| Abstract: | Sediments from different environments of an area directly affected by the discharge of the Po River and 13 other minor rivers
have been studied. Three main sources of metals and several distribution mechanisms can be identified. Concentration profiles
of metals in a core allow one to establish background levels of finegrained sediments for Cd, Hg, Pb, and Zn Seabed sediments
do not appear to be very polluted, mainly because of desorption and dilution processes |
