“…When plants accumulate metals, the roots and rhizomes generally show higher concentrations than the aboveground parts (Sinicrope et al 1992). This behaviour could be seen in other studies like Reboreda et al (2008) and Duarte et al (2010).…”

Abstract.Heavy metal concentrations present in the above-and beowground tissues of Scirpus maritimus L., Spartina maritima (Curtis) Fernald and Zostera noltii Hornem were analysed seasonally in the Mondego Estuary, Portugal. The sediments of the estuary were confirmed to contain only low concentrations of heavy metals. The belowground tissues of all three species showed higher heavy metal concentrations than the aboveground tissues. Although the sediments only contained low levels of contamination, because the area occupied by S. maritimus and Z. noltii was large, significant quantities of heavy metals were accumulated and exported to the surrounding water bodies. In contrast with observations of highly contaminated estuaries, it was found that in spite of the low level of contaminants in the sediments of the Mondego Estuary, aquatic vegetation functioned as a source of metals for nearby systems.

“…Some plants uptake copper in the roots, shoots and rhizomes (Kadlec and Knight 1996). The reduction of copper concentrations in wetlands has been studied at a variety of sites (Hendrey et al 1979;DeLaune et al 1981;Giblin 1985;Best 1987;Feijtel et al 1989;Schiffer 1989;CH2M Hill 1991& 1992Sinicrope et al 1992), as documented in Knight (1996) andITRC (2003).…”

“…Some plants uptake lead, primarily in the roots (Kadlec and Knight 1996). Lead concentration reduction has been investigated at a variety of wetlands (DeLaune et al 1981;Giblin 1985;Feijtel et al 1989;Schiffer 1989;CH2M Hill 1991& 1992Sinicrope et al 1992;Edwards 1993;Noller et al 1994), as documented in Knight (1996) andITRC (2003). At the SRS A-01 wetlands, recent studies showed lead was very strongly bound to the sediments, with only 5% being easily remobilized and bioavailable (Knox et al 2004).…”

“…The effect of wetlands on zinc has been studied at a variety of sites (Hendrey et al 1979;DeLaune et al 1981;Giblin 1985;Best 1987;Feijtel et al 1989;Schiffer 1989;CH2M Hill 1991& 1992Sinicrope et al 1992;Edwards 1993;Noller et al 1994), as documented in Knight (1996) andITRC (2003). In surface water, zinc is present primarily as divalent Zn(II), which forms sulfides, hydrates, carbonates and organics.…”

“…Direct discharge or wet and dry depositions of contaminants increase the concentrations of trace elements of aquatic systems, thus resulting in their accumulation in sediments (Dunbabin and Bowmer, 1992;Sinicrope et al, 1992). Obodai et al (2011) assessed the level of heavy metal pollution in water, sediments, and two species of fish in Benya and Nakwa lagoons, Ghana and it was concluded that the contamination was the highest in the sediments.…”
