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

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.

Cadmium adsorption to soil particles is greater in neutral or alkaline soils than in acidic ones and this leads to increased cadmium levels in the soil solution. As a consequence, plant uptake of cadmium decreases as soil pH increases (WHO ...
