Atmosphere

atmospheric composition
Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%.
Carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere.
Changes
-
pollutants such as carbon monoxide and sulfur dioxide are likely to be given out from busy cities and industrial areas. But since air is continually on the move, the pollutants get spread around too.
Testing and treatment

Treatment
Filtration
In filtration, water passes through a filter, which is made to take away particles from the water.
pH Correction
To adjust pH levels, lime is combined with filtered water.
-
Extraction
fractional distillation.
-
the gases in air have different boiling points. So when liquid air is warmed up, the gases boil at different temperatures, and can be collected one by one.
