Lead and zinc as indicators for atmospheric and riverine particle-transport to sediments in the gulf of lions
Profiles of 0.1 N HCl leachable Pb and Zn in the sediments of the Gulf of Lions (North West Mediterranean) indicate that the concentrations of these metals are, especially in the vicinity of the triple-overdot Rhone outflow and in the Rhone plume, determined by input from the river. Solid phase Pb a...
