“…They found that the organic matter content is a very important factor to be considered when using water samples. Similar studies were conducted by Ringmann et al (2002) for organoarsenic compounds present in waters, biological materials (algae, plankton, mussel tissue, scallops, and lobster) and river sediments. A combination of sodium persulphate, sodium fluoride and nitric acid was an ideal reagent to the quantitative transformation of these species into others forming hydrides using medium-and high-pressure vessels, providing the arsenic total determination by HGAAS.…”

“…High pressure bombs are commonly used tools in the wet digestion of biological samples in heavy metal determination (Farkas et al, 2002(Farkas et al, , 2003Ringmann et al, 2002). However, we have not found any references regarding the use of this method in P analysis of aquatic animal samples.…”

-High pressure and temperature were combined with the convenient mixture of acids to perform an effective digestion of samples from aquatic animals for phosphorus (P) analysis. Our results indicate that digestion in high-pressure bombs combined with concentrated acidic media can be a convenient way to yield all P stored in samples, and to produce accurate recoveries. Phosphorus recovery of a certified standard material (94% ¡ 15) and digestions of aquatic animal tissues confirmed the relevance of bomb decomposition, as well as its reliability compared to ashing and microwave oven digestion methods. Moreover, the applied digestion technique is easily manageable even in samples consisting of a few individuals. This method is relatively rapid, saves money and time, and is able to recover P from the most persistent components (e.g. bones, scales, fat) of aquatic animal tissues.

“…The analysis by suspension offers some advantages such as: shorter time for sample preparation, so reducing the possibility of contamination, decreasing loss by volatilization, lower reagent consuming and smaller amount of waste generated [43,47]. On the other hand, analysis by suspension also has disadvantages that brings errors such as homogeneity of particles in suspension [43,48], particle size [48], concentration of diluent, the nature of the analyte, among others.…”

Abstract:This review provides an overview and discusses different analytical strategies that minimize or eliminate the preparation of samples for speciation of organic and inorganic species of As, Cr and Se in samples of biological interest. These metals are important for the human body and the presence of various chemical forms of metals determines its essentiality and toxicity, thus speciation comes as an important tool for the study of biological samples. However, speciation requires a reduction in the steps of sample preparation, allowing a sample investigation in its most native form in order to reduce the changes in chemical species. The strategies proposed for speciation of these metals include: solid phase extraction, point cloud extraction, suspension and direct analysis. Selected methods proposed for the speciation of organic and inorganic species of As, Cr and Se were reviewed including their main figures of merit, advantages and disadvantages.
