Data are contaminants in tissue of caged mussels put in the river for 3 weeks at about 25 stations located on the Canadian and US side of the river. The main objective of the study is to identify contaminant sources, or source areas requiring more detailed follow-up investigations, based on the level  of contaminants in the mussels. Compounds monitored include: * organochlorinated pesticides * Polychlorinated biphenyls * dioxins/furan * chlorinated benzenes * Polycyclic aromatic hydrocarbons * industrial organic compounds

These data contain the results of chronic toxicity tests with perfluorooctanoic acid (PFOA) to Hyalella azteca and Fathead minnow (Pimephales promelas) to set a PFOA freshwater target concentration for cleanup of industrial sites.

The bioaccumulation of a broad range of pharmaceuticals and personal care product chemicals (PPCPs) was studied in Cootes Paradise Marsh (CPM), an urban wetland that receives tertiary treated municipal waste waters as well as urban storm runoff. PPCPs were measured in caged and wild goldfish, as well as wild carp, and compared to observed bioaccumulation factors (BAFs) using concentrations in surface waters and fish blood plasma, with modeled BAFs. Thirty-two PPCPs were detected in water from the central CPM site (CPM3) while 64 PPCPs were found at higher concentrations at a site immediately downstream of the effluent outflow (CPM1). Following a 3-week deployment, 15 PPCPs were detected in the plasma of caged goldfish at CPM1, and 14 at CPM3, compared to only 3 in goldfish caged at a reference site.

The toxicity of pharmaceuticals finasteride (FIN) and melengestrol acetate (MGA) was assessed in chronic (42 days) sediment tests with the amphipod Hyalella azteca. Two tests were completed for each compound. Survival, growth, reproduction and sex ratio were assessed at the end of each test.

The toxicity of pharmaceuticals finasteride (FIN) and melengestrol acetate (MGA) was assessed in freshwater mussels, including acute (48 h) aqueous tests with glochidia from Lampsilis siliquoidea, a sub-chronic (14 days) sediment test with gravid Lampsilis fasciola, chronic (28 days) sediment tests with juvenile L. siliquoidea, and in chronic (42 days) sediment tests with the amphipod Hyalella azteca and the mayfly Hexagenia spp. Testing with mussels assessed survival (glochidia, juvenile mussels), burial ability (juvenile mussels), and filtering and luring behaviour, and viability of brooding glochidia (gravid mussels). Testing with amphipods assessed survival, growth, reproduction and sex ratio. Testing with mayflies assessed survival and growth.

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).

Towfish (sidescan and video) and echo sounder surveys were utilized to examine bottom type and macrophyte cover within the area of two coastal marine finfish aquaculture sites, one in New Brunswick (Welch Cove) and one in Nova Scotia (Jordan Bay). Both towfish and echo sounder data could be used independently of one another. However, the towfish data were very useful for ground truthing echo sounder based classifications. All survey data were placed into a GIS which could be used to answer management questions such as the placement of cages at sites, benthic impacts and baseline conditions to determine long term changes.

To assess the toxicity of winter-time atmospheric deposition in the oil sands mining area of Northern Alberta, embryo-larval fathead minnow (Pimephales promelas) were exposed to snowmelt samples. Snow was collected in 2011–2014 near (< 7 km) oil sands open pit mining operations in the Athabasca River watershed and at sites far from (> 25 km) oil sands mining. Snow was shipped frozen back to the laboratory, melted, and amended with essential ions prior to testing. Fertilized fathead minnow eggs were exposed (< 24 h post-fertilization to 7–16 days post-hatch) to a range of 25%–100% snowmelt.
