Cyanuric acid is implicated in connection to the 2007 pet food recalls, the contamination and wide recall of many brands of cat and dog foods beginning in March 2007. Research has found evidence that cyanuric acid, a constituent of urine, together with melamine forms poorly soluble crystals which can cause kidney failure (see Analysis section ...
It also occurs with heat pumps due to acid in the insulation, and it reacts with cyanuric acid (which is added as a chlorine stabilizer) to produce copper cyanurate. This phenomenon is called 'Purple Cyanurate', as it discolours the surfaces and the water of the pool to a purple shade. [1]
Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir. [1]
A practical definition of water pollution is: "Water pollution is the addition of substances or energy forms that directly or indirectly alter the nature of the water body in such a manner that negatively affects its legitimate uses." [1]: 6 Water is typically referred to as polluted when it is impaired by anthropogenic contaminants.
Cyanuric acid has also been used as NPN. For example, Archer Daniels Midland manufactures an NPN supplement for cattle, which contains biuret, triuret, cyanuric acid and urea. [66] FDA permits a certain amount of cyanuric acid to be present in some additives used in animal feed and also drinking water. [67]

Water pollution (or aquatic pollution) is the contamination of water bodies, with a negative impact on their uses. [153]: 6 It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come ...
Adverse human health effects have been associated with a compound. There is an established relationship between the positive and negative effect(s) of the compound. Emerging contaminants are those which have not previously been detected through water quality analysis, or have been found in small concentrations with uncertainty as to their effects.
