SMOG IN CHINA

SMOG IN CINA

It happens all the autumns and winters, when increased demand for heating, the Chinese cities are filled with fine particles. But this time in China the levels have reached levels of national emergency, because a large part of the territory of the most populous country in the world is shrouded by a blanket of harmful particulates with a concentration 50 times higher than the limits set by OMS

The particulates are the pollutants most at risk in urban areas and are composed of solid and liquid particles released into the atmosphere. In Changchun, capital of Jilin Province, the concentration reached 860 micrograms per cubic meter in Shenyang, capital of Liaoning Province, even the 1,157 micrograms.

But the new record – with values 56 times higher than the legal limits – was recorded in the northeast of the country, on 8 November, the level of particles came up to 1400 micrograms per cubic meter.

In addition to the capital Beijing and the nearby city of Tianjin, the provinces in greatest suffering are those of Liaoning, Hebei, Henan and Heilongjiang. Due to poor visibility numerous air flights were canceled and even the highways were closed.
