Heavy metal is a general collective term for metals and metalloids, and its proportion is > 4 ± 1 g cm − 3.Although this is a broadly defined term, it is generally accepted that heavy metals mainly refer to heavy elements such as arsenic, lead, cadmium . These metals have hardly any biological role to play in the human body but on the contrary their toxic effect causes malfunctioning of the body . However, soil ecosystems are contaminated with heavy metals by human-induced activities (Naidu et al., 1996, Younas & Shahzad, 1998).
