Normal amounts of ammonia in the environment do not cause health effects in humans. Exposure to high levels of ammonia may hurt your skin, eyes, throat, and lungs and cause coughing and burns. Lung damage and death may occur after exposure to very high levels of ammonia.
High levels of ammonia can irritate the throat and lungs as well as the mouth, skin, and eyes. In very high levels, ammonia can damage the lungs and may be fatal. This article explains the...
Oral exposure of humans to high concentrations of ammonia and ammonium hydroxide has been shown to result in buccal, esophageal, and upper tracheal burns and edema (Christesen 1995; Klein et al. 1985; Rosenbaum et al. 1998), but no reports of the effects of ammonia on the stomach or upper gastrointestinal tract in humans have been found.
Ammonia is a toxic waste product made by the body during digestion. Without proper treatment, high ammonia levels can lead to confusion, disorientation, and even death.
Ammonia has not been classified for carcinogenic effects by EPA, the Department of Health and Human Services (DHHS), or the International Agency for Research on Cancer (IARC). Ammonia can also have beneficial effects, such as when it is used as a smelling salt.
Ammonia is highly toxic. Blood ammonia levels are usually less than 50 micromoles per liter (micromol /L), but this can vary depending on age. An increase to only 100 micromol /L can lead to changes in consciousness.
Ammonia is a corrosive substance and the main toxic effects are restricted to the sites of direct contact with ammonia (i.e., skin, eyes, respiratory tract, mouth, and digestive tract). For example, if you spilled a bottle of concentrated ammonia on the floor, you would smell a strong ammonia odor; you might cough, and your eyes might water ...
Ingestion of ammonia-containing cleaners occurs predominantly in children and is accidental. However, 9.2% of household exposure is intentional and occurs mostly in adults. Go to: Anhydrous ammonia, in liquid or gaseous form, reacts readily with water in the human tissue to form ammonium ions.
Exposure to high levels of ammonia can cause irritation and serious burns on the skin and in the mouth, throat, lungs, and eyes. At very high levels, ammonia can even cause death. Ammonia has been found in at least 137 of the 1,647 current or former National Priority Sites list identified by the Environmental Protection Agency (EPA).
At lower concentrations, around 0.05 mg/L, un-ionised ammonia is harmful to fish species and can result in poor growth and feed conversion rates, ... In humans, inhaling ammonia in high concentrations can be fatal. Exposure to ammonia can cause headaches, edema, impaired memory, seizures and coma as it is neurotoxic in nature.
