Food chain transfer of Pb is one of the major pathways
for human exposure to Pb contamination in soils. The aims
of this study were, therefore, to investigate the effect of
various soil amendments on Pb accumulation by vegetables
(Brassica campetris L. var. communis, pakchoy and Brassica
oleracea L. var. acephala, known as Chinese kale)
grown in contaminated soil, and its relation to changes in Pb
speciation under various soil amendments.
