Lead uptake, toxicity, and detoxification in plants

Lead is also trapped by the negative charges that exist on roots' cell walls.Excessive lead accumulation in plant tissue impairs various morphological, physiological, and biochemical functions in plants, either directly or indirectly, and induces a range of deleterious effects.
