Taipei, April 20 (CNA) Air quality was moderate to good all around Taiwan Thursday, with only nine monitoring stations indicating that local air quality was unhealthy for sensitive groups, according to the Environmental Protection Administration's Taiwan Air Quality Monitoring Network.

As of 9 a.m. Thursday, the air quality in Kinmen, Taoyuan's Zhongli District, Taichung's Shalu District, Changhua County's Xianxi and Dacheng townships and downtown Changhua, as well as Yunlin County's Yunbei, Mailiao and Taixi townships, flashed orange, indicating unhealthy air for sensitive groups such as small children, the elderly and people with chronic disease, according to the network (http://taqm.epa.gov.tw/taqm/en/).

For the rest of the country, the air quality was either moderate (yellow) or good (green).

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.
