A 3D hydrodynamic and contaminant fate model was implemented for polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in Thau lagoon. The hydrodynamic model was tested against temperature and salinity measurements, while the contaminant fate model was assessed against available data collected at different stations inside the lagoon. The model results allow an assessment of the spatial and temporal variability of the distribution of contaminants in the lagoon, the seasonality of loads and the role of atmospheric deposition for the input of PCDD/Fs. The outcome suggests that air is an important source of PCDD/Fs for this ecosystem, therefore the monitoring of air pollution is very appropriate for assessing the inputs of these contaminants.

Persistent organic pollutants (POPs) present in the airshed of a given environment may participate in exchange / deposition processes that will determine their inputs to the terrestrial or aquatic ecosystems. In addition, physico-chemical properties of POPs may favour long range atmospheric transport to other areas, even reaching remote zones. It is therefore important to determine the airshed POPs concentration in order to evaluate the potential amounts that may participate in the mentioned processes. Coastal lagoons are characterized by a high biodiversity and intense primary production leading to both ecological and economical considerable importance. Thau lagoon seems to be under intense anthropogenic pressure (urban, industrial, agricultural and shell... |
