Taiwan and the southern tip of the island in Pingtung County.
For Wednesday, eastern Taiwan's Hualien and Taitung Counties will likely continue to enjoy good-quality air while the western half of the country could see air quality that will be unhealthy for sensitive groups, according to the network.
The EPA's 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.
