Trace elements and heavy metals in selected medical, spice and dietetic eatable plants

Abstract
Data concerning the content of micronutrients and heavy metals in special plant products (spice plants, medicinal plants, dietetic products) from Austria were collected and compared to other food of plant origin. Special attention is given to cadmium, which is highly mobile in soils and available to plants.
Different aspects concerning the Cd uptake of plants are studied in pot experiments. Mainly the repartition of this element in the plant, the influence of other trace elements and some climatic and soil parameters are considered. Among the test plants are poppy (Papaver somniferum), chamomilla (Chamomilla recutita) and St. John´s wort (Hypericum perforatum). These experiments give information which plant tend to accumulate Cd and which cultivation techniques are suitable to minimize the Cd uptake.
