“…When compared with our previous findings for the Nenets Autonomous Region 13,14 and with the exception of As, the observed concentrations of the elements in the three additional fish species examined were comparable. www.nature.com/scientificreports www.nature.com/scientificreports/ Arsenic in Atlantic cod ranged from 3500 to 73500 µg/kg (ww) and a GM of 17800 µg/kg (ww).…”

“…We have previously published the concentrations of selected essential and toxic elements (namely, Cu, Co, Se, Zn, Ni, Hg, Pb, Cd, As) in muscle tissues of fish species collected in the Nenets Region of the European Russian Arctic 13,14 . The current study is an extension of these efforts.…”

“…As a component of a Russian mega-grant study to quantify the presence of POPs and Hg in food items consumed by pan-Russian Arctic indigenous populations, the amounts of essential and non-essential elements in fish species consumed were also quantified 13,14 . The latter included the non-metals As, Br, Se and I.…”

“…Despite the fact they have measured the Br content in a large number of fish species, only wet weight average concentrations (in mg/kg) were published: river fish (2.2 ± 1.6); salt-water fish (12.9 ± 8.8); shrimps (350 ± 227); and squid (24.4 ± 9.3). Previously we have reported the concentrations of selected toxic (As, Cd, Hg, Pb, Ni) and essential (Co, Cu, Se, Zn) elements measured in 7 fish species consumed by the indigenous peoples in the Nenets Autonomous Region within the Barents Sea region of the north-eastern part of European Russia 13,14 .…”

Fish muscle may constitute one of the main sources of iodine (I) for the indigenous peoples of the Russian Arctic, although limited information is available about its content in commonly consumed fish species. In the current study, bromine (Br), I, the essential elements (copper, selenium and zinc) and other non-essential elements-specifically mercury, arsenic (As), cadmium, lead and nickel-have been quantified in 10 fish species consumed by people living in the Nenets and Chukotka Regions. Fish muscle was analysed by ICP-MS after nitric acid or tetramethylammonium hydroxide digestion. Certified reference materials were employed and concentrations are reported as geometric means (GMs). Atlantic cod (6.32 mg/kg) and navaga (0.934 mg/kg) contained substantially higher amounts of I than all other fish species, while broad whitefish had the lowest (0.033 mg/kg). By comparison, navaga contained more Br (14.5 mg/kg) than the other fish species, ranging 7.45 mg/kg in Atlantic cod to 2.39 mg/kg in northern pike. A significant inter-fish association between As and I in freshwater and marine fish was observed, suggesting common sources and perhaps parallel absorption patterns. Only Atlantic cod and, to lesser extent, navaga constituted significant dietary sources of I.

“…The fish species were selected on the basis of a nutritional survey among the population of the village. According to the questionnaire, which was published earlier [23], the fish consumed by indigenous peoples in the area mainly belong to the families Salmonidae (62%) and Gadidae (15%). Salmon fish (pink salmon, Arctic char and humpback whitefish) and a representative cod (navaga) were bought from local fishermen in 2017-2018.…”

Currently, monitoring of persistent organic pollutant (POP) content in various biological and environmental matrixes in the Arctic is an urgent task. The present study focused on the determination of POPs such as: PCB#28, PCB#52, PCB#101, PCB#105, PCB#118, PCB#123, PCB#153, PCB#128, p,p’-DDE, o,p’-DDE, p,p’-DDD, o,p’-DDD, hexachlorobenzene (HCB), cis-nonachlor, trans-nonachlor, cis-chlordane, trans-chlordane, mirex, 1,2,3,5-tetrachlorobenzene and 1,2,4,5-tetrachlorobenzene in fish consumed by the indigenous people of the Nenets Autonomous Okrug (NAO) of the Russian Arctic. Fish samples were analyzed by gas chromatography triple quadrupole mass spectrometry (GC-MS/MS) using the multiple reaction monitoring (MRM) technique. The obtained results show that the major POPs in fish were dichlorodiphenyltrichloroethane (DDT) breakdown products and polychlorinated biphenyls (PCB) congeners. The ∑PCB8 in pink salmon, Arctic char, navaga, humpback whitefish and northern pike were 1.54, 1.58, 1.24, 0.72 and 0.32 ng/g (ww), respectively. The main PCB congeners maximum average medium concentrations were 0.68 ng/g (ww) and 0.51 ng/g (ww) of PCB#153 in navaga and PCB#128 in pink salmon, respectively. The main DDT breakdown product was p,p’-DDE. In Arctic char, pink salmon, navaga, humpback whitefish and northern pike, the concentration of p,p’-DDE was 0.58, 1.61, 0.49, 0.63 and 0.08 ng/g (ww), respectively. A moderate positive relationship between ∑PCB8 and lipid content and a high positive relationship between ∑DDT and lipid content were observed. In fish samples with fat content <0.5% (northern pike, humpback whitefish), the amount of analyzed POPs was 2 or more times lower than that in fish species with fat content >1% (pink salmon, Arctic char). Despite the large number of fish in the diet of indigenous peoples from NAO, no significant risks were identified. Most legacy POP and organochlorine pesticides (OCPs) tend to decrease, which can be explained by past national and regional bans and restriction on their use and emission.
