Air quality mostly fair Friday

Taipei--Air quality was moderate to good around Taiwan Friday except one area in northern Taiwan's New Taipei City, according to the Environmental Protection Administration's Taiwan Air Quality Monitoring Network.

As of 11 a.m., eastern Taiwan's Hualien and Taitung Counties enjoyed good air quality (green) while in Hsinchu, Miaoli, Changhua, Yunlin, Tainan and the island counties of Kinmen, Matsu and Penghu, the air quality was moderate (yellow), according to the network. (

For the rest of the country, air quality was a mixed bag of moderate and good except Wanli District in the north of New Taipei City, where the air quality flashed orange, indicating the air was unhealthy for sensitive groups such as young children, the elderly and people with a chronic disease.

For Saturday, eastern Taiwan likely will continue to enjoy good quality air while the air quality in the central and southern parts of western Taiwan is expected to be unhealthy for sensitive groups.

The northern part of western Taiwan, including Taoyuan, Hsinchu and Miaoli, 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.
