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.

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).

Venlafaxine is an antidepressant and anti-anxiety drug that has been detected in municipal wastewater at low concentrations. To assess the potential of this compound to affect the survival, development and reproductive capacity of fish, we exposed Fathead minnow (Pimephales promelas) over a full lifecycle in a flow-through system to nominal venlafaxine concentrations. During the 167–168 day exposure, no significant changes were observed in survival, or the weights and lengths of Fathead minnows. At maturity, there were no significant differences relative to controls in condition factor, liver-somatic index, or secondary sex characteristics in the venlafaxine exposed male or female fish.

Propranolol is a human pharmaceutical b-blocker that has been detected in municipal wastewater effluents in low concentrations. To assess the potential of this compound to affect fish, Fathead minnow (Pimephales promelas) were exposed for a life cycle in a flow-through system to nominal propranolol concentrations. During the 162-day to 165-day exposure, no significant changes in weights or lengths were seen in Fathead minnows, although the highest concentration of propranolol did cause a 15% decrease in survival of larval and juvenile stage fish compared with controls. At maturity, there were no significant changes in condition factor, liver-somatic index, or secondary sex characteristics in propranolol-exposed male or female fish.

Substituted phenylamine antioxidants (SPAs) are used in the production of a variety of consumer products (lubricants, dyes, and polymers). Substituted phenylamine antioxidants (SPAs) increase the life of consumer products by preventing the chain reaction of free radical production initiated by exposure to heat, oxygen, ozone, radiation and stress. It is important to consider that based on their physicochemical properties, substituted phenylamine antioxidants (SPAs) are likely to partition into sediment when they enter an aquatic system. Thus the most likely environmentally relevant pathway for fish to become exposed to SPAs would be through contaminated sediment.

This dataset contains the growth and survival data for Fathead minnow (Pimephales promelas) exposed to sediment from twelve sites within the Hamilton Harbour Area of Concern, as well as reference sediment (a mixture of sediment from two reference sites within Lake Erie, Long Point Marsh and Long Point Bay). The embryo-larval Fathead minnow exposure occurred over a three week period. Exposure was done from the egg stage (which lasted 5 days) to 9 and 16 days post hatch. Supplemental Information

Funding for this study was provided in part by the Government of Canada’s Great Lakes Action Plan (GLAP) and in support of Hamilton Harbour Area of Concern.

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.
