Additive and interactive cumulative effects on boreal landbirds; winners and...
Stressors created by multiple resource industries can result in cumulative effects over time and space. Many studies have evaluated single stressors and assumed that cumulative... -
Migrating Whooping Cranes avoid wind-energy infrastructure when selecting...
Abstract Electricity generation from renewable-energy sources has increased dramatically worldwide in recent decades. Risks associated with wind-energy infrastructure are not... -
Integrated analysis of petroleum biomarkers and polycyclic aromatic...
Abstract We examined polycyclic aromatic compounds (PACs) and petroleum biomarkers (steranes, hopanes, and terpanes) in radiometrically-dated lake sediment cores from the... -
Inter-annual variation of mercury in aquatic bird eggs and fish from a large...
Abstract: Understanding changes in environmental mercury concentrations is important for assessing the risk to human and wildlife populations from this potent toxicant. Here, we... -
Co-exposures to trace elements and polycyclic aromatic compounds (PACs)...
Highlights • Baculum bone health and liver contaminants were evaluated in river otter. • Protective and deleterious effects were detected for select contaminants. • Alkylated... -
Vanadium Stable Isotopes in Biota of Terrestrial and Aquatic Food Chains
Abstract Abstract Image Vanadium, a potentially toxic metal, is enriched in the environment from anthropogenic releases, particularly during fossil fuel production and use and... -
Non-target profiling of bitumen-influenced waters for the identification of...
The objective of this study was to identify unique chemical tracers of oil sands process-affected water (OSPW) to enable definitive discrimination of tailings pond seepage from... -
Potential Influence of Sewage Phosphorus and Wet and Dry Deposition Detected...
The health of fish is a primary indicator of ecosystem response in the Oil Sands Region of northeastern Alberta. However, industrial activity is accompanied by other stressors,... -
Preparative isolation, fractionation and chemical characterization of...
Abstract: Recent analytical advances have provided evidence that groundwater affected by oil sands process-affected water (OSPW) is reaching the Athabasca River at one location.... -
Improving Insights on Air Pollutant Mixtures and Their Origins by Enhancing...
An “event-based” approach to characterize complex air pollutant mixtures was applied in the Oil Sands region of northern Alberta, Canada. This approach was developed to better-... -
A decadal synthesis of atmospheric emissions, ambient air quality, and...
This article is part of the special series “A Decade of Research and Monitoring in the Oil Sands Region of Alberta, Canada.” The series documents the history of monitoring in... -
Quantifying fugitive gas emissions from an oil sands tailings pond with...
Abstract Fugitive emissions from tailings ponds contribute significantly to facility emissions in the Alberta oil sands, but details on chemical emission profiles and the... -
New methodology shows short atmospheric lifetimes of oxidized sulfur and...
Abstract The atmospheric lifetimes of pollutants determine their impacts on human health, ecosystems and climate, and yet, pollutant lifetimes due to dry deposition over large... -
Characterization and source apportionment of airborne particulate elements...
Highlights • 48 elements in PM2.5 and PM2.5–10 were analyzed at four air monitoring sites. • Elements contributed 8–11% and 16–28% of PM2.5 and PM2.5–10 mass respectively. •... -
