Methylmercury in blood related to concentration of methylmercury in brain and total-Hg in toenails. Concentration of methylmercury in blood (C_{MeHg-Blood; μg Hg/L}) related to concentration of (a) methylmercury in occipital lobe cortex (C_{MeHg-Brain; μg Hg/kg}) and (b) concentration of total-Hg in toenails (C_{Hg-Toenail; μg Hg/kg}). The equations for the regression lines were (a) C_MeHg-Brain = 2.0 × C_MeHg-blood + 0.8, (correlation coefficient 0.725, n = 30, p < 0.001) and (b) C_Hg-toenail = 59 × C_MeHg-Blood + 125, (correlation coefficient 0.634, n = 29, p < 0.001).
