Applicability of an in vitro gastrointestinal digestion method to evaluation of toxic elements bioaccessibility from algae for human consumption.

This study aimed to investigate the bioaccessibility of toxic elements, including aluminum (Al), arsenic (As), nickel (Ni), cadmium (Cd), and lead (Pb) in five commercial algae consumed by humans in Italy. The degree of bioaccessibility of these elements may have important implications for human health. Simulation of gastrointestinal tract (GIT) digestion was divided into three stages through use of synthetic saliva, gastric, and bile-pancreas solutions.

Elemental and radiological characterization of commercial Cetraria islandica (L.) Acharius pharmaceutical and food supplementation products.

An elemental and radiological characterization was performed on Cetraria islandica (L.) Ach. pharmaceutical and food supplementation products purchased in local specialty shops in Italy.

Application of an in vitro digestion model for Po bioaccessibility assessment in seafood.

This study aims to investigate the bioaccessibility of Po in seafood and the impact of food preparation on this radionuclide. Polonium bioaccessibility is the fraction of Po mobilised from food matrices into digestive extractants when applying an in vitro digestion model. The degree of bioaccessibility of Po in food has important implications for estimating ingestion doses from this radionuclide.

Radioactivity measurements and dosimetric evaluation in meat of wild birds.

The aim of this study was to determine the background activity concentration of natural radionuclides and Cesium (Cs) in meat of 14 migratory birds originating from central and northern Europe. This meat is largely consumed by the Italian population. K, Pb, and Cs were determined by gamma spectrometry and Po by alpha spectrometry.
