Description: The loadings and fate of two metals and three persistent organic pollutants were evaluated in the Venice Lagoon using a multi-segment fugacity/aquivalence model. Erosion and in-place pollution of the central basin of the Lagoon were considered, and metal chemistry was respected through utilization of a loosely coupled TRANsport-SPECiation model. In-place pollution, industrial sources and tributaries were identified as major sources of these contaminants. Contaminants circulated extensively between the northern and central basins with limited transport to the southern basin and the Adriatic Sea. Model uncertainty was evaluated using a probabilistic approach to evaluate the effects of parametric uncertainty associated with particle dynamics. The range of model output distributions were found to vary up to an order of magnitude, exhibiting both contaminant- and site-specific variability. Sediment erosion and total suspended sediments were identified as the parameters most responsible for model uncertainty using a principal component analysis in combination with a correlation matrix.
