Air quality good around Taiwan

Taipei--The air quality was generally good in northern and eastern Taiwan and fair around the rest of the country on Wednesday, the Environmental Protection Administration's (EPA's) Taiwan Air Quality Monitoring Network data showed.

As of 11 a.m., most monitoring stations in the northern half and eastern part of Taiwan, as well as parts of southern Taiwan and the outlying Matsu Islands, flashed green, indicating good air quality, according to the network (

Monitoring stations showing yellow -- meaning fair air quality -- were scattered around central and southern Taiwan, including some stations in Chiayi, Yunlin, Tainan, Kaohsiung and Pingtung, the data showed.

Monitoring stations in the outlying Kinmen and Penghu islands also flashed yellow, it said.

On Thursday, most areas in Taiwan will continue to see fair air quality while the eastern half of Taiwan is expected to enjoy good air quality.

The air quality in Kaohsiung and Pingtung in southern Taiwan, however, is expected to flash orange, indicating that the air quality is unhealthy for sensitive groups including young children, the elderly and people with chronic diseases.

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 51-100; 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.
