[세종=뉴시스] Reporter Byun Hae-jeong = On the 13th, the third day of the Lunar New Year holiday and Saturday, the whole country was covered with hazy ultrafine dust (PM2.5).

The air quality is expected to be bad even on the 14th, the last day of the Lunar New Year holiday, so it is better to avoid going out as much as possible. In particular, emergency reduction measures are implemented in the metropolitan area and Chungcheong area.

According to the National Institute of Environmental Sciences under the Ministry of Environment, as of 5 pm on the 13th, the average daily concentration of ultrafine dust in Seoul was 72㎍/㎥, which is’bad’ (36~75㎍/㎥).

It soared to 114㎍/㎥, which was once’very bad’ (more than 76㎍/㎥).

Out of the 25 districts in Seoul, 8 have an average daily concentration of ultrafine dust that is’very bad’. Yangcheon-gu 100㎍/㎥, Guro-gu 98㎍/㎥, Gangseo-gu 97㎍/㎥, Yeongdeungpo-gu 91㎍/㎥, Geumcheon-gu 86㎍/㎥, Mapo-gu 85㎍/㎥, Dongjak-gu and Seocho-gu 80㎍/㎥.

Besides Seoul, there were many areas with cloudy air.

The average concentration of ultrafine dust per day in Chungnam was 78㎍/㎥, which was’very bad’. The highest value was taken as 172㎍/㎥.

Gyeonggi (75㎍/㎥), Incheon (69㎍/㎥), Sejong (63㎍/㎥), Chungbuk (54㎍/㎥), and Jeonbuk (48㎍/㎥) showed poor levels of average daily ultrafine dust concentration. ㎥), Daejeon (45㎍/㎥), and Gwangju (39㎍/㎥) in 7 cities and provinces. In particular, in Gyeonggi (167㎍/㎥), Chungbuk (132㎍/㎥), Incheon (126㎍/㎥), and Sejong (101㎍/㎥), it temporarily increased to the 100㎍/㎥.

The remaining eight cities and provinces, such as Jeju (27㎍/㎥) and Busan (31㎍/㎥), have an average daily ultrafine dust concentration of’normal’ (16~35㎍/㎥), but the highest value is up to a bad level. Soared.

An official of the Institute of Environmental Sciences explained, “As the season in which the effect of high mobility high pressure approaches is approaching, it is judged that the high concentration situation continues as the warm temperature and the wind strength weaken, and the foreign influence from the western wind increases.”

The high concentration of ultrafine dust will continue on the 14th, the last day of the Lunar New Year holiday.

It is predicted that the southern part of Gyeonggi Province will show’very bad’, while Seoul, Incheon, northern Gyeonggi, Gangwon Yeongseo, Chungcheong area, Gwangju and Jeonbuk will show’bad’ level. Seoul, Incheon, and Chungnam will temporarily rise to’very bad’ levels in the morning.

In particular, emergency reduction measures have been issued in Seoul, Incheon, Gyeonggi, Sejong, Chungbuk, and Chungnam. The average daily concentration of ultrafine dust exceeds 50㎍/㎥ by 4 pm on that day in the region, and it is predicted to exceed 50㎍/㎥ on the 14th, meeting the ultrafine dust crisis warning criteria, which is a condition for implementing emergency reduction measures. .

The ultrafine dust crisis alert ▲An average of 50㎍/㎥ exceeded at 0~16:00 on the day and expected to exceed 50㎍/㎥ tomorrow ▲ At 0~16:00 on the day, warnings and warnings were issued in the relevant municipalities and expected to exceed 50㎍/㎥ tomorrow ▲ Tomorrow 75 It is issued even if only one of the three criteria is met, such as the expected exceeding ㎍/㎥.

Ultrafine dust has a smaller particle size than fine dust, so it is not filtered through the nasal mucosa and penetrates deep into the body, increasing the prevalence and early mortality of asthma and lung diseases.

Children, the elderly, and people with respiratory diseases should wear a health mask that can protect the respiratory tract from harmful particulate matter such as yellow dust and fine dust, rather than a surgical mask or cotton mask called a dental mask.

The Ministry of Environment did not issue emergency reduction measures to minimize public discomfort during the Lunar New Year holiday period, 11-13. Instead, as it has a great impact on the public’s health, it induces voluntary reduction of large-emission workplaces with local governments and strengthened monitoring of road water cleaning and illegal incineration.
