Abstract. Cadmium can be a potential threat to a wide range of biota because (i) it is non-essential and non-metabolic, (ii) it is toxic to humans at concentrations lower than those toxic to plants, (iii) it is more mobile and bioavailable than other metals, and (iv) its effects on humans are cumulative.
