Assessment of heavy metal contamination and mineral magnetic characterization of the Asopos River sediments (Central Greece)

► Magnetics help to identify compositional alterations of particles across the system. ► Labile metal species accumulate in the estuary. ► Changes in metal speciation in shallow, organic rich estuarine “pools”. ► High energy conditions “remove” occasionally coarse particles to the sea. ► Low energy conditions “remove” regularly very fine particles to the sea.
