Resumo: | The aim of the present study was to analyze the mercury content in fish commercialized in Minas Gerais, collected by the Food Monitoring Program of the Health Surveillance of Minas Gerais - PROGVISA, and to verify, based on these values, the risk of fish consumption. The total mercury content in 80 fish samples randomly collected from the Minas Gerais market was analyzed. The analyses were performed by atomic absorption spectrometry with gold amalgamation. From these values, the intake of methylmercury in Minas Gerais was estimated and it was compared with the toxicological reference parameters. Among the samples, 38.8% were from non-predatory fish and 61.2% were from predatory fish. The results indicated that the mercury levels found in most fish samples from Minas Gerais were below the maximum limits allowed by Brazilian legislation. Only 8.2% of the samples of predatory fish showed unsatisfactory results (contents> 1.0 mg / kg), only shark, in this case. In general, non-predatory fish and usually aquaculture fish, such as Tilapia, Panga and Salmon, had low mercury levels. The estimated mercury intake for the population of Minas Gerais was considered acceptable, without appreciable risk to health. Fish consumption following the recommendation of two to three servings per week, excluding fish at the top of the food chain, appears to be safe. The results indicate that mercury contents below the limits established by the Brazilian legislation are important to guarantee intake of this contaminant at safe levels. |

Se analizó el contenido total de mercurio en 80 muestras de peces recolectados al azar en el mercado de Minas Gerais. El análisis se realizaron por espectrofotometría de absorción atómica. A partir de estos valores, se estimó la ingesta de metilmercurio en Minas Gerais y esta estimación se comparó con los parámetros toxicológicos de referencia. Entre las muestras, 38.8% eran de peces no depredadores y 61.2% eran de peces depredadores. Los análisis indicaron que los niveles de mercurio encontrados en la mayoría de las muestras de peces de Minas Gerais estaban por debajo de los límites máximos permitidos por la legislación brasileña. Solo el 8.2% de las muestras de peces depredadores mostraron resultados no satisfactorio (contenido> 1.0 mg / kg), siendo solo los peces catiónicos. En general, los peces no depredadores y, por lo general, los peces de acuicultura, como la tilapia, el panga y el salmón, tenían niveles bajos de mercurio. La ingesta de mercúrio, estimada para la población de Minas Gerais se consideró aceptable, sin un riesgo apreciable para la salud. El consumo de pescado, siguiendo la recomendación de dos o tres porciones por semana, siempre y cuando el pescado en la parte superior de la cadena alimentaria no esté incluido, parece ser seguro. Los resultados indican que el contenido de mercúrio, por debajo de los límites establecidos por la legislación brasileña, son importantes para garantizar la ingesta de este contaminante a niveles seguros.O objetivo do trabalho foi analisar o teor de mercúrio em peixes comercializados em Minas Gerais, coletados pelo Programa de Monitoramento de Alimentos da Vigilância Sanitária de Minas Gerais - PROGVISA, e verificar com base nesses valores o risco do consumo de peixes. Foi analisado o teor de mercúrio total em 80 amostras de peixes coletadas de forma aleatória no mercado de Minas Gerais. As análises foram feitas por espectrofotometria de absorção atômica após amalgamação em ouro. A partir desses valores foi estimada a ingestão de metilmercúrio em Minas Gerais e esta estimativa foi comparada com parâmetros toxicológicos de referência. Dentre as amostras, 38,8% eram de peixes não predadores e 61,2% eram de peixes predadores. Os resultados indicaram que os teores de mercúrio encontrados na maioria das amostras de peixes de Minas Gerais foram inferiores aos limites máximos permitidos pela legislação brasileira. Somente 8,2% das amostras de peixes predadores apresentaram resultados insatisfatórios (teores >1,0 mg/kg), sendo somente o peixe cação. Em geral, peixes não predadores e peixes usualmente de aquicultura, como tilápia, panga e salmão, apresentaram teores de mercúrio baixos. A ingestão de mercúrio estimada para a população de Minas Gerais foi considerada aceitável, sem risco apreciável à saúde. O consumo de peixes seguindo a recomendação de duas a três porções semanais, desde que não se inclua peixes do topo da cadeia alimentar, parece ser seguro. Os resultados indicam que teores de mercúrio abaixo dos limites estabelecidos pela legislação brasileira são importantes para garantir ingestões desse contaminante em níveis seguros.Research, Society and Development2020-08-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/688110.33448/rsd-v9i9.6881Research, Society and Development; Vol. 9 No. 9; e105996881Research, Society and Development; Vol. 9 Núm. 9; e105996881Research, Society and Development; v. 9 n. 9; e1059968812525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/6881/6230Copyright (c) 2020 Ághata de França Costa, Flávia Beatriz Custódio, Nilton de Oliveira Couto e Silva, Renata Adriana Labancahttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCosta, Ághata de FrançaCustódio, Flávia BeatrizSilva, Nilton de Oliveira Couto eLabanca, Renata Adriana2020-09-18T01:42:11Zoai:ojs.pkp.sfu.ca:article/6881Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:50.061411Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
