Common Atmospheric Pollutants from Fossil Fuels

Burning fossil fuels is a major cause of air pollution. Burning fossil fuels produces lots of carbon dioxide, as well as smaller quantities of other pollutants.

Incomplete combustion

Incomplete combustion

  • Incomplete combustion happens when fuels are burned in insufficient oxygen.
  • Incomplete combustion produces two problematic by-products:
    • Carbon monoxide - a toxic gas.
    • Particulates - small solid particles containing carbon and unburnt fuel.
Sulfur impurities

Sulfur impurities

  • Sulfur is an impurity that is present in all fossil fuels.
    • Sulfur oxidises when burned. This produces the toxic gas sulfur dioxide.
Internal combustion engines in cars

Internal combustion engines in cars

  • When fossil fuels are burned in a confined space, the high temperatures can cause nitrogen and oxygen to react.
    • This leads to the formation of toxic nitrogen oxides.
