Taipei--Air quality was good around Taiwan Tuesday, except in some parts of the island and the offshore Kinmen County, where the air quality is moderate, according to the Environmental Protection Administration's (EPA's) Taiwan Air Quality Monitoring Network.
As of 10 a.m., out of around 75 monitoring stations around Taiwan, 13 flashed yellow, meaning local air quality was moderate, while the rest were green, indicating good air quality, according to the network (http://taqm.epa.gov.tw/taqm/en/).
Those monitoring stations showing yellow were scattered around the island, including the Taipei region in the north, Yunlin County and Kaohsiung City in the south, etc.
For Wednesday, most areas in Taiwan will continue to see moderate air quality while the eastern half of Taiwan and the Penghu Islands to the west are expected to enjoy 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 a pollutant reading of less than 50; yellow indicates "moderate" at 50-100; orange means "unhealthy for sensitive groups" with a reading of 101-150; red indicates "unhealthy" with a range of 151-200; purple signifies "very unhealthy" with a level of 201-300; maroon represents "hazardous" with a reading of 301-500.
