Tropical Storm Doksuri stirs up dust clouds

Taipei, June 28 (CNA) The air quality in southeastern Taiwan dropped sharply Thursday as Tropical Storm Doksuri's outer rim created dust clouds in the area, the Environmental Protection Administration (EPA) said.

At noon Thursday, the concentration of particulates in the air in that area was 1,000 micrograms per cubic meter -- about 20 times higher than usual, EPA data showed.

That level of air pollution is considered a health threat, particularly to people with allergies and respiratory diseases, the EPA said.

The volume dropped slightly in the early afternoon, but the EPA warned that the air quality might remain poor throughout the day.

The dust was from the sand and mud washed down by torrential rains in southern Taiwan a week ago, according to Chu Yu-chi, an EPA official.

The silt on the riverbanks in the area was picked up by the outer rim of Doksuri as it approached the Bashi Channel between the Philippines and Taiwan, he said.
