Ammonia fertilizer pollutant

As previously mentioned, fertilizer manufacturing may create problems within all environmental media, that is, air pollution, water pollution, and solid wastes disposal difficulties. In particular, the liquid waste effluents generated from phosphate and mixed and blend fertilizer production streams originate from a variety of sources and may be summarized [17,27] as follows (a) ammonia-bearing wastes from ammonia production (b) ammonium salts such as...

First, as dung and urine of animals, which contains both organic matter and large concentrations of nutrients. However, care must be taken to avoid the contamination of surface and ground waters with pathogenic bacteria. This method of organic fertilization also causes local air pollution with ammonia and distasteful smells.

When the electrode is exposed to ammonia (an atmospheric pollutant from fertilizer and other sources), the pH jumps to near 9 by the buffering action of NU4 plus excess NH3 in the liquid. We will study buffers in the next chapter. NH3 is very soluble in water and does not readily diffuse back into the air when the electrode is held in the air. 

Ammonia (NH,) is emitted primarily from animal shelters, cleaning detergents, and fertilizer production. Ammonia in the aqueous phase establishes equilibrium with NH4, which results in increased pH. NH, affects the atmospheric corrosion chemistry by partly neutralizing acidifying pollutants, forming particulate ammonium sulfate [(NH4),S04] and acid ammonium sulfates such as NH4HSO4 and (NH4)4H(S04),.
