| Abstract: | Using X-ray Energy Spectroscopy trace metal concentrations (Ti, V, Mn, Fe, Ni, Cu, Zn, As, Pb) were measured in specimens of Eudistylia vancouveri (feather duster tube worms) collected from floating wharves near and far from a storm water outfall in a metropolitan area. As for the well-studied bio-accumulator Mytilus edulis (mussels), higher metal concentrations were noted in specimens near the pollution source. In particular the worms accumulated certain metals, namely vanadium and titanium, not picked up by the mussels, signaling that a new sentinel organism could be available. |
