Cadmium in Plants - USGS

Cadmium is readily absorbed by soil-rooted plants from solu­ tions of cadmium compounds applied to the soil. Autoradiographic studies by Gordee, Porter, and Langston (1960) indicated that exposure of peppermint (Mentha piperita L.) plants to radio­ active cadmium in soil

Cadmium in Soils and Plants SpringerLink

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. The major source of Cd entry to the human body is ...

Cadmium in plants and soil

The amount of cadmium in soils is generally low but once it has been added to the soil, it can take between 100 and 1000 years for the levels to drop by 50%. When cadmium is present in soil, it is more available to plants if the soil is sandy, acidic or low in organic matter.
