What two units are used to measure the concentration of pollutants in the air?

The emissions of carbon are usually expressed as mass per time (e.g. Mt/yr). Carbon dioxide is usually measured in mass per time (Mt/yr) or volume per time (Mm3/yr). These mass or volume values may be related to Units of power (Mt/GJ) or (MtCO2/MtFuel
The actual measurement of CO2 (which can be converted to C emissions) is done either by sampling the gas flow and analyzing the CO2 in the gas or by adsorption measurements which allows the gas concentration to be calculated by the amount of light it absorbs or transmits. In this case the emissions are measured in parts per mullion volume (ppmv) and transferred into mass or volume emissions from other data like total gas flow.

What is the molarity a measure of?
Molarity (M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to measure the concentration of a solution. Molarity can be used to calculate the volume of solvent or the amount of solute.

What are the units used to measure acids and bases?
The concentration of an acid or base in solution is measured in moles per litre. The strength of an acid or base in solution is measured on the pH scale. This is the negative log of the hydrogen ion concentration. It's a pure number, there are no units.
