[Square-wave polarographic determination of heavy metals in vegetables with special regard to cadmium]

The cadmium contents of 104 foods mostly of vegetable origin (market samples from a highly industrialized area in the GDR) were determined by means of square-wave polarography. The values obtained are in good agreement with literature data about the cadmium contents of foods, and they are not indicative of an increased contamination of the products under investigation compared to other industrialized countries.
