Effects of common cooking heat treatments on selenium content and speciation in garlic
(Academic Press Inc Elsevier Science, 2018-07)
The effect of traditional thermal treatments, normally applied during cooking practices, on the stability of Se-amino acids and Se-proteins present in Se-enriched garlic was studied. Five heat treatments including, convection ...

(Universidad Nacional del Litoral, 2019-10)
Online solid phase extraction-HPLC-ICP-MS system for mercury and methylmercury preconcentration using functionalised carbon nanotubes for their determination in dietary supplements
(Royal Society of Chemistry, 2018-10)
A hyphenated system was developed for Hg(ii) and methylmercury (MeHg) preconcentration and speciation analysis by the online coupling of solid phase extraction (SPE), high performance liquid chromatography (HPLC) and ...
Arsenic in Argentinean polished rice: situation overview and regulatory framework
(Elsevier, 2020-03)
The Codex Alimentarius has established a 200 μg kg-1 limit of iAs in polished rice grain, while the Argentine Food Code, in accordance with the Mercado Común del Sur (Mercosur), has set an advisory level of 300 μg kg-1 of ...
Atmospheric stability of arsines and the determination of their oxidative
(Royal Society of Chemistry, 2010-02)
Biovolatilisation of arsenic as their arsines in the form of AsH 3, and mono-, di and trimethylarsine has often been determined under laboratory conditions. Although environmental point sources such as landfill sites or ...
Inter‐and intra-stock bioaccumulation of anionic arsenic species in an endangered catfish from South American estuaries: risk assessment through consumption
(Academic Press Inc Elsevier Science, 2020-04)
Monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), inorganic arsenic (iAs), and non-toxic species (i.e. arsenobetaine) were determined by HPLC-ICP-MS as mg kg−1 wet weight in muscle, liver and gill of catfish (Genidens ...
Determination of inorganic arsenic in Argentinean rice by selective HGAAS: Analytical performance for paddy, brown and polished rice
(Academic Press Inc Elsevier Science, 2020-08)
Inorganic As (iAs) species require strict monitoring in foodstuff due to their toxicity. Rice is of particular concern, with recent legislations establishing limits for these species. In this work we develop a method based ...
