Description:

Objective:

We have shown that the Siberian Yu'pik people of St. Lawrence Island, Alaska have relatively high serum levels of PCBs and pesticides. This project will examine traditional foods of the Yu'pik people for PCBs, three pesticides and several metals in order to determine which are the most significant sources of exposure, and how preparation for consumption influences the level of contaminants.

Approach:

We will obtain multiple samples of traditional foods (seal, whale, walrus, fish, seal oil, greens, sea bird eggs, berries), including various parts of animals, for congener-specific measurement of PCBs and levels of pesticides and metals. We will compare levels in raw foods and in foods after preparation for consumption.

Expected Results:

We expect to demonstrate higher levels of contaminants in some foods than in others, and in some parts of food animals than in others. We expect to find levels of contaminants to be different in some foods if they come from more contaminated areas. We also expect to demonstrate that preparation of the food for consumption will alter contaminant levels. This information will be critical to the community to help individual members make choices about what they eat so they may reduce their exposure to environmental contaminants.
