The status of trace elements in staple foods from the former Federal Republic of Germany

Abstract

In repräsentativen Proben von Brotgetreide und Getreideprodukten aus der Bundesrepublik werden die Gehalte von 11 Spurenelementen für das Jahr 1989 analysiert. Es wird gezeigt, daß die Ergebnisse repräsentativ für die alte Bundesrepublik sind, wenn man sie mit den Ergebnissen aus den vergangenen 15 Jahren vergleicht. Die Probennahmetechnik für die Herstellung von Grundnahrungsmittelproben wird erklärt. Zertifizierte Standard-Referenz-Materialien wurden verwendet, um die Ergebnisse der Analysen abzusichern. In representative samples of bread cereals and cereal products from the former Federal Republik of Germany (FRG) the status of 11 trace elements was analysed in 1989. It is demonstrated that the results are quite representative for the former FRG as compared with results published in the previous 15 years. The sampling technique for staple foods is explained. A number of certified standard reference materials were used to validate the analytical methods employed.
