Air quality mostly good around Taiwan Saturday

Taipei--Air quality up and down Taiwan was mostly good Saturday as a weather front moving in from the north overnight brought cleaner air as well as occasionally heavy showers, according to the Environmental Protection Administration's Taiwan Air Quality Monitoring Network.

As of 10 a.m., air quality monitoring stations in regions normally prone to serious air pollution such as Changhua and Yunlin Counties flashed green, indicating good air quality, according to the network (http://taqm.epa.gov.tw/taqm/en/).

Only the island county of Kinmen and some parts of the Taipei region, central and southern Taiwan had the second best level of air quality -- moderate.

No parts of Taiwan had worse air quality than moderate.

For Sunday, when the weather is expected to turn dry, central and souther Taiwan could see air quality that would be unhealthy for sensitive groups while eastern Taiwan could expect good air quality.

The rest of the country is expected to have moderate air quality.

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.
