Scholarcy highlights

  • Metal contaminants in garden and allotment soils could possibly affect human health through a variety of pathways
  • This study focused on the potential pathway of consumption of vegetables grown on contaminated soil
  • Five cultivars each of six common vegetables were grown in a control and in a soil spiked with Cd, Cu, Pb and Zn
  • Significant differences in metal content were evident between cultivars of a number of vegetables for several of the contaminants
  • Carrot and pea cultivars exhibited significant differences in accumulated concentrations of Cd and Cu with carrot cultivars exhibiting significant differences in Zn. Distinctive differences were identified when comparing one vegetable to another, legumes tending to be low accumulators, root vegetables tending to be moderate accumulators and leafy vegetables being high accumulators
