Why is household ammonia a base




















Ammonia is also produced naturally from decomposition of organic matter, including plants, animals and animal wastes. 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. Most people are exposed to ammonia from inhalation of the gas or vapors. Since ammonia exists naturally and is also present in cleaning products, exposure may occur from these sources.

The widespread use of ammonia on farms and in industrial and commercial locations also means that exposure can occur from an accidental release or from a deliberate terrorist attack. Anhydrous ammonia gas is lighter than air and will rise, so that generally it dissipates and does not settle in low-lying areas. However, in the presence of moisture such as high relative humidity , the liquefied anhydrous ammonia gas forms vapors that are heavier than air.

These vapors may spread along the ground or into low-lying areas with poor airflow where people may become exposed. Ammonia interacts immediately upon contact with available moisture in the skin, eyes, oral cavity, respiratory tract, and particularly mucous surfaces to form the very caustic ammonium hydroxide.

Ammonium hydroxide causes the necrosis of tissues through disruption of cell membrane lipids saponification leading to cellular destruction. As cell proteins break down, water is extracted, resulting in an inflammatory response that causes further damage. Inhalation: Ammonia is irritating and corrosive. Exposure to high concentrations of ammonia in air causes immediate burning of the nose, throat and respiratory tract.

This can cause bronchiolar and alveolar edema, and airway destruction resulting in respiratory distress or failure. Inhalation of lower concentrations can cause coughing, and nose and throat irritation.

Ammonia's odor provides adequate early warning of its presence, but ammonia also causes olfactory fatigue or adaptation, reducing awareness of one's prolonged exposure at low concentrations. Children exposed to the same concentrations of ammonia vapor as adults may receive a larger dose because they have greater lung surface area-to-body weight ratios and increased minute volumes-to-weight ratios.

In addition, they may be exposed to higher concentrations than adults in the same location because of their shorter height and the higher concentrations of ammonia vapor initially found near the ground. Skin or eye contact: Exposure to low concentrations of ammonia in air or solution may produce rapid skin or eye irritation.

Higher concentrations of ammonia may cause severe injury and burns. Contact with concentrated ammonia solutions such as industrial cleaners may cause corrosive injury including skin burns, permanent eye damage or blindness. When used as a refrigerant gas and in air-conditioning equipment, ammonia can absorb substantial amounts of heat from its surroundings.

Ammonia can be used to purify water supplies and as a building block in the manufacture of many products including plastics, explosives, fabrics, pesticides and dyes. Ammonia also is used in the waste and wastewater treatment, cold storage, rubber, pulp and paper and food and beverage industries as a stabilizer, neutralizer and a source of nitrogen.

It also is used in the manufacture of pharmaceuticals. When using cleaning products containing ammonia, follow all instructions on the product label, make sure the area is well ventilated open windows and doors and wear proper clothing and eye protection. Ammonia exposure can irritate skin, eyes and lungs.

Do not mix ammonia with chlorine bleach , as this produces toxic gases called chloramines. Exposure to chloramine gases can cause coughing, shortness of breath, chest pain, nausea, irritation to the throat, nose and eyes or pneumonia and fluid in the lungs.

Swallowing a cleaning product that contains ammonia can burn the mouth, throat, and stomach and cause severe abdominal pain. If a cleaning product containing ammonia is accidentally ingested, read the product label for safety instructions, or call the National Poison Control Center at , and be sure to have the label from the cleaning product in hand.

Medical tests can detect ammonia in blood or urine. But because ammonia occurs naturally in the environment, people are regularly exposed to low levels of ammonia in air, soil and water, so these test results are not considered effective biomarkers of exposure. About 90 percent of ammonia produced is used in fertilizer, to help sustain food production for billions of people around the world. Ammonia has other important uses; for example in household cleaning products and in manufacturing other products.

Ammonia , also known as NH 3 , is a colorless gas with a distinct odor composed of nitrogen and hydrogen atoms. It is produced naturally in the human body and in nature—in water, soil and air, even in tiny bacteria molecules. In human health, ammonia and the ammonium ion are vital components of metabolic processes.
