The Effects of Winter Pulsed Warming and Snowmelt on Nitrogen Cycling in Agricultural Soils: A Lysimeter Study
Green, Danielle; Rezanezhad, Fereidoun; Jordan, Sean; Wagner-Riddle, Claudia; Henry, Hugh; Slowinski, Stephanie; Van Cappellen, Philippe (University of Waterloo, 2023-05-15)In cold regions, climate change is expected to result in warmer winter temperatures and increased temperature variability. Coupled with changing precipitation regimes, these changes can decrease soil insulation by reducing ... -
Enzymatic degradation of PET plastic
Griffiths, Erin; Slowinski, Stephanie; Honek, John; Van Cappellen, Philippe; Rezanezhad, Fereidoun (University of Waterloo, 2024-02-02)Previous work has shown that the degradation of plastics such as polyethylene terephthalate (PET) using commercial grade enzymes is possible and highly effective in lab settings. However, the environmental factors controlling ... -

Yu, Shengde; Radosavljevic, Jovana; Van Cappellen, Philippe (University of Waterloo, 2023-05-15)With increasing of population and socioeconomic development during the last decades, global constructions of dams and reservoirs have surged in diverse applications, such as flood control, and hydropower generation etc. ... -
Investigating drivers of microplastic pollution in urban settings
Reshadi, Mir Amir Mohammad; Rezanezhad, Fereidoun; Nguyen, Thu Hang; Slowinski, Stephanie; Kaykhosravi, Sarah; Van Cappellen, Philippe (University of Waterloo, 2023-05-30)As one of the emerging contaminants and the major by-products of plastic materials, microplastics (MPs) have recently been stated as being remarkable contaminants of different environmental matrices including soils, ... -
Landfill cover soils: variable moisture and temperature effects on methane oxidation
Lam, Christina; Slowinski, Stephanie; Willms, N; Hug, L; Van Cappellen, Philippe; Rezanezhad, Fereidoun (University of Waterloo, 2023-05-15)Landfills are one of the largest anthropogenic sources of methane (CH4), comprising over 20% of Canada’s CH4 emissions. Hot-spots of CH4 emissions in landfill cover soils have shown an enrichment of microbes that consume ... -
