TLDR
A critical evaluation of the literature data on the ammonia–water equilibrium system has been carried out and results of calculations of values of pKa at different temperatures and of percent of NH3 in aqueous ammonia solutions of zero salinity as a function of pH and temperature are presented.Abstract:
The toxicity of ammonia to fishes has been attributed to the un-ionized ammonia chemical species present in aqueous solution Because the percent of total ammonia present as un-ionized ammonia (NH3) is so dependent upon pH and temperature, an exact understanding of the aqueous ammonia equilibrium is important for toxicity studies A critical evaluation of the literature data on the ammonia–water equilibrium system has been carried out Results of calculations of values of pKa at different temperatures and of percent of NH3 in aqueous ammonia solutions of zero salinity as a function of pH and temperature are presentedread more

TL;DR: In this article, a comprehensive study was undertaken to evaluate the tidal and seasonal variations in nutrient concentrations (nitrate, phosphate, sulphate and ammonia) of the Rupsha-Passur River System during October, 2010 (Post monsoon), February, 2011 (Dry winter) and August 2011 (Monsoon).

Effects of water matrix on virus inactivation using common virucidal techniques for condensate urine disinfection
TL;DR: Based on the findings in this study, UV disinfection could be recommended for disinfecting the reclaimed water from the evaporation of source-separated urine for reclaimed water.

TL;DR: Although the ammonia concentration increased until 1,864 ± 23 mg/l, no inhibition phenomenon was determined in the stability variables, methane yield, or kinetics parameters studied, and the studied mixture showed high anaerobic biodegradability.

The Interactions of Diet and Colonic Microflora in Regulating Colonic Mucosal Growth
TL;DR: There are unique interactions between specific types of diet and microflora that lead to a growth-promoting effect and this effect could not be explained by alterations in the concentration of SCFAs, ammonia, or bile acids in colonic contents.

Effect of ammonia on respiratory functions of blood of Tilapia zilli
TL;DR: An examination of different changes of blood respiratory properties when Tilapia zilli is exposed to ammonia in three sublethal concentrations for 2 weeks revealed that oxygen and carbon dioxide partial pressures were changed differently and irregularly both in the caudal artery and in the heart.

The Percent Un-Ionized Ammonia in Aqueous Ammonia Solutions at Different pH Levels and Temperatures
TL;DR: In this article, it was shown that the un-ionized ammonia molecule and not the ammonium ion is the form of the toxicant harmful to fish, and the amount of unionised ammonia in the water was quantified.
