“…van Noordwijk et al, 1991;Schwartz et al, 1998;Reichenberger et al, 2002;Ciglasch et al, 2005), do not have extensive soil piping. Alternatively, the limited number of published studies may result from a wider dearth of research on runoff processes within the humid tropics and the difficulty of observing pipe outlets and depression lines within the region's dense rainforest cover.…”

“…These macropores in the soil form preferential pathways causing solutes such as pesticides to move with the infiltrating water without interacting with the soil in a process known as preferential flow. 36 This process was also detected in a nearby region by Reichenberger et al 37 Another fact that may have contributed to the frequent detection of endosulfan sulfate on groundwater is the intensive use of its parental compound endosulfan. Although the farmers did not inform the applied pesticides, it is known, from previous studies, 9,21 that in the Mato Grosso cotton plantation, endosulfan may be applied up to seven times during a crop period.…”

“…This is due to its intensive use and to preferential flow that is common in this region soil. 37 Endosulfan, atrazine, metolachlor and flutriafol were also detected in rainwater. Some properties of the pesticides and environment can explain the presence of these substances in rainwater.…”

“…O comportamento também pode ser explicado pelo fato de não haver uma correlação diretamente proporcional nos valores de porosidade e permeabilidade no presente estudo. Esse comportamento foi observado no estudo do deslocamento de pesticidas em um Latossolo (Oxisol) na cidade de Cuiabá (MT), em que o principal determinante na lixiviação foi o fluxo preferencial e não o efeito da porosidade ou da estrutura dos agregados (Reichenberger et al, 2002).…”
