Sulphur Dioxide, also called SO2, is a colourless gas that is created through the burning and smelting of fossil fuels and sulphur-containing mineral ore.

Created through the burning and smelting of fossil fuels and sulphur containing

When dissolved in water SO2 becomes sulphurous acid.

SO2 reacts with body moisture sulphurous and sulfuric acids are formed which can
cause chemical burns.
