Iodine and bromine in fish consumed by indigenous peoples of the Russian Arctic.

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.

Concentration dataset for 4 essential and 5 non-essential elements in fish collected in Arctic and sub-Arctic territories of the Nenets Autonomous and Arkhangelsk regions of Russia.

The raw concentration data for the research article entitled "Essential and non-essential trace elements in fish consumed by indigenous peoples of the European Russian Arctic" (Sobolev et al., 2019) [1] are herein presented. Fifteen fish species were collected in the Nenets Autonomous and Arkhangelsk Regions of the Russian Federation and were analysed for 9 elements (As, Cd, Co, Cu, Hg, Ni, Pb, Se and Zn).

Essential and non-essential trace elements in fish consumed by indigenous peoples of the European Russian Arctic.

In present study, the analyses of essential [copper (Cu), cobalt (Co), selenium (Se) and zinc (Zn)] and non-essential elements [mercury (Hg), lead (Pb), cadmium (Cd) and arsenic (As)] in 7 fish species consumed by the indigenous people of the European Russia Arctic were conducted. The Nenets Autonomous Region, which is located in the north-eastern part of European Russia, was chosen as a Region of interest. Within it, the Nenets indigenous group (n = 6000) constitutes approximately 10% of the total population.

A study of atherothrombotic biomarkers in welders.

Introduction: Studies have shown that welders have increased cardiovascular mortality. This may be due to airborne particulate matter (PM) exposure. Elevated levels of PM in polluted urban air have been associated with increased cardiovascular mortality and morbidity.

Neurobehavioral performance of patients diagnosed with manganism and idiopathic Parkinson disease.

Purpose: There is a lack of knowledge about neurobehavioral performance among patients with manganism and how their performance differs from that of idiopathic Parkinson disease patients (PD). This study was initiated with the aim to describe and compare neurobehavioral performance among patients diagnosed with manganism, PD and a group of referents.

Materials And Methods: Neurobehavioral performance was assessed in 34 patients diagnosed with manganism, 13 with PD, and 43 healthy workers (turners/fitters) who served as the reference group.

The Impact of a Nickel-Copper Smelter on Concentrations of Toxic Elements in Local Wild Food from the Norwegian, Finnish, and Russian Border Regions.

Toxic elements emitted from the Pechenganickel complex on the Kola Peninsula have caused concern about potential effects on local wild food in the border regions between Norway, Finland and Russia. The aim of this study was to assess Ni, Cu, Co, As, Pb, Cd, and Hg concentrations in local wild foods from these border regions. During 2013-2014, we collected samples of different berry, mushroom, fish, and game species from sites at varying distances from the Ni-Cu smelter in all three border regions.

Biological monitoring of welders' exposure to chromium, molybdenum, tungsten and vanadium.

Background: Welders are exposed to a number of metallic elements during work. Bioaccessability, that is important for element uptake, has been little studied. This study addresses bioaccessability and uptake of chromium (Cr), molybdenum (Mo), tungsten (W) and vanadium (V) among welders.

A follow-up study of neurobehavioral functions in welders exposed to manganese.

Welders may be exposed to high amounts of manganese (Mn). In this study 63 welders and 65 referents were followed up with neurobehavioral tests approximately 6 years after the initial examination at baseline. The welders were exposed to the geometric mean (GM) Mn concentration of 116μg/m(3) at baseline and 148μg/m(3) at follow-up.

Biomarkers of iron status and trace elements in welders.

Iron status was studied in 137 welders exposed to a geometric mean (GM) air concentration of 214 μg/m(3) (range 1-3230) of manganese (Mn), in 137 referents and in 34 former welders. The GM concentrations of S-ferritin were 119 (3-1498), 112 (9-1277) and 98 (12-989) μg/L (p=0.24) in the three groups, respectively.

The interaction between manganese exposure and alcohol on neurobehavioral outcomes in welders.

Neurobehavioral functions were studied in 137 welders exposed to the geometric mean (GM) air concentration of 214 μg/m(3) (range 1-3230) of manganese (Mn) based on the individual mean from two days of air sampling. Only 22 μg/m(3) (GM) was soluble in the artificial lung fluid Hatch solution. The welders were compared to 137 referents (turner/fitters) recruited from the same plants.

Cancer mortality in the indigenous population of coastal Chukotka, 1961-1990.

Objectives: The general aim was to assess the pattern and trend in cancer mortality among the indigenous people of coastal Chukotka during the period 1961-1990.

Methods: All cases of cancer deaths of indigenous residents of the Chukotsky district in the north-easternmost coast of Chukotka Autonomous Okrug were copied from personal death certificates. There were a total of 219 cancer deaths during the study period.

Occupational diseases in Murmansk Oblast: 1980-2010.

Background: Official statistics tend to underestimate the incidence of occupational disease (OD) nationally and regionally in Russia.

Objectives: The general aim was to obtain an accurate estimate of ODs in Murmansk Oblast in 1980-2010 and to determine the rate of specific types of ODs among cohorts of workers who had been exposed to the hazardous factors causing the disease.

Materials And Methods: Data were retrieved from the Murmansk Oblast ODs database for the oblast and 2 enterprises--Apatite JSC and Kolskaya MSC--which contributed to more than half of the ODs in the oblast in 1980-2010.

Occupational health and health care in Russia and Russian Arctic: 1980-2010.

Background: There is a paradox in Russia and its Arctic regions which reports extremely low rates of occupational diseases (ODs), far below those of other socially and economically advanced circumpolar countries. Yet, there is widespread disregard for occupational health regulations and neglect of basic occupational health services across many industrial enterprises.

Study Design And Methods: This review article presents official statistics and summarises the results of a search of peer-reviewed scientific literature published in Russia on ODs and occupational health care in Russia and the Russian Arctic, within the period 1980-2010.

Occupational accidents in Russia and the Russian Arctic.

Background: According to official statistics, the rate of occupational accidents (OAs) and fatal injuries in Russia decreased about 5-fold and 2-fold, respectively, from 1975 to 2010, but working conditions during this period had the opposite trend; for example, the number of people who work in unfavourable and hazardous conditions (particularly since 1991) has increased significantly.

Methods: This review summarises the results of a search of the relevant peer-reviewed literature published in Russia and official statistics on OAs and occupational safety in Russia and the Russian Arctic in 1980-2010.

Results: The occupational safety system in Russia has severely deteriorated in the last 2 decades, with legislators tending to promote the interests of industry and business, resulting in the neglect of occupational safety and violation of workers' rights.

Health and society in Chukotka: an overview.

This study provides a historical overview of the changes in the socio-economic and health status of the population of Chukotka, from the Soviet to the post-Soviet period, with special attention paid to the circumstances of indigenous people. Past health studies in Chukotka are reviewed and key demographic and health indicator data presented. Since the 1990s, Chukotka's population has shrunk to a third of its former size due to emigration of non-indigenous and mostly younger people, with a corresponding increase in the mortality rate due to aging of the population.

Cancer incidence and mortality in Chukotka, 1997-2010.

Objectives: The general aim was to assess cancer incidence and mortality among the general population of Chukotka in 1997-2010 and to compare it with the population of Russia.

Methods: Cancer data were abstracted from the annual statistical reports of the P.A.
