Diffuse pollution of agricultural areas has seriously compromised the quality of water resources. Aroundthe world, peatlands are environments located on the slope lower third, which receive all the runoff andpollutants carried by agricultural areas. We evaluate the behavior of pesticides in peatlands as a naturaltool to reduction nonpoint pollution from no-till system. This study was conducted in two steps in apeatland (6 ha) subdivided into three transects. The first step, it was performed a pesticides monitoringfrom agricultural areas (no-till system). On second step, the pesticide lambda cyhalothrin was applied onexperimental plots. The water sampling was performed with the aid of monitoring wells (0?30, 30?60 and60?90 cm depth), and the removed made with a vacuum pump. Soil sampling was performed introducedPVC pipe diameter of 50 mm at the same depth that water samples. To the first step, the results wereas follow: To soil sample, a total of 52 detections were obtained, which are shown in order of relevancefor atrazine (32%) chlorpyrifos (27%) lambda-cyhalothrin (19%), fluazifop-p-butyl (11.5%) and lactofen(9%). As for the water samples, 32 results (detections) were performing, atrazine (37%) chlorpyrifos (32%)lambda-cyhalothrin (12.5%) and the fluazifop-p-butyl pesticides (9%) and lactofen (9%) of equal impor-tance. Spatially transect 1 was significantly different from transect 3 for all pesticides studied. The secondstep showed a significant reduction in the concentration of the pesticide lambda cyhalothrin over timeand increasing soil depth. The highest concentration in the samples was at a depth of 0?30 cm, wherethe organic carbon content was higher.
