文摘

Fine fraction from samples had high levels of potentially toxic elements (PTEs). In vitro tests with ALF yielded higher bioaccessibility than Gamble's solution. Bioaccessibility in ALF after 2 weeks was high for all PTEs (in % and in mg·kg− 1). PTE bioaccessibility typically increased rapidly, then tended to stabilize over time. PTE solubilization pattern was highly element- and sample-specific.
