Resumo: | Introduction: Water is a natural resource of vital importance to all living beings, but when it is polluted it can be the cause of various diseases. A wide variety of pollutants have been found in groundwater and nitrate is the most frequent pollutant. Objective: The objective of this work was to determine nitrate concentration in well water samples from public supply systems and collective alternative solutions from 22 municipalities in the Marília and Assis-São Paulo regions. Method: A total of 157 water samples from wells registered in municipal health surveillance were collected and the analyses were performed by spectrophotometric method in the UV region, according to physical-chemical methods for food analysis of the Adolfo Lutz Institute. Results: From the total of 157 samples analyzed, 141 samples (89.8%) were in agreement and 16 samples (10.2%) were in disagreement with the current legislation. Conclusions: It is concluded with the results of this study that the nitrate analysis is extremely important to evaluate the risks to human health andenvironment. It is suggested the annual monitoring of the wells that presented nitrate concentrations between 5 and 10 mg/L and the promotion of public policies that guarantee the population access to water in accordance with current legal standards. |

Uma grande variedade de substâncias contaminantes tem sido encontrada nas águas subterrâneas e o nitrato é o poluente de ocorrência mais frequente. Objetivo: O objetivo deste trabalho foi determinar a concentração de nitrato em amostras de água de poços de sistemas de abastecimento público e soluções alternativas coletivas de 22 municípios das regiões e Marília e Assis, São Paulo. Método: Foram coletadas 157 amostras de água de poços cadastrados nas Vigilâncias Sanitárias municipais e as análises foram realizadas pelo método espectrofotométrico na região Ultravioleta (UV), segundo métodos físicoquímicos para análise de alimentos do Instituto Adolfo Lutz. Resultados: Do total de 157 amostras analisadas, estavam de acordo com a legislação vigente 141 amostras (89,8%) e em desacordo 16 amostras (10,2%). Conclusões: Conclui-se, com os resultados deste estudo, que a análise de nitrato é de extrema importância para avaliar os riscos à saúde humana e ao ambiente. Sugere-se o monitoramento anual dos poços que apresentaram concentrações de nitrato entre 5 e 10 mg/L e a promoção de políticas públicas que garantam à população o acesso à água em conformidade com os padrões legais vigentes.Instituto Nacional de Controle de Qualidade em Saúde2019-05-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion"Peer-reviewed article""Artículo revisado por pares""Artigo avaliado pelos pares"application/pdfapplication/pdfhttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/129010.22239/2317-269x.01290Health Surveillance under Debate: Society, Science & Technology ; Vol. 7 No. 2 (2019): May; 102-106Vigilancia en Salud en Debate: Sociedad, Ciencia y Tecnología; Vol. 7 Núm. 2 (2019): Puede; 102-106Vigil Sanit Debate, Rio de Janeiro; v. 7 n. 2 (2019): Maio; 102-1062317-269Xreponame:Vigilância Sanitária em Debateinstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZporenghttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/1290/1019https://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/1290/1111Copyright (c) 2019 Vigilância Sanitária em Debate: Sociedade, Ciência & Tecnologia (Health Surveillance under Debate: Society, Science & Technology) – Visa em Debatehttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSilva, Rosângela Aguilar daSantos, Roberto CostaFerreira, Luci Ochi2023-06-27T15:11:12Zoai:ojs.visaemdebate.incqs.fiocruz.br:article/1290Revistahttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebatePUBhttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/oaiincqs.visaemdebate@fiocruz.br || gisele.neves@fiocruz.br2317-269X2317-269Xopendoar:2023-06-27T15:11:12Vigilância Sanitária em Debate - Fundação Oswaldo Cruz (FIOCRUZ)false |
