“…The key words used were "bioaccessibility", "Brazil", "soil" and "sediments". Of these 13 papers, one was carried out with soils from state of São Paulo , Souza et al, 2018, one with soils from Amazon forest (Moreira et al, 2018), one with soils of the city of Três Marias, Minas Gerais state (MG) (Ono et al, 2016), two articles and three procedures with soils of Paracatu, MG (Ono et al, 2012a, b;Guilherme et al, 2014;Ng et al, 2014a, b, Ciminelli et al, 2018, two articles with soils from Adrianópolis, State of Paraná (Bosso & Enzweiler, 2008a;Bosso et al, 2008) and a review (Bosso & Enzweiler, 2008b). While around 350 articles and 13 international reviews were found at the Scopus research base, most of them were published by Chinese, American and British researchers.…”

“…(Fergusson, 1990;USEPA, 1997;Rodella, 2005). Entretanto, esse quadro está sendo gradativamente alterado com a produção de material de referência de fertilizantes para concentrações maiores, menores e de elementos traços (Mackey et al, 2007;Nogueira et al, 2015 (Iyengar et al, 1997;Rodriguez et al, 2011;Kaiser et al, 2012;Losfeld et al, 2015;Mesko et al, 2016;Taylor et al, 2016). Os elementos metálicos, metaloides e não metálicos, nas formas iônica, livres ou associados a outras espécies químicas, estão presentes nos sistemas biológicos e desempenham importantes papéis na manutenção do bom funcionamento dos organismos vivos (Iyengar et al, 1997;Marschner, 2011 (Iyengar et al, 1997;Goyer, 2013;Tian et al, 2015).…”

In order the facilitate the growth of the Brazilian fishery production, in a sustainable way, it is necessary to develop sound scientific and technological base to address the existing demands in the various links of the production chain. One of the main evidences of the products' quality is provided by the analytical results, whose reliability and accuracy can be assured by the use of reference materials (RM). In this context, it was produced a RM of fish feed for macro-and micronutrients and proximates analysis. Also, a RM of fish tissue, which is in its final stage of development, for nutrients and inorganic contaminants. The production of reference materials followed the ISO Guides 30-35 standards: preparation and packaging, irradiation, minimum sample, homogeneity, short-and long-term stability, and material characterization. The materials were acquired from commercial suppliers. The materials were dried/freeze-dried, pulverized, homogenized and aliquoted into amber glass bottles. The bottles were gamma irradiated to a minimum dose to inhibit bacterial action. Characterization of the candidate fish feed RM was performed through a round robin exercise. The study of minimum sample mass, homogeneity and stability of the material were performed using inductively coupled plasma optical emission spectrometry (ICP-OES). Results from sub-samples (250 mg) were evaluated and it was verified that the fish feed proposed RM could be considered homogeneous for Ca, Cu, Fe, Mg, Mn and Na, as no significant difference in significance level of 0.05 was observed. Long-term stability study of this proposed RM was performed by the residual analysis in regression and ANOVA and the short-term stability study was performed by simple linear regression. This proposed RM could be considered sufficiently stable to be stored at room temperature. The data obtained along the production and through the round robin exercise allowed the characterization of the fish feed RM as well the determination of uncertainties components. For the proposed RM of fish tissue, Inductively coupled plasma mass spectrometry (ICP-MS) was also used for the assessment of homogeneity and short-term stability. Results from sub-samples (250 mg) were evaluated and considered homogeneous and stable to be transported under temperature below 37ºC.
