Ecological risk assessment of contaminated sediments in a harbour site


During major dredging operations in the harbour of Genoa, one of the largest in Italy, a monitoring study was carried out on the quality of marine sediment output, with a view to identifying possible pollutants engendering environmental and ecological risk. The concentration range of all the pollutants evaluated fell within acceptable limits. The only pollutant with concentrations approaching ecological risk levels was nickel. Differences in concentrations of pollutants were mapped and related to special- ized areas of harbour activity.
