PTS levels in biota and biomagnification in food chains
These two aims place somewhat different requirements on sampling, sample treatment, and analysis. For the first objective, in order to estimate PTS intake with food, it is necessary to obtain as reliable and representative data as possible on PTS levels in those species and tissues that are widely used as traditional food. For the second objective, it is necessary to determine the average levels of contamination in species representing a range of trophic levels (and in specific tissues of organisms at higher trophic levels), and from this information, evaluate the degree to which PTS are being accumulated and biomagnified in the various food chains that form the basis for food items in the traditional diet.
