Abstract
Commercial fishes and mussels were collected in the Northern Adriatic Sea and analysed for total methyl mercury content. Total and methyl mercury were found to be present in all samples. The average total mercury concentrations in sardine, conger-eel, tuna and Mediterranean mussel were 170.0, 570.0, 1730.0 and 56.0 µg/kg respectively. Gas chromatography determination of methyl mercury showed average concentrations in sardine, conger-eel, tuna and Mediterranean mussel to be 20.6, 100.0, 225.0 and 15.7 µg/kg respectively. Total and methyl mercury concentrations were below the tolerance limit except for total mercury content in the tuna muscle tissue (1730 µg/kg).
