Sorption of heavy metals from polluted water and their migration in the system soil‐tree

Abstract

Abstract Large amounts of various contaminants are transported via natural processes from technogenic pollution sources to air, water, soil and natural ecosystems. Heavy metals (HM) are very hazardous substances having long‐lasting impact on ecosystems. They have complex negative impact on human health, animals, flora and fauna at watercourses and microflora of wastewater. Often concentration of HM exceeds maximal available concentration in wastewater. HM enter forests in their wet and dry forms from local or outer atmosphere sources; they are also brought from seas alongside with biogens and sea salt or washed from putrid or putrescent plants that concentrate in the soil or they are brought by wind or water together with mineral particles. Monitoring of forests determined that contaminants, i e HM inhibit energetic status of a tree and cause increase of tree sensitivity to diseases. In this paper the most commonly met HM, such as Ni, Mn, Zn, Pb, Cu and Co, are analysed. Pollution with HM can be reduced, ...
