Contributions of Wetland Plants on Metal Accumulation in Sediment

چکیده

Wetlands, and especially salt marshes, are well-known sinks of metals, which limit toxic amounts metals from entering the food chain. This study investigated metal concentrations (Cr, Cu, Fe, Mn, Ni, Pb, Zn) in a highly urbanised estuary, compared vegetated rhizosediment (Salicornia tegetaria, Spartina maritima, Zostera capensis) with bare sediment, depositional non-depositional site, intertidal zone Swartkops Estuary. The samples were collected at two sites along middle lower reaches estuary analysed using Total X-ray Fluorescence (TXRF) spectrometer. It was found that contained more sediment decreased as follows: S. tegetaria > maritima Z. capensis sediment. Although accumulation similar for (Site B) site A), displayed higher B). However, regardless site-specific tendencies, than These results indicate should be focus monitoring estuaries around world.

Susceptibility of riparian wetland plants to perfluorooctanoic acid (PFOA) accumulation.

As plants have been shown to accumulate organic compounds from contaminated sediments, there is a potential for long-lasting ecological impact as a result of contaminant accumulation in riparian areas of wetlands, particularly the accumulation of non-biodegradable contaminants such as perfluorooctanoic acid (PFOA). In this study, commonly found riparian wetland plants including reeds, i.e., Xan...

Metal Tolerance, Accumulation, and Detoxification in Plants with Emphasis on Arsenic in Terrestrial Plants

A number of review articles have appeared in the literature recently on metal accumulation by plants. However, reports on the tolerance, accumulation and detoxification of arsenic in plants, especially in terrestrial plants, are limited. In light of the strong needs for study of arsenic biogeochemistry and development of arsenic decontamination techniques, in this paper we. review arsenic uptak...

Heavy Metal Accumulation in Wild Plants: Implications for Phytoremediation

This work addresses the issue of Zn, Cu, Pb, Cd, Ni and Cr accumulation in wildgrown plants in the context of their possible use for the sanitation of sludge and waste substrates. The highest contents of heavy metals were noted in Lactuca serriola, Chenopodium album, Artemisia vulgaris and Atriplex nitens. Assuming maximum crop production which is to be obtained from sludge and waste substrates...
