Research interests
Responsible mining is an important societal and environmental issue for Canada, which has vast mineral and water resources. Professor Crémazy and her team aim at understanding the processes that govern the interactions between metals and aquatic organisms. Of particular interest is the study of bioavailability of metals in natural waters. This research programme is divided into three main areas:
- Characterization of the geochemistry of metals in natural waters
- Characterization of the influence of environmental and biological variables on the bioavailability of metals
- Exploration of the biological fate of metals
This research work takes place in the laboratory and in the field, and covers a wide range of aquatic organisms (phytoplankton, gastropods, fish), environments (rivers, lakes, coastal areas), and regions (temperate, tropical and polar), and relies on techniques and concepts from analytical chemistry, biogeochemistry, biochemistry, toxicology, physiology, and ecology.
The techniques, data, and knowledge obtained are used to support better management of the environmental risk of metals in natural waters.
