Other Contaminants

Gaseous hydrogen sulphide (H2S) and carbonyl sulphide (COS) and solid phosphorous pentoxide (P2O5) are all examples of highly-toxic pollutants. These are summarized in this category.

Hydrogen Sulphide (H2S)

Hydrogen sulphide is formed during anaerobic digestion processes and the hydrodesulphurisation of petroleum. H2S is a colourless, toxic gas with an intense stench of rotten eggs. It is extremely flammable and forms explosive mixtures with air.

Ammonia (NH3)

Ammonia is produced, inter alia, in the decay of animal excrement. It is a colourless, toxic gas with a characteristic pungent smell. It has a low flammability and is very soluble in water. The aqueous solution reacts alkaline.
