TL;DR: In this paper, the authors measured the dissolved, particulate, and (by cross-flow filtration) colloidal fractions of Cd, Ni, Zn, Cu, Pb, Mn, and Fe in the Gironde, an estuary in southwestern France.

TL;DR: A survey of Pb concentrations in surface seawater at 40 stations has revealed poor seawater quality, affecting both the dissolved fraction and suspended particles and points to marina/harbors as additional diffuse sources of dissolved Pb.

TL;DR: In this paper, the magnitude and the chronology of anthropogenic impregnation by Hg and other trace metals of environmental concern (V, Cr, Ni, Cu, Zn, Ag, Cd and Pb, including its stable isotopes) in the sediments are determined at the DYFAMED station, a site in the Ligurian Sea (Northwestern Mediterranean).

TL;DR: Temporal comparison of the data indicates some evidence of imposex recovery in most affected populations, and will serve as a reference for long-term monitoring of butyltin contamination in the Tunisian coast, where TBT restrictions were not yet implemented.

TL;DR: Investigation of variations of C and N elemental and isotopic ratios in common bivalves revealed shifts and trends for part of the 30-year series with decreases in δ13C and δ15N, likely linking bivalve isotopic ratio shifts to a cascade of processes affected by local drivers.
