Abstract
Heavy metals decompose in the soil and cause pollution that is difficult to remove, due to their inability to turn into other compounds. Recently, the increase in population and increasing demand and industrialization and intensive agricultural practices in line with this cause environmental pollution. Heavy metal pollution can also occur from the parent material. Among the heavy metals in the soil, cadmium (Cd), copper (Cu), lead (Pb), cobalt (Co), arsenic (As), mercury (Hg) and zinc (Zn) have an important place. Heavy metal pollution can cause losses in agricultural areas, as well as adversely affect human health with the consumption of products grown in these areas. Heavy metal pollution in the soil can be controlled by physical, chemical or biological methods and/or processes, by isolation techniques, replacing contaminated soil, electrokinetic techniques, leaching and bioremediation techniques. In this review, heavy metal pollution and removal methods were evaluated.
