Pregnant women and people with respiratory symptoms are recommended to work from home in case of serious or prolonged fine dust pollution, the environment ministry said Tuesday. The government has been enforcing all-out response measures to reduce fine dust concentration levels in March when ultrafine dust levels usually reach their peak during the year. This year, the temperatures will be higher than in previous years, and the air is likely to be stalled due to the influence of high atmospheric pressure, increasing the likelihood of frequent high levels of ultrafine dust levels, according to the Ministry of Environment. The government will actively encourage the vulnerable class or those sensitive to air quality to work from home, work part-time or adjust the time going to work in case the fine dust warning remains at the "attention" level for over two days or a "caution" level advisory or worse is issued in the four-notch warning system. It also includes inspecting the indoor air quality of schools ahe ad of the new semester and shutting down more generators from public coal-fired power plants from the current 15 to 28. Meanwhile, the environment ministry suggested its Chinese counterpart last month create a minister-level hotline to share each country's responses when a high concentration of fine dust erupts but has not received a reply yet, officials said.
