Air quality mostly fair Saturday, with some exceptions

Taipei--Air quality was moderate to good around Taiwan Saturday except parts in northern and southern Taiwan and the islands of Kinmen, according to the Environmental Protection Administration's Taiwan Air Quality Monitoring Network.

As of 11 a.m., monitoring stations in Kinmen, Yangmingshan in Taipei City and Qiaotou in Kaohsiung City flashed orange, indicating local air quality was unhealthy for sensitive groups such as young children, the elderly and people with a chronic disease, according to the network.

But for the rest of the country, air quality was moderate to good, especially in Yilan and Taitung Counties in eastern Taiwan and the Matsu Islands to the northwest of Taiwan proper, where people could enjoy good-quality air.

For Sunday, Yilan will likely continue to enjoy good-quality air but the western half of Taiwan could see air quality that would be unhealthy for sensitive groups, with the exception of Hsinchu and Miaoli Counties, where the air quality is expected to be moderate.

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.
