Abstract

Heavy metals that are commonly contaminating soil throughout the world include lead, chromium, arsenic, zinc, cadmium, copper, mercury and nickel. The main sources of these metals are dust produced by energy, transport, metallurgy, production of construction materials; sanitary sewage, chemical wastewater, industrial mining wastewater and urban mining mixed sewage; mining and industrial solid waste contamination; Fertilizers, pesticides and mulch are important agricultural inputs for agricultural production. Among effective ways of removing heavy metals from soil, using chemical extractants are the most cost effective and less damaging, including organic acids and chelating agents.
