But he doesn't know where it is coming from or how, when or where these marine mammals absorb it. He might soon be closer to the answers. answers. Trent has recently purchased a new inductively coupled plasma mass spectrometer and the manufacturer, manufacturer, Perkin-Elmer-Sciex, has donated donated two accessories that will make this possible: a laser sampler and a flow injection system. Evans knows there is cadmium in Arctic marine mammals because he has been able to analyse the chemistry chemistry of their teeth. Up to now, teeth have had to be liquified before they could be analysed. The new mass spectrometer with the laser sampler can analyse solids by extracting minute quantities and turning them into gas. ,Instead of reducing reducing an entire tooth to a single liquid, liquid, Evans will be able to keep the tooth intact and analyse each layer of growth separately. He will be able to tell at what age a seal ingested cadi- mum, and how much. The answers could hold the secret to the mystery source of this toxic metal, says the environmental studies professor. The $500,000 research tool can also determine the concentrations of many elements simultaneously, measure parts per trillion and measure measure the isotopes of elements. This means, for instance, that it will be able to determine whether lead found in ducks comes from ammunition or industrial sources, says Evans. This state-of-the-art equipment "opens a whole variety of new questions questions to us," says Evans, who is chair of the Watershed Ecosystems Graduate Graduate Program. "We'll be capable of undertaking projects and testing questions we wouldn't have dreamed of before." Trent received $325,000 from the Natural Sciences and Engineering Research Council for the spectrometer. spectrometer. Pcrkin-Elmer-Sciex donated the accessories, worth about $175,000, in exchange for working with the company company to hone the cutting-cdgc equipment. equipment.
