Maximum allowable concentrations of essential metals, copper and zinc in the soil, in legislations of different countries [PDF]
Zastita materijala, 2015 It is not so easy to predict the toxicity of metals such as copper (Cu) and zinc (Zn) in the soil, due to the high number of factors which can affect their toxic effects. However, it can be said, that these effects constantly grows with increasing metals contents in soils, which is a common consequence of growing anthropogenic contamination.
