Acting President Choi Sang-mok on Monday directed relevant government agencies to implement emergency environmental measures as ultrafine dust warnings were issued for parts of the country.
Choi instructed the environment ministry and provincial governments, among others, to implement dust reduction measures, mandating high-emission facilities and construction sites to modify or reduce their operating hours to protect workers. He also mandated that these measures be communicated to the public.
The environment ministry said the control measures, the first in about a year, will go into effect from 6 a.m. until 9 p.m. Tuesday.
Earlier in the day, ultrafine dust warnings, for particles smaller than 2.5 micrometers in diameter, were issued for parts of the greater Seoul area and South Chungcheong Province. (Yonhap)
