[CEST2019_00720] Sources and transfer of Cu, Hg and Pb into marine food webs using innovative tracers (metal stable isotopes, trophic markers): results of a pilot study in a French coastal area
by Chouvelon T., Araujo F.D., Bouchoucha M., Briant N., Bruzac S., Crochet S., Knoery J., Ponzevera E., Rozuel E., Sireau T., Thomas B., Amouroux D., Berail S., Brach-Papa C.

Copper (Cu), mercury (Hg) and lead (Pb) are elements and contaminants of historical and emerging concerns in coastal environments. Although Cu is considered essential for living organisms, it is bioactive in a narrow range of optimal concentrations. Hg and Pb have no known biological role and are considered toxic towards organisms. Marine consumers incorporate and bioaccumulate these metals mainly through trophic pathways, which are then important to delineate.

[CEST2019_00328] Effect of oxygen functional groups on mercury retention in activated carbons
by Sotiropoulou R.E.P., Serafidou M., Skodras G.

Two commercial activated carbons (F400 and RWE) were tested for their Hg° retention capacity, in order to elucidate shortcomings that still exist, with respect to the oxygen functional groups. The number and the nature of oxygen containing functional groups were altered by heating under H2 at 1100°C or treatment with HNO3. The activated carbons tested were found suitable for mercury retention and the observed differences are attributed to their diversified characteristics (surface chemistry and pore structure).
