,Conclusion — Prospects for the EU,nt tissue were accumulated during the past decade. The current widespread interest in the Cd content of plants arises from investigations revealing the harmful health effects of high dietary intake of Cd. Although acute Cd toxicity caused by food consumption is rare, chronic exposure to high Cd leve

This Chapter is concerned with three elements, arsenic, selenium and antimony, which are commonly identified with the toxic or potentially toxic metals, but in view of their chemical and physical properties they are more suitably termed metalloids

Whether the problem is deficiency or toxicity there is a need for knowledge to describe how Zn exists in the soil, enters and is transported within the plant, and the role it plays in the biochemistry and physiology of the plant.

The effort has been spread widely, from the macroecological viewpoint at one extreme, down to the molecular viewpoint and, encouragingly, some highly successful attempts have been made to deal with the intimate details of the actions of metal ions, both ‘essential’ and ‘
