“…Again, the respective research activities were widespread, exhibiting all the significant features described in the previous paragraphs. The field has absorbed again several new users and propagators, involving scientists in European countries come from Lithuania [170] and Croatia [182]; with new teams having started in France [168] and Poland [191]. Worldwide, two new groups began in the USA (Tennessee [179]) and Brazil (Sao Paulo [169]), and for the first time in Africa (Morocco [185,186]), while the most abundant representation was strengthened in China [174,180,181,183,184], and the list of newcomers can be completed with one physicochemical group from neighboring Thailand [178].…”

“…Popular determinations of Zn(II), Cd(II), and Pb(II) are now demonstrated on the samples of natural or industrially treated waters [168,171,174,178,180], wine [169], canned food [186], and -for the latter -in seawater [184], gun-shot residues [167], or in monitoring of possible leakage from traditional ceramic cookware [185]. Further metal ions and species then are: Tl(I) in spiked model solutions [191], Sn(II) in canned fruit juices [188], Sb(V/III) in river and seawater [189], Co(II) in river water [175], Cr(VI) in dissolved polypropylene and sewerage [181], Ti(IV) in model solutions [173], V(V) in river water [179], and Te(IV) in natural water [187]. Finally, analytes of organic and biological origin are again of minor concern, represented by a series of herbicides (Metamitron, Metribuzin, Maleic Hydrazide, and Atrazine [165]), or pharmaceuticals from the family of aminosalycilate drugs (Sulfasalazine and Olsalazine [182]).…”

In this article, the decade of electroanalysis with bismuth-based electrodes is reviewed (with 222 refs.). Emphasis is put on the environmentally friendly ("green") character of bismuth electrodes, their versatility and variability in use, as well as the actual classification of the individual types of electrodes, sensors, and detectors that utilize the unique properties of metallic bismuth. Of particular interest is the genesis of the field, when the respective activities and achievements are monitored year by year over the whole period of 2000 -2009, including the circumstances of the introduction of bismuth-coated electrodes into electrochemical stripping analysis. The review highlights all the significant milestones and break-points that had directed the experimental work around the globe, outlining the present days position of this lively, inspiring, and still highly prospective area. Finally, it provides a special insight into electroanalysis with bismuth electrodes through numerous surveys, summaries, and detailed statistical data obtained by analyzing the accessible literature database.

“…Acetic acid at various concentrations was recommended in order to determine the exchangeable and carbonate-bound chromium fraction in the soil (Lillengen and Wibetoe 2002; Krasnodębska-Ostręga et al 2009). The amount of native chromium extracted from natural soil with 0.43 mol L −1 solution of CH 3 COOH was very low (<0.3%).…”

“…The behaviour of metals in soil and uptake by plants is controlled by element speciation and by soil properties, such as pH, particle size, cation-exchange capacity, content of organic matter, content and type of clay minerals and Al, Fe and Mn oxides, redox potential and microbiological activity (Kotaś and Stasicka 2000; Dhal et al 2013; Krasnodębska-Ostręga et al 2009; Paldyna et al 2013). Chromium(III) in soil is mostly present as insoluble chromium(III) hydroxide and tends to be adsorbed on the soil surface in a pH range of 4–8.…”

A critical appraisal of single-step extraction procedures of chromium species from soil was done in terms of their selectivity towards Cr(III) and Cr(VI) species. Samples of natural mineral and organic soil and samples of soil enriched with different chromium compounds of various solubility (in liquid or solid form) were used to simulate contamination of soil by liquid and solid wastes. The efficiency of extraction of Cr(III) and Cr(VI) species with various reagents, e.g. acetic acid, chelating agents (EDTA, DTPA) or inorganic salts (phosphates and carbonates), was evaluated on the basis of recovery results obtained for enriched samples. None of used reagents allow for quantitative extraction of added Cr(III) form. Procedures based on extraction of soil with Na2CO3 at room and elevated temperature (90–95 °C) were suitable for extraction of Cr(VI) species from mineral soil, whereas for organic soil, the procedure based on extraction with Na2CO3 at room temperature was recommended. The developed extraction procedures were validated using certified reference material (CRM 041 soil) and applied for analysis of contaminated soil samples. The studies showed that the physical state of waste, initial form and oxidation state of chromium and soil properties influenced the final chromium species and their mobility in soil, which have an impact on contamination of environment. The analysis of contaminated soil samples from a tannery area showed that the share of Cr(VI) was very low (only 0.8–4.5%) despite the high total content of chromium, which confirmed that chromium was present in immobile forms.

“…Outrossim, apresentam boa precisão, boa reprodutibilidade dos filmes formados, melhor sensibilidade e seletividade para diversos cátions metálicos. 6 Outra característica dos BiFEs, de alta relevância, é não responderem ao oxigênio, podendo ser aplicados em determinações in loco, uma vez que não há a necessidade de se utilizar nitrogênio para a desoxigenação da solução.…”
