Federal

The health of individual amphibians, amphibian populations, and their wetland habitats are monitored in the oil sands region and at reference locations. Contaminants assessments are done at all sites. Amphibians developing near oil sands activities may be exposed to concentrations of oil sands-related contaminants, through air emissions as well as water contamination. The focus of field investigations is to evaluate the health of wild amphibian populations at varying distances from oil sands operations.

Tree swallow (Tachycineta bicolor) nest boxes are installed in oil sands area and in reference locations to monitor contaminant levels and impacts on tree swallow nestlings. The exposure to tree swallow nestlings to air-borne oil sands-related contaminants such as polycyclic aromatic hydrocarbons (PAHs) is assessed using passive air samplers. Measures of avian health are examined in relation to location of sampling and contaminants measured.

Waterfowl and mammals harvested and trapped at various locations in the oil sands region and in reference locations are assessed for contaminant burdens and toxicology. Wildlife samples are obtained from local hunters and trappers. Tissue samples are analysed for concentrations of oil sands-related contaminants (heavy metals, polycyclic aromatic hydrocarbons, and naphthenic acids). Dead and moribund birds collected from tailing ponds are also evaluated for levels and effects of contaminants.

Oil Sands Sediment Exposures of Embryo-larval Fathead Minnows

Dataset contains laboratory-studied fathead minnow egg and larval survival rates when exposed to sediments collected from 18 sites in the Athabasca watershed (2010-2014). A controlled laboratory study examined the impacts on fathead minnow eggs and larval development when exposed to collected sediments at concentrations of 1, 5 and/or 25 g/L. Sediments and water were renewed daily, and eggs were assessed as they hatched (in about 5 days), and as the larval fish grew to 8-9 days post hatch (dph), and 15-16 dph. The data in the file present the mean survival (and standard deviation).

The contaminants in fish database is a compilation of contaminant data analysed from fish tissue at the Fresh Water Institute from 1970 to 2005. Data include lab number, region, analysis, organs, species, lake, form (whole fish, headon dressed, headless dressed), weight, and length and contaminant concentrations. Total mercury was the predominant contaminant measured. Results were expressed as ppm or ppb based on the parameter analyzed.

Plant health assessments and vegetation surveys are undertaken at both terrestrial and wetland sites in the oil sands region and in reference areas. Plant monitoring is being conducted for biodiversity and contaminants, and because plants are important both as wildlife habitat and as traditional-use species. Plant and soil samples are collected at monitoring sites near and at varying distances from oil sands operations. Plant tissues are being examined for levels of naphthenic acids (NAs), polycyclic aromatic hydrocarbons (PAHs) and heavy metals.

Dataset contains laboratory-studied Fathead minnow (Pimephales promelas) survival when exposed to bitumen sediments from the oil sands region of northern Alberta, cut through the McMurray Formation (MF). These are the results of the toxicological exposures, when Fathead minnow embryos were exposed to water from simulated rainfall on the river sediments.

Fish health on British Columbia salmon farms is managed throughout the production cycle to maintain healthy fish populations and to identify and address disease occurrences as soon as they arise. Aquaculture licence conditions set out mandatory monitoring and reporting requirements to ensure any potential impacts are appropriately mitigated at salmon farms. A central component of on-farm fish health management is a Fish Health Management Plan (FHMP). FHMPs are approved by Fisheries and Oceans Canada (DFO) and describe the fish health principles that the licensee must follow to maintain fish health and biosecurity at the farm.

Aquatic bird eggs are being collected for contaminants analysis. Egg collections in the Peace-Athabasca Delta area support Parks Canada’s activities at Wood Buffalo National Park and the multi-stakeholder Peace-Athabasca Ecosystem Monitoring Program. This monitoring activity employs repeated censuses of birds and builds on initial egg collections made in 2009 from Egg Island (Lake Athabasca) and Wood Buffalo National Park, with the goal of evaluating contaminant burdens, contaminant sources and changes in sources through time. Egg samples are collected from colonial waterbirds California Gulls (Larus californicus), Herring Gulls (Larus argentatus), Ring-billed Gulls (Larus delawarensis), Caspian Terns (Hydroprogne caspia) and Common Terns (Sterna hirundo) and insectivorous birds Bank Swallows (Riparia riparia), Cliff Swallows (Petrochelidon pyrrhonota) and Tree Swallows (Tachycineta bicolor) to monitor health and contaminant levels of aquatic and terrestrial birds in the oil sands region and in reference areas.
