Arsenic Species and Nitrogen Stable Isotope Ratios in the Japanese Diet-Dietary Markers of Seafood.

ABSTRACT: Interest in seafood diet and health warrants a biomarker for seafood consumption. Nitrogen isotope ratio (¹⁵N/¹⁴N, expressed as δ¹⁵N (‱)) has been regarded as a biomarker for such a purpose. This study aims to elucidate the applicability of levels of arsenobetaine (AB), a non-toxic organic arsenic compound, in the diet as a marker of seafood abundance because of its known distribution in marine animals. The concentrations of AB and other arsenic species and δ¹⁵N in duplicate diet samples collected from 150 Japanese adults were analyzed for a possible relationship with the inclusion of seafood and seaweed in the diet samples. Information was collected from the menu reported from the duplicate diet donners, and a possible correlation between the le
