Traditional Diet and Environmental Contaminants in Coastal Chukotka I: Study Design and Dietary Patterns

Abstract

The article is the first in the series of four that present the results of a study on environmental contaminants in coastal Chukotka, conducted in the context of a multi-disciplinary investigation of indigenous foodways in the region of the Bering Strait. We provide an overview of the contemporary foodways in our study region and present the results of the survey on the consumption of locally harvested foods, carried out in 2016 in the Chukotkan communities of Enmelen, Nunligran, and Sireniki. The present results are evaluated in comparison to those of the analyses carried out in 2001–2002 in the village of Uelen, located further north. Where appropriate, we also draw comparative insight from the Alaskan side of the Bering Strait. The article sets the stage for the analyses of legacy persistent organic pollutants (POPs) and metals to which the residents become exposed through diet and other practices embedded in the local foodways, and for the discussion of the Recommended Food Daily Intake Limits (RFDILs) of the food that has been sampled and analyzed in the current study.
