Concentrations of selected metals and organic contaminants in mussels in the north-east Atlantic Ocean (A), Mediterranean Sea (B) and herring (muscle) for the Baltic Sea (C).
Aggregated data do not necessarily convey the uncertainty these problems cause. A minimum of 10 mussels and 3 herring stations were used. *)Comparisons are based on average of yearly regional and adjusted medians for the indicated time periods. For the 1990-1992 period for DDT in mussels from NE Atlantic there is only data from 1992.
Geographical coverage note: Nort-east Atlantic Ocean, Baltic Sea, Mediterranean Sea
