FACTORS WHICH IMPACT THE RELEASING AND BINDING OF HEAVY METALS IN SOIL SOLUTION
Soil is system, where heavy metals, such as lead, cadmium, copper, etc., can be present in higher concentration then it is usual. Heavy metals are usually present in soil, bounded to clay, but if some conditions, such as pH, acidity, have been changed, then they are released to the soil solution. This work is going to present factors, such as pH, acidity, organic matter content, etc., which have impact on releasing of heavy metals to the soil, and forward to plants. The content of heavy metals in soil solution, such as lead, copper, etc. depend on above mentioned factors, and for different soil conditions, such as organic matter and pH, as the most important factor for binding and releasing of heavy metals from and to soil will be presented.
