Description:
Ammonia and nitrite are highly toxic to fishes, wig ammonia occurring in urface waters more commonly than nitrite. itrate is a related compound but is not ignificantly toxic to fishes. he acute toxicity of ammonia to aquatic organisms s affected by water pH, dissolved oxygen, temperature, concentration fluctuations, egree of salinity, presence of other chemicals, and prior acclimation. he acute oxicity of nitrite is known to be affected by water pH and the presence of chloride nd calcium. ore research is needed on the effects of these and other variables on he acute toxicity of both ammonia and nitrite, as well as the chronic effects of oth of these toxins.
