Résumé :

The developmental consequences for children of prenatal and posnatal exposure to low levels of methylmercury (MeHg) from a maternal diet high in marine fish are not clear. Early studies reported an association between prenatal exposure to MeHg between 10 to 20 ppm in maternal hair and delayed cognitive and motor development in children. Two large prospectivve epidemiological studies are now under way, one in the Faroe Islands and the other in the Republic of Seychelles. Both studies are evaluating populations consuming seafood, but their exposure sources, designs, and other study details are different. The results of the second epidemiological study in the Republic of Seychelles were presented at the fifth international conference on mercury as a global polluant, Rio de Janeiro, Brazil, may 23-27,1999.
