OUTDOOR AIR PROPERTIES
Behind the Fresh Air
The composition of outdoor air has been well established as consisting of 18 essential elements and compounds. Additional elements in the air, including those identified as pollutants, are found in minuscule quantities of parts per million, or even per billion. Each of these elements exists in both a stable molecular form and unstable ionic form, adding a third classification of elements to the list.
Staying with us so far? For instance: Hydrogen is found as H+ and as H2. Oxygen is found as O-, O2, and O3. The same is true for every element of the composition list.
The composition of outdoor air varies greatly worldwide, dependent on the amount of energy in the air. The reactivity of the air and its ability to break down pollutants determines the rate at which the air can freshen itself. The amount of energy found in the air depends on sunlight (solar and thermal radiation), wind, and the rate the energy is depleted (amount of pollutants) for any given area. Outdoor air’s energy is responsible for the fresh air we breathe today despite eons of earth’s many environmental calamities.
The energies of outdoor air are consistently replenished, keeping the air consistently fresh, which our bodies love!
