Abstract

The uptake of cadmium (Cd) was analyzed for 6 different perennial plant species growing in a wooded pasture on the northern face of the Mont d'Amin (canton Neuchâtel), where the soils are geogenically enriched in Cd. High Cd concentrations in the soil result in a reduction of Cd accumulation in the shoots and a corresponding increase in the roots. This implies that Cd transfer coefficients from the soil/rhizosphere to the plant are inversely proportional to the total Cd concentrations in soils and do not depend on plant species but instead on soil type. Therefore, this may represent a long-term hazard for livestock and human health since these plants are used either by grazing cattle or for medicinal purposes
