Isotopic Analyses Fingerprint Sources of Polycyclic Aromatic Compound-Bearing Dust in Athabasca Oil Sands Region Snowpack

Autor: Colin A. Cooke, Jason M. E. Ahad, Martine M. Savard, Paul Gammon, Hooshang Pakdel, Thibault Labarre

Publikováno v: Environmental sciencetechnology. 55(9)

Fugitive dust associated with surface mining activities is one of the principal vectors for transport of airborne contaminants in Canada’s Athabasca oil sands region (AOSR). Effective environmental management requires quantitative identification of

Heated column experiments: A proxy for investigating the effects of in situ thermal recovery operations on groundwater geochemistry

Autor: Richard T. Amos, Paul Gammon, Andrew T. Craig

Publikováno v: Journal of contaminant hydrology. 237

In situ thermal recovery is utilized extensively for unconventional bitumen extraction in the Cold Lake-Beaver River (CLBR) basin in Alberta, Canada. Public health concerns have been raised over potable groundwater contamination and arsenic release a

Applied Geochemistry, Elsevier, 2018, 90, pp.50-62. ⟨10.1016/j.apgeochem.2017.12.026⟩

Oil sands operations in Alberta, Canada generate large volumes (>840 × 106 m3) of oil sands process-affected water (OSPW) that contains contaminants that are toxic to aquatic life. OSPW is stored in open tailings ponds and leakage from the ponds pre

Puzzling Zn isotopes in spruce tree-ring series

Autor: J.E. Vaive, Christian Bégin, Martine M. Savard, Isabelle Girard, Paul Gammon, Lauriane Dinis

Publikováno v: Chemical Geology. 476:171-179

Zinc (Zn) isotopes have shown promise for investigating biogeochemical processes and tracing sources of Zn for environmental studies. This study, the first in its kind, investigates Zn isotopic ratios in tree rings and soils of two sites in the North

Iron and magnesium isotope geochemistry in hydrothermal uranium ore systems: Insights from the Bong Deposit, Canada

Autor: Isabelle Girard, Paul Gammon, Ryan Sharpe, Eric G. Potter, Mostafa Fayek

Publikováno v: Journal of Geochemical Exploration. 229:106843

The basement-hosted Bong uranium deposit in the Kiggavik region is associated with a broad hydrothermal alteration halo characterized by an inner illite-rich zone and an outer chlorite-rich zone. The uranium-bearing zones characterized by intense ill

Influence of climatic conditions and industrial emissions on spruce tree-ring Pb isotopes analyzed at ppb concentrations in the Athabasca oil sands region

Autor: Paul Gammon, Martine M. Savard, Christian Bégin, J.E. Vaive, Lauriane Dinis

Publikováno v: Dendrochronologia. 37:96-106

This study investigates Pb isotope ratios at low concentrations (parts per billion; ppb) in tree rings and soils in the Northern Athabasca Oil Sands Region (NAOSR), western Canada, to evaluate if: (1) climatic conditions influence on tree-ring Pb ass
