“…From these results HCl (1.00 mol L 1) appears more aggressive than EDTA (0.05 mol L 1) and release more As, Cd, Cr, Cu, Ni, Pb and Zn. Nevertheless, Leleyter et al (2012) show that EDTA is suitable tor estimating Pb mobility and sequential extraction for Cu and Zn.…”

“…Following the conclusion of these studies, a hypothesis can be advanced that the enrichments of Cr, Ni, Pb and Zn could be attributed to recent contamination (the recent connections can be weak and therefore easily reversible). According to Baize et al (2009), Varrault (2012 and Leleyter et al (2012) an anthropic enrichment can imply a high element mobility from sediments. Rao et al (2010) show that the accidentally polluted soil (contaminated by mining activity) had the highest recoveries by HCl extraction; Rousseau et al (2009) simulated enclosed harbors areas in order to study the impact of sacrificial anode dissolution.…”

“…Many authors (Audry, 2003;Leleyter and Baraud, 2005;Dubrulle et al, 2007;Meybeck et al, 2007;Leleyter et al, 2012) use the enrichment factor (EF) approach to easily visualize atypical enrichment which may be anthropogenic. The EF formula (Covelli and Fantolan, 1997) uses an internal reference, known as a normalizer, to moderate the deviations produced by heterogeneous sediments (Magesh et al, 2011).…”

“…HCl 1.00 mol L 1 is assumed to extract metals due to its acidic properties combined with the chelatant property of Cl . Hydrochloric acid has been used extensively as a reagent in this type of study and is recommended by many authors (Duinker et al, 1974;Scouller et al, 2006;Doherty et al, 2000); for harbor sediments 1.00 mol L 1 is often suggested (Szefer et al, 1995;Burton et al, 2005;Larner et al, 2008;Leleyter et al, 2012). The phyto-available fraction of the element is often estimated by extractions performed using complexing agents which are assumed to extract elements present in the sample on the exchange sites of both the carbonate and organic fractions.…”

“…The phyto-available fraction of the element is often estimated by extractions performed using complexing agents which are assumed to extract elements present in the sample on the exchange sites of both the carbonate and organic fractions. The most widely used chelating agents for bioavailability assessment are ethylene diamine tetra-acetic acid (EDTA) and diethylene triamine penta-acetic acid (DTPA) (Fangueiro et al, 2002;Di Palma et al, 2005;Leleyter et al, 2012). Unbuffered salt extractants are rarely used for marine samples because they are not adapted to the high ionic strength of these samples (Leleyter et al, 2012).…”

(H. Hamdoun). Ab s t r a c tFor a full assessment of the environmental risk posed by dredged sediments not only the anthropogenic enrichment of contaminants, but also their mobility and biological impact should be considered. This study reports on the enrichment factor (EF), mobility, and Adverse Effect Index (AEI) of metals and metalloids in nine dredged sediments. Significant enrichment of As, Cd, Pb and Zn with respect to background values is detected, and calculated AEI values for these elements suggest that it is possible that a corresponding biological effect may be observed. Correlation coefficients also reveal a link between mobility in HCl and enrichment for Cd, Cr, Ni, Pb and Zn, however As and Cu do not display such a link, possibly suggesting that the source of contamination for these elements is less recent. Mobility and enrichment are two parameters which are often studied separately; however this paper shows that in some cases strong correlations occur.

Content and bioavailability of trace elements and nutrients in grape pomace

et al. 2019

BACKGROUND The possible agricultural use of grape pomace could be limited by the content and mobility of metals. This is influenced by many factors. In this study, the abundance and availability of heavy metals and essential nutrients were evaluated comprehensively in different grape pomace residues from winemaking of five white and red grape varieties, before and after the distillation process. RESULTS The total metal content found in grape pomace skins and seeds confirmed that there was greater metal accumulation in skins than in the corresponding seeds, with the exception of Ca and Mg. The enrichment of all metals (except K) during the distillation stage was confirmed by means of a significant correlation (R = 0.996, P < 0.001) between the metal content obtained in distilled and undistilled samples. Regarding availability, multivariate statistical analysis showed different behavior among elements, but a great similarity for metal mobility in both distilled and undistilled grape pomace samples and in both skins and seeds, except for Mn, Zn and Mg. CONCLUSION The results obtained in this study suggest the potential application of these grape residues as organic fertilizers for agricultural soils, without limitations resulting from heavy metal contamination. © 2019 Society of Chemical Industry
