chronic toxicity of oil sands Tailings Pond sediments to early life stages of fathead minnow pimephales promelas
Heliyon, 2019Co-Authors: Joanne L Parrott, J C Raine, Mark E Mcmaster, L M HewittAbstract:Abstract In this study fathead minnow (Pimephales promelas) embryo-larval stages were exposed to two oil sands Tailings Pond sediments which had previously been shown to decrease the survival of embryo-larval larval stages of walleye (Sander vitreus) and northern pike (Esox lucius). Fathead minnow are standard test species and we wanted to compare their sensitivity to the other two species. Fathead minnow larvae were exposed for 20 days (5 days in the egg stage and 15 days in the larval stage) with daily renewal of sediments and waters. Sediments contained polycyclic aromatic hydrocarbons (PAHs) and alkylated PAHs (APAHs). Results from an earlier study showed that Sediment 1 contained 173 μg/g total PAHs + APAHs (97 % alkylated), and sediment 2 contained 401 μg/g total PAHs + APAHs (95 % alkylated). Fathead minnow larvae exposed to oil sands Tailings Pond sediments had decreased survival, decreased weight, and increased deformities. Fathead minnow survival was unaffected at the embryo stage and at hatch. Most deaths occurred at the larval stages 1–8 days after hatching, showing the importance of exposing the fish for at least a week after hatch. Toxicity was seen at 0.2 g/L of sediment, which was equivalent to the addition of 35 and 80 μg total PAHs + APAHs to 1 L of overlying water for sediment 1 and 2, respectively. When compared to embryo-larval northern pike and walleye results from previous studies, all three species of fish resPonded more strongly to sediment 2 compared to sediment 1. For effects on lethality, fathead minnow were equally sensitive to pike, but walleye were 5–28 times more sensitive to the lethal effects of the sediments compared to both fathead minnow and pike. The study (and comparisons to our previous studies) shows the difference in sensitivity between a model laboratory species (fathead minnow) and some species of wild fish that are highly relevant to the oil sands area of Alberta.

oil sands Tailings Pond sediment toxicity to early life stages of northern pike esox lucius
Science of The Total Environment, 2018Co-Authors: J C Raine, D Turcotte, L Romanowski, Joanne L ParrottAbstract:Abstract The Athabasca River in Alberta flows through natural sources of eroding oil sands bitumen and oil sands mining operations that may result in low level contamination of surface waters. Northern pike (Esox lucius) are apex predators and important food and game fish species native to the Athabasca River system. This species has the potential to be exposed to both natural and anthropogenic sources of contamination from oil sands related materials throughout its life cycle. Pike are difficult to rear in the laboratory and little information exists on the toxicity of oil sands related materials to this key indigenous fish species. In this study, the potential effects of two sediment samples collected from different areas of one Tailings Pond in the Athabasca oil sands area are assessed in a daily renewal bioassay on early life stages of northern pike. Gametes were collected from spawning wild pike captured from a reference site outside of the oil sands area. Fertilized eggs were exposed to control water or increasing concentrations of Tailings Pond sediments for 21 days, coinciding with initiation of exogenous feeding and completion of yolk absorption. Developing fish were examined for survival and changes in body weight, length, and development. Embryos exhibited increased developmental abnormalities and decreased growth and survival with increasing sediment concentration. Both sediment samples had similar levels of naphthenic acids and similar types of PAHs, with alkylated PAHs dominating. However, concentrations of total and alkylated PAHs differed between sediment samples and were related to increasing developmental abnormalities and decreased growth and survival. This is consistent with developmental changes observed with exposure to PAHs in other fish species. These results provide information on the effects of Tailings Pond sediments comprising mixtures of PAHs and alkylated PAHs on the development and survival of a key species in the northern aquatic ecosystem.

the effect of oil sands Tailings Pond sediments on embryo larval walleye sander vitreus
Environmental Pollution, 2017Co-Authors: J C Raine, D Turcotte, V Tumber, Kerry M Peru, Zhendi Wang, Chun Yang, John V Headley, Joanne L ParrottAbstract:Walleye (Sander vitreus) are a commercially important North American fish species that inhabit the Athabasca River. This river flows through the Athabasca oil sands where natural sources of bitumen erode from the McMurray formation. Little information is available on responses of walleye embryos to oil sands Tailings Pond sediments in a laboratory setting. The current study describes the design and implementation of a daily-renewal bioassay to assess the potential effects of Tailings Pond sediments from the Athabasca oil sands area on walleye development. Developing walleye embryos were exposed to increasing concentrations of two Tailings Pond sediments (collected in the Athabasca oil sands area) until the completion of yolk absorption in control fish. Sediments from the Tailings Pond represent a mixture of polycyclic aromatic hydrocarbons (PAHs) and alkylated PAHs. During the 31 day exposure, the walleye were examined for mortalities, weight, length and developmental abnormalities to provide an initial evaluation of the effects of the oil sands Tailings Pond sediments. Walleye embryo survival differed between the Tailings Pond sediments, and survival decreased with increasing sediment concentration. Alkylated PAH content differed between the two Tailings Pond sediments and lower embryo survival corresPonded to higher total and alkylated PAH content. Tailings Pond sediment-exposed walleye exhibited a delay in development, as well as increased percentages of larvae with heart and yolk sac edema, and cranial and spinal malformations. These abnormalities in development are often associated with PAH and alkylated PAH exposure. This study provides an exposure design that can be used to assess sediment toxicity to early developmental stages of a fish species not commonly tested in the lab, and lays the groundwork for future studies with this and other difficult-to-culture species. These results offer information on the potential effects of Tailings Pond sediments containing PAH/alkylated PAH mixtures on walleye development and survival.

uptake of uranium by aquatic plants growing in fresh water ecosystem around uranium mill Tailings Pond at jaduguda india
Science of The Total Environment, 2016Co-Authors: R M Tripathi, N K Sethy, S K SahooAbstract:Concentration of uranium was determined in aquatic plants and substrate (sediment or water) of fresh water ecosystem on and around uranium mill Tailings Pond at Jaduguda, India. Aquatic plant/substrate concentration ratios (CRs) of uranium were estimated for different sites on and around the uranium mill Tailings disposal area. These sites include upstream and downstream side of surface water sources carrying the treated Tailings effluent, a small Pond inside Tailings disposal area and residual water of this area. Three types of plant groups were investigated namely algae (filamentous and non-filamentous), other free floating & water submerged and sediment rooted plants. Wide variability in concentration ratio was observed for different groups of plants studied. The filamentous algae uranium concentration was significantly correlated with that of water (r = 0.86, p < 0.003). For sediment rooted plants significant correlation was found between uranium concentration in plant and the substrate (r = 0.88, p < 0.001). Both for other free floating species and sediment rooted plants, uranium concentration was significantly correlated with Mn, Fe, and Ni concentration of plants (p < 0.01). Filamentous algae, Jussiaea and Pistia owing to their high bioproductivity, biomass, uranium accumulation and concentration ratio can be useful for prospecting phytoremediation of stream carrying treated or untreated uranium mill Tailings effluent.

assessment of environmental radioactivity at uranium mining processing and Tailings management facility at jaduguda india
Applied Radiation and Isotopes, 2008Co-Authors: R M Tripathi, S K Sahoo, V N Jha, A H Khan, V. D. PuranikAbstract:Abstract The uranium mines at Jaduguda and nearby areas of the Singhbhum thrust belt of Jharkhand State are the only operating mines in India, which supply fuel to nuclear power plants. The gamma radiation dose rates observed at different locations 1 m above the Tailings surface vary from 0.8 to 3.3 μGy h−1. The geometric mean activity concentration of 222Rn in air over the Tailings Ponds I and II were found to be 30 and 23 Bq m−3, respectively, but reduces to the local background level at the boundaries of the Tailings Ponds. The uranium and 226Ra levels in the ground water sources in the vicinity of the Tailings Pond are very similar to the regional average of 3.6 μg L–1 and 23 mBq L−1, respectively, indicating that there is no ground water migration of radioactive material from the Tailings Pond. This paper gives a brief account of the environmental radioactivity monitoring during uranium mining, ore processing and waste management operations.

methylicorpusculum oleiharenae gen nov sp nov an aerobic methanotroph isolated from an oil sands Tailings Pond
International Journal of Systematic and Evolutionary Microbiology, 2020Co-Authors: Ivica Tamas, Alireza Saidimehrabad, Dimitri K Kits, Peter Schumann, Roshan Khadka, Tania Strilets, Angela V Smirnova, Irene W C Rijpstra, Jaap Sinninghe S DamsteAbstract:An aerobic methane oxidizing bacterium, designated XLMV4T, was isolated from the oxic surface layer of an oil sands Tailings Pond in Alberta, Canada. Strain XLMV4T is capable of growth on methane and methanol as energy sources. NH4Cl and sodium nitrate are nitrogen sources. Cells are Gram-negative, beige to yellow-pigmented, motile (via a single polar flagellum), short rods 2.0–3.3 µm in length and 1.0–1.6 µm in width. A thick capsule is produced. Surface glycoprotein or cup shape proteins typical of the genera Methylococcus, Methylothermus and Methylomicrobium were not observed. Major isoprenoid quinones are Q-8 and Q-7 at an approximate molar ratio of 71 : 22. Major polar lipids are phosphoglycerol and ornithine lipids. Major fatty acids are C16 : 1 ω8+C16 : 1 ω7 (34 %), C16 : 1 ω5 (16 %), and C18 : 1 ω7 (11 %). Optimum growth is observed at pH 8.0 and 25 °C. The DNA G+C content based on a draft genome sequence is 46.7 mol%. Phylogenetic analysis of 16S rRNA genes and a larger set of conserved genes place strain XLMV4T within the class Gammaproteobacteria and family Methylococcaceae , most closely related to members of the genera Methylomicrobium and Methylobacter (95.0–97.1 % 16S rRNA gene sequence identity). In silico genomic predictions of DNA–DNA hybridization values of strain XLMV4T to the nearest phylogenetic neighbours were all below 26 %. On the basis of the data presented, strain XLMV4T is considered to represent a new genus and species for which the name Methylicorpusculum oleiharenae is proposed. Strain XLMV4T (=DSMZ DSM 27269=ATCC TSD-186) is the type strain.

oleiharenicola alkalitolerans gen nov sp nov a new member of the phylum verrucomicrobia isolated from an oilsands Tailings Pond
International Journal of Systematic and Evolutionary Microbiology, 2018Co-Authors: Fauziah F Rochman, Peter Schumann, Irene W C Rijpstra, Jaap Sinninghe S Damste, Tobin J Verbeke, Peter F DunfieldAbstract:A novel member of the phylum Verrucomicrobia was isolated from an oilsands Tailings Pond in Alberta, Canada. Cells of isolate NVTT are Gram-negative, strictly aerobic, non-pigmented, non-motile cocci to diplococci 0.5–1.0 µm in diameter. The bacterium is neutrophilic (optimum pH 6.0–8.0) but alkalitolerant, capable of growth between pH 5.5 and 11.0. The temperature range for growth is 15–40 °C (optimum 25–37 °C). Carbon and energy sources include sugars and organic acids. Nitrogen sources include nitrate, urea, l-glycine, l-alanine, l-proline and l-serine. Does not fix atmospheric nitrogen. Does not require NaCl and is inhibited at NaCl concentrations above 3.0 % (w/v). The DNA G+C content of strain NVTT, based on a draft genome sequence, is 66.1 mol%. MK-6 and MK-7 are the major respiratory quinones. Major cellular fatty acids are anteiso-C15 : 0 and iso-C15 : 0. Phylogenetic analysis of 16S rRNA gene sequences revealed that the strain belongs to the family Opitutaceae of the phylum Verrucomicrobia . The most closely related validated species is Opitutus terrae (93.7 % 16S rRNA gene sequence identity to its type strain PB90-1T). Based on genotypic, phenotypic and chemotaxonomic characteristics, it was concluded that this strain represents a novel genus and species, for which the name Oleiharenicola alkalitolerans gen. nov., sp. nov. is proposed. The type strain of this novel species is NVTT (=ATCC BAA-2697T;=DSM 29249T).
