Resumo: 	Concentrations of volatile hydrogen sulfide (H2S), carbonyl sulfide (OCS), methane thiol (MeSH), dimethyl sulfide (DMS), and dimethyl disulfide (DMDS) in the Seine estuary (France) were investigated in spring 2005 using samples collected from the first meter beneath the surface. Levels of dissolved metals (Ag, Cd, Cu, Zn, Ni, Co, Pb), suspended particulate matter, and particular organic carbon were also assessed. Maximum concentrations were 0.80 nM for H2S, 0.64 nM for OCS, 3.06 nM for MeSH, 11.06 nM for DMS, and 1.18 nM for DMDS, and different features were observed for the five volatile reduced sulfur compounds (VRSCs). Experiments were conducted to determine silver-VRSC conditional stability constants. Major interactions were observed between H2S and Ag, which may partially account for the absence of volatile H2S at the lowest salinities. OCS, MeSH, and DMS did not interact with Ag, as revealed by their insignificant K' values. Variations in concentrations along the salinity gradient may be explained by the influence of phytoplanktonic compounds.
