Carbon monoxide
Like carbon particulates, this is also formed by incomplete combustion, where there isn't enough oxygen to become carbon dioxide
Carbon monoxide binds with the red blood cells irreversibly, preventing them from carrying oxygen
If exposed over a period of time, carbon monoxide can easily be fatal, as you would suffocate due to lack of oxygen
It is removed from exhausts using a catalytic converter. This reacts with the carbon monoxide and and forms nitrogen and carbon dioxide
Sulfur dioxide
Sulfur is an impurity in most fossil fuels, so it is released when it is burned, and it reacts with oxygen
Sulfur dioxide is the main cause of acid rain, which can be very destructive and problematic
In industry, sulfur dioxide is a problem. To remove it from the chimney flutes, it is sprayed with an alkali solution, like calcium oxide. The reaction could be :SO2 + H2O → H2SO3
And then : H2SO3 + CaO → CaSO3 + H2O
Nitrogen oxide
They are made when nitrogen and oxygen from the air react in high temperatures, like engines
Nitrogen oxide causes problems like acid rain, photochemical smog and respiratory problems
To reduce the emissions of nitrogen oxide, exhausts can be fitted with a catalytic converter. This reacts with carbon monoxide to form less harmful carbon dioxide and harmless nitrogen
