[Solved]: Ammonia NH3 chemically reacts with oxygen gas O2 t This document discusses the effects of the increasing inorganic nitrogen pollution. Ammonia reacts with oxygen to form nitrogen and water. When ammonia concentrations or fluctuations increase within streams, ammonia concentrations within aquatic organisms may rise owing to reduced nitrogen excretion and increased diffusion of ammonia across gill membranes. For example, taxa particularly sensitive to unionized ammonia, such as unionid mussels and fish, may decrease, while more tolerant organisms become more dominant. Reduced fecundity and reproductive success. Comparative Biochemistry and Physiology, Part B 121:99-109. Without catalyst, ammonia is only oxidized to nitrogen gas.
