Heavy smog blanketed Korea this week blown in by northwesterly winds from China. The concentration of ultrafine particles is often at its worst between December and March, with most of the smog comes from Beijing and surrounding Hebei Province.
The smog crosses the West Sea and reaches the Korean peninsula anywhere between six hours and a day later. Meteorologists say the smog is diluted as it crosses the West Sea, but 40 to 50 percent still reaches Korea.
On Thursday, the concentration of ultrafine particles in Dongducheon, Gyeonggi Province north of Seoul, reached 255㎍/㎥, five times the normal level in the region. It stood at 138 ㎍/㎥ in Incheon and 112㎍/㎥ in the capital.
The concentration of ultrafine particles in Dongducheon was 2.5 times greater than the safe level set by the Environment Ministry of 100㎍/㎥ per day.
