Antimony (sb) is a potential environmental contaminant of emerging concern that occurs in soils in the sb(V) oxidation state as the antimonate species sb(OH) 6 -. In soils, metal oxyhydroxides play an important role in the immobilization of contaminants and in restricting bioaccessibility. One such mineral is gibbsite, which bears the reactive aluminol surface functional group. Both inner-and outer-sphere surface complexation mechanisms have been inferred from conflicting sb(V) adsorption findings involving aluminol-bearing minerals. The objectives of this research are to characterize sb(V) adsorption by gibbsite and to use the macroscopic findings to develop mechanistic adsorption models. Antimonate adsorption envelopes were developed using two equilibrium techniques: continuous pH titration and batch. The adsorption of sb(V) decreases with increasing pH and increasing ionic strength, suggesting that outer-sphere surface complexation is an important adsorption mechanism. However, sb(V) retention is irreversible at pH <6 but is reversible in pH >7 systems, suggesting that inner-sphere species may be significant in acidic environments. Adsorbed sb(V) also generates a downward shift in the gibbsite isoelectric point, further supporting the formation of inner-sphere sb(V) surface complexes. Both PO 4 and sO 4 decrease adsorbed sb(V) concentrations: PO 4 throughout the pH 3 to 10 range and sO 4 in pH <7 systems. The triple-layer surface complexation model successfully predicts sb(V) adsorption by using both outer-sphere and inner-sphere surface species. The triple-layer model also predicts ligand adsorption in the competitive systems without the need for reoptimization.Abbreviations: BET, Brunauer-Emmett-Teller; ICP-AES, inductively coupled argon plasma-atomic emission spectroscopy; IEP, isoelectric point; SCM, surface complexation model; TLM, triple layer model; XRD, x-ray diffraction.A ntimony is one of the least abundant elements in soils, having a median concentration in uncontaminated soils from around the world of 1 mg kg −1 (range, <0.2-10 mg kg −1 ) (Bowen, 1979;Filella et al., 2002;Helmke, 2000). However, anthropogenic activities can result in elevated soil Sb levels (Crecelius et al., 1975;Filella et al., 2002;Li and Thornton, 1993;Nriagu, 1989;Nriagu and Pacyna, 1988;Scheinost et al., 2006). Soils that are particularly affected by Sb are those at military and civilian shooting ranges. Antimony is a hardening agent in lead bullets, which contain ~5% Sb (Carlin, 2000;Johnson et al., 2005;Kilgour et al., 2008). As bullets and bullet fragments corrode, Pb and Sb are released to the soil environment (Clausen and Korte, 2009;Kilgour et al., 2008). The resulting Sb concentrations can far exceed native soil levels. Antimony concentrations in military and civilian shooting range soils have been reported to range from <517 to <17,500 mg kg −1 (Basunia and Landsberger, 2001;Johnson et al., 2005;Kilgour et al., 2008;Knechtenhofer et al., 2003;Mitsunobu et al., 2006;Okkenhaug et al., 2013;Spuller et al., 2007), alth...

“…There was also a significant correlation (r 2 = 0.789, p < 0.01) between the concentration of As and that of Sb. This is not surprising given that the geochemical behaviour of As and Sb is rather similar (Crecelius et al, 1975;Tighe et al, 2005).…”

The impoundment located near the village of Poša in eastern Slovakia is a significant source of arsenic. Waters penetrating the impoundment become enriched in As and other potentially toxic elements. As a consequence, the Kyjov brook and the Ondava River have been extensively polluted by arsenic. Although, zinc is of minor environmental significance regarding pollution in the area, it was also monitored to compare its behaviour with that of arsenic. The mobility and solid-state distribution of As and Zn in the impoundment materials and stream sediments have been investigated using a five-step sequential extraction procedure. Moreover, to investigate the bioavailability of As and Zn, two native plant species (Typha latifolia and Phragmites australis) growing at the site were collected and analyzed. The As concentrations in representative sediment and water samples ranged from 36.28 to 3208.35 mg kg -1 and from 4.05 to 612.8 μg l -1 , respectively, both being many times above the background levels. The Zn concentrations of environmental importance were found to be high only in the impoundment materials (up to 3390 mg kg -1 ). Although a part of As was present in a readily soluble form (6.62%), the majority of As was mainly associated with Fe/Mn oxides (37.30%) and residual phases (51%). Similarly, the most dominant fractions for zinc distribution were Fe/Mn oxides (38.5%), residual (34%) and exchangeable (18%). Combined results of the sequential extraction tests as well as chemical and mineralogical analysis indicated that As mobilisation potential from the sediments is likely controlled by Fe/Mn oxyhydroxide mineral phases. Plants growing in the impoundment had As concentrations 10 to 100 times higher than the same plants growing in a relatively nonpolluted area, indicating an enhanced bioavailability of arsenic in the area with high total As contents in the impoundment materials. Odkalisko, ktoré sa nachádza pri obci Poša (východné Slovensko), je významným zdrojom arzénu. Vody presakujúce cez materiál uložený v odkalisku sa tak obohacujú o As a ďalšie potenciálne toxické prvky. Dôsledkom je výrazné znečistenie toku Kyjov a rieky Ondava arzénom. Aj keď v tejto oblasti zinok nepredstavuje až tak veľký environmentálny problém, je zahrnutý v tejto štúdii s cieľom porovnať správanie sa týchto dvoch potenciálne toxických prvkov. Na štúdium pohyblivosti a distribúcie As a Zn v materiáloch odkaliska a v riečnych sedimentoch sa použila päťkroková sekvenčná extrakcia. Okrem toho sme skúmali bioprístupnosť As a Zn v dvoch typoch rastlín (Typha latifolia a Phragmites australis), ktoré prednostne rastú na odkalisku. Koncentrácie As v odobratých vzorkách sedimentov boli v intervale od 36,28 do 3208,35 mg kg -1 a v povrchových vodách od 4,05 do 612,8 μg l -1 . Tieto koncentrácie sú oveľa vyššie ako pozaďové hodnoty pre danú oblasť. Bolo zistené, že koncentrácie Zn významné z hľadiska znečistenia sú vysoké len v odkaliskových materiáloch (až 3390 mg kg -1 ). Aj keď určitý podiel As v sedimentoch bol prítomný v ľahko rozpustnej ...

“…Mercury usually is present in uncontaminated marine and estuarine sediments at a concentration of 0.2 Fg/g dry weight or lower (Crecelius et al, 1975;Salmons and Förstner, 1984) except in areas, such as the East Pacific Rise and the Mid-Atlantic Ridge, where there are natural mercury-containing heavy minerals, such as cinnabar (Jonasson and Boyle, 1972). The "high" concentration of mercury in coastal sediments sampled in the National Status and Trends Program is 0.22 Fg/g (Table 9.33).…”
