Epub 2012 Jul 12. Researchers are presently studying Zn and Cd metabolism in species such as Thlaspi in order to develop a Phyto-Remediation crop which can be used to “depollute” contaminated soils, allowing the shoot Zn to be recycled as an ore. Cadmium contamination of soils and rice plants caused by zinc mining. While excess zinc certainly does harm the plant, it is a much rarer occurrence, and the plant can deal with this situation better. 1. pp. Martell.

Zinc (Zn) is an essential micronutrient for plant life. Sanders, J.R. and T.M. Sanders, J.R., S.P. Craddock.
