“…The CDC [175] informs that today there are approximately half a million U.S. children ages 1-5 with blood lead levels above 5 µg/dl, the reference level at which CDC recommends public health actions be initiated. In our review, lead showed morbidity when the levels in the blood were higher than 10µg/dl [136] and could cause alterations in language acquisition [135].…”

ResumoPesquisas mostram que a presença de metais, acima dos níveis permitidos pela legislação, representa riscos para a saúde humana. Crianças são mais vulneráveis aos efeitos do chumbo, que pode causar rebaixamento permanente da inteligência e outros distúrbios associados, como baixo desempenho escolar. O objetivo do estudo foi avaliar o rendimento escolar de crianças contaminadas por chumbo, comparando-o com o daquelas que não estavam contaminadas. Participaram três grupos com 25 crianças cada, de seis a treze anos; o Grupo 1, com crianças contaminadas por chumbo; o Grupo 2, com crianças com chumbo zero comprovado, embora residentes no local da contaminação; e o Grupo 3, com crianças de um bairro com características sociodemográficas semelhantes às do local da contaminação, porém, sem contaminação comprovada. Para a avaliação do rendimento escolar, utilizou-se o Teste de Desempenho Escolar -TDE. Os resultados mostraram melhor desempenho para o Grupo 2 (não contaminadas) e pior para o Grupo 1 (contaminadas). Palavras-chave: contaminação por chumbo, teste de desempenho escolar, rendimento escolar.

Lead (Pb) is a toxic heavy metal that is widely distributed throughout the environment. Pb is an important neurotoxic metal and children are more susceptible to its effect due to their higher absorption rate and greater susceptibility of the developing nervous system. In this work, we evaluated the lead exposure levels in children living near a metallurgical plant and identified risk factors associated with its internal dose. All children, aged 1-10 years and 11 months, living near a metallurgical plant in the great Salvador area, Brazil were evaluated in this cross-sectional study and compared with children from a non exposed area. Occipital hair and blood were used to assess exposure. Air lead levels in the respirable fraction (PM 2.5 ) were also measured in both areas. Blood lead levels (BLL), hair lead levels (PbH) and air lead were determined by graphite furnace atomic absorption spectrometry. Spearman correlations analysis was used to evaluate correlations between BLL, PbH and descriptors. Significant risk factors were modeled using multivariate linear regression analysis. Air lead levels were approximately tenfolds lower than EPA reference concentration (0.15 μg/m 3 ). Median BLL and PbH were1.65 ± 1.45 μg/dL and 1.26 ± 3.70 μg/g, respectively, in exposed children. In the referents, medians were BLL 1.20 ± 1.20 μg/dL; PbH 2.09 ± 2.06 μg/g. No significant difference was observed in biomarkers levels between boys and girls. It was observed a positive weak correlation (Spearman rho = 0.197, p = 0.033) between BLL and PbH. Our data show that children's lead body burden measured as BLL or PbH are low when compared with the recommended reference values. Despite that, we were able to identify four risk factors associated with increased biological lead levels: age, living near industrial site, environmental tobacco smoking and, above all, domestic waste burning. In order to prevent such avoidable exposure, environmental education and proper waste management should be implemented, especially in developing countries.
