General characteristics

Phosphor is on eleventh place according to its presence in Earth. The most phosphates occur in apatite, three calcium-phosphates. The big consumption of chemical sons increases phosphate production. Phosphates are using also for production of special glass, Chinese disuses, powder for pastry and detergents. Sodium, potassium and ammonium-phosphates are soluble in water, but from compounds of calcium to monocalcium-phosphates, solubility is limited. 

Origin in water 

Phosphor origin in waters is from different shapes of calcium-phosphates, which occur in metamorphic and sedimentary rocks. All phosphor compounds in underground waters occur in small quantities (tenth or hundredth part of milligrams per litre) and reason for that is small compounds solubility. High phosphor compounds signify on their pollution, because phosphor compounds belong to decay products of complex organic material. Sources can have phosphates during the natural contact with minerals or because of pollution during the application of artificial sons and waste waters (15-30 mg/1 PO43-) and industrial waste.

Medical aspect

Phosphor has important place in metabolism. It is macro element and the most part (about 80%) is disposed in bones and teeth. Phosphor is in content of proteins, nucleic acids, nucleotides, adenosine three phosphates, which is important for energy release necessary for reduction processes. Resorption of phosphor is in intestine.

Positive effect

Phosphor activate calcium adopts in intestine. It besets appearances of osteoporosis, appetite and decrement of mind and physical activity. Organic phosphates positively react on muscle mass, hair and digestion. 

Negative effect

Phosphor odds perturb calcium adoption from intestine and formation of vitamin D3.

Maximal allowable concentrations

According to recommendations of EU (Directive 98/83/EC) phosphates are not any more as parameter of interest.
