New paper presents model for representing the effects of freeze-thaw cycles on methanogenic hydrocarbon degradationNew paper presents model for representing the effects of freeze-thaw cycles on methanogenic hydrocarbon degradation

Cold regions are warming much faster than the global average, resulting in more frequent and intense freeze thaw cycles (FTCs) in soils. A new paper published in the journal Chemosphere investigated the effects of FTCs on toluene biodegradation using a combined experimental and model approach. The paper is authored by Mehdi Ramezanzadeh, a recent Masters graduate and current research assistant in the Ecohydrology Research Group.

New paper presents a reaction-transport model to simulate the multi-year fate and transport of phosphorus in a bioretention cell facility in the greater Toronto metropolitan area

A new paper in Science of the Total Environment presents a reaction-transport model to simulate the multi-year fate and transport of phosphorus (P) in a bioretention cell facility in the greater Toronto metropolitan area.  The paper is authored by Bowen Zhou, a PhD student in ERG. Co-authors from ERG include Mahyar Shafii, Chris T. Parsons, Elodie Passeport, Fereidoun Rezanezhad, Ariel Lisogorsky and Philippe Van Cappellen.

New paper examines the geo-environmental and land use controls on the distribution of selenium in organic-rich soils of cold regions

Selenium (Se) is an essential micronutrient but becomes toxic when people are exposed to excess levels. A new paper published in the journal Environmental Science and Technology presents a detailed analysis of the Se distribution in the cold region mollisol agroecosystems of northeastern China. The results indicate that the Se can be sourced back to chemical weathering of oil shales from the watershed source area and deposited along with organic matter during the fluvial deposition.

New paper explores inorganic carbon cycling in a reservoir within the largest karst area of the world in SW China

Wanfa Wang, a former ERG International Visiting Graduate Student from Tianjin University, published a new paper in the Journal of Hydrology describing his PhD research on carbon cycling in dam reservoirs in karst regions. Co-authors from ERG include Steph Slowinski, Shuhuan Li and Philippe Van Cappellen. Chemical and physical carbonate rock weathering in karst regions supply large quantities of particulate and dissolved inorganic carbon (PIC and DIC) to rivers and, ultimately, to the ocean.
