Taipei--The air quality was poor in northern Taiwan Sunday, prompting the Environmental Protection Administration (EPA) to issue an "orange-color" advisory, suggesting the air quality there was unhealthy for sensitive groups, including young children, the elderly and people with chronic disease.
As of 10 a.m., the air quality in Taipei's Songshan District and New Taipei's Wanli, Xizhi, Banqiao, Linkou, Xinzhuang, Yonghe and Tucheng districts, as well as Keelung and Taoyuan cities flashed an orange light, according to data from the EPA's Taiwan Air Quality Monitoring Network (http://taqm.epa.gov.tw/taqm/en/).
The air quality was yellow, meaning moderate quality, in Miaoli and Hsinchu counties in northern Taiwan, as well as Yilan County in the east, central Taiwan and southern parts of the island, the data shows.
For the rest of Taiwan, the air quality flashed green, indicating good 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 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.
