- Sulphur dioxide:
- Is added to the atmosphere when the fossil fuels are combusted and also with the combustion of petrol in vehicles
- In the atmosphere, Sulphur dioxide combines with water vapour and forms Sulphuric acid which is also known as acid rain
- Effects on plants and animals:
- They are often burned by the sulphuric acid
- Magnesium and Calcium ions are leached out of the soil which means that the plants can't obtain them from the soil
- Lakes have reduced pH which causes release of Aluminium ions and this effects fish as the Aluminium causes the thickening of the mucus that lines the gills and reduces the fish's ability to take in oxygen. This kills the fish as it suffocates
- Carbon Monoxide:
- Produced when fossil fuels such as coal/gas are burned with insufficient oxygen
- Combines with Haemoglobin in red blood cells and forms Carbaminohaemoglobin which blocks the Haemoglobin from carrying oxygen which reduces oxygen circulation in the body
