“…Glyphosate residues have been found in surface waters (Dores & Freire, 2001;Silva et al, 2003;Queiroz et al, 2011), in groundwater (Sakaliene et al, 2007;Andrade et al, 2011;Britto et al, 2011), and in soil Souza et al, 2006).…”

“…Despite the higher variation amplitude according to the environmental conditions, the half-life of chlorpyrifos on average is 50 day in water, according with the literature (Dores & De-Lamonica-Freire, 2001). As mentioned previously, in less than 24 h the constructed wetland resulted in 99% removal of chlorpyrifos from the aqueous medium, indicating the potential of these systems their benefits when used, for example, to treat runoff water from agricultural areas.…”

“…Chlorpyrifos distribution among water and biofilm is a complex process affected by pesticide physico-chemical characteristics. The water solubility, soil organic carbon-water partitioning coefficient (K oc ) and octanol/water partition coefficient (K ow ) of chlorpyrifos are 1.4 mg L -1 , 4.7 (log) and 4981 cm 3 g -1 respectively (Dores & De-Lamonica-Freire, 2001). Such characteristics make the organophosphate chlorpyrifos a pesticide with high retention in the constructed wetlands, as suggested by Vymazal & Březinová (2015), that pesticides with high K oc value (log K oc > 3.0) has high removal in CW.…”

“…A concentração da maioria dos pesticidas nas águas é baixa, em parte devido ao fato de serem pouco solúveis em água e ao efeito da diluição (Dores & Freire, 2001). No entanto, não exclui a possibilidade de que concentrações muito altas venham a ocorrer depois de pesadas chuvas, principalmente quando áreas próximas tenham sido recentemente tratadas com altas doses dos pesticidas (Dores & Lamonica, 2001).…”
