Toxicity of heavy metals (Zn, Cu, Cd, Pb) to vascular plants

Of the metals reviewed, Zn is the least toxic. Generally plant growth is affected at 1000 μg Zn L−1 or more in a nutrient solution, though 100 to 200 µg L−1 may give cytological disorders. At concentrations of 100 to 200 μg L−1, Cu and Cd disturb metabolic processes and growth, whereas the phytotoxicity of Pb generally is lower.
