Oceanic cadmium cycle driver found

Using innovative metal-isotope analysis of components from within the cell, department scientists have demonstrated that the nutrient-like behaviour of cadmium in seawater is caused by marine species removing this toxic metal from their cells.  This result solves a long-standing puzzle in ocean chemistry. 

The work, led by graduate student Tristan Horner, was published on 29th January in the Proceedings of the National Academy of Science.
