Research summary
Metals are a critical part of the technologies that are powering the ongoing energy transition. But in high concentrations, they can pose risks to ecosystems and human health. Understanding how metals move through the Earth system is key to managing both their use and their environmental impact. Dr. Julie Prytulak, Canada Research Chair in Isotope Geochemistry, is investigating metal cycling at both deep-Earth and surface levels—from the formation of metal-rich deposits to the movement of metals through water, soil and sediments.
Using cutting-edge mass spectrometry, she and her research team are tracing metal sources and pathways through their isotopic signatures (the relative proportions of certain isotopes in a sample). They are also advancing new techniques that require far smaller samples than ever before, enabling more precise and sustainable analysis. Their findings will help identify critical metal resources, improve environmental monitoring, and support the safe, responsible use of metals.
