Metal concentrations were determined in mussels (Mytilus galloprovincialis) collected in areas exposed to pollution sources; in the muscle tissues of hake (Merluccius merluccius), red mullet (Mullus barbatus) and sea bream (Pagellus erythrinus) from the eastern part of the Adriatic Sea (caught at 48 sampling stations) and in four fish species commonly caught in coastal and open waters of the eastern Adriatic Sea: anchovy (Engraulis encrasicholus), mackerel (Scomber japonicas), red mullet (Mullus surmuletus) and picarel (Spicara smaris). Organic contaminants were determined in mussels (Mytilus galloprovincialis). Radionuclides were measured in sardines (Sardina pilchardus), Musky octopus (Eledone moschata) and mussels (Mytilus galloprovincialis). Levels of contaminants do not exceed regulatory levels, except for Pb, but the frequency of exceeding regulatory levels for Pb was reduced to one for the last year, and is not affected to GES. GES is achieved.

Concentrations of Cd in mussels (Mytilus galloprovincialis) caught for human consumption in areas exposed to pollution sources, were below the maximum permitted levels listed in Commission Regulation No 1881/2006 and 629/2008; concentrations of Pb occasionally exceeded the maximum permitted levels, while increased Hg concentrations were measured in samples collected in the middle of the eastern part of the Adriatic Sea in an area which has been exposed to the activities of the chemical plant for the production and processing of vinyl chloride. Concentrations of Cd and Pb in the muscle tissue of hake (Merluccius merluccius), red mullet (Mullus barbatus) and sea bream (Pagellus erythrinus) from the eastern part of the Adriatic Sea (caught at 48 sampling stations) do not exceed the maximum permitted levels. The concentrations of Cd, Hg and Pb determined in four fish species commonly caught in coastal and open waters of the eastern Adriatic Sea: anchovy (Engraulis encrasicholus), mackerel (Scomber japonicas), red mullet (Mullus surmuletus) and picarel (Spicara smaris) were below the maximum permitted levels and indicate the good environmental condition along the eastern coast of the Adriatic Sea. Organic contaminants were determined in mussels (M. galloprovincialis). Organochlorine compounds (DDT, aldrin, dieldrin, lindane and HCB) showed decreasing trend; polychlorinated biphenyls (PCBs) were present at low levels and uniformly distributed during the investigation period. Concentrations of benzo(a)pyrene (PAH) were below the detection limits in mussels from 45 sampling stations. Concentrations of chrysene, benzo(b)flouranthene and benzo(a)anthracene in shellfish from 13 breeding area and 6 shellfish harvesting areas were below the limit of detection. The highest concentration of 137Cs were determined in indicator organisms sardines (Sardina pilchardus) 0.25 Bq/kg. Concentrations activity of natural radionuclide, 232Th (228Ra), 238U and 226Ra measured in mussels were extremely low and almost always below the detection limit. GES is achieved.
