First Ecohydrology Seminar of 2022 held in-person

Today, we held our first in-person research seminar since the start of the pandemic. About 40 people gathered to hear Dr. Lewis Alcott present his seminar entitled “Phosphorus and climate through time and sampling uncertainties in the past and present”. Dr. Alcott is currently a Hutchinson Environmental Postdoctoral Fellow at Yale University working on the characterization and implications of the spatial and temporal variability of GHG sources. He holds a PhD degree from the University of Leeds.

Philippe presents at the 9th International Conference on Water Resources and Environment Research

This year’s theme of the 9th International Conference on Water Resources and Environment Research (ICWRER) is Bridging the Gaps of Interdisciplinary Sustainability for Complex Water and Environmental Systems. The Conference was held virtually on April25 to 27. Philippe gave an invited talk in the session on Eco-water Security and Smart Water Management in Large River Basins, chaired by Profs. Jun Xia and Gangsheng Wang. The topic of the talk was Biogeochemical Impacts of River Damming: Lessons Learned and Implications for Watershed Management.

New paper examines agricultural phosphorus surpluses in Ontario

A new paper reconstructs the agricultural phosphorus (P) inputs across the province of Ontario since the 1960s. The first author of the paper, entitled Agricultural phosphorus surplus trajectories for Ontario, Canada (1961-2916), and erosional export risk, is former ERG MSc student Tamara Van Staden. Co-authors include the ERG members Chris Parsons, Zahra Akbarzadeh, and Philippe Van Cappellen, as well as their colleagues Kim Van Meter and Nandita Basu.

New paper analyzes the effects of flavins and siderophores on the oxidation of ferrous iron by molecular oxygen

The oxidation of Fe(II) plays an important role in the biogeochemical cycling of redox-sensitive elements and the fate and transport of pollutants in subsurface environments. In a joint study by researchers from ERG and China University of Geosciences, the kinetics of aqueous Fe(II) oxidation by O2 were measured at variable pH in the presence of riboflavin and desferrioxamine B as representative flavins and siderophores, respectively. The study closes important gaps in our understanding of the reaction mechanisms involved.
