Correlation coefficients of calculated mercury intake and whole blood mercury, and dietary FAs intake and erythrocyte membrane FAs. Values for Bland–Altman mean difference between biomarker and FFQ value with limits of agreement were transformed back by 10^x. Adult Inuit in Greenland 2005–2008 (n=2,224)
