Transfer of cadmium from naturally Cd-enriched soils to plants in the Gurnigel (Jura Mountains, Switzerland)
Cadmium transfer, under natural conditions, from naturally Cd-enriched soils to plants is still in need of more detailed investigations. A description of the project (analyses and parameters to be performed) carried out at the Le Gurnigel site (NE, Switzerland), intended to complete previous geochemical data is presented. Three types of soils and three ranges of Cd concentrations were combined to obtain nine sampling points. Six species of local plants were chosen for study of their hebaviour in regard to accumulation of Cd in their roots and aerial parts. The first results of Cd accumulation in the sampled plants in two zones at different Cd- concentrations in soils are presented. All six species present different behaviour even between plants from the same family. The role of physicochemical factors in soils on these accumulations will he determined with further analyses.
