The work of PhD student and Cluster trainee Kate Smith, a member of the Pacific Centre for Isotopic and Geochemical Research headed by Professor Dominique Weis, was featured in an online article.  The article summarizes Kate's work using honey to identify sources of industrial pollutants such as lead.  Ratios of particular lead isotopes found in honey from urban environments is vastly different to those from more rural sources, meaning that honey could be used as a biomarker for industrial pollution.  These findings were mirrored in salmon, where juvenile salmon, who breed and live in remote freshwater areas have lead isotope ratios that reflect the nascent environment, whereas mature salmon that forage in the open ocean have lead isotope levels similar to that of honey from urbanized sources.
