Abstract:The modalities of cadmium biosorption were studied in four freshwater mollusk species from south Caspian Sea region. Cadmium absorption was measured under hard and soft water conditions as well as under original Tajan River water conditions. Special attention was paid to inter-specific variations of cadmium absorption. Under laboratory conditions the estimated bioaccumulation efficiency was 1350-20,000 for the whole soft body, calculated on a dry mass basis. Concentrations were highest in Dreissena polymorpha, followed by those in Corbicula fluminea, Physa fontinalis and Anodonta cygnea.
