Autor: John Chételat, Sune G. Nielsen, Maureen E. Auro, Philippe J. Thomas, David O. Carpenter, Lukas J. Mundy

Publikováno v: Environmental Science & Technology. 55:4813-4821

Vanadium, a potentially toxic metal, is enriched in the environment from anthropogenic releases, particularly during fossil fuel production and use and steel manufacturing. Metal stable isotopes are sophisticated tools to trace pollution; however, on

Publikováno v: Environmental Science & Technology. 53:9192-9202

Recent contaminant monitoring in boreal wetlands situated in Alberta's Athabasca oil sands region revealed increased concentrations of polycyclic aromatic compounds (PACs) in passive sampling devices deployed in wetlands close to bitumen surface mini

Transformation of bitumen-derived naphthenic acid fraction compounds across surface waters of wetlands in the Athabasca Oil Sands region

Bitumen is extracted from oil sands in the Athabasca Oil Sands region (AOSR) of Alberta, Canada. Much of the bitumen-derived toxicity in mine waste is attributable to naphthenic acid fraction compounds (NAFCs). Mines in the AOSR are required to be re

Publikováno v: Environmental pollution (Barking, Essex : 1987). 270

We examined polycyclic aromatic compounds (PACs) and petroleum biomarkers (steranes, hopanes, and terpanes) in radiometrically-dated lake sediment cores from the Athabasca oil sands region (AOSR) and the Peace-Athabasca Delta (PAD) region in Alberta

Characterization of naphthenic acid fraction compounds in water from Athabasca oil sands wetlands by Orbitrap high-resolution mass spectrometry

Publikováno v: Science of The Total Environment. 780:146342

Classical naphthenic acids (NAs) are known to be primary aquatic toxicants of concern in the Athabasca oil sands region (AOSR), and are a component of naphthenic acid fraction compounds (NAFCs). Recent studies conducted in the AOSR have examined meta

Spatial modelling of non-target exposure to anticoagulant rodenticides can inform mitigation options in two boreal predators inhabiting areas with intensive oil and gas development

Autor: Philippe J. Thomas, Lukas J. Mundy, Kristin M. Eccles

Publikováno v: Biological Conservation. 212:111-119

Intensive industrial development occurs in the ecologically significant boreal forest, including oil and gas development in northern Alberta, Canada. This forest is home to many highly-valued animal species including fisher ( Pekania pennanti ; forme

Using wood frog (Lithobates sylvaticus) tadpoles and semipermeable membrane devices to monitor polycyclic aromatic compounds in boreal wetlands in the oil sands region of northern Alberta, Canada

Publikováno v: Chemosphere. 214

Several recent studies have reported evidence that surface mining operations of bitumen in northern Alberta's oil sands (OS) region contribute significantly to the atmospheric deposition of metals and polycyclic aromatic compounds (PACs) within the v

Publikováno v: Toxicology and Applied Pharmacology. 248:185-193

Some uncertainty exists regarding the purity of hexachlorobenzene (HCB) used in past toxicity studies. It has been suggested that reported toxic and biochemical effects initially attributed to HCB exposure may have actually been elicited by contamina
