The mothers answered a questionnaire, with the objective of identifying risk factors of mercury contamination and all children were subjected to the routine physical examination. The mercury analysis was carried in the Environmental Biogeochemical Laboratory of UNIR, through the spectrophotometry of atomic absorption technique, the results showed significant correlation among the total mercury concentration in the placenta and the umbilical cord, newborn hair, the mother’s blood and hair. We concluded that there was a congenit exposure, that the levels of concentration of this metal observed, in the study, didn’t affect directly on pregnantable age; but, showed significant connection between the mercury and concentration and the newborn weight , confirmed by the results found in the newborn’s hair.porAcesso AbertoExposição (Poluição)Exposição maternaIdade gestacionalRecém-nascidoPeso ao nascerMercúrioRio Madeira (Bacia do Amazonas)Porto Velho - RORoraima - EstadoAmazônia brasileiraDissertaçãoCNPQ::CIENCIAS DA SAUDE::SAUDE COLETIVA::SAUDE PUBLICACNPQ::CIENCIAS DA SAUDE::MEDICINA::CLINICA MEDICA::DOENCAS INFECCIOSAS E PARASITARIAS
