“…Among these entry routes, the diet is the major source of PCBs, especially fatty fish, meat and dairy products. PCBs have been detected in a suite of body tissues and fluids such as maternal and children’s blood and/or serum, cord blood, foetal adipose tissue, placenta, infant blood, blood from males and breast milk in Arctic peoples (AMAP 2015 ; Nøst et al 2013 ; Bonefeld-Jørgensen 2004 ; Donaldson et al 2010 ; Dudarev et al 2004 ; Hansen 2000 ; Klopov et al 1998 ; Nøst et al 2013 ). In the blood of breast-fed infants, the concentration may be many times higher than in maternal blood (Boucher et al 2010 ).…”

Polychlorinated biphenyls (PCBs) can be used as chemical sentinels for the assessment of anthropogenic influences on Arctic environmental change. We present an overview of studies on PCBs in the Arctic and combine these with the findings from ArcRisk—a major European Union-funded project aimed at examining the effects of climate change on the transport of contaminants to and their behaviour of in the Arctic—to provide a case study on the behaviour and impact of PCBs over time in the Arctic. PCBs in the Arctic have shown declining trends in the environment over the last few decades. Atmospheric long-range transport from secondary and primary sources is the major input of PCBs to the Arctic region. Modelling of the atmospheric PCB composition and behaviour showed some increases in environmental concentrations in a warmer Arctic, but the general decline in PCB levels is still the most prominent feature. ‘Within-Arctic’ processing of PCBs will be affected by climate change-related processes such as changing wet deposition. These in turn will influence biological exposure and uptake of PCBs. The pan-Arctic rivers draining large Arctic/sub-Arctic catchments provide a significant source of PCBs to the Arctic Ocean, although changes in hydrology/sediment transport combined with a changing marine environment remain areas of uncertainty with regard to PCB fate. Indirect effects of climate change on human exposure, such as a changing diet will influence and possibly reduce PCB exposure for indigenous peoples. Body burdens of PCBs have declined since the 1980s and are predicted to decline further.

“…The recommended safe intakes of traditional food items (see Table III ) are supported by the relatively high concentrations of POPs and mercury found in the blood of the residents of Uelen and Kanchalan ( 3 , 7 , 17 – 20 ). Since cigarette smoke is the main source of cadmium, consumption of offal (specifically liver and kidneys) is primarily an issue for smokers.…”

ObjectivesThe general aim was to assess dietary exposure to selected persistent organic pollutants (POPs) and metals among Eskimo (Inuit) and Chukchi of the Chukotka Peninsula of the Russian Arctic, and to establish recommendations for exposure risk reduction.Study designA cross-sectional evaluation of nutritional patterns of coastal and inland indigenous peoples of the Chukotka Autonomous Okrug (in 2001–2003); assessment of the levels of persistent toxic substances (PTSs) in traditional foods and their comparison to Russian food safety limits; the identification of local sources of food contamination; and the recommendation and implementation of risk management measures.MethodsCommunity-based dietary survey of self reported food frequencies (453 persons), chemical analyses (POPs and metals) of local foods and indoor matters (397 samples), substantiation of recommendations for daily (weekly, monthly) intakes of traditional food.ResultsPOPs in traditional food items are generally below the Russian food safety limits except marine mammal fat, while Hg and Cd are high mainly in mammal viscera. Lead is relatively low in tissues of all animals studied. For the Chukotka coastal communities, seals constitute the principal source of the whole suite of PTSs considered. Consumption restrictions are recommended for marine and freshwater fish, some wild meats (waterfowl and seal), fats (whale and seal), liver (most animals) and kidney (reindeer, walrus and seal). Evidence is presented that contamination of foodstuffs may be significantly increased during storing/processing/cooking of food due to indoor and outdoor environmental conditions.ConclusionsBased on the analytical findings and the local PTSs sources identified, guidelines on food safety are suggested, as well as measures to reduce food contamination and domestic and local sources. Important and urgent remedial actions are recommended to minimize PTSs environmental and domestic contamination. Waste clean-up activities started in coastal Chukotka in 2007.

A leverage points perspective on Arctic Indigenous food systems research: a systematic review

et al. 2023

View full text Add to dashboard Cite

Arctic food systems are increasingly challenged by rapid climate change, loss of food security and subsequent weakening of food sovereignty, and destabilization of Indigenous practices. Despite growing scientific knowledge on Arctic food systems, Indigenous communities continue to struggle with a plethora of sustainability challenges. To develop a systemic understanding of these challenges, we performed a systematic review of 526 articles published between 1998 and 2021 on Arctic Indigenous food systems. We used the leverage points framework to structure our analysis to understand to what extent the existing Western scientific body of literature provides the necessary knowledge to understand the food system characteristics that give rise to the current sustainability challenges. We combined deductive qualitative and inductive quantitative approaches to identify gaps in the systemic understanding of Arctic Indigenous food systems. We characterized existing research across the four levels of systemic depth—parameters, feedbacks, design, intent—and identified promising directions for future research. Our analyses show that research on food systems is clustered within six main domains, we term environmental contaminants, diet and health, food security, food culture and economy, changing socio-ecological systems and marine and coast. Based on our analysis, we identify three directions for future research that we believe to be of particular importance to enable sustainability transformations of Arctic Indigenous food systems: (i) the decolonization of research practices, (ii) acknowledging the significance of systemic interdependencies across shallow and deep leverage points, and (iii) transdisciplinary action-oriented research collaborations directing transformative system interventions.

Blood concentrations of persistent toxic substances in the indigenous communities of the Russian Arctic

Abstract: On the whole, PTS in human blood of the Russian Arctic natives are similar to those in the coastal areas of Greenland and Canada, and for some POPs such as toxaphenes and mirex, these levels are lower.
