Atmospheric deposition of toxics onto the Seine Estuary, France: example of polycyclic aromatic hydrocarbons
Description (Dublin Core)
Concentrations of Polycyclic Aromatic Hydrocarbons (PAH) were measured in precipitation samples on a weekly basis between March and October 2001, at four sites in the Seine Estuary (France). Mean concentrations of total PAHs (<font face="Symbol" >S</font> 14 PAHs) ranged from 38 to 141 ng L<sup>-1</sup>. Fluoranthene, phenanthrene and pyrene were the dominant PAH compounds and were detected in each sample. The six potential carcinogenic PAHs accounted for 20 to 25% of the total PAH concentration in bulk deposition. The PAH signatures in bulk (wet and dry) deposition and surface water were also compared to investigate source/sink relationships. Seasonal patterns were observed with maximum loading occurring during the colder months of the studied period (March and April). Mean values of daily flux reported for <font face="Symbol" >S</font> 14 PAHs ranged from 108 to 267 ng m<sup>-2</sup> d<sup>-1</sup>. Spatial influences were also observed, indicating both localized and long-range atmospheric source inputs (controlled by hydroclimatic parameters).
