“…In over 60% of water samples was the herbicide detected in all collecting seasons (Table 4) and at depths up to 160 m. This herbicide has been used for striking weed management in the current sugarcane cultivation system, mainly due to its efficacy (Carbonari et al, 2010). According to Santos et al (2013), clomazone has a high groundwater contamination potential, because of its high solubility in water (1.1 L -1 ) and a Koc of 300 mL g -1 .…”

-Due to the large amount of pesticides applied in agriculture, mainly herbicides, there is a growing concern about a possible environmental contamination with these products, including water bodies. Given the above, the aim of the present work was to detect and quantify herbicides through multiresidue analysis in water samples collected in semiartesian wells and springs in a rural area of the city of Jaboticabal (SP). Samples were collected from 32 wells and 13 water springs, in three different seasons: October 2010, February 2011 and May 2011. Additionally, samples at a residence in the urban area were also collected. Analysis using high performance liquid chromatography coupled to mass spectrometry was performed and herbicides ametryn, amicarbazone, clomazone, diclosulan, diuron, hexazinone, imazapic, imazapyr, isoxaflutole, S-metolachlor, sulfentrazone, sulfometuron-methyl, and tebuthiuron were evaluated. In semi-artesian wells, an incresed quantity of herbicides was found in comparison with the water springs. Among the tested herbicides, hexazinone, imazapyr and sulfentrazone were detected in measurable amounts in accordance with the analytical method applied, while clomazone was the most common herbicide being detected in more than 60% of the samples. Ametryn, diuron and amicarbazone herbicides were also detected. Diclosulan, imazapic, isoxaflutole, S-metolachlor, sulfometuron-methyl, and tebuthiuron were not detected in any sample. Inappropriate use of these products without prior knowledge of the behavior of the soil can lead to groundwaters and water springs contamination, thus an ongoing monitoring of this resource becomes very important.Keywords: sugarcane, LC-MS/MS, water springs, semi-artesian wells. ametryn, amicarbazone, clomazone, diclosulan, diuron, hexazinone, imazapic, imazapyr, isoxaflutole, S-metolachlor, sulfentrazone, sulfometuron-methyl SANTOS, E.A. et al. RESUMO -Em vista da grande quantidade de agroquímicos aplicados na agricultura, principalmente os herbicidas, cresce a preocupação com a possível contaminação do ambiente com esses produtos, inclusive em corpos d'água. Diante do exposto, o objetivo deste trabalho foi detectar e quantificar herbicidas, por meio de análise multirresíduo, em amostras de água coletadas em poços semiartesianos e nascentes, em uma área rural da cidade de Jaboticabal (SP). Foram coletadas amostras em 32 poços e 13 nascentes, em três épocas: outubro de 2010, fevereiro e maio de 2011. Foram coletadas, adicionalmente, amostras em uma residência na área urbana. Foi realizada análise por cromatografia líquida de alta eficiência acoplada à espectrometria de massas e foram avaliados os herbicidas

“…al., 2008). Portanto, grandes quantidades deste resíduo ficam disponíveis sobre o solo da área, provocando mudanças nas práticas de manejo dos canaviais, seja no trânsito de maquinário (MICHELAZZO; BRAUNBECK, 2008), na fertilização do solo (SPAROVEK;SCHNUG, 2001), no controle de plantas infestantes e uso de pesticidas (CARBONARI et. al., 2010a;DURIGAN, 2004;ROSSI et.…”
