Plant roots aided by plant produced chelating agents and plant induced pH changes and redox reactions are able to solubilize and take up micronutrients from very low levels in the soil even from nearly insoluble precipitat Plants have also evolved highly specific mechanisms to translocate and store micronutrients These same mechanisms are also involved in the uptake translocation and Lead occurs naturally in soils typically at concentrations that range from 10 to 50 mg/kg milligrams of lead per kilogram of soil equivalent to parts of lead per million parts of soil or ppm Because of the widespread use of leaded paint before the mid s and leaded gasoline before the mid
