Item Acesso aberto (Open Access) Avaliação da exposição ao mercúrio e seus compostos em mães e seus recém-nascidos em Porto Velho - RO(Universidade Federal do Pará, 2002-06-26) CEZAR, Marinês Rodrigues dos Santos; AMORIM, Marúcia Irena Medeiros de; http://lattes.cnpq.br/6969908284845675A hundred and three binomials mother-son bomed in hospitaIs of the city of Porto Velho - RO, during the months of November/2000 up to February/2001. Samples of the mother's hair were analyzed and of the newly born, maternal blood, placenta and umbilical cord. The collections of the samples were accomplished in the moment of the childbirth. A questionnaire was applied to mother where enrolled important information for the risk of contamination mercurial and/or congenital anomaly. The products of the gestation that presented congenital anomaly were included in the study. The measure of the exhibition to the Methylmercury was made using the collected biologic marker and accomplishment of techniques through the method of spectofotometric of atomic absorption for the cold vapor. The practical factor of total conversion was used in mercury that is from 0,90 to 0,92. After analysis and statistical study the main conclusions were: the alcoholic drink consumption during the pregnancy, and other variables, didn't influence in the congenital anomaly apparently, mainly neural tube defects (NTD); most of the found congenital anomaly was NTD (66,6%) that were significant correlated with the levels of total mercury in the hair of the newly born; the levels of total mercury, in the placenta and in the umbilical cord, they were equivalent.Item Acesso aberto (Open Access) Avaliação da exposição ao mercúrio e seus compostos sobre o desenvolvimento neuropsicomotor em crianças de Porto Velho-RO(Universidade Federal do Pará, 2002-06-27) MARQUES, Rejane Corrêa; AMORIM, Marúcia Irena Medeiros de; http://lattes.cnpq.br/6969908284845675A cohort of 100 births was generated during november and december of 2000 in Porto Velho city. Mothers and her newborns had been examined to verify total mercury levels (TML) at the birth, and the course of posnatal exposure on development and growth of infants during the first semester of their extrauterine life. To evaluation of prenatal exposure TML at the birth in samples of maternal and newborns hair, placenta, umbilical coord, and maternal blood had been analyzed. The newborns underwent physical and clinical examination. Mothers answered a questionnare that included important infonnations about risk factors to mercury accumulation or that could affect the development and growth of her childrens. At six months of age, 86 of the infants underwent detailed phisical and neurobehavioral examination, to evaluate the postnatal exposure. Besides a new sample of infants hair had been analyzed to verify TML. All data had been analyzed, compared, and underwent statistical evaluation. 23 infants (26%) showed neurological developmental disturbance at six months of age. This had been correlated with TML in children hair as at birth as at 6 months of age. A statistically significant correlation was observed between the head circumference and TML' s in the several analyzed samples.Item Acesso aberto (Open Access) Avaliação da exposição congênita ao mercúrio sobre o peso de recém-nascidos em Porto Velho-Rondônia(Universidade Federal do Pará, 2003) RAMOS, Teresa Cristina; AMORIM, Marúcia Irena Medeiros de; http://lattes.cnpq.br/6969908284845675A hundred mothers with their newborn babies, were studied, in three hospitals in the city of Porto Velho, for the evaluation of the prenatal exposure to mercury, through the study of the mercury level in the birth, the mother and newborn’s hair, mother’s blood, umbilical cord and placentas samples. 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.
