Taipei, Oct. 9 (CNA) People in central and southern Taiwan should take precautions as the air quality there has deteriorated to an unhealthy level for sensitive groups due to a lack of wind to disperse atmospheric pollutants, the Environmental Protection Administration (EPA) said Monday.

The poor air quality is expected to last through Wednesday as pollutants such as ozone and fine particulate matter smaller than 2.5 micrometers (PM2.5) accumulate in the still air in those regions, which are currently seeing sunny and stable weather, according to the EPA.

The air quality index is flashing orange, indicting an unhealthy quality for sensitive groups such as young children, the elderly and people with chronic diseases, the EPA said.

The most heavily affected areas on Monday were Sanyi Township in Miaoli County, Xianxi Township in Changhua County, Linyuan District in Kaohsiung City and the whole of Pingtung County, the EPA said.

The EPA advised sensitive groups in areas with poor air quality to avoid strenuous activities and wear face masks outdoors.

The air quality in the southern half of the country might begin to improve Thursday with the arrival of northeastern winds accompanied by rain across the country, the EPA said.

On the EPA's six-color scale, green represents good air quality with an index reading of 0-50; yellow indicates moderate 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 signals very unhealthy levels at 201-300; and maroon represents hazardous levels at a reading of 301-500.
