Incomplete Combustion
- When there is not enough oxygen so some of the fuel DOESN'T BURN.
- Particulates made up of soot (carbon) and unburned hydrocarbons are release. Carbon Monoxide can be produced as well as carbon dioxide.
- Air Pollution
  - Sulfur dioxide (SO2)
    - Released during the combustion of fossil fuels that contain SULFUR IMPURITIES - Sulfur in fuel becomes oxidised
    - When these gases mix with WATER in CLOUDS they form DILUTE SULFURIC ACID and DILUTE NITRIC ACID which then falls as ACID RAIN.
  - Nitrogen Oxide
    - Created from a reaction between the NITROGEN and OXYGEN in the AIR caused by the HEAT of burning.
    - When these gases mix with WATER in CLOUDS they form DILUTE SULFURIC ACID and DILUTE NITRIC ACID which then falls as ACID RAIN.
  - Carbon Monoxide
    - No COLOUR or SMELL so it is very hard to detect.
    - Can stop your blood from CARRYING OXYGEN around your body. Does this by binding to the haemoglobin in your blood that normally carries oxygen. Less oxygen is able to be transported round your body.
  - Problems of Particulates
    - If inhaled, it can get stuck in the lungs and cause damage which can lead to respiratory. problems.
    - GLOBAL DIMMING - Particulates and the clouds they help to produce REFLECT sunlight back into space. Less light reaches the Earth causing Global Dimming.
