"dust"

Korea on Sunday was blanketed by dangerous levels of ultrafine dust expected to persist until at least Monday, which prompted the government to issue emergency reduction measures for the first time this year.

With cool-to-cold weather upon us and changing air pressure as well as more people travelling, the dust problem is returning, Public Health Minister Anutin Charnvirakul said on Thursday after a meeting with the Committee on Occupational Disease Control and Environmental Diseases.

Bangkokians should prepare for PM2.5 dust (particles less than 2.5 micrometres in diameter) during the cooler season from December to February, while real-time air quality information can be checked via websites and a phone application, the governor said on Wednesday.

The Pollution Control Department said the PM2.5 dust situation is presently at the standard level of 5-27 mcg/cu across Thailand.

Chulalongkorn University’s Faculty of Engineering, in collaboration with PTT, has come up with a new three-layer face mask that provides protection from both fine dust particles and Covid-19.
