Taipei, Sept. 20 (CNA) The air quality in some northern and central parts of western Taiwan Thursday was generally rated "unhealthy," because of a lack of wind and stable weather that did not disperse atmospheric pollutants, according to the Environmental Protection Administration (EPA).
As of noon, the EPA's Air Quality Index (AQI) flashed an orange warning, indicating unhealthy air for sensitive groups, at 10 monitoring stations in parts of western Taiwan, including seven in northern Taiwan, the EPA's Air Quality Monitoring Network showed.
The AQI in the leeward northern and central parts of western Taiwan is expected to flash a red waning, meaning unhealthy air for the general public, or an orange alert later Thursday as the conditions were not right for dispersing atmospheric pollutants there, according to the EPA.
In the rest of western Taiwan and all of eastern Taiwan, the air quality will be rated as either good or fair, the EPA forecast.
The EPA's AQI takes into account ozone, PM2.5 and PM10 particulates, carbon monoxide, sulfur dioxide and nitric oxide concentrations in the air.
The EPA said that the condition for dispersing atmospheric pollutants will be also unfavorable in northern areas of western Taiwan Friday and the AQI there is expected to flash an orange warning in the evening.
It advises people in areas with poor air quality to avoid outdoor activities if they experience eye irritation, coughing or a sore throat.
People with cardiovascular or respiratory diseases, children, and the elderly in affected areas should avoid staying outdoors or use a mask to prevent exposure to air pollution, the EPA said.
