“…The selenium concentrations found in the muscles of shrimps analyzed are similar to the values obtained in other studies conducted with shellfish and benthic species with similar life habits elsewhere in the world (May et al, 2001;Peterson et al, 2002;Harding et al, 2005).…”

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.

“…Human activities such as mining, agriculture, and industrial production of pigments, glasses, and electronic devices have contributed to accelerate the mobilization of selenium, whose concentration in ground waters and soils has increased during the last decades in specific setups (Ong et al 1997;Ryser et al 2006). In fact, selenium has recently been identified as a major contaminant in aquatic ecosystems (Lenz and Lens 2008;May et al 2008). This element is also relevant in the context of nuclear waste management due to the high radiotoxicity of its long-lived isotope 79 Se (Jörg et al 2010).…”

The element selenium has become a considerable environmental concern due its accumulation in aquifers on the one hand and the high radiotoxicity of its long-lived isotope 79 Se on the other hand. Se(VI) is the most mobile of the various Se cations. This study deals with the interaction of Se(VI) with rock-forming minerals (carbonates) to better understand how to mitigate the potential environmental hazards of Se.The effect of Se(VI) on the cystallization of CaCO 3 at room temperature was studied using the silica hydrogel method. The CaCO 3 crystals obtained were characterized by X-ray powder diffraction, scanning electron microscopy and electron microprobe. The presence of Se(VI) in the growth medium has a clear effect on the polymorph selection of CaCO 3 , promoting the formation of vaterite and inhibiting that of aragonite. Se(VI) also affects the characteristics of calcite crystals, which show progressively more elongated habits and smaller sizes with increasing Se(VI) concentration in the growth medium. The effect of Se(VI) on both the polymorphic crystallization of CaCO 3 and the characteristics of calcite crystals shows features strikingly similar to those of other tetrahedral anionic groups like S(VI) and Cr(VI). This similarity extends to the amount of Se incorporated into the structure of the different CaCO 3 polymorphs, with calcite having Se contents up to 1200 ppm, vaterite up to 500 ppm, and aragonite growing virtually Se-free. The role of Se(VI) on the crystallization of CaCO 3 is discussed taking into consideration the physicochemical conditions in the growth medium at nucleation, which were modeled using the PHREEQ code for low-temperature aqueous geochemistry. The possible effect of the incorporation of the Se(VI) on the relative stability and, by extension, on the solubility of CaCO 3 polymorphs is also discussed.

“…In the USA, various anthropogenic activities have greatly increased the mobilization and transport of selenium into aquatic ecosystems. From the 1960s through the 1980s, selenium mobilization on a regional and national scale largely was a result of two causes: (1) procurement, processing, and combustion of fossil fuels and (2) irrigation of seleniferous soils for crop production in arid and semiarid regions (Lemly et al 1993;May et al 2001). A critical agricultural and environmental problem emerged in California's San Joaquin Valley in the 1980s when saline subsurface drainage waters from 17,000 ha of waterlogged croplands were impounded in the Kesterson Reservoir.…”

“…Toxicity and essentiality of selenium have been widely discussed by many authors (Sager 1994a, b;Peters et al 1997;Zhang et al 2003;Bujdos et al 2005;May et al 2008). The concentration of selenium in plants and animals is strongly correlated with its concentration in soils.…”

A two-dimensional finite element model was developed to simulate species of selenium transport in two dimensions in both saturated and unsaturated soil zones. The model considers water, selenate, selenite, and selenomethionine uptake by plants. It also considers adsorption and desorption, oxidation and reduction, volatilization, and chemical and biological transformations of selenate, selenite, and selenomethionine. In addition to simulating water flow, selenate, selenite, and selenomethionine transport, the model also simulates organic and gaseous selenium transport. The developed model was applied to simulate two different observed field data. The simulation of the observed data was satisfactory, with mean absolute error of 48.5 μg/l and mean relative error of 8.9%.
