In terms of overall range and extents of impacts, however, it is my opinion that burning of fossil fuels (coal, gasoline, etc..) is the single largest source of air pollutants. These fuels cause smog, acid rain, soot and particulates increases, greenhouse gas emissions, and dispersal of some heavy metal contaminants.

What type of air pollution is most harmful?

Ultrafine Particles (UFPs)

UFPs are the most dangerous particulate matter because their tiny size makes them extremely inhalable.

What are the two main types of air pollution?

The two types of air pollutants are primary pollutants, which enter the atmosphere directly, and secondary pollutants, which form from a chemical reaction.
