Ammonia (NH₃) Monitoring
Ammonia (NH3) is a compound of nitrogen and hydrogen and is a colourless gas with a pungent smell. Over 80% of ammonia produced worldwide is used in agriculture as fertiliser. It is also used as a refrigerant gas, for purifying water and manufacturing explosives, pesticides and dyes.
Exposure to low levels of ammonia can cause irritation to the nose and throat. Exposure to high levels can cause severe burns to the skin, eyes, throat and lungs.
There have been several incidents of ammonia leaks which have resulted in serious injury and death.
