Air quality poor in northern, southern areas

Taipei--The air quality was so poor on Sunday in northern and southern Taiwan that it was determined as unhealthy for the general public, not just at-risk groups, according to the Environmental Protection Administration's (EPA's) Taiwan Air Quality Monitoring Network.

As of 10 a.m., the air quality flashed "red," in New Taipei's Linkou district, Taoyuan's Dayuan and Pingzhen, Yunlin County's Mailiao, Lunbei and Taixi, Chiayi County's Xingang and Chiayi City and Tainan's Xinying, as well as the offshore county of Kinmen, according to the network at

Due to the poor air quality, the EPA advised people to avoid outdoor activities.

Meanwhile, the air quality flashed "orange" in offshore Matsu island and central Taiwan, meaning the air was unhealthy for sensitive groups, such as young children, the elderly and people with a chronic disease.

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 for the general public 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.
