Concentration of methylmercury in brain related to concentration of total-Hg in toenails. Concentration of methylmercury in occipital lobe cortex (C_{MeHg-Brain; μg Hg/kg}) related to concentration of total-Hg in toenails (C_{Hg-Toenail; μg Hg/kg}). The equation for the regression line was C_MeHg-Brain = 0.017 × C_Hg-toenail + 1.5, and the correlation coefficient was 0.586 (n = 29, p = 0.001).
