摘要Trace metals in mangrove tissues (leaf, branch and root) of two species (Rhizophora stylosa and Sonneratia hainanensis) from Dongzhai Harbor and Sanya Bay of Hainan Island were studied. The total average concentrations of Cu, Pb, Zn, Cd, Cr, Hg and As in the two mamgrove species were 2.4 +/- 1.3, 1.1 +/- 0.7, 7.8 +/- 8.0, 0.03 +/- 0.05, 1.4 +/- 1.6, 0.03 +/- 0.01 and 0.2 +/- 0.2 mu g g(-1) dw, respectively. Metals concentrations among different tissues of mangroves showed different pattern. In general, Zn, Cd and Hg were slightly enriched in leaf, Cu, Pb and As was enriched in root, and Cr were enriched in branch. Metals levels in R. stylosa and S. hainanensis from both Dongzhai Harbor and Sanya Bay were compared, which suggested that different mangrove species have their unique mechanism to bioaccumulate metals and TOC in the mangrove sediment could be one of the important factors for regulating metals in mangrove tissues. The biota-sediment accumulation factors (BSAF) of metals in mangrove tissues were calculated. The distribution of metals concentrations in mangrove tissues against metals levels in sediment demonstrated that mangrove leaves could be employed as a bio-indicator for some metals (Cu, Zn, Cd and Hg) with temporal monitoring.
