Abstract

A survey was conducted to determine the total mercury content in fish available on the market or fished in the port of Genoa (Italy). Determinations were made with a variation of the flameless atomic absorption method. The tinned tuna showed high levels of mercury in Parathunnus obesus and Tunnus thynnus fished in the Mediterranean. Neothunnus macropterus and Katsuwonus pelamis had lower levels than in the same species of fresh fish. Mercury contents of tinned anchovies, sardines and mackerel were highest in Engraulis encrasicholus fished in the Adriatic sea and the lowest in the Clupea sardina compared to an average amount in Scomber scomber.
