“…Based on previously described methods, [23][24][25][26] the following procedure was used to extract the cytosol from the selected tissues of exposed T. fluviatilis. About 0.1 g of hepatopancreas and gills from each specimen was homogenized using 10 mL 0.05 mol L -1 TRIS (tris(hydroxymethyl)aminomethane) (pH 7.0 and 4 o C) in 30 mL centrifuge tubes.…”

“…The procedure used for Cd fractionation on cytosols was the same as proposed by Menegário et al, 23 where the baker yeast Saccharomyces cerevisae is used as sorbent material to separate Cd(II) and Cd-P (possibly Cd metallothioneins or Cd bound to other proteins) from cytosols of biological extracts. After contact with the yeast and centrifugation, the inorganic fraction of cadmium (Cd(II) or "free" Cd) is expected to be found in solid phase (retained by the yeast) while the Cd-P is expected to be found in the liquid phase.…”

“…They were followed by the atomic (absorption or emission) spectrometries (Amorim and Bezerra 2007;Barbosa et al 2007a;Bezerra et al 2006b;Brasil et al 2005;Dorea et al 2007;dos Santos et al 2007b;Lima et al 2004;Menegario et al 2007;Oliveira et al 2005;Arruda 2004, 2005;Sella et al 2004). Mass spectrometry, coupled to gas chromatography (GC-MS), or liquid chromatography (LC-MS) either by ICP or APCI ionization sources, was the hyphenated technique employed in about 14% of the research papers computed (Barreto et al 2007;Dorea et al 2007;Duarte et al 2007;Rodriguez et al 2006;Titato and Lanças 2006;Buchmann et al 2006), followed by the electro analysis De Souza 2007;Simõ es et al 2006;De Souza 2005) and liquid chromatography (Brondi and Lanças 2004;Brondi et al 2005;Melo et al 2004;Titato and Lanças 2005), which were, each one, the applied techniques in 8% of the works done.…”

“…O micro-organismo foi utilizado com sucesso na determinação seletiva de espécies de As, Cr, Hg, Sb, Se e Cd. [24][25][26][27][28][29][30][31] Nestes métodos, o As(III), Cr(III), metilmercúrio, Sb(III), Se(IV) e Cd(II) na presença de As(V), Cr(VI), Hg(II), Sb(V), Se(VI) e Cd-metalotioneina, respectivamente, foram quantitativamente (e seletivamente) retidos pela levedura. O micro-organismo também foi utilizado para determinação de Sn(II) e Sn(IV).…”
