Resumo: | The Brazilian agricultural model is based on the intensive use of pesticides. Once in the environment, these compounds might target hydric sources, mainly through soil lixiviation or during crop application, exposing water biota as well as humans to contaminants. The objective of this research was identify the presence of 14 pesticides (ametrine, atrazine, azoxystrobin, carbendazim, carbofuran, clomazone, chlorpirifos, diuron, hexazinone, imidacloprid, malathion, simazine, tebuconazole and tebuthiuron) in source water samples and drinking water samples from the city of Londrina, Paraná State, Brazil. 24 water samples were collected biweekly from December 2014 to October 2015. The sample preparation was done using Solid Phase Extraction (SPE) with 3 mL/500 mg C-18 cartridges. Pesticide determination was performed applying Liquid Chromatography tandem Mass Spectrometry (LC-MS/MS). The frequencies of detection of some compounds in source water were: atrazine (85%), azoxystrobin (95%), carbendazim (83%), diuron (75%), imidacloprid (95%), simazine (12%), hexazinone (4%), tebutiuron (4%) and tebuconazole (33%). In the water supply, the following were detected: atrazine (79%), azoxystrobin (95%), carbendazim (8%), diuron (83%), imidacloprid (95%), simazine (12%), hexazinone (4%), tebuthiuron (8%) and tebuconazole (33%). Some of these compounds are included in Brazilian legislation, and in these cases, the concentrations determined in this study varied between 241 and 7 ng L?¹, which were lower than the maximum allowable concentrations for each of the compounds. |

Uma vez no ambiente, estes compostos podem atingir recursos hídricos, principalmente através da lixiviação ou durante a aplicação, expondo a biota aquática e até mesmo humanos, aos contaminantes. O objetivo deste trabalho foi identificar a presença dos agrotóxicos ametrina, atrazina, azoxistrobina, carbendazim, carbofurano, clomazona, clorpirifós, diuron, hexazinona, imidacloprido, malation, simazina, tebuconazol e tebutiuron em amostras de água de manancial e de abastecimento público da cidade de Londrina, Paraná, Brasil. Foram coletadas 24 amostras, quinzenalmente, de Dezembro de 2014 a Outubro de 2015. Para o preparo das amostras foi utilizado Extração em Fase Sólida (SPE) com cartuchos de 3 mL C-18 de 500 mg. A determinação de agrotóxicos foi realizada utilizando Cromatografia Líquida acoplada à Espectrometria de Massas (LC-MS/MS). Nas amostras do manancial, foram detectados os compostos atrazina (85%), azoxistrobina (95%), carbendazin (83%), diuron (75%), imidacloprido (95%), simazina (12%), hexazinona (4%), tebutiuron (8%) e tebuconazol (33%). Nas amostras de água para abastecimento público, foram detectados atrazina (79%), azoxistrobina (95%), carbendazim (8%), diuron (83%), imidacloprido (95%), simazina (12%), hexazinona (4%), tebutiuron (8%) e tebuconazol (33%). Alguns destes compostos estão inseridos na legislação brasileira e nestes casos, as concentrações determinadas neste estudo variaram entre 241 e 7 ng L-1, as quais foram inferiores às máximas concentrações determinadas para cada um dos compostos.UEL2019-05-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3311310.5433/1679-0359.2019v40n3p1153Semina: Ciências Agrárias; Vol. 40 No. 3 (2019); 1153-1164Semina: Ciências Agrárias; v. 40 n. 3 (2019); 1153-11641679-03591676-546Xreponame:Semina.
