The occurrence and mobility of natural radioactive element as 210Polonium (210Po) in 13 commercial algae consumed in Italy by humans was determined because the effects on human health need to take into account the bioavailability of these elements. The simulation of gastrointestinal (GIT) digestion was divided into three stages and was accomplished using three different artificial solutions: saliva, gastric as well as synthetic bile–pancreas solution. The same sample was treated in two different ways: a) only gastric digestion and b) complete GIT digestion (gastric digestion followed by bile-pancreas solution). The difference between Po gastric mobility with respect to that found for GIT digestion was not significant, in fact, Po mobility exhibited a mean value 17.2 ± 15.1% and 19.5 ± 11.5% for gastric and GIT digestion respectively.

Abstract
The occurrence and mobility of natural radioactive element as 210Polonium (210Po) in 13 commercial algae consumed in Italy by humans was determined because the effects on human health need to take into account the bioavailability of these elements. The simulation of gastrointestinal (GIT) digestion was divided into three stages and was accomplished using three different artificial solutions: saliva, gastric as well as synthetic bile–pancreas solution. The same sample was treated in two different ways: a) only gastric digestion and b) complete GIT digestion (gastric digestion followed by bile-pancreas solution). The difference between Po gastric mobility with respect to that found for GIT digestion was not significant, in fact, Po mobility exhibited a mean value 17.2 ± 15.1% and 19.5 ± 11.5% for gastric and GIT digestion respectively.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
