In addition to the volatile organic compounds found in water, ammonia is an inorganic compound that may occur in drinking water supplies and is frequently present in waste-waters. Ammonia nitrogen exists in both the dissolved gas form (NH3) and in true solution (NHp. These two species are present in a dynamic equilibrium according to the equation ... 

Ammonia can be used to excrete waste nitrogen in certain aquatic species because they live in water. The toxic effects of ammonia are therefore immediately diminished after it is excreted into a large body of water. This strategy is not practical for mammals which are land animals who store liquid waste for intormittent excretion. Ammonia is very soluble in body fluids and would accumulate to toxic levels if not... 

Any process that follows conventional primary and biological treatment may be considered to be advanced treatment. Nitrogen exists in diverse forms in wastewater, including domestic and industrial wastes. As bacteria decompose waste, nitrogen in complex organic molecules is released as ammonia, which can exist in water either as ammonium ion (NH ) or as ammonia gas (NH3). The ammonia or ammonium concentration in water can be seriously affected by industrial discharge as well as by agricultural fertilizer runoff [1,21].

Primary urea cycle defects are caused by a deficiency of any of the six urea cycle enzymes (Chap. 15) and result in insufficient disposal of waste nitrogen. As a result, nitrogen accumulates in the form of ammonia and as its precursors, as glutamine and glycine. Primary defects in an enzyme of the urea cycle typically result in higher ammonia levels than secondary impairments of the urea cycle, although exceptions occur. 

The primary function of the urea cycle is to rid the body of waste nitrogen. Deficiency in the activity of any of the six enzymes in the urea cycle may result in the accumulation of ammonia, often to toxic concentrations. Treatment involves restricting protein, preventing catabolism, supplementing amino acids that are normally produced by the urea cycle, and promoting the excretion of nitrogen via alternative pathways. Outcomes are guarded and appear to be better for patients identified by NBS compared to patients identified clinically. Liver transplantation is a treatment option, especially for patients with a severe form of the disorder. 

Ammonia and ammonium ions in industrial water streams, including waste-water streams, can be determined by either of two methods (ASTM Procedure D1426). In the first, the sample is buffered to a pH of 7.4 and distilled into a solution of boric acid where the ammonia nitrogen is deterrnined colorimetricaHy with Nessler reagents or titrated using standard sulfuric acid.
