Suwon City will implement a fine dust alert and warning system starting this month.
Suwon, Hwaseong, Pyeongtaek, and Osan cities are designated as one region, and the Gyeonggi Province Institute of Health and Environment will issue announcements twice daily. The fine dust alerts will report current conditions at 9 a.m. and forecast the next day's fine dust situation at 6 p.m.
Alerts will be issued in six levels so that the general public can easily understand the severity of fine dust hazards.
A fine dust caution will be issued when the fine dust concentration in 1 cubic meter reaches 200㎍ or more for two hours or longer, and an alert will be issued when it reaches 300㎍ or more.
A city official explained, "Fine dust not only causes respiratory diseases, but in severe cases, it can lead to decreased lung function."
The city particularly urged the elderly and children to refrain from going outdoors when fine dust alerts and warnings are issued, and requested that in unavoidable cases, they should wear masks.
Meanwhile, in the case of Suwon City, from 2003 to last year, fine dust in the atmosphere exceeded the average standard criteria approximately 8 to 9 times each year on average.
