Hair mercury isotopes, a noninvasive biomarker for dietary methylmercury exposure and biological uptake.

ABSTRACT: Background. Fish and rice are the main dietary sources of methylmercury (MeHg); however, rice does not contain the same beneficial nutrients as fish, and these differences can impact the observed health effects of MeHg. Hence, it is important to validate a biomarker, which can distinguish among dietary MeHg sources. Methods. Mercury (Hg) stable isotopes were analyzed in hair samples from peripartum mothers in China (n = 265). Associations between mass dependent fractionation (MDF) (δ²⁰²Hg) and mass independent fractionation (MIF) (Δ¹⁹⁹Hg) (dependent variables) and dietary MeHg intake (independent variable) were investigated using multivariable regression models. Results. In adjusted models, hair Δ¹⁹⁹Hg was po
