Little is known about selenium contents in alcoholic beverages, especially in wine, because no reliable determination method was available so far. A procedure for the detection of selenium in the pg- and low ng-range was developed, which uses the hyd

The ultra trace element bismuth is regulary found in wine on an average of about 0.1 ppb. Very low bismuth contents were also determined in soil and different biomaterials. In spite of those very low quantities even speciation experiments show result
