| Abstract | The 2021 monitoring campaign for chemical contamination established a baseline for PFAS concentrations in mussels along the French Mediterranean coast. Ninety percent of the targeted PFAS measurements were below quantification limits, and no data exceeded the few guiding values available for bivalves. Long-chain PFCA's were confirmed as predominant in mussels. Spatial distribution patterns revealed continuous inputs and complex dynamics of PFAS distribution in the marine environment. Lapeyrade lagoon appeared to be the most contaminated site. Similar PFAS profiles in connected sites suggested shared sources but raised questions about accumulation processes in mussels. Some watersheds and rivers (Rhône, Aude, Huveaune) influenced PFAS distribution. Certain sites had obvious sources (e.g. military airbase for Palo lagoon), but others posed uncertainties (e.g., Toulon bay). Coastal stations (Banyuls, Cap Agde, Brégançon, Pampelonne) exhibited PFAS contamination without clear onshore sources, possibly due to insufficient information on transportation processes. |
