Resumo: | Introduction: The use of herbicides in different crops may leave residues, which can compromise the safety of the people who consume the derived products, as well of those environmentally and/or occupationally exposed. Paraquat is an herbicide of the bipyridyl class and it is used in diverse types of food culture besides the planting of tobacco. Objective: The objective of this work is to determine, by quantitative methods, the presence of Paraquat in tobacco samples in cigarettes from four high consumption brands. Method: A method was utilized to detect Paraquat waste by means of a colorimetric technique, since this active ingredient is reduced to a blue colored radical in the presence of 1% sodium dithionite (Na2S2O4) in basic medium, which intensifies as much as the concentration of the product increases. The samples were subjected to spectrophotometer reading (600 nm) and compared with a standard. Results: The quantitative evaluation revealed residual levels of the herbicide in all samples analyzed. Conclusions: There is a potential for toxicity in the use of Paraquate in the population. |

O paraquate é herbicida da classe dos bipiridílicos utilizado em diversos tipos de cultura de alimentos, além do plantio de fumo. Objetivo: Determinar, por método quantitativo, a presença de paraquate em amostras de tabaco em cigarros de quatro marcas de grande consumo. Método: Foi utilizado método para detectar resíduos de paraquate por meio de técnica colorimétrica, visto que este ativo é reduzido a radical de cor azul na presença de ditionito de sódio (Na2S2O4) a 1%, em meio básico, que se intensifica à medida que a concentração do produto aumenta. As amostras foram submetidas à leitura em espectrofotômetro (600 nm) e comparadas com um padrão. Resultados: A avaliação quantitativa revelou níveis residuais do herbicida em todas as amostras analisadas. Conclusões: Há potencial de toxicidade no uso do paraquate na população.Instituto Nacional de Controle de Qualidade em Saúde2017-11-30info: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/94810.22239/2317-269X.00948Health Surveillance under Debate: Society, Science & Technology ; Vol. 5 No. 4 (2017): November; 68-72Vigilancia en Salud en Debate: Sociedad, Ciencia y Tecnología; Vol. 5 Núm. 4 (2017): Noviembre; 68-72Vigil Sanit Debate, Rio de Janeiro; v. 5 n. 4 (2017): Novembro; 68-722317-269Xreponame:Vigilância Sanitária em Debateinstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZporenghttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/948/418https://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/948/486Copyright (c) 2017 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/openAccessFukushima, André RinaldiNicoletti, Maria AparecidaSantos, Fernanda Ferreira dosSilva, Juliana Sanchez daPereira, Vitor de OliveiraPonce, Fernando2023-06-27T15:01:00Zoai:ojs.visaemdebate.incqs.fiocruz.br:article/948Revistahttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebatePUBhttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/oaiincqs.visaemdebate@fiocruz.br || gisele.neves@fiocruz.br2317-269X2317-269Xopendoar:2023-06-27T15:01Vigilância Sanitária em Debate - Fundação Oswaldo Cruz (FIOCRUZ)false |
