DISTRIBUTION, SPECIATION, AND BIOAVAILABILITY OF LANTHANIDES IN THE RHINE-MEUSE ESTUARY, THE NETHERLANDS

摘要

Changing environmental conditions may influence the fate and bioavailability of lanthanides (part of the rare earth elements [Ln])in estuaries. The aim of this study was to quantify the variation of estuarine lanthanide solid/water distribution, speciation, and bioaccumulation. The latter was studied in the amphipod Corophium volutator under field laboratory conditions. Calculations with the chemical equilibrium model MINEQL+ indicate that dissolved lanthanides are complexed mainly to carbonates And dissolved organic matter.
