How Does Lightning Impact Air Pollution? EPA
2018年9月25日 When nitrogen oxides are created in the atmosphere during a storm, the resulting atmospheric chemistry causes one of the primary air pollutants, ground-level ozone (O 3), to change. Lightning-generated nitrogen oxides have a relatively small but potentially significant impact on ground-level ozone.

Oxygen? Nitrogen? Clearing the Air Tire Inflation Facts
Tires are typically inflated with air that's a combination of roughly 78% nitrogen (N 2 ), 21% oxygen (O 2) and 1% miscellaneous gases. And since all gazes expand when heated and contract when cooled, tire inflation pressures rise and fall with changes in temperature by about one psi (pound per square inch) for every 10° Fahrenheit change in
