The distribution of total arsenic in different portions of Norway lobster (Nephrops norvegicus L, Crustacea) was studied both in fresh samples and after a boiling process. All individuals (n = 80) were selected of medium standard commercial size (13-15 cm). The highest mean concentrations (26.86 ± 1.57 mg/kg wet weight) were found in the raw brown meat of the crustacean, probably due to its detoxification role, while the lowest mean values (15.97 ± 0.85 mg/kg wet weight) were in the raw exoskeleton. The raw white meat reported mean values of 16.09 ± 0.61 mg/kg w.w. The levels of arsenic contamination detected in the boiled portions showed a significant (p < 0.01) decrease compared to the raw portions, as a consequence of solubilization phenomena. In fact, a large amount of arsenic from raw lobsters was transferred to the corresponding boiling broth. In the most common consumed portion, the white meat, only few losses (7.22 %) in total arsenic content were observed compared to the raw portion.
