Particulate matter emissions over the oil sands regions in Alberta, Canada

Abstract

Particulate matter (PM) emissions from the expanded oil sands development in Alberta are becoming a focus among the aerosol science community because of its significant negative impact on the regional air quality and climate change. Open-pit mining, petroleum coke (petcoke) dust, and the transportation of oil sands and waste materials by heavy-duty trucks on unpaved roads could release PM into the air. Incomplete combustion of fossil fuels by engines and stationary boilers leads to the formation of carbonaceous aerosols. In addition, wildfire and biogenic emissions surrounding the oil sands regions also have the potential to contribute primary PM to the ambient air. Secondary organic aerosol formation has been revealed as an important source of PM over nearby and distant areas from the oil sands regions. This review summarizes the primary PM sources and some secondary aerosol formation mechanisms that are linked to oil sands development. It also reviews the approaches that can be applied in aerosol source apportionment. Meteorological condition is an important factor that may influence the primary PM emission and secondary aerosol formation in Alberta’s oil sands regions. Current concern should not be limited to the primary emission of atmospheric PM. Secondary formation of aerosols, especially secondary organic aerosol originating from photochemical reaction, should also be taken into consideration. To obtain a more comprehensive understanding of the sources and amount of PM emissions based on the bottom-up emission inventory approach, investigations on how to reduce the uncertainty in determination of real-world PM emission factors for the variable sources are needed. Long-range transport trajectories of fine PM from Alberta’s oil sands regions remain unknown.

“…But in providing the desired investment climate, the top priority that must be considered are government regulations. Some other instances of transdisciplinary researches: the treats of oil and gas project to the wilderness, biodiversity, and indigenous peoples in a certain area [14]; long-term gas extraction which induced earthquakes [15]; microbial communities associated with barley growing oil sands reclamation area [16]; negative impact of particulate matter emissions from the expanded oil sands development on the regional air quality and climate change [17]; the consequences of oil and gas development for the distribution of vegetation cover and for species persistence [18]; the impacts of oil and gas operation to the air near the projects that conduct horizontal drilling, hydraulic fracturing, and other drilling and well stimulation technologies which are now used widely in some countries [19]; and the effect of shallow natural gas well structures and associated roads on grassland song bird population declines due to habitat loss and degradation [20]. The aim of those researches are to identify legal instruments or structures realizing an ecosystem approach [21] in responsible experts and policymakers avoiding conflicting approaches to policy-making.…”

“…The CR notes that PACs originate from a variety of sources, including engine exhaust, stack emissions, wildfires, and fugitive dust from mine faces, tailings berms, and the large petcoke stockpiles. A growing number of studies indicate that fugitive dust, especially that from petcoke piles is a major source of miningrelated PACs found in emissions and the surrounding environment (Harner et al 2018;Jariyasopit et al 2018;Jautzy et al 2015;Landis et al 2019a;Manzano et al 2017;Xing and Du 2017;Zhang et al 2016). Few studies have investigated the effects of petcoke on OSR wildlife; one of which examined the potential for petcoke to limit the exposure of aquatic biota to the residual contaminants associated with fine tailings (Baker, Ciborowski, and MacKinnon 2012) and another which examined the potential toxic effects of petcoke extracts in birds (Crump et al 2017).…”
