What is ammonia used for today?
Ammonia is also used as a refrigerant gas, for purification of water supplies, and in the manufacture of plastics, explosives, textiles, pesticides, dyes and other chemicals. It is found in many household and industrial-strength cleaning solutions.
Some ammonia is converted into nitric acid which itself is used in the manufacture of fertilisers and explosives. Ammonia is also a useful ingredient in some cleaning fluids. Ammonia is a vital route by which nitrogen in the air can be made available to plants to enable them to build protein molecules.
- Ammonia is the preferred nitrogen-containing nutrient for plant growth. Ammonia can be converted to nitrite (NO2 ) and nitrate (NO3) by bacteria, and then used by plants. Nitrate and ammonia are the most common forms of nitrogen in aquatic systems. Nitrate predominates in unpolluted waters.
- It is a COMPRESSED GAS and a confined space explosion and toxicity hazard. Ammonia gas is a CORROSIVE GAS and may be fatal if inhaled. Ammonia gas may cause lung injury, and the liquefied gas can cause frostbite and corrosive injury to eyes and skin. Ammonia gas is a severe respiratory tract irritant.
- Ammonia is also used as a refrigerant gas, for purification of water supplies, and in the manufacture of plastics, explosives, textiles, pesticides, dyes and other chemicals. It is found in many household and industrial-strength cleaning solutions.
Exposure to high concentrations of ammonia in air causes immediate burning of the eyes, nose, throat and respiratory tract and can result in blindness, lung damage or death. Skin or eye contact with concentrated ammonia can also cause irritation and burns.
- Ammonia is a regular metabolite in the central nervous system (CNS). However, when it enters the brain from blood in excessive quantities it becomes toxic to CNS cells. Acute hyperammonemia is often associated with increased cerebral blood flow that by a complex mechanism contributes to hyperammonemic brain edema.
- Ammonia toxicity. Ammonia is highly toxic. Normally blood ammonium concentration is < 50 µmol /L, and an increase to only 100 µmol /L can lead to disturbance of consciousness. A blood ammonium concentration of 200 µmol /L is associated with coma and convulsions.
- When urine begins to smell like ammonia, it usually means one of two things. First, it could be that you are a bit dehydrated and therefore your urine is more concentrated. All urine has ammonia which is a normal product of the metabolism of protein. Another possibility is that your urine is infected with a bacteria.
