I think you should start to narrow your question down to

- emission source (industrial, traffic, fire)

- pollutant (CO, NOx, PM, SO2, O3 ...)

Then, maybe, someone can help you.

Bayan Hussien

Well,

Emission Factors The emission factor is the amount of pollutants emitted from the consumption of a quantity of fuel and is calculated in controlled conditions for different types of vehicles depending on the type of fuel used and the quantity, as well as operating conditions (from the speed and different engine conditions). The unit used to measure the emission factor is kg/ton (mass/mass) for mostly fixed sources and kg / 1000 km (mass/distance) for moving sources (vehicles). There is an emission factor for each fuel burned for each industry and the unit is kilograms of gas or pollutant per ton of burned fuel. For example, the combustion of one ton of oil produces 20.1 kilograms of sulfur dioxide.

An emission factor is a representative value that attempts to relate the quantity of a pollutant released to the atmosphere with an activity associated with the release of that pollutant. Emission factors usually are expressed as the weight of pollutant divided by the unit weight, volume, distance, or duration of the activity that emits the pollutant.
