Ammonia is a toxic waste product produced by bacteria in the intestines during protein digestion. Under normal circumstances, ammonia is processed in the liver, where it is turned into a less toxic chemical called urea and eliminated through the urine.WEBAmmonia is diffused and transported across all plasma membranes. This entails that hyperammonemia leads to an increase in ammonia in all organs and tissues. It is known that the toxic ramifications of ammonia primarily …WEBThe severity of ammonia toxicity on all organs and tissues most likely depends on the degree and acuteness of the onset of hyperammonemia, therefore a better understanding on the consequences of inherited and acquired, as well as acute and chronic hyperammonemia merits to be thoroughly investigated.WEBInhalation of ammonia may cause nasopharyngeal and tracheal burns, bronchiolar and alveolar edema, and airway destruction resulting in respiratory distress or failure. Ammonia's odor threshold is sufficiently low to acutely provide adequate warning of its presence (odor threshold = 5 ppm; OSHA PEL = 50 ppm).WEBAmmonia is an upper respiratory irritant in humans, causing immediate irritation to the nose and throat upon exposure. Acute accidental exposure to ammonia gas can lead to human death as a result of airway obstruction or infections and …WEBAbstract. Abnormal liver function has dramatic effects on brain functions. Hyperammonemia interferes profoundly with brain metabolism, astrocyte volume regulation, and in particular mitochondrial functions. Gene expression in the brain and excitatory and inhibitory neurotransmission circuits are also affected.WEBAIHA [1971] also reported that 5,000 to 10,000 ppm are reported to be fatal [Mulder and Van der Zahm 1967] and exposures for 30 minutes to 2,500 to 6,000 ppm are considered dangerous to life [Smyth 1956].
