Taipei, May 19 (CNA) Air quality was unhealthy for sensitive groups in parts of central and southern Taiwan on Friday, according to the Environmental Protection Administration's Taiwan Air Quality Monitoring Network.

As of 11 a.m., air quality flashed orange at monitoring stations in Shalu District of Taichung, and some areas in the central and southern counties of Changhua, Yunlin, Chiayi and Pingtung, as well as Kaohsiung, the largest port city in the south, according to the network (http://taqm.epa.gov.tw/taqm/en/).

It means the air quality was unhealthy for sensitive groups, such as young children, the elderly and people with a chronic disease. In Yunlin's Lunbei Township, air quality flashed red, indicating unhealthy for the general public.

Air quality in the rest of the country was either green (good) or yellow (moderate), the monitoring data showed.

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 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.
