Benthic fluxes of dissolved heavy metals and nutrients in polluted sediments of the Adriatic Sea

Nel poster è riportata l’attività della sub-task 2.3.4 del progetto Perseus. L’obiettivo è quello di determinare i flussi bentonici di metalli pesanti e dei nutrienti disciolti dai sedimenti soggetti all’influenza degli ingressi del fiume Po e di valutare il ruolo dei sedimenti nella contaminazione e l’eutrofizzazione della colonna d’acqua del Mar Adriatico occidentale.

In the poster the activity of the sub-task 2.3.4 of the PERSEUS project is reported. The aim is to determine the dissolved benthic fluxes of heavy metals and nutrients in sediments affected by the Po River inputs and to evaluate the role of sediments in the contamination and eutrophication of the western Adriatic Sea water column.

In order to measure dissolved pollutant fluxes at the sediment-water interface two cruises have been carried out in spring and autumn 2013. Sampling stations are located along a south-eastward pollution gradient. In each station one benthic chamber has been deployed for 8-24 hours. During the spring cruise benthic fluxes have been measured in five stations while in autumn cruise benthic flux measurements have been performed only in two stations due to bad weather conditions. In autumn stations, also early diagenesis studies have been carried out to understand the biogeochemical processes that generate the observed benthic fluxes.
