Dietary exposure to persistent organic pollutants and metals among Inuit and Chukchi in Russian Arctic Chukotka
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 evalu...
