Smog from China engulfs Korea, Chinese gov. won't reveal data about its pollutants-Chosun

11/1/13, "Toxic Smog from China Engulfs Korea," english.chosun.com

"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. ...

Winter smog carries more ultrafine particles and is more hazardous than the sandstorms that blow over here in spring. According to the National Institute of Environmental Research, around 20 to 30 percent of sandstorms consist of ultrafine particles, but smog contains 60 to 70 percent....

It is difficult to predict smog levels since it is not clear where it originates and how many pollutants it contains. The Chinese government does not reveal data about the origin of pollutants, but the most polluted parts of China are along the east coast, which is near Korea."
