Taipei--Air quality was moderate in most Taiwan areas Friday, while the air was found unhealthy for sensitive groups in a handful of places in the south and the outlying county of Kinmen, according to the Environmental Protection Administration's Taiwan Air Quality Monitoring Network.
As of 9 a.m., the air quality flashed "orange" at monitoring stations in Miaoli County's Sanyi township, Kinmen County and the Kaohsiung townships of Qiaotou, Nanzi, Zuoying and Qianzhen, according to the network (http://taqm.epa.gov.tw/taqm/en/).
It means the air was unhealthy for sensitive groups, such as young children, the elderly and people with a chronic disease.
In the rest of the country, air quality was marked "yellow (moderate)" or "green (good)," the data indicates.
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.
