In partnership with the Inuit community of Kangiqsualujjuaq (Nunavik, Québec, Canada), our research investigates how climate-driven Arctic warming and northern greening can influence mercury (Hg) dynamics in snowpacks and surrounding ecosystems. We also collaborate on community-based environmental monitoring to better understand potential exposure pathways through country foods, including traditional food preparation, and to document the distribution and bioaccumulation of rare earth elements (REE) across local terrestrial, freshwater, and marine species in the context of emerging mining activities.
