La région de Rouyn-Noranda est fortement touchée par la contamination en éléments traces (ET), tels que l’arsenic (As), le cadmium (Cd), le cuivre (Cu) et le plomb (Pb), provenant des dépositions atmosphériques générées par les émissions

Chemical weathering of volcanic rocks in warm and humid climates contributes disproportionately to global solute fluxes. Geochemical signatures of solutes and solids formed during this process can help quantify and reconstruct weathering intensity in

The flow of energy and elements between the geosphere and biosphere can be traced through changing redox chemistry of Earth’s surface. Deep-time trends in the mineral record, including mineral age and elemental composition, reveal a dynamic history

Coccolithophores and other haptophyte algae acquire the carbon required for metabolic processes from the water in which they live. Whether carbon is actively moved across the cell membrane via a carbon concentrating mechanism, or passively through di

Ferruginous sediments were widespread during the Archaean and Proterozoic Eons, but our knowledge about organic matter mineralization remains mostly conceptual, as analogous modern ferruginous sediments are largely unstudied. In sediments of ferrugin

Alarming increases in tree mortality due to environmental change suggest that contributions of dead wood to global carbon (C) cycles are rapidly increasing 1-3, with dead wood C flux estimates already approximating total annual anthropogenic C emissi

Estuarine sediments are important sites for the interception, processing and retention of organic matter, prior to its export to the coastal oceans. Stimulated microbial co-metabolism (priming) potentially increases export of refractory organic matte

Stromatolites have been a major focus in the search for ancient microbial biosignatures, however, the organic carbon biosignatures of dolomitized stromatolites have not yet been fully characterized and correlated with their dolomitizing conditions. T

Sediment microbial communities are an important sink for both organic and inorganic nitrogen (N), with microphytobenthos (MPB) biomass having the largest contribution to short-term N-assimilation and retention. Coastal waters are increasingly subject

The Minamata Convention is a legally-binding international treaty aimed at reducing the anthropogenic release of mercury, a potent neurotoxin. However, its human health benefit has not been quantified on a global scale. Here we evaluate the Conventio
