Our world is enveloped by a layer of atmosphere around 15 kilometers thick layer of the atmosphere consists of nitrogen, oxygen, water vapor and dust. And the microorganisms in the amount of these gases. Gas, the most important of its existence. Life on Earth is oxygen and the layer of the atmosphere with enough oxygen. To live with a thickness of only 5-6 kilometers. This usually consists of various gases is relatively stable nitrogen 78.09%, 20.94% oxygen, carbon dioxide and noble gases. 0.97% for a fixed amount of gas that we hold as fresh air, but whenever a component of climate change to the amount of dust, gas, odor, smoke, vapor, vapor, soot, and the radioactivity in the atmosphere since. too many of us call such conditions as "bad air" or "air pollution".

Ons wêreld is omring deur 'n laag atmosfeer rondom 15 kilometer dik laag van die atmosfeer bestaan ​​uit stikstof, suurstof, waterdamp en stof. En die mikro-organismes in die bedrag van hierdie gasse. Gas, die belangrikste van sy bestaan. Die lewe op aarde is suurstof en die laag van die atmosfeer met genoeg suurstof. Om te lewe met 'n dikte van slegs 5-6 kilometer. Dit bestaan ​​gewoonlik uit verskillende gasse is relatief stabiel stikstof 78,09%, 20,94% suurstof, koolstofdioksied en edelgasse. 0.97% vir 'n vaste hoeveelheid gas wat ons hou as vars lug, maar wanneer 'n komponent van klimaatsverandering op die bedrag van die stof, gas, reuk, rook, stoom, stoom, roet, en die radioaktiwiteit in die atmosfeer sedert. te veel van ons noem die voorwaardes wat "slegte lug" of "lugbesoedeling".
