Metals have many roles in biology. Some, like copper and iron, are needed at trace levels for health. Others, such as mercury and lead have no known positive role but instead can behave as poisons. Many metals have dual roles. The metals chemical form or speciation is key to its role, whether toxic or beneficial, but is challenging to determine in biological tissues. This program will use and develop techniques available at the Canadian Light Source, located at the University of Saskatchewan, to investigate the speciation and microscopic distribution of metals, with impacts in the environment and human health.

金属在生物学中有许多作用。有些，如铜和铁，是健康所需的微量元素。其他的，如汞和铅没有已知的积极作用，而是可以作为毒药。许多金属具有双重作用。金属的化学形式或形态是其作用的关键，无论是有毒还是有益的，但在生物组织中确定具有挑战性。该方案将使用和开发位于萨斯喀彻温大学的加拿大光源提供的技术，以调查金属的形态和微观分布，以及对环境和人类健康的影响。
