Sažetak
Coastal environments are known to be strongly influenced by various continental inputs, leading to potential increase in the different environmental compartments (water column, sediment, biota, …) of inorganic (e.g. metals, metalloids, …) and organic (e.g. PAH, PCB, pharmaceuticals, …) contaminants which are naturally present at trace or ultra-trace levels. Among all these possible sources of marine pollutions, large coastal cities impact is one of the most worrying, especially in the Mediterranean Sea, due to the rapid population increase all around the coasts. These inputs, partly diffusive and strongly linked to weather conditions (e.g. episodic intensive rain events leading to important urban/industrial land weathering) have to be carefully studied to be compared to other contaminant sources as large river or atmospheric inputs. In such context, the evaluation of trace metals dynamic and fate in coastal environments is a complex issue, which needs the use/development of numerous sampling, analytical, experimental and modelling tools. The present talk will be illustrated by recent results obtained in the framework of different research programs (MARSECO, GIRAC-PACA, CARTOCHIM, PHC COGITO, …) in 3 contrasted Mediterranean coastal areas: (1) the Marseille (France) bay, a large agglomeration directly connected to the open sea, (2) the Toulon bay (France), a semi-closed area presenting an important contamination of its sediments and (3) the Krka river estuary (Šibenik bay, Croatia), a stratified and oligotrophic estuary with ultra- trace levels of metals except in summer due to significant inputs from nautical activities (e.g. antifouling paints).
