Monitoring of the pollution? sources, regular control as well as analyzing of surface water status in small streams is a basic prerequisite for good condition and water quality in the rivers into which they flow. The functioning of the water system includes processes that affect the surface water cycle itself, the reduction of selected characteristics, the removal of toxic substances, the protection of the ecosystem...

Phosphorus is the most important biogenous element that is fundamentally necessary for biological reproduction in all its forms. The occurrence of phosphorus, in the Earth?s crust like carbon, is an example of geochemical relations. Approximately 170 known phosphor minerals in nature. The basic supplies of phosphorus in the earth crust concentrates in apatite that bonds about 95% of the total quantity of phosphorus in the lithosphere. Phosphates - of world production (80%) comes from sedimentary deposits. We have ...
