Investigating arsenic bioavailability and bioaccumulation by the freshwater oligochaete Lumbriculus variegatus
The complex and variable composition of natural sediments makes it difficult to predict the bioavailability and bioaccumulation of sediment-bound contaminants. Several approaches, including an experimental model using artificial particles as analogues for natural sediments, have been proposed to ove...
