Mercury is a naturally occurring element that is also present in the environment as a result of human activities. Water bodies can be contaminated with mercury from industrial sources, such as pulp and paper mills, and from the soil when large reservoirs are created by hydro-electric dams....

Restrictions in the utilization of polybrominated diphenyl ether (PBDE) mixtures have led to the increased usage of alternative flame retardant additives in a wide range of commercial applications. The present study examined the occurrence of established and emerging flame retardants (EFRs) in...

Ringed seals (Phoca hispida) have been used as bioindicator species of environmental contamination in Canada since the 1970s. In the present study, seals were harvested during subsistence hunts in four regions of the Canadian Arctic: Beaufort Sea, Arctic Archipelago, Hudson Bay, and coastal...

Freshwater mussels contribute important ecological functions to aquatic systems. The water filtered by mussel assemblages can improve water quality, and the mixing of sediments by burrowing mussels can improve oxygen content and release nutrients. However, nearly 70 percent of North American...

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...

Fish Status and Ecosystem Health - Caged Invertebrates In situ exposures of Hyalella azteca in Athabasca River tributaries - Summary of activities (2010, 2012, 2013, 2014) In situ exposures with Hyalella azteca were conducted within the oil sands region to assess differences in survival and...

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...

Verified and validated SPMD data are available on experimental research data to ascertain whether low concentrations of PACs can be more accurately detected using semi-permeable membrane devices than with water grab samples. Data are available from spring 2012 through winter 2014/15 from sites...

Wild fish community data (species, abundance, diversity, length, weight) for 2013 and 2019 are now available for tributaries of the Athabasca River (rivers Steepbank, Ells, Firebag, High Hills, Dunkirk, Horse, Muskeg, Tar and Calumet) and 2017 data for rivers and creeks adjacent to Christina Lake...
