As Paul Rozin, often called the «father of the psychology of disgust», has pointed out, we live in a world where the air we breathe comes from the lungs of other people, and contains molecules of animal and human faeces.
With many sources of pollution in some parts of the world, however, air pollution also can contain a mix of hazardous gaseous molecules, such as carbon monoxide, formaldehyde, sulfur dioxide and other volatile organic compounds.

Humans detect smells by inhaling air that contains odor molecules, which then bind to receptors inside the nose, relaying messages to the brain.
The results quantify the nature of gas molecules containing carbon, hydrogen, and sulfur in the earliest atmosphere, but they shed no light on the much later rise of free oxygen in the air.

An parcel means that the medium is small enough to be isothermal and in local thermodynamic equilibrium (which then ensures that the population of thermodynamic molecular energy levels will be set by molecular collisions at the local atmospheric temperature), but the parcel is also large enough to contain a large enough sample of molecules to represent a statistically significant mass of air for thermodynamics to apply.

A «parcel» of air, or «differential» volume of air in any macroscopic discussion is a volume large enough to contain enough molecules that thermodynamic averages pertain to the behavior of the parcel as if the air inside were a continuous fluid, so that when conducting this sort of discussion we can ignore the movement of individual molecules across the surface of (which are in detailed balance anyway, at equilibrium).
Ozone is one of the criteria air pollutants and is a form of oxygen, the molecule contains three oxygen atoms and has the same chemical structure whether it is found high in the atmosphere or at ground - level.
