To the Editor: The article by Dr Davidson and
colleagues1 presents an important public health issue but
is uninformative for several reasons. The mercury (Hg) content of the
mother's hair was used as an indicator of fetal exposure to
methylmercury (MeHg). However, a study in the Faroe
Islands2 showed that this biomarker does not correlate
closely with the Hg that has reached the fetal circulation. As
expected, the cord-blood concentration is a better overall predictor of
neurobehavioral risks.3
