“…Several studies have reported the concentration and toxicity of cadmium in shrimps (Páez-Osuna and Ruíz-Fernández, 1995b;Páez-Osuna and Tron-Mayen, 1996;Vanegas et al, 1997;Soegianto et al, 1999;Pourang and Amini, 2001;Kargin et al, 2001;Pourang et al, 2004;Wu and Chen, 2004;Seebaugh et al, 2005;Santos et al, 2013). The Cd concentrations in the shrimp body depend mainly on their levels in the environment since this element is not essential in the biochemical and physiological processes of this animal (Ruelas-Inzunza and Páez-Osuna, 2004).…”

In this study, concentrations of trace elements in tissues of shrimp species (Litopenaeus vannamei) from farming and zone natural coastal located in the northeastern Brazil were investigated. The elements determination was performed by optical emission spectrometry with inductively coupled plasma (ICP OES). The following ranges of concentrations in the tissues were obtained in µg g -1 dry weight: Al: 13. . The shrimp muscle can be a good iron source (about 88.9 mg -1 g dry weight). The distribution of Se concentration in tissues showed much variation between locations, and the concentration levels found in shrimp muscles of wild samples were high, where its levels in 67% of muscle and 50% of others tissues samples exceeded the ANVISA limit, indicating evidence of selenium bioaccumulation. Distribuição de elementos traço em tecidos do camarão Litopenaeus vannamei (Boone, 1931) da Bahia, Brasil ResumoEsse estudo teve como objetivo avaliar as concentrações de elementos traço em tecidos da espécie de camarão Litopenaeus vannamei coletadas da zona costeira e de carciniculturas localizadas no nordeste do Brasil. Os elementos químicos foram determinados por espectrômetro de emissão óptica com plasma indutivamente acoplado (ICP OES). Foram encontradas as seguintes faixas de concentrações desses elementos nos tecidos (em mg g -1 peso seco): Al: 13,4-886,5; Cd: 0, 80; Cu: 24, Fe: 3, Mn: 0,4; Se: 0,81 and Zn: 20,4. O músculo do camarão investigado pode ser uma boa fonte de ferro (cerca de 88.9 mg-1g peso seco). A distribuição da concentração de Se nos tecidos apresentou muita variação entre as localidades, com níveis acima do estabelecido pela ANVISA para 67% dos musculos e 50% dos outros tecidos investigados, indicando evidências de bioacumulação do selênio. Houve correlações significativas entre os seguintes pares de elementos:: Fe-Zn (r= -0,70), Mn-Cu (r= -0,74), Se-Cu (r= -0,68), Se-Mn (r= 0,82) nos músculos, Fe-Al (r= 0,99), Mn-Al e Mn-Fe (r= 0,62), Se-Al (r = 0,88), Se-Fe (r= 0,87), Se-Mn (r= 0,58) no exoesqueleto e Cu-Zn (r = 0,68), Al-Cu (r= 0,88), Fe-Cu (r= 0,95) and Fe-Al (r= 0,97) nas vísceras.Palavras-chave: Baia de Todos os Santos, camarão, elementos traço, bioacumulação, ICP OES.

“…Therefore, it can be said that a well-chosen adsorbent determines the efficiency of the SPE technique. Amberlite 2 Journal of Chemistry XAD5 resins which are able to adsorb metal complexes have received a great deal of attention because of versatile usage with or without derivatization [19][20][21][22]. In particular, Amberlite XAD-7 resin possessing an intermediate polarity and hydrophilic surface as a highly crosslinked macroreticular acrylic resin (polyacrylic acid ester polymer) has been performed in SPE studies [23][24][25].…”

A new procedure for separation and preconcentration of trace amounts of Cu(II), Ni(II), Fe(III), Zn(II), Cr(III), Cd(II), and Pb(II) in fish samples was proposed. The procedure is based on the adsorption of these metal ions on the column of Amberlite XAD-7 as congo red complexes prior to their determination by flame atomic absorption spectrometry (FAAS). Several factors that can affect the sorption and elution efficiency of the metal ions were investigated and optimized. The sorption was quantitative in the pH range of 6.0-9.0 for Cu(II) and Ni(II), 5.5-8.0 for Fe(III), 6.0-8.5 for Zn(II) and Cd(II), and 7.0-8.5 for Cr(III) and Pb(II). The optimum pH for simultaneous retention was 7.5. The sorption capacity of the resin was found to be 0.89, 0.72, 0.82, 0.61, 0.53, 0.84, and 0.78 mg/g for Cu(II), Ni(II), Fe(III), Zn(II), Cr(III), Cd(II), and Pb(II), respectively. The precision of the method was evaluated as the relative standard deviation obtained by analyzing a series of six replicates and below 6% for all seven elements. The validation of the method was performed by the analysis of certified reference materials. The proposed method was successfully applied to separation/ preconcentration and determination of these metals in fish samples.
