Heavy metals in the soil alludes to some critical heavy metals of biological toxicity, including mercury (Hg), cadmium (Cd), lead (Pb), chromium (Cr), and arsenic (As), etc. With the improvement of the global economy, both sort and substance of heavy metals in the soil caused by human exercises have gradually expanded lately, which have brought about genuine condition deterioration. In present investigation we looked at and analyzed soil contamination of heavy metals in different urban areas/nations, and evaluated foundation, effect and remediation methods of soil heavy metal contamination around the world.Heavy metals are notable environmental contaminations because of their toxicity, industriousness in the environment, and bioaccumulative nature. Their regular sources include enduring of metal-bearing rocks and volcanic ejections, while anthropogenic sources include mining and different industrial and horticultural exercises. Digging and industrial preparing for extraction of mineral assets and their consequent applications for industrial, rural, and monetary improvement has prompted an expansion in the assembly of these components in the environment and unsettling influence of their biogeochemical cycles.
