Oil Sands Environmental Management Bibliography

The Cumulative Environmental Management Association (CEMA)partnered with the Oil Sands Research and Information Network (OSRIN) to create the new Oil Sands Environmental Management Bibliography, which includes documents relevant to the environmental management of oil sands development in Alberta. The majority of the documents focus on the mineable oil sands in the Athabasca deposit, though some documents relate to in-situ developments. This bibliography was last updated in November 2014.

The acute and sub-chronic exposures of goldfish to naphthenic acids induce different host defense responses

Year of Publication: 2012

Abstract:
Naphthenic acids (NAs) are believed to be the major toxic component in oil sands process-affected water (OSPW) produced by the oil sands mining industry in Northern Alberta, Canada. We recently reported that oral exposure to NAs alters mammalian immune responses, but the effect of OSPW or NAs on the immune mechanisms of aquatic organisms has not been fully elucidated. We analyzed the effects of acute and sub-chronic NAs exposures on goldfish immune responses by measuring the expression of three pro-inflammatory cytokine genes, antimicrobial functions of macrophages, and host defense after challenge with a protozoan pathogen (Trypanosoma carassii). One week after NAs exposure, fish exhibited increased expression of pro-inflammatory cytokines (IFNγ, IL-1β1, TNF-α2) in the gills, kidney and spleen. Primary macrophages from fish exposed to NAs for one week, exhibited increased production of nitric oxide and reactive oxygen intermediates. Goldfish exposed for one week to 20 mg/L NAs were more resistant to infection by T. carassii. In contrast, sub-chronic exposure of goldfish (12 weeks) to NAs resulted in decreased expression of pro-inflammatory cytokines in the gills, kidney and spleen. The sub-chronic exposure to NAs reduced the ability of goldfish to control the T. carassii infection, exemplified by a drastic increase in fish mortality and increased blood parasite loads. This is the first report analyzing the effects of OSPW contaminants on the immune system of aquatic vertebrates. We believe that the bioassays depicted in this work will be valuable tools for analyzing the efficacy of OSPW remediation techniques and assessment of diverse environmental pollutants.

The acute toxicity of saline groundwater and of vanadium to fish and aquatic invertebrates

Year of Publication: 1979

Abstract:
In order to conduct oil sands mining operations in the surface mining region of the Athabasca oil sands deposits, most regions require depressurization of the basal sandstone formations. The groundwater produced by depressurization operations is of poor enough quality to be toxic to fish. The purpose of this project was to provide detailed information regarding the acute toxicity this mine depressurization water to both fish and invertebrates. This project was initiated in early 1976 with a general goal \"to provide a sequence of toxicity testing applicable to use for on-site studies and to provide a basis for future evaluations of species for experimentation\". Other parallel toxicological investigations conducted by AOSERP since then include \"Acute and Chronic Toxicity of Vanadium to Fish\" (AOSERP Report 41) and \"Acute Lethality of Mine Depressurization Water to Trout-Perch and Rainbow Trout Volume I.” (AOSERP Report 23).

The adsorption and release of sulfur in mineral and organic soils of the Athabasca oil sands region, Alberta, Canada

Year of Publication: 2010

Abstract:
Mineral soil and fibric peat from acid-sensitive western boreal catchments in the Athabasca Oil Sands Region of Alberta, Canada were evaluated for their ability to adsorb and release SO4 2− Laboratory batch studies indicated that SO4 2− adsorption in mineral soil from both the A and B horizons exhibits a limited response to elevated SO4 2− concentrations, with the slope of initial mass isotherms <0.2 for all soils, likely due to low iron and aluminum oxide content. Although S retention is the dominant process in peat soils in the region, drought simulations in the lab using fibric peat collected from a poor fen exhibited as much as a five-fold increase in SO4 2− concentration after drying and rewetting. Given the limited SO4 2− adsorption capacity of mineral soils and the potential drought-induced S release from peatlands in this region where increased S deposition is expected, further investigation of acidification impacts is warranted.

The Alberta oil sands and climate

Year of Publication: 2012

Abstract:
Developing the Alberta oil-sands will lead to carbon emissions that in turn result in global warming. Our paper calculates the amount of warming the oil-sands could potentially cause. We also consider how oil-sands carbon emissions relate to the effort to keep global mean temperatures from exceeding 2°C above pre-industrial levels, as agreed to in the Copenhagen Accord. Finally, we compare the potential for warming of the Alberta oil-sands with the potential for warming of other global fossil-fuel resources.

The Alberta Oil Sands Community Exposure and Health Effects Assessment Program: Methods report

Authors
Year of Publication: 2000

Abstract:
The Alberta Oil Sands Community Exposure and Health Effects Assessment Program was modeled after the USEPA TEAM approach. The TEAM approach is based on four fundamental characteristics: direct measurement of all routes of exposure (breathing, ingestion, and skin contact), direct measurement of biomarkers, daily logs of a participant’s activities, and a representative probability sample. The study was designed to assess exposure and associated health effects by direct measurement of personal exposure, direct measurement of biomarkers, and daily logs of a participant's activities. The contaminants identified for personal exposure measurement for the Alberta Oil Sands Community Exposure and Health Effects Assessment Program were sulphur dioxide, nitrogen dioxide, ozone, volatile organic compounds, and particulates. The biological measures of effect included in the study included: autoantibody activity, a neurocognitive assessment, and a respiratory health assessment including a respiratory health history survey and a spirometry assessment. In addition to the direct measures of exposure and the measurement of biological markers of exposure and effect, the study instruments also included a time-activity diary that required participants to record daily activities that might have an effect on exposure.

The Alberta Oil Sands Community Exposure and Health Effects Assessment Program: Summary report

Authors
Year of Publication: 2000

Abstract:
This report provides an overview of the Alberta Oil Sands Community Exposure and Health Effects Assessment Program Main Study. The report describes the population and personal distribution of exposure to airborne chemicals and particulates in the city of Fort McMurray. Using a personal exposure model, the relative contribution of various exposure sources and pathways to airborne chemicals is estimated and associations between exposure to airborne chemicals and human health effects are described. The data used for the analysis was collected over an 18-month period (June 1997 to November 1998), using volunteers from the city of Fort McMurray. A small sample of volunteers was also recruited from the city of Lethbridge that served as a control community for the Fort McMurray sample. Data from the two communities was evaluated and, where applicable, additional comparisons were made to the scientific literature. The study collected a variety of measures for each participant, including personal, indoor, and outdoor levels of selected contaminants (sulfur dioxide, nitrogen dioxide, ozone, a group of volatile organic compounds, and particulate matter), measures of other sources of exposure, diet and health behaviors, and selected health outcomes.

The Alberta oil sands journalists and their sources

Authors Paskey, J., & Steward G.
Year of Publication: 2012

Abstract:
Twenty journalists who regularly produce articles, televised reports and videos about the Alberta oil sands and issues pertaining to the oil sands participated in this study. Although most of the stories about the Alberta oil sands that appear in the news media have a business or economic focus, this study reveals that a clear majority of the 20 journalists who participated believe that the tension between economic and environmental aspects of oil sands development is the driving issue. A clear majority of respondents also said that there are many stories about the oil sands that go unreported and many of these unreported stories have to do with environmental issues. While journalists didn’t specify why certain stories are not covered by the news media, they did report that some of the sources they would need to produce credible articles or documentaries are not easily available and, in some cases, not available at all. Most reported that industry sources are easily available although they would prefer to speak with decision makers rather than communications staff. And while they often rely on government statistics about the oil sands and the environment, a significant number of respondents said it is usually difficult to reach federal and provincial government representatives to discuss these statistics. Academics have become an important source of expertise, particularly for journalists who write about environmental issues, as have advocacy groups such as the Pembina Institute. However, most journalists suggested that there are so many vested interests with a stake in oil sands development that it is often difficult to know who to believe. For this reason they use a variety of sources, especially when covering environmental issues. Most journalists suggested that up-to-date expertise is such a valuable commodity when reporting about the oil sands that they expect all their sources to have it, even citizen and Aboriginal sources. It is also apparent that most of the journalists rely heavily on online sources of information such as other media stories, government reports and documents, industry updates, advocacy group reports and events, contact information for Aboriginal bands, statistical information of all sorts, and media releases. Most of the respondents were experienced journalists who have been covering the Alberta oil sands for more than five years. They believe that oil sands development is one of the most important, if not the most important issue, facing the province and the rest of the country.

The Alberta oil sands then and now: An investigation of the economic environmental and social discourses across four decades

Year of Publication: 2013

Abstract:
A detailed study of dozens of documents pertaining to the Alberta oil sands produced by the Alberta government over the past 40 years shows the government’s perspective regarding this vast resource has undergone a major shift. In the 1970s and early 1980s, the Alberta government initiated detailed studies and scientific investigations to better determine oil sands policy. By the mid-1990s documents suggest the government had abandoned that role in favour of promotion and marketing of the oil sands. It is quite clear from government documents produced in the 1970s that most of the economic, environmental, and social impacts associated with rapid expansion of oil sands operations (often referred to as tar sands in the 1970s) were anticipated. Various studies and surveys were also undertaken by the government of the day to determine how to avoid these negative impacts. For example, a 1973 Alberta Environment report – An Environmental Study of the Athabasca Tar Sands – states: “The disposal of tailings from the hot water extraction process represents the most imminent environmental constraint to the future expansion of this recovery method.” Documents reviewed suggest that at the time the Alberta government saw itself as being primarily responsible for further development of the oil sands. To this end, the government invested millions of dollars in the Alberta Oil Sands Technology and Research Authority (AOSTRA) to kick start expansion. AOSTRA initiated and funded research into technological innovation for the extraction of bitumen. Another government agency – Alberta Oil Sands Environmental Research Program (AOSERP) – investigated social conditions for people living near oil sands plants and environmental impacts such as air emissions and tailings ponds. By the mid-1980s the Alberta government had pulled back from this direct kind of involvement with oil sands development. And even though much research into environmental and social impacts had been carried out it was put on the back burner in favour of more immediate economic benefits. This study also examined documents pertaining to the oil sands produced by industry, academia, non-governmental organizations, and the news media over the past 40 years during which time oil sands operations expanded from two to seven oil sands mining projects, 26 commercial in situ projects approved, in addition to about 130 primary recovery projects and 12 experimental schemes. The study revealed that public discourse about the oil sands has shifted from one that was primarily focused on the economic benefits of oil sands development to a conversation that involves a multiplicity of issues and voices. Economic signifiers such as job creation, royalty revenues, foreign investment, and markets are still key when it comes to talking about the oil sands. But in the last 10 to 15 years, global issues such as climate change, indigenous rights, pollution of the air and major waterways, and sustainability have become embedded in the discourse about the oil sands. Nowadays, the oil sands are talked about as if they are an arena in which key players and issues vie for attention. The entry of other voices into the discourse about the oil sands has also affected Canada’s dialogue with the United States regarding oil exports. Whereas the United States was once discussed as the prime customer that must be satisfied at all costs, now governments and industry talk about the U.S. as a riskier market and seek to export the oil to China, India and other emerging markets as well. There are some significant language choices that stand out in the media, particularly the distinction between “tar sands” and “oil sands.” It has been suggested in media coverage that supporters for the development of this resource use the label “oil sands”, whereas critics deploy “tar sands”. While this claim rings true, in the media sample reviewed it becomes evident that “tar sands” was used during the 1980s and 1990s in a completely neutral way, simply in reference to the “Athabasca Tar Sands.” “Tar sands” became a more negative term only when it is associated with vivid descriptors such as being a “monster” that “needs to be fed”, or as the “black stain of Canada”, or simply talked about as something “dirty”, “sticky”, “gooey”, or “oozing.” These types of expressions are most often used by Aboriginal sources, environmentalists, political figures (members of the opposition), and sometimes journalists themselves. These stakeholders deploy such terms when they want to criticize the development of this resource. In the sample of articles examined, it was not until 2008 when the environmental action group Environmental Defence published Canada's Toxic Tar Sands: The Most Destructive Project On Earth that these types of negative add-ons started to appear. All of the documents examined in the study were in English, as were the news articles. This is an admitted limitation as we do not capture dialogue in francophone Canada. Most of the documents collected and analyzed for this report came from a database established by the Cumulative Environmental Management Association (CEMA), a collaborative organization based in Fort McMurray, Alberta that includes representatives from government, industry, academia, First Nations, civic and community organizations, and environmental groups. Other documents were collected from university, government, industry and NGO libraries and databases. The news articles were collected from two databases – CBCA Complete and Canadian Newsstand. Discourse about the oil sands is one of the most important conversations occurring in Canada and abroad. The deeper we can delve into that conversation, the more we can come to understand all the complexities, risks, and rewards that this vast resource presents to Albertans, Canadians and the world.

The analysis of goldfish (Carassius auratus L.) innate immune responses after acute and subchronic exposures to oil sands process-affected water

Year of Publication: 2014

Abstract:
We examined the immunotoxic effects of acute and subchronic exposures of goldfish to aged, fresh, and ozonated oil sands process-affected water (OSPW) using a flow-through exposure apparatus. We measured the expression of proinflammatory cytokine genes, the antimicrobial responses of primary macrophages isolated from OSPW-exposed fish, and the ability of the goldfish to control infection with a protozoan parasite, Trypanosoma carassii. After acute (1 week) exposure to aged OSPW, we observed upregulation in the expression of interferon gamma (IFN-γ), tumor necrosis factor alpha-2 (TNF-α2) in the kidney and spleen but not in gills of the fish. After subchronic (12 weeks) exposure to aged OSPW, we observed significant increases in mRNA levels of proinflammatory genes in the gill (IFN-γ, interleukin-1 beta 1 [IL1-β1], TNF-α2), kidney (IL1-β1, TNF-α2), and spleen (IL1-β1). An upregulation of immune gene expression in the gill and kidney (IFN-γ, IL1-β1, TNF-α2) and spleen (IL1-β1, TNF-α2) was observed after acute exposure of fish to diluted fresh OSPW. Following subchronic exposure to diluted fresh OSPW, we observed high mRNA levels of IL1-β1 in all tissues examined. However, there were significant decreases in the mRNA levels of IFN-γ and TNF-α2 in the kidney and spleen and gill and spleen (IL-12p35 and IL-12p40) of exposed fish. There were no changes in the expression of anti-inflammatory cytokine IL-10 after both acute and subchronic exposures to diluted fresh OSPW. In fish exposed to ozonated fresh OSPW, immune gene expression was similar to nonexposed control fish in all organs examined, with exception of IL1-β1. The ability of primary kidney macrophages to generate reactive oxygen and nitrogen intermediates was significantly reduced in fish exposed to fresh OSPW. The enhanced proinflammatory response after acute exposure to diluted fresh OSPW was confirmed by the parasite challenge experiments, where OSPW-exposed fish controlled the infection better than nonexposed fish.

The answer is still no: Voices of pipeline resistance

Year of Publication: 2014

Abstract:
The Answer Is Still No is an important, urgent book that compiles interviews with people who live along the route of the proposed Enbridge pipeline in Northern British Columbia. The oil pipeline and supertankers – linking the tar sands of Alberta to the demand of the growing Asian market – are a key component of Canada’s strategy of natural resource extraction. But for the people living along the proposed pipeline route, Enbridge poses a massive environmental risk, which threatens their way of life. This edited collection takes the passionate words and voices of twelve citizens and activists and results in one powerful position when it comes to blind economic development at the expense of our environment and communities: The answer is still “no.”

The application of algae for the removal of metals and naphthenic acids from oil sands tailings pond water

Authors Mahdavi, H.
Year of Publication: 2014

Abstract:
Bitumen recovery produces a large volume of TPW, which must be reclaimed using an efficient and cost-effective method. In this thesis, the ability of algae for in situ treatment of TPW, with a focus on metal and total acid-extractable organics (TAOs) removal, was assessed. An indigenous alga, found in cyclone overflow water, was capable of removing metals 53Cr, Mn, Co, 60Ni, 65Cu, 66Zn, As, 88Sr, 95Mo and Ba. Through the amplification of the 23S rRNA gene, the indigenous alga was identified as Parachlorella kessleri. Highest metal removal was achieved with the highest nutrient supplements (1.98 mM NO3- and 0.20 mM PO43-) in Syncrude TPW, and the lowest nutrient supplements (0.24 mM NO3- and 0.016 mM PO43-) in Albian TPW. This implies that higher concentrations of nutrient supplements do not necessarily improve the metal removal efficiency. FT-IR spectra revealed the presence of amide I, amide II bands, and carboxylic functional groups on the surface of P. kessleri; these sites likely contribute to metal removal. However, an acid-base titration showed that the carboxylic group was the only active proton binding site for metal binding. Intracellular bioaccumulation was the dominant mechanism of metal removal, with extracellular bioaccumulation and precipitation playing a smaller role. For the biodegradation of TAOs, a consortium of indigenous algae-bacteria was employed. Bacteria demonstrated the greatest removal of TAOs with a half-life removal rate of 203 days (first-order kinetics). The TAO removal rate did not correlate with detoxification of TPW, where most toxicity reduction was observed in samples containing the algae-bacteria consortium. Principal component analysis (PCA) was conducted on the FT-IR spectra. The significant loading wavenumbers, which likely indicated bio-transformed functional groups and bonds in the TAO molecules, were identified as: hydroxyl, carbocyclic and amid groups along with C-H, aryl-H, aryl-OH and N-H bonds. The observations from this research indicate that indigenous algae play an important role in the removal of metals and TAOs from oil sands TPW. However, for future engineering application, more investigates are required to optimize the operating conditions to improve the removal efficiency.

The application of remote sensing to environmental monitoring of the AOSERP study area. Volume 1.

Year of Publication: 1978

Abstract:
The purpose of this study was to examine the application of remote sensing to environmental monitoring of the Athabasca Oil Sands region and to demonstrate the way in which field-acquired and remotely-sensed data could be integrated. Vegetation field data were acquired and sample plots were subjectively divided into community and class groupings. False color infrared and true color aerial photography were examined. It was concluded that false color infrared aerial photography acquired during the period of maximum foliage development is most valuable for vegetation mapping and the detection of environmental disturbance. Thermal infrared night time imagery was found to be most valuable in the detection of thermal anomalies related to water features, and in the analysis of oil sands plant sites. LANDSAT color composite transparencies were studied and found to be valuable in providing an overview of the major ecological communities in the area, and of the progress of land clearing operations. Digital analysis of two summer images was done using the Image-IOO system at the Canada Centre for Remote Sensing in Ottawa. Change detection analysis of open water, cleared land, and disturbance vegetation appeared to be the most valuable application of LANDSAT digital data to environmental monitoring of the region. In an operational environmental monitoring program, remotely sensed data should be acquired at regular intervals. It is suggested that imagery acquisition for different areas within the Oil Sands region be specifically tailored to the current and expected activity in each area.
