Potentially harmful elements (PHEs) are supplied to estuarine environments by freshwater inputs affected by anthropogenic sources. This work aims at the evaluation of PHEs (Pb, Hg, Cs, As, Zn, Cu, Ni, Co, Fe, Mn) partitioning among suspended particulate matter, retentate and permeate fractions in the river mouths of the Gulf of Trieste (Isonzo, Timavo and Dragonja rivers). Significative concentrations of PHEs were detected in the particulate and dissolved fractions and to a certain extent PHEs were associated to the retentate fraction. PHEs showed a non-conservative behavior and salinity gradient appear to have an important role in their mobility and partitioning.

Abstract

Potentially harmful elements (PHEs) are supplied to estuarine environments by freshwater inputs affected by anthropogenic sources. This work aims at the evaluation of PHEs (Pb, Hg, Cs, As, Zn, Cu, Ni, Co, Fe, Mn) partitioning among suspended particulate matter, retentate and permeate fractions in the river mouths of the Gulf of Trieste (Isonzo, Timavo and Dragonja rivers). Significative concentrations of PHEs were detected in the particulate and dissolved fractions and to a certain extent PHEs were associated to the retentate fraction. PHEs showed a non-conservative behavior and salinity gradient appear to have an important role in their mobility and partitioning.
