| Abstract | Propertiesf verticalistributionf soil near water bodies are vary considerably from thosef land and may greatly affect the transportationf heavy metalsn wetlands. Verticalistributionsf heavy metals (Cr, Cd, Cu, Pb, and Zn)n the soilf aquatic-terrestrial ecotone (ATE)f Lake Taihu, China, andn wetland plant tissues were studied. Generally, concentrationsf heavy metalsecreased withncreasingepthn the top 40-cm cores and thenncreased slightly withncreasingepth. Thisnvestigationndicated that concentrationsf Cd, Cr, Pb, and Zn exceeded the geochemical background valuesn the Taihu Lake area. Concentrationsf Cd at allepth soil columns exceeded the Environment Quality Standard for Soilsf China. Correlation analysis showed that concentrationsf Zn, Cr, Cd, and Pb correlated significantly withne another, suggesting that they had the samerigin. The concentrationf Cu was negatively correlated with root biomass, which may explain the lower concentrationf coppern the soil cores. Theominant plantsf the wetland were Phragmites australis and Ludwigia prostrata, and heavy metal accumulated primarilyn the root tissue. The generalrder was root > rhizome > stem > leaf, whereasn L. prostrata, leaf was the main tissue for Cr accumulation. Both P. australis and L. prostrata had the highest concentration factor (CF) to Cu, and CF was 20.3 and 15.8, respectively. Aquatic-terrestrial ecotone plants are more effectiven controlling Cu pollution thanther heavy metals. This will be very significant for ATE reestablishment near Cu-polluted sites. |
