Evaluation of the boundary condition influence on PAH concentrations in the water column during the sediment dredging of a port
Description
The mobilisation of sediments and related contaminants connected to dredging activities is one of the most critical
issues to the environmental risk and exposure assessment of a dredging project. The aimof this paperwas an
investigation of the mobilisation of polycyclic aromatic hydrocarbons (PAHs) due to the dredging of the Port of
Genoa (Italy) to identify the temporal and spatial extent of the contaminant transport, and the influence of the
dredging and the boundary conditions on it. The results showed relatively low background PAH concentrations
in the water column and confirmed the dredging as the primary rising factor of concentrations in the water
column, but also showed a complex scenario in which the different environmental and dredging factors forced
the concentrations at different levels and moments. The post dredging phase showed PAH values close to the
background conditions and the concentrations remained relatively high only for a few PAHs.
