Abstract
The concentration of lead, copper, cadmium and zinc as determined by anodic stripping voltammetry and atomic absorption spectrophotometry in a series of rapeseed oils, meals, and seeds is reported. The metal content of rapeseed seeds is not influenced by growing area; however, the variety appears to affect the metal levels. In general, meals contain twice the heavy metal burden of the seeds. The partitioning of metals between meals and oils heavily favors the meals except for lead where the distribution is approximately two to one.
