Air quality fair around Taiwan on Wednesday

Taipei--The air quality was generally good or fair around Taiwan on Wednesday, with particulate levels relatively low in Taipei in the morning, according to the Environmental Protection Administration's Taiwan Air Quality Monitoring Network.

As of 10 a.m., the air quality at all monitoring stations around the country flashed either "green" (good air quality) or "yellow" (fair air quality).

The only exception was the offshore county of Kinmen, which lies just kilometers off China's southeastern coast.

The air quality there flashed "orange," indicating air quality unhealthy for sensitive groups such as young children, the elderly and people with a chronic disease, according to the network (http://taqm.epa.gov.tw/taqm/en/).

In downtown Taipei, PM2.5 particulate levels ranged from 9 to 17 micrograms per cubic meter while PM10 particulates ranged from 27 to 35 micrograms per cubic meter in most parts of the city.

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" or fair air quality 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.
