The impact of a sandstorm sweeping in from China on local air quality has subsided, although air quality in the south is still not ideal, the Environmental Protection Administration said.
The wind speed in the south has weakened, making conditions less than ideal for the dispersal of airborne suspended particles, the agency said in a press release on Monday.
The latest data on air quality showed that the concentration of suspended particles had dropped to below 100 micrograms per cubic meter in the north, and to around 150 micrograms per cubic meter in the south.
The agency said the sandstorm, which hit northern China on Thursday, mainly affected South Korea and Japan, while Taiwan was affected to a far lesser extent.
The air quality in northern Taiwan, as well as Yunlin, Chiayi, Tainan, Kaohsiung and Pingtung cities and counties, was poor over the past weekend, while the effect on eastern Taiwan was milder.
Suspended particles on Kinmen and Matsu, however, came close to 300 micrograms per cubic meter, the agency said.
