I-Hg in brain related to I-Hg blood. Concentration of inorganic Hg in occipital cortex related to concentration of inorganic Hg blood. The correlation coefficient was not significant (r = -0.026, p = 0.891, n = 30). When the dental nurse (case 28, denoted with in the Figure) was excluded, the correlation coefficient was 0.253 (p = 0.186, n = 29).
