Lead and manganese are regulated in drinking water due to their neurotoxicity. These elements have been reported co-occur systems, accordance with the metal-scavenging properties of MnO2. To extent that is a driver lead release, controlling it during treatment may reduce levels. We investigated transport at tap full-scale distribution system: consistent cotransport phenomenon, two metals were detected same colloidal size fraction by size-exclusion chromatography multielement detection. also...
Ringed seals (Pusa hispida) are a key food resource for Inuit communities in Nunavut, Canada, thus justifying the need regular monitoring of environmental contaminants these animals. The primary objective this study was to determine current levels some non-essential trace elements, including cadmium (Cd), total mercury (THg), and methylmercury (MeHg), polychlorinated biphenyls (PCBs) polybrominated diphenyl ethers (PBDEs) ringed eastern Nunavut. Selenium (Se), an essential element, also...
We show that lead is associated with natural organic matter and colloidal iron at the tap. Removing these species during treatment could reduce exposure.
Understanding the effects of climatic variability on marine mammals is challenging due to complexity ecological interactions. We used general linear models analyze a 15-year database documenting mammal strandings (1994–2008; n = 1,193) and nine environmental parameters known affect survival, from regional (sea ice) continental scales (North Atlantic Oscillation, NAO). Stranding events were more frequent during summer fall than other seasons, have increased since 1994. Poor ice conditions...
Abstract While intra‐population variability in resource use is ubiquitous, little known of how this measure niche diversity varies space and its role population dynamics. Here we examined heterogeneous breeding environments can structure variation both reproductive output. We investigated the Arctic tundra ecosystem, studying peregrine falcon ( F alco peregrinus tundrius, White) within a terrestrial‐marine gradient near Rankin Inlet, Nunavut, C anada. Using stable isotope analysis, found...
Access to clean and safe drinking water is a perpetual concern in Arctic communities because of challenging climatic conditions, limited options for the transportation equipment process chemicals, ongoing effects colonialism. Water samples were gathered from multiple locations decentralized trucked system Nunavut, Canada, over course one year. The results indicate that point use quality was impacted by conditions source individual buildings strongly suggest lead copper measured at tap...
Drinking water samples were collected from the source, delivery truck, domestic storage tanks, and at point of use in a decentralized drinking system Pond Inlet, Nunavut, predominantly Inuit community Canada's Arctic region.
Narwhals (Monodon monoceros Linnaeus, 1758) summering on northern Baffin Island are experiencing increases in vessel traffic related to an iron-ore mine operated by Baffinland Iron Mines Corporation; how this increase may impact narwhal is currently unknown. Cortisol a stress response hormone and indicator marine mammals. This study evaluated cortisol levels blubber sampled during subsistence harvests prior project-related (2000–2006), (2013–2019), high-stress entrapment event that occurred...
Climate-induced alterations to Arctic sea ice dynamics are influencing resource availability and distribution, in turn, restructuring marine food webs, which can be monitored by studying the foraging ecology of opportunistic predators such as anadromous char ( Salvelinus alpinus). Despite its subsistence economic importance, across their range, particularly relation dynamics, remains understudied. Here, we investigate near communities Rankin Inlet Naujaat along western Hudson Bay, using...
Rationale Stable isotope analysis is widely used to reconstruct diet, delineate trophic interactions, and determine energy pathways. Such ecological inferences are based on the idea that animals are, isotopically, what they eat but with a predictable difference between isotopic ratio of consumer its coined as discrimination factor. Providing correct estimates diet‐consumer in controlled conditions key for robust application stable isotopes technique wild. Methods Using Finnigan Mat Delta...
Le déclin historique du faucon pèlerin ( Falco peregrinus ) observé en Amérique Nord au milieu xx e siècle a été principalement attribué à l’échec de reproduction causé par les polluants organochlorés persistants. C’est dans ce contexte que le Arctic Raptor Project initié, 1982, but d’étudier la faucons pèlerins F.p. tundrius nichant l’Arctique. Nous présentons ici une synthèse des principaux travaux conduits cadre programme recherche réalisé essentiellement région Rankin Inlet, mais aussi...
Ringed seals (Pusa hispida) (nattiq (s.), nattiit (pl.) [Inuktut]) provide an important food staple for Nunavummiut (Indigenous residents of Nunavut). We studied the health harvested by hunters from Baffin Island, Nunavut, via Inuit Qaujimajatuqangit and veterinary science. conducted serological surveys polymerase chain reaction (PCR) select zoonotic pathogens, including Brucella spp., Erysipelothrix rhusiopathiae, Leptospira interrogans, Toxoplasma gondii, in 55 Frobisher Bay (FB) 58...
Parasites are fundamental components within all ecosystems, shaping interaction webs, host population dynamics and behaviour. Despite this, baseline data is lacking to understand the parasite ecology of many Arctic species, including wolverine (Gulogulo), a top predator scavenger. Here, we combined traditional count methods (i.e. adult helminth recovery, where taxonomy was confirmed by molecular identification) with 18S rRNA high-throughput sequencing document community. Further,...
<title>Abstract</title> Salmonid fishes exhibit marked intra-specific variation in muscle pigmentation. This is primarily due to individual differences the accumulation and assimilation of dietary carotenoids synthesized by primary producers microorganisms present tissues crustaceans that can serve as important prey for salmonids. Despite anadromous Arctic char (<italic>Salvelinus alpinus</italic>) being a key subsistence economic resource across Inuit Nunangat, their pigmentation relation...
