Extended evaluation of polymeric and lipophilic sorbents for passive sampling of marine toxins ArchiMer
Zendong, Zita; Herrenknecht, Christine; Abadie, Eric; Brissard, Charline; Tixier, Celine; Mondeguer, Florence; Sechet, Veronique; Amzil, Zouher; Hess, Philipp.
Marine biotoxins are algal metabolites that can accumulate in fish or shellfish and render these foodstuffs unfit for human consumption. These toxins, released into seawater during algal occurrences, can be monitored through passive sampling. Acetone, methanol and isopropanol were evaluated for their efficiency in extracting toxins from algal biomass. Isopropanol was chosen for further experiments thanks to a slightly higher recovery and no artifact formation. Comparison of Oasis HLB, Strata-X, BondElut C18 and HP-20 sorbent materials in SPE-mode led to the choice of Oasis HLB, HP-20 and Strata-X. These three sorbents were separately exposed as passive samplers for 24 h to seawater spiked with algal extracts containing known amounts of okadaic acid (OA),...

High resolution mass spectrometry for quantitative analysis and untargeted screening of algal toxins in mussels and passive samplers ArchiMer
Zendong, Suzie Zita; Mccarron, Pearse; Herrenknecht, Christine; Sibat, Manoella; Amzil, Zouher; Cole, Richard B.; Hess, Philipp.
Measurement of marine algal toxins has traditionally focussed on shellfish monitoring while, over the last decade, passive sampling has been introduced as a complementary tool for exploratory studies. Since 2011, liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been adopted as the EU reference method (No.15/2011) for detection and quantitation of lipophilic toxins. Traditional LC-MS approaches have been based on low-resolution mass spectrometry (LRMS), however, advances in instrument platforms have led to a heightened interest in the use of high-resolution mass spectrometry (HRMS) for toxin detection. This work describes the use of HRMS in combination with passive sampling as a progressive approach to marine algal toxin surveys. Experiments...

Position paper on passive sampling techniques for the monitoring of contaminants in the aquatic environment - Achievements to date and perspectives ArchiMer
Miege, Cecile; Mazzella, Nicolas; Allan, Ian; Dulio, Valeria; Smedes, Foppe; Tixier, Celine; Vermeirssen, Etienne; Brant, Jan; O'Toole, Simon; Budzinski, Helene; Ghestem, Jean-philippe; Staub, Pierre-francois; Lardy-fontan, Sophie; Gonzalez, Jean-louis; Coquery, Marina; Vrana, Branislav.
This paper, based on the outcome of discussions at a NORMAN Network-supported workshop in Lyon (France) in November 2014 aims to provide a common position of passive sampling community experts regarding concrete actions required to foster the use of passive sampling techniques in support of contaminant risk assessment and management and for routine monitoring of contaminants in aquatic systems. The brief roadmap presented here focusses on the identification of robust passive sampling methodology, technology that requires further development or that has yet to be developed, our current knowledge of the evaluation of uncertainties when calculating a freely dissolved concentration, the relationship between data from PS and that obtained through biomonitoring....

Recommandations pour garantir la qualité des données de surveillance par échantillonnage passif. Outils émergents ArchiMer
Ghestem, J-p; Togola, A; Lardy-fontan, S; Guigues, N; Tixier, C; Larose, A; Miège, C.
The report prepared up within the AQUAREF program for 2015 provides recommendations to ensure the quality of passive sampling monitoring data. This type of sampling method could in the future be used in regulatory monitoring, and it seems necessary to prepare the tools, procedure that will be able to ensure the reliability of such data. The report first proposes an organization of the chain of responsibilities between: * the customer, * a pilot in charge of contacts with customer, sampling operations and of the the final report * and the laboratory which would be in charge of the analytical part on the passive sampling tool transmitted by the pilot. This organization is considered as an example. Other organizations are possible, provided they specify the...

Simulated conservative tracer as a proxy for S-metolachlor concentration predictions compared to POCIS measurements in Arcachon Bay ArchiMer
Fauvelle, Vincent; Belles, Angel; Budzinski, Helene; Mazzella, Nicolas; Plus, Martin.
The work presented here aims at comparing monitoring of S-metolachlor, the major pesticide in use in the Arcachon Bay (South West of France, transitional coastal area), by chemical analysis (monthly passive sampling) and contaminant dissipation modeling from sources (Mars-2D model). The global strategy consisted in i) identifying the major sources of S-metolachlor to the Bay, ii) monitoring these sources for 12 months, and iii) comparing modeled data in the Bay based on measured inputs, to chemical measurements made inside the Bay along with the 12-month source monitoring. Results first showed that the major S-metolachlor surface inputs to the Arcachon Bay are mainly from one single source. Modeled and measured data were in good agreement at 5 sites in the...
