4.11 Gas Pollution

Understand the biological consequences of pollution of air by sulphur dioxide and carbon monoxide.

SO2 -> created by the burning of fossil fuels & crude oil
sulphur dioxide combines with water in the atmosphere to form
sulphuric acid.

-> Plants which come in contact with this acid will be burned.
-> Minerals from the soil are leeched by the acid.
-> When acid reaches the lake, it lowers the Ph and forms Aluminium
-> Aluminium ions in the water cause fish to suffocate
----------------

CO2 -> created by incomplete combustion

-> carbon monoxide coats haemoglobin on red blood cells
-> this prevents it from carrying oxygen
-> no oxygen = death
