Intoxicación plúmbica crónica y su relación con problemas de anemia en trabajadores de Siderperu

Vásquez Corales, Edison January 2015 (has links)
Introducción: El plomo inhibe la síntesis del grupo hemo y en consecuencia de la hemoglobina. Objetivos: Evaluar la intoxicación plúmbica crónica y su relación con problemas de anemia en trabajadores de Siderperu. Población muestral: 50 trabajadores. Determinación de la plumbemia: Espectroscopia de absorción atómica con horno de grafito. Análisis de hemoglobina: colorimétrico para la determinación de hemoglobina como cianuro de hemiglobina en sangre. Resultados: En la correlación de los niveles de plumbemia y el tiempo de exposición de los trabajadores de Siderperu se muestra que no existe una correlación significativa entre la concentración de plomo en la sangre y el tiempo de exposición de los trabajadores. Respecto a la correlación de los niveles de plumbemia y el área de trabajo de los trabajadores el 34 % de la población de estudio labora en el área de proceso para barras mineras, el 18 % labora en el proceso para fierro de construcción, el 16 % en la planta de acero, el 14 % en talleres guiados, el 12 % en zona de estandarizado y el 6 % en bobinas de importación. El 6 % de los trabajadores tienen valores de plumbemia que requieren pasar por examen médico, todos ellos laboran en el área de proceso para barras mineras. No existe una correlación significativa entre la concentración de plomo en la sangre y la edad de los trabajadores. El 74 % de los trabajadores presentan anemia leve. Existe una correlación inversa altamente significativa entre la concentración de plomo en la sangre y la concentración de hemoglobina. Conclusiones: Se determinó que la relación entre la concentración de plomo en sangre y la concentración de hemoglobina de los trabajadores de SIDERPERÚ, fue significativa. Palabras clave: Plomo, Anemia, Plumbemia, Hemoglobina, Trabajadores. / --- Introduction: Lead inhibits heme synthesis and therefore hemoglobin. Objectives: To evaluate chronic lead poisoning and its relation to problems of anemia in workers SIDERPERU. Sample population: 50 employees. Determination of blood lead: Atomic absorption spectroscopy with graphite furnace. Hemoglobin analysis: for the colorimetric determination of hemoglobin as blood hemiglobin cyanide. Results: The correlation between blood lead levels and exposure time workers Siderperu shown that there is a significant correlation between the concentration of lead in the blood and the time of exposure of workers. Regarding the correlation of blood lead levels and the workspace of workers 34 % of the study population working in the area of process mining bars, 18 % work in the construction process for iron, 16 % in the steel plant, 14 % in workshops led, 12 % in area standardized and 6 % in coils import. 6 % of workers have blood lead values that require going through medical examination, all working in the area of process mining bars. There is no significant correlation between the concentration of lead in the blood and the age of the workers. 74 % of workers have mild anemia. There is a highly significant inverse correlation between the concentration of lead in the blood and hemoglobin concentration. Conclusions: We found that the relationship between blood lead concentration and hemoglobin concentration SIDERPERU workers, was significant. Keywords: Lead, Anemia, blood lead, hemoglobin, workers. / Tesis

Isso posto, o presente estudo tem por objetivo geral comparar o desempenho intelectual de crianças com alta e baixa plumbemia com os estilos parentais nas respectivas interações com os filhos. Para isso, foi utilizada a Escala Wechsler de Inteligência - WISC-III; Roteiro de Anammese e o IEP (Inventário de Estilos Parentais). Este estudo foi realizado com 80 participantes - 40 crianças, de ambos os sexos, com idades entre 7 e 13 anos; e 40 pais (pai e mãe), todos moradores da área de risco próximo ao local de contaminação. As crianças foram divididas em dois grupos: G1 - 20 crianças com alta plumbemia (superior a 10μg/dl); e G2 - 20 crianças com baixa plumbemia (inferior a 10μ/dl). Com as informações coletadas, procedeu-se a análise estatística com Teste do Mann Whitney, com 5% de significância. Os resultados foram apresentados de forma a contemplar cinco conjuntos de dados: I) Caracterização das crianças com alta plumbemia; II) Dados anamnésicos; III) WISC-III; IV) IEP - Inventário de Estilos Parentais e V) Comparação entre o WISC-III com o IEP. A análise dos dados apontou redução da plumbemia nas crianças entre os anos de 2002 e 2005. Para as crianças com alta plumbemia os pais relataram maior número de queixa escolar, problemas de saúde, socialização e motor, embora sem significância estatística entre os grupos. Nos itens avaliados pelo WISC-III, o desempenho do Grupo I foi menor que o do Grupo 2. Na Escala de Execução o desempenho dos dois grupos foi menor que para a escala Verbal, com diferença estatística entre os grupos em: QIE (0,001) e QIOP (0,04)... / The lead poisoning cause impairment to the children's development, being strenghten by other environmental and social variables, as inadequate feeding, poverty, low income and quality of the stimulation and interaction supplied by the parents and school. The aim of the present study is to evaluate the children's intellectual development with high and low blood lead level with the parenting styles in the respective interactions with these children. In order to accomplish this study were used - WISC-III; Anamnese's Script and IEP (Parenting Styles's Inventory), in which all of the 80 participants - 40 children, of both sexes, with ages among 7 to 13 years old, and 40 parents (father or mother), lived in the risk's area, next to the contamination place. The children were divided into two groups: G1-20 children with blood lead level above 10μg/dl; and G2 - 20 children with blood lead level lower than 10μg/dl. With the collected information, the statistical analysis was preceded with Mann Whitney's test, with 5%. The results were presented in way to contemplate five groups of data: I) the children's Characterization with plumbemia; II) Anamnese's Script Date; III) WISC-III; IV) IEP - Parenting Styles's Inventory I and V) Comparison between WISC-III IEP. The analyzed data's showed a reduction of the bllod lead level in children between 2002 and 2005. For the children blood lead level the parents related a larger number of school complaints, health problems, socialization and less motor development, although without statistical difference between the groups. In the items evaluated by WISC-III, the development of Group 1 was smaller than Group 2. In the Scale of Execution the development for both groups were lower than the Verbal Scale, with statistical difference between the groups in: QIE (0,001) and QIOP (0,04). In the Parenting Styles...
