Scientists have combined analyses from honey and salmon to show how lead from natural and industrial sources gets distributed throughout the environment. By analysing the relative presence of differing lead isotopes in honey and Pacific salmon, Vancouver-based scientists have been able to trace the sources of lead (and other metals) throughout the region. Scientists in France, Belgium and Italy are now looking to apply the same approach to measure pollutants in honey in major European cities. The research is being presented at the Goldschmidt conference in Barcelona.
