Resumo: | Introduction: Bromate is mutagenic and a probable carcinogen in humans. It usually does not occur in water for human consumption, but contamination can occur by industrial wastewater and in the disinfection process by ozonization (if bromide is present) or by the use of hypochlorite solution of unsatisfactory quality. Objective: Describe bromateconcentrations in the water supply of 89 municipalities in the state of São Paulo (Brazil), the physicochemical profiles of the waters in which the contaminant occurs, and a joint action between the Public Health Laboratory, the Sanitary Surveillance Regional Group and two Sanitary Surveillance of municipalities where important levels of bromate were found. Method: 4,853 samples were analyzed in 21 physicochemical parameters (including bromate concentration) and 2 microbiological parameters. For multivariate analysis, 4 demographic parameters were included. Results: Bromato was found in 224 samples (4.6% of the total) from 17 municipalities. The concentrations ranged between 3 and 199 μg L-1 and 56 samples (1.1% of the total) presented levels above the Maximum Allowed Value. Principal Component Analysis in these 17 municipalities indicated KBrO3 as the predominant form of contamination. The contamination rates of two municipalities decreased from the availability to the Sanitary Surveillance of reports that included bromate results. Conclusions: The data suggest that the monitoring of bromate concentrations should be included in the routine of the Water Surveillance Program for Human Consumption in the state of São Paulo. The notifications of the Sanitary Surveillance with those responsible for the water supply of two municipalities were important to improve the quality of the water supplied to the population in relation to contamination. |

Normalmente não ocorre em águas para consumo humano, mas a contaminação pode ocorrer por águas residuárias industriais e pela desinfecção por ozonização (se brometo estiver presente) ou pelo uso de solução de hipoclorito de qualidade insatisfatória. Objetivo:Descrever as concentrações de bromato nas águas de abastecimento de 89 municípios do estado de São Paulo (Brasil), os perfis físico-químicos das águas nas quais o contaminante ocorre e uma ação conjunta entre Laboratório de Saúde Pública, Grupo de Vigilância Sanitária e de duas Vigilâncias Sanitárias dos municípios onde foram encontrados níveisimportantes de bromato. Método: Foram analisadas 4.853 amostras em 21 parâmetros físico-químicos (incluindo concentração de bromato) e dois microbiológicos. Para análise multivariada foram incluídos quatro parâmetros demográficos. Resultados: O bromato foi encontrado em 224 amostras (4,6% do total) de 17 municípios. As concentrações variaram entre 3 e 199 μg L-1 e 56 amostras (1,1% do total) apresentaram teores acima do valor máximo permitido. A Análise de Componentes Principais nesses 17 municípios indicou KBrO3 como a forma predominante de contaminação. Os índices de contaminação de dois municípios diminuíram a partir da disponibilização para as Vigilâncias Sanitárias de laudos que incluíram os resultados de bromato. Conclusões: Os dados sugerem que o monitoramento das concentrações de bromato deveria ser incluído na rotina do Programa de Vigilância da Água para Consumo Humano do estado de São Paulo. As notificações das Vigilâncias Sanitárias junto aos responsáveis pelo abastecimento de água de dois municípios foram importantes para a melhoria da qualidade da água fornecida à população em relação à contaminação.Instituto Nacional de Controle de Qualidade em Saúde2022-05-31info: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/201510.22239/2317-269x.02015Health Surveillance under Debate: Society, Science & Technology ; Vol. 10 No. 2 (2022): May; 68-76Vigilancia en Salud en Debate: Sociedad, Ciencia y Tecnología; Vol. 10 Núm. 2 (2022): Puede; 68-76Vigil Sanit Debate, Rio de Janeiro; v. 10 n. 2 (2022): Maio; 68-762317-269Xreponame:Vigilância Sanitária em Debateinstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZporenghttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/2015/1401https://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/2015/1432Copyright (c) 2022 Vigilância Sanitária em Debate: Sociedade, Ciência & Tecnologiahttps://creativecommons.org/licenses/by-nc/4.0/info:eu-repo/semantics/openAccessDovidauskas, SergioAkemi Okada, IsauraRodrigues dos Santos, FelipeMiyuki Okada, Marinade Cássia Briganti, RitaAntonio Moreira Souto, Marco2023-06-27T15:14:22Zoai:ojs.visaemdebate.incqs.fiocruz.br:article/2015Revistahttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebatePUBhttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/oaiincqs.visaemdebate@fiocruz.br || gisele.neves@fiocruz.br2317-269X2317-269Xopendoar:2023-06-27T15:14:22Vigilância Sanitária em Debate - Fundação Oswaldo Cruz (FIOCRUZ)false |
