“…Hydroxylamine hydrochloride appears thus to be more specific for solubilisation of the Mn-oxides associated fraction as suggested in the literature (Gleyzes et al, 2002). The additional steps, targeting Fe (and also Al) oxides, added in this study to the classical Tessier method contribute significant amounts of Cu ranging from 19% up to 37% in some samples.…”

“…Sadiq (1997) suggested that carbonate minerals are expected to adsorb arsenic in alkaline soils and arsenic associated with this fraction was found in alkaline soils with a high CaCO 3 content by Gleyzes et al, 2002. The pH of soils in this study ranges from 2.9 to 6.8 which does 156 Operationally defined associations of arsenic and copper from soil and mine waste in south-west England not favour arsenic associations with the carbonate fractions.…”

“…For comparison, the fractionation results for arsenic, in this scheme, are also included. Gleyzes et al (2002) found that Cu extracted in the organic fraction of the Tessier protocol was overestimated (as confirmed by single extractions specific for the organically bound Cu applied to the same samples). The high recovery of the organically bound Cu found in this study in samples, which had a relatively low organic matter content, suggest that there may be a high proportion of sulfides in these samples and thus Cu extracted in this fraction represents mainly the sulfide-bound rather than the organically bound phase.…”

“…The classical Tessier scheme was also designed for non-polluted or slightly polluted soils. Its application to industrial or mining polluted soils has not been studied widely (Gleyzes et al, 2002). Samples from very polluted areas have much higher contents of trace elements and Fe.…”

“…Samples from very polluted areas have much higher contents of trace elements and Fe. The Tessier scheme applied to these soils did not allow a correct evaluation of the Fe associated fraction and lead to the overestimation of the residual fraction, giving in consequence a far too low risk assessment (Gleyzes et al, 2001(Gleyzes et al, , 2002.…”

Arsenic and copper fractionation was studied in contaminated soil and mine waste materials from a mining site in Devon, UK. Ten soil samples with Cu concentrations ranging from 300 -6144 mgykg and As concentrations ranging from 5512 -39715 mgykg were sequentially extracted using the modified method of Tessier et al. (1979) and Wenzel et al. (2001). The Classical Tessier et al. (1979) scheme was shown to be inadequate for studying either Cu or As fractionation as it severely underestimated the Feoxide associated fraction. The Modified Tessier et al. (1979) scheme, including the two additional steps specifically targeting Fe-oxides, was shown adequate for both Cu and As fractionation; however the Wenzel et al. (2001) protocol allows the prediction of changes in lability of As in various solid phases as a result of soil remediation or alteration in environmental factors. In agreement with other studies, arsenic was found to be held predominantly in the amorphous Fe-oxide fraction (55% -94%), which can be potentially mobilised with a change in redox conditions. A significant proportion of As can also be remobilised from the soils through the process of anion exchange. Copper presented a different fractionation pattern as it was distributed mainly between the organicysulfide and the Fe -Mn oxide fractions. Although the total concentrations of Cu in the soils are much lower than As, Cu appears to be solubilised to a much greater extent as indicated by the higher percentage contribution of Cu in the easily mobilisable fractions.

A greenhouse study was conducted to evaluate and compare arsenic accumulation from four arsenic contaminated soils by two arsenic hyperaccumulators, Pteris vittata and Pteris cretica. After growing in soils for six weeks, the plants were harvested and separated into above-and belowground biomass. Total As, P, Ca, K, glutathione and biomass were measured for the plants, and total As, Mehlich-3 P and As, exchangeable K and Ca, and arsenic fractionation were performed for the soils. Pteris vittata had significantly higher total biomass (14 g/plant) and As accumulation than P. cretica. Arsenic accumulation in both ferns followed the arsenic concentrations in the soil. The P/As molar ratio in the fronds, growing in arsenic contaminated soils, ranged from 80 to 939 in P. vittata and 130 to 421 in P. cretica. Plant arsenic concentrations were significantly positively correlated with Mehlich-3 arsenic in the soils. Soil pH was also significantly correlated with Mehlich-3 arsenic before and after plant uptake. Plant As uptake was significantly correlated with exchangeable potassium in the soil before plant uptake. Glutathione availability was not implicated as a major detoxification mechanism in these ferns. Though both plants were effective in taking up arsenic from various arsenic contaminated soils, P. vittata was overall a better candidate for phytoremediation of arsenic contaminated soils.
