Uranium and Arsenic Spatial Distribution in the Águeda Watershed Groundwater

Documento originalmente apresentado em International workshop “Uranium, Environment and Public Health”, UrEnv 2013.The high spatial variability of groundwater contaminants is a non-stationary process, as spatial variability is strongly dependent on several externalities. The herein work shows a first approach to the construction of spatial distribution patterns for sensitive contaminants in groundwater, within the transboundary watershed of the Águeda River. The obtained results points out to the old mining activities as a serious environmental risk factor. The obtained maps showed to be suited for assessing the environmental impact of the considered contaminants and could facilitate the improvement of local groundwater systems’ management and the development of specific monitoring activities

Ingestão de alimentos e adequação de nutrientes no final da infância Food intake and nutritional adequacy in final phase of childhood

Este trabalho reúne informações sobre a ingestão de alimentos e a adequação dos nutrientes no período final da infância. O grupo estudado foi composto por 247 escolares, sendo 150 do sexo feminino e 97 do masculino, com idade de nove e dez anos, pertencentes a escolas públicas municipais de Maceió. Os dados sobre ingestão de alimentos foram coletados através do recordatório de 24 horas e comparados com as recomendações preconizadas pelo National Research Council de 1989. De acordo com os resultados, a ingestão alimentar dos escolares apresentou-se deficiente em relação à energia e aos micronutrientes, especialmente as vitaminas e alguns minerais pesquisados, com exceção do ferro. Essa deficiência foi encontrada independente do sexo. Tais achados sugerem que o aporte insuficiente dos nutrientes estudados, se persistente, poderá contribuir negativamente para o desempenho do crescimento linear durante a fase da adolescência.<br>This study analyzes the results of a dietary intake survey. The main goal was to estimate the nutrient and energy intake of children in final phase of childhood and the nutritional adequacy of their diet. The studied group was composed of 247 schoolchildren (150 females and 97 males, aged nine to ten years old) from public schools of the city of Maceió, state of Alagoas. Food intake data were collected through a 24-hour dietary recall and compared with the standards of National Research Council-Recommended Dietary Allowances (RDA, 1989). According to the results, the children food intake, independently of the sex, was deficient in energy and micronutrients, specially vitamins and some minerals, with the exception of iron. These findings suggest that in this group specific nutrients deficits can be a limiting factor which may contribute to an inadequate growth performance during adolescence
