ResumoThe temporal variations of polycyclic aromatic hydrocarbon (PAH) concentrations demonstrate that the inputs to the sediments have increased considerably in the Saguenay Fjord, Québec, especially since 1930. However, a decrease in the concentrations in the Fjord sediments was noted for the last decade, but it was not observed in the sediments of Baie des Ha! Ha! The data indicate that the Saguenay River is a main route of entry of PAH to the Fjord system. The calculated PAH fluxes reveal that a great portion of the PAH, released in the Saguenay hydrographic basin, is not incorporated in the Fjord sediments. The spatio-temporal behavior of PAH in the sediments suggests that the major source of PAH in the Saguenay area originates from two aluminum reduction plants located upstream of the Saguenay Fjord.
