How polluted is the Arctic atmosphere ???

Last week, the Awi Institute scientists (Alfred Wegener - Ocean and Ocean Research) voiced alarm because the air at the top of the mountains in Ny-Alesund was contaminated at the highest level from So far (the logo has reached orange-orange !!!).

Normally, the air at the peaks is very clean, but due to the special weather from early May, the so-called Aerosol from Eastern Europe brings with it flying objects. gas. Experts have measured 50 micrograms of Aerosol per cubic meter of air at mountain peaks, and this level of pollution is nearly the same as in a crowded city. The Norwegian Institute for Environmental Pollution also warned of measuring dense ozone gas close to the ground: 160 micrograms per cubic meter of air, and this level is also the highest since 1989, when China Center of measurement of air pollution levels was established.

Although experts have also measured dense aerosols in the Arctic in the past years in the spring, the phenomenon of this "blind space" in the Arctic this year has been particularly intense. ever so tall, 2.5 times the level measured in the spring of 2000.

Aerosol are tiny objects in the air, can be liquid or solid and are the core of cloud formation. These particles also have the ability to disperse and even dissolve sunlight, thus greatly affecting climate, weather and the environment.

Andreas Herber of Awi Institute (in Bremerhaven, Germany) expressed concern because: " As a result, the weather will get warmer. This hot trend will continue for a long time, it cannot be concluded because we still have We must continue to measure it again and again. Currently, we are studying Aerosol's origin and chemical composition . "
