“…Depending on the physical and chemical characteristics, there is therefore the possibility of detection of this product in wells and water springs; Additionally, according to the water treatment system in cities, their detection is possible even in residential water samples (Lagana et al, 2002).…”

-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

“…MCPA, a systemic herbicide used for the post-emergence control of broad-leaf weeds (Tomlin, 1994), is such an example of an agricultural pesticide that is commonly found in waters and soil (Silva et al, 2006;Köck et al, 2010;Botta et al, 2012;Matamoros et al, 2012a). The risks of leaching from soil into ground and surface water are significant, due to the relatively high water solubility (825 mg L −1 ) and mobility, and a persistence in the environment of several weeks (Laganá et al, 2002;Cerejeira et al, 2003).…”

H I G H L I G H T S• CW with LECA substrate and Phragmites plants tested with agricultural wastewaters.• High removals of TSS, COD, NH 4 -N, polyphenols, a pharmaceutical and a pesticide.• Contact time of wastewaters with beds ranged from 3 to 9days in batch conditions.• Promising results suggest more studies in full-scale and more realistic conditions. Constructed wetlands (CWs) are receiving a renewed attention as a viable phytotechnology for treating agricultural wastewaters and for the removal of more specific pollutants, in particular recalcitrant ones. In this work, the performance of CW mesocosms using light expanded clay aggregates (LECA) as the bed's substrate and planted with Phragmites australis was investigated for treatment of olive mill wastewater (OMW), swine wastewater (SW) contaminated with oxytetracycline and water contaminated with herbicide MCPA (2-methyl-4-chlorophenoxyacetic acid). Both wastewaters (OMW and SW) initially presented high organic matter content and total suspended solids which were removed by the system with efficiencies higher than 80%. Removal of polyphenols in OMW and nitrogen compounds in SW also showed similar or higher efficiencies in comparison with other treatment systems reported in the literature. The antibiotic oxytetracycline was completely removed from SW within the assay period in unplanted LECA beds, but planted beds allowed a significantly faster removal. In regard to water contaminated with MCPA, the results showed that LECA has a large sorption capacity for this herbicide (removal efficiencies of 56-97%). In general, considerably higher pollutant removal efficiencies were obtained when plants were used (up to 28% higher). The results obtained are indicative that CWs with LECA as substrate may be an adequate option for agricultural wastewater treatment. a b s t r a c t a r t i c l e i n f o

“…The herbicide 2,4-D is also known to persist in the soil and contaminate surface and underlying groundwater. Even after a long period of use various amounts of 2,4-D were detected in surface water and ground water [3]. Hence the development of an effective degradation process for this herbicide has become a necessity.…”
