First, hair is well established and widely used as a biological marker
for MeHg exposure and was recommended as the measure of choice by the
World Health Organization. Hair correlates with brain levels and has a
smaller coefficient of variation (percent error) than
blood.1 Longitudinal analysis of hair allows the
recapitulation of exposure during the entire period of pregnancy.
