As of today, and upon standardization of the methodological approach, the MMW Network has been able to quantify Cs-137 levels in mussels from 60 coastal stations and to produce the first distribution map of this artificial radionuclide at the scale of the entire Mediterranean and Black Seas. While: measured Cs-137 levels were found to be very low (usually <1 Bq kg(-1) wet wt) Cs-137 activity concentrations in the Black Sea and North Aegean Sea were up to two orders of magnitude higher than those in the western Mediterranean Basin. Such effects, far from representing a threat to human populations or the environment, reflect a persistent signature of the Chernobyl fallout in this area. (C) 2007 Elsevier Ltd. All rights reserved.
