PM 2.5 air quality reaches hazardous level in parts of Taiwan

As China’s air quality worsens, northeast seasonal wind carries the hazardous breeze into Taiwan. The air quality in Taiwan has been horrendous for days and it is expected to stay foul for the next two days, according to the Environmental Protection Administration (EPA).
The EPA said air quality in the western part of the country was in the dangerous unhealthy range, with PM 2.5 level reaching the hazardous level of 10 in southwestern Taiwan. The PM 2.5 index is defined as air pollution that contains fine particles smaller than 2.5 millimeters in diameter and is linked to several chronic health problems. In western areas of central and northern Taiwan, the PM 2.5 pollution levels were 9 and 7 respectively.
