| 中文摘要 | In this study, we compared the spatial distribution of total metals (Cu, Pb, and Zn) and bioaccessible metals, which were quantified by incubating sediments with the digestive fluid of sipunculans Sipunculus nudus, in natural sediments of the Pearl River Estuary (PRE). The spatial distribution of bioaccessible metal was not the same as that of total metals in PRE sediments, which were mainly controlled by fine-grained size, total organic carbon (TOC) and Fe. Geochemical factors were important in interpreting this different spatial variation. The similar spatial variations of bioaccessible Cu and total Cu were related to TOC in PRE sediments. Differently from the total Zn, a higher bioaccessible Zn was detected near the West Channel of PRE because of a lower TOC. However, the distribution of bioaccessible Pb was not significantly related to any sediment geochemistry. This study provides a more accurate view of metal pollution in the PRE natural sediments.
