Found 10 records similar to Amphibian and Wetland Health Contaminants and Toxicology, Oil Sands Region
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.
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.
The objectives of the fish component of the integrated oil sands monitoring program are to provide the necessary data/information to address key questions related to both environmental health of fish populations and fish health issues that can be used to inform human use and consumption.
The questions underlying the fish monitoring design are related to the status and health of wild fish populations in the Lower Athabasca River including and in an expanded geographical extent. Data is being collected to provide a baseline against which future changes in fish populations will be evaluated, and compared to data from historical studies to assess change over time to the current state. Data is also being collected in areas of new oil sands development, to develop baseline data for future site-specific comparisons, contribute to an expanded geographic basis of the overall monitoring plan, and contribute to an improved ability to examine cumulative effects.
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.
Water chemistry and 26 different metals were measured at 21 wetland sites where studies of amphibian health are being monitored. Water chemistry measurements (pH, conductivity, total dissolved solids, etc.) assess water quality, characterize the wetlands studied and allow for comparisons among the different types of wetlands monitored. The data show low concentrations of metals, with many metals undetectable.
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.
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.
Amphibians around the world are in decline and this has led to many international initiatives to monitor and catalog amphibian biodiversity.
The western toad (Bufo boreas) found in Jasper National Park is a species of special concern protected under the Federal Species at Risk Act (SARA). Jasper National Park conducts auditory and visual amphibian surveys to estimate species occurrence. Occupancy modelling of amphibians in the Park, using presence/absence data, provides a useful and flexible framework for population trend analyses and helps inform management.
Kootenay National Park samples 28 randomly selected potential amphibian breeding sites (out of possible 66) to determine presence or absence of amphibian species. Each of the 28 sites is visited 3 times every 2 years and all detected species are recorded.
Yoho National Park samples 28 randomly selected potential amphibian breeding sites (out of possible 66) to determine presence or absence of amphibian species. Each of the 28 sites is visited 3 times every 2 years and all detected species are recorded.
