- Title
Accumulation of arsenic and zinc in the rhizosphere of wetland plants.

- Abstract
The article presents a study of the concentrations of arsenic (As) and zinc (Zn) in ironplaque, rhizosphere and bulk soil of wetland plants such as Spartina anglica and Halimione portulacoides. The study uses Pye Unicam SP9 flame atomic absorption spectrophotometer (FAAS) to analyze the accumulation of As, iron (Fe) and Zn in soils. Results suggest that the effects of plants on metal retention by wetlands can be through oxidation of rhizosphere that increases iron oxyhydroxides in soil.
