Chronic Toxicity of Surface Water from a Canadian Oil Sands End Pit Lake to the Freshwater Invertebrates Chironomus dilutus and Ceriodaphnia dubia.

Arch Environ Contam Toxicol 2020 Apr 20;78(3):439-450. Epub 2020 Feb 20.

Toxicology Centre, University of Saskatchewan, 44 Campus Dr., Saskatoon, SK, S7N 5B3, Canada.

Permanent reclamation of tailings generated by surface mining in the Canadian oil sands may be achieved through the creation of end pit lakes (EPLs) in which tailings are stored in mined-out pits and capped with water. However, these tailings contain high concentrations of dissolved organics, metals, and salts, and thus surface water quality of EPLs is a significant concern. This is the first study to investigate the chronic toxicity of surface water from Base Mine Lake (BML), the Canadian oil sands first large-scale EPL, to aquatic invertebrates that play a vital role in the early development of aquatic ecosystems (Chironomus dilutus and Ceriodaphnia dubia).

Mercury Levels in Freshwater Fish: Estimating Concentration with Fish Length to Determine Exposures Through Fish Consumption.

Arch Environ Contam Toxicol 2020 May 11;78(4):604-621. Epub 2020 Feb 11.

Department of Biological Sciences, Dartmouth College, HB 6044, 78 College Street, Hanover, NH, 03755, USA.

Methylmercury (MeHg) is a neurotoxic pollutant that bioaccumulates and biomagnifies in aquatic food webs, impacting the health of piscivorous wildlife and human consumers of predatory fish. While fish mercury levels have been correlated with various biotic and abiotic factors, many studies only measure adults to characterize the health of locally fished populations, omitting information about how local fish bioaccumulate mercury relative to their growth. In this study, we sought to establish length: total mercury (THg) concentration relationships in juvenile and adult fish of four genera (sunfish, yellow perch, white perch, and killifish) across six freshwater pond systems of Nantucket Island to determine safe consumption sizes across species and environmental conditions.

Comparative Toxicity of Nitrate to Common and Imperiled Freshwater Mussel Glochidia and Larval Fishes.

Arch Environ Contam Toxicol 2020 May 1;78(4):536-544. Epub 2020 Feb 1.

Interdisciplinary Toxicology Program, University of Georgia, Athens, GA, USA.

Growing human populations and increasingly intensive agriculture have resulted in widespread aquatic nitrate pollution. Freshwater mussel populations have been in decline for decades but often are underrepresented in data used for the development of ambient water quality criteria and acute toxicity of nitrate to mussel glochidia has not yet been established. Additionally, toxicity testing with aquatic species often is limited to a few model species; however, relatively little is known about how representative model species are of imperiled species.

Integrated Assessment of Bioconcentration, Toxicity, and Hazards of Chlorobenzenes in the Aquatic Environment.

Arch Environ Contam Toxicol 2020 Feb 2;78(2):216-229. Epub 2020 Jan 2.

School of Environment and Science, Griffith University, Brisbane, QLD, 4111, Australia.

The evaluation of bioconcentration, toxicity, and hazard (BTH) of persistent lipophilic organic compounds (LOCs) are generally performed as separate rather than integrated assessments. There are adequate data sets in the literature for chlorobenzenes (CBs) consisting of (a) concentrations in aquatic biota (C) and water (C) in the natural environment, (b) laboratory-derived bioconcentration factors (K) and field concentration ratios (CR), the field equivalent factor of K, (c) measured internal lethal concentrations (ILC) and model estimated ILC calculated from K and lethal concentrations (LC), and (d) calculated hazard quotients in aquatic biota (HQ) and in water (HQ). However, there have been no integrated studies of those parameter values based on the respective lipid-based parameters (C, K, CR, ILC, HQ) performed. Read More
