AB  - OBJECTIVES: The 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 DESIGN: A 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. METHODS: 
      Community-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. RESULTS: POPs 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. CONCLUSIONS: Based 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.
