Lead is naturally found in soil in relatively low concentrations (10-50 mg/kg) in which it is taken up by plants via the roots and accumulates within root cells as lead is used in low levels by plants. Excessive lead concentrations found within plants have been shown to reduce the functionality of morphological, biochemical and physiological functions as well as promoting deleterious effects. For more detailed information on the effects of lead on plant health, see here.
