Environmental context Understanding mercury transformations in the aquatic environment is of utmost importance for the improvement of mercury biogeochemical modelling and sound environmental risk assessment. In such a context, we discuss critically t

Understanding of mercury (Hg) complexation with low molecular weight (LMW) bioligands will help elucidate its speciation. In natural waters, the rate of this complexation is governed by physicochemical, geochemical and biochemical parameters. However

In the comments reported by A. Manceau [1], relating to our recent paper on mercury (Hg) species-specific isotopic characterization in giant petrel tissues [2] two critical questions were raised. Firstly, according to A. Manceau, our method of extrac

En 2013, une étude de l'ANSES sur la contamination par le mercure (Hg) des poissons des quatre plus grands lacs aquitains (Hourtin-Carcans, Lacanau, Cazaux-Sanguinet et Parentis-Biscarrosse) a montré que les concentrations de mercure chez le sandre

Seabirds accumulate significant amounts of mercury (Hg) due to their long-life span together with their medium to high trophic position in marine food webs. Hg speciation and Hg isotopic analyses of total Hg in different tissues (pectoral muscles, li
