“…Conservation practices that promote water infiltration on hillslopes avoid the product from reaching the floodplain area and water sources in low-lying areas. Atrazine was found in sediments across a riparian zone located in an area of silviculture (DREVENKAR et al, 2004). The authors concluded that the length of the slope an d veget a bl e cover a r e im por ta n t for contamination of this erosion sediment by this herbicide.…”

Atrazine is still being used in no-till corn production in Brazil. This herbicide can be moved by overland flow and leached in the soil profile. In both ways, it can pollute water, either by reaching the groundwater or lakes and streams close to the crop field. This study evaluated the presence of atrazine in a dystrophic Yellow-Red Argisol and a dystrophic Melanic Gleisol in a corn field, where atrazine has been applied for 11 years. Overland flow was the main process of atrazine transport on hillslope and leaching was the most important process in the floodplain. Frequency and location of atrazine application in the landscape define this herbicide contamination process.Index terms: Herbicide, overland flow, maize. RESUMOAtrazina ainda é empregada em áreas sob plantio direto para a produção de milho no Brasil. Esse herbicida pode ser transportado por escoamento superficial ou pela lixiviação no perfil do solo. De uma forma ou de outra, ele pode contaminar a água do subsolo ou de lagos e cursos d'agua próximos à área de plantio. Este estudo avaliou a presença de atrazina em um Argissolo Vermelho-Amarelo distrófico e em um Gleissolo Melânico distrófico em uma área de cultivo de milho, onde a atrazina tem sido utilizada há 11 anos. O escoamento superficial foi o principal processo de transporte de atrazina na encosta e a lixiviação foi o predominante na várzea. A frequência e a localização da aplicação de atrazina na paisagem definem o processo de contaminação deste herbicida.Termos para indexação: Herbicida, escoamento superficial, milho.

“…water intended for human consumption. The occurrence of herbicide residues and their degradation products in water resources as the result of their extensive use on agricultural and nonagricultural land has been recognised as a serious problem in different parts of the world (Garmouma et al 1997;Close and Flintoft 2004;Drevenkar et al 2004;Scribner et al 2004;Guzzella et al 2006;Konstantinou et al 2006;Na et al 2006;Tran et al 2007;Hladik et al 2008a;Hladik et al 2008b;Kumar and Xagoraraki 2010;Loos et al 2010;Bohn et al 2011;Segura et al 2011;Jin and Peldszus 2012;Aslam et al 2013;Bottoni et al 2013;Hermosin et al 2013;George 2014a, b;Papadakis et al 2015). Atrazine, one of the worlds' most heavily applied herbicides, is regularly found in ground (Close and Flintoft 2004;Scribner et al 2004;Tran et al 2007;Loos et al 2010;Aslamet al 2013) and drinkingwater, aswell asin coastalwaters (Nödler et al 2013) and in sea water and ice in remote areas (Chernyak et al 1996).…”

The frequency and mass concentrations of 13 herbicide micropollutants (triazines, phenylureas, chloroacetanilides and trifluralin) were investigated during 2014 in surface, ground and drinking waters in the area of the city of Zagreb and its suburbs. Herbicide compounds were accumulated from water by solid-phase extraction using either octadecylsilica or styrene-divinylbenzene sorbent cartridges and analysed either by high-performance liquid chromatography with UV-diode array detector or gas chromatography with mass spectrometric detection. Atrazine was the most frequently detected herbicide in drinking (84 % of samples) and ground (61 % of samples) waters in mass concentrations of 5 to 68 ng L. It was followed by metolachlor and terbuthylazine, the former being detected in 54 % of drinking (up to 15 ng L) and 23 % of ground (up to 100 ng L) waters, and the latter in 45 % of drinking (up to 20 ng L) and 26 % of ground (up to 25 ng L) water samples. Acetochlor was the fourth most abundant herbicide in drinking waters, detected in 32 % of samples. Its mass concentrations of 107 to 117 ng L in three tap water samples were the highest of all herbicides measured in the drinking waters. The most frequently (62 % of samples) and highly (up to 887 ng L) detected herbicide in surface waters was metolachlor, followed by terbuthylazine detected in 49 % of samples in mass concentrations of up to 690 ng L, and atrazine detected in 30 % of samples in mass concentrations of up to 18 ng L. The seasonal variations in herbicide concentrations in surface waters were observed for terbuthylazine, metolachlor, acetochlor, chlortoluron and isoproturon with the highest concentrations measured from April to August.

“…The mechanism of action of atrazine is inhibition of photosynthesis by blocking the electron transfer in photosystem II [2]. Atrazine is among the most widely applied herbicides in a number of countries and because of its widespread use, relatively high chemical and biological stability in soils and aquifers [3][4][5][6], and high leaching potential, has in several instances been reported to be present in surface and ground waters at alarmingly high concentration levels [7][8][9][10]. EU Directive 98/83/EC, on the quality of water intended for human consumption, has set the maximum concentration of atrazine to 0.1 µg/L and the total concentration of all pesticides to 0.5 µg/L.…”
