Abstract

Unified Bioaccessibility Method (UBM) assay was used to characterize the bioaccessibility of Pb in 11 soils from Dalian and Zhuzhou. The results revealed that the bioaccessiblity of Pb in stomach covered between 21.1% and 77.9% with the average being 54.5% while those in intestine ranged between 0.2% and 4.2% with the average being 0.7%. Significant positive correlation between the total Pb, manganese and phosphate content and the bioaccessible Pb concentration in stomach was observed while the bioaccessible Pb in intestine correlated well with the concentration of total Pb in soil and bioaccessible Pb content in stomach. Significant positive correlation between the bioaccessible Pb concentration in stomach and intestine and the weak acid extractable, reducible and oxidative Pb was observed, and most bioaccessible Pb was contributed by the weak acid extractable, reducible and oxidative Pb. In addition, parts of residual Pb characterized by sequential extraction method (BCR) could be dissolved in acidic solution in gastric phase.
