摘要

In order to estimate heavy metals partitioning in soil or sediments, to evaluate their mobility and so their bioavailability , a 7-steps sequential chemical extraction procedure had been developed. But as the efficiency and selectivity of the acido-soluble extraction was now controversed, the objective of this complementary study was to show that this fraction is actually essentially composed of carbonates (as calcite or dolomite), but phosphates (as apatites) are few solubilized during this extraction step.
