Relating the Speciation of Rare Earth Metals to their Bioavailability


Dr. Kevin Wilkinson from the University of Montreal, discusses relating the speciation of rare earth metals to their bioavailability. These metals are used in a variety of industries (electronics, hybrid cars, etc.) but also in high volume applications such as catalysts and agriculture. Dr. Wilkinson’s work shows that simple equilibrium models are not always appropriate for predicting metal uptake/toxicity and that speciation measurements such as DGT or simple extractions might be better alternatives for predicting biouptake of rare earth metals.
