“…The latter study showed that the seasonal load mitigation of runoff-related fungicides through the stormwater wetland is 75%. Further estimates of this relationship were based on recent and related studies that emphasize the relationship between wetland size and pesticide mitigation of the wetland (Lange et al, 2010;Stehle et al, 2011). The extension of the wetland's surface area is expected to enhance the capacity of fungicide mitigation for an equivalent fungicide load, since the sorption surface (plant and wetland sediment) and the water surface, both subject to UV light and thus to fungicide photolysis, are expected to increase proportionally.…”

“…Recently, UR was applied as a reference substance to mimic photolytic decay of a contaminant (e.g. pesticide) in surface waters (Lange et al, 2011). UR has also widely been used in industry and health care applications, mainly because of its bright green color, high water solubility, moderately low costs and low toxicity (Ikeya et al, 2009;Jean et al, 2007;Smart and Laidlaw, 1977).…”

“…O traçador também deve ser não reativo e passível de ser injetado em curto período de tempo (METCALF & EDDY, 2003;BORGES, et al, 2009;SILVA et al, 2009). O cloreto de sódio, por exemplo, é de fácil aquisição, baixo custo e de fácil detecção (COTA et al, 2011) ; no entanto, apresenta características que o tornam não ideal, como ser passível de absorção; suas soluções não apresentarem massa específica semelhante à do líquido em tratamento, o que pode ocasionar fluxo preferencialmente vertical do sal, especialmente quando utilizadas soluções mais concentradas (LANGE et al, 2011). Como sua concentração é relativamente alta no esgoto sanitário bruto, cerca de 150 mg L -1 de NaCl (PRATA et al, 2013), torna-se necessária a utilização de soluções traçadoras com maiores concentrações desse sal, o que pode concorrer para o aumento no tempo de permanência do traçador e a salinização do sistema (COTA et al, 2011).…”
