“…This is in agreement with the conclusions of other recent European studies (Kay et al, 2009;Stehle et al, 2011;Maillard et al, 2011). Comparison with results from other research is possible only after a clear and simple definition of mitigation or removal, as proposed in this study.…”

“…Kay et al (2009) reported that for a constructed wetland, the average reduction in pesticide mass loss was 80% and varied from 25 to 100%. In a recent review, Stehle et al (2011) found that the majority of constructed wetlands retained at least 70% of the entering pesticides, while for Maillard et al (2011) removal rates varied from 39 to 100%.…”

Mitigation of herbicide runoff as an ecosystem service from a constructed surface flow wetland

Ecosystem services provided by wetland\ud systems presently play a pivotal role in intensive\ud cropland as water purification from agricultural pollution.\ud A field trial was conducted in 2014 to evaluate\ud herbicide runoff reduction and retention using a\ud 0.32 ha constructed surface flow wetland (CSFW) at\ud the outlet of a 6 ha agricultural basin. To simulate an\ud extreme pulse contamination, the CSFW was flooded\ud with a runoff contaminated with metolachlor, and\ud terbuthylazine and two other subsequent floods with\ud pure water were applied 21 and 65 days later. Results\ud show that the CSFW can reduce runoff concentration\ud of metolachlor and terbuthylazine by a factor of 45–80\ud even in extreme flooding conditions. Herbicides\ud retention in the CSFW was reversible, and the second\ud and third floods mobilized 14–31 and 3.5–7.0%\ud respectively, of the amount detected in the first flood.\ud The CSFW performs a high buffer capacity for\ud herbicides, capable to provide water purification\ud service, protecting downstream surface water. Moreover,\ud mitigation capacity of a CSFW for a heavy\ud runoff from a 10 ha basin is 90% for every 50 m in\ud length of a 15 m wide wetland. This confirms that the\ud implementation of CSFWs in agro-systems can\ud improve the sustainability of agricultural production

“…En Suráfrica, se hizo una evaluación a un humedal construido para controlar la contaminación no puntual por pesticidas, y se halló que ninguno de los compuestos analizados fueron detectados a la salida, bajo diferentes condiciones climáticas [24], situación parecida en un campo de golf en la India [84], y en diferentes humedales en Francia, donde se alcanzaron remociones del 100% para diferentes estaciones del año [85].…”

RESUMENLa concentración de contaminantes en aguas lluvia es un tema que preocupa a las entidades gubernamentales porque deterioran la calidad hídrica de las fuentes receptoras. En varios países, se han iniciado investigaciones y desarrollo de metodologías para tratar este tipo de aguas. Una de estas técnicas es la ejecución de humedales artificiales, y es una de las más aceptadas por su gran eficiencia en la remoción de contaminantes. El presente artículo expondrá el estado del conocimiento, estudiando los métodos de diseño, eficiencias y las nuevas tendencias en la investigación de humedales artificiales que tratan aguas lluvia y/o escorrentía urbana.Palabras clave: contaminación de aguas lluvias, fuentes difusas, fuentes puntuales, humedales artificiales, mejores prácticas de manejo (BMP), tratamiento de aguas lluvias. ABSTRACTThe pollutant concentration of rainwater is a critical issue for government agencies since impairs the water quality at receiving sources. Some countries have begun research and developed systems for treatment of those waters where made wetland is the most common structure used. This paper offers a review of made wetland to runoff treatment, including design, effectiveness and new trends to research of made wetlands to treat rainwater and/or urban runoff.

A B S T R A C TThe objective of this study was to evaluate the remediation of water containing the insecticide chlorpyrifos by using constructed wetlands (CW) cultivated with Polygonum punctatum, Cynodon spp. and Mentha aquatica, operated under different hydraulic retention times: 24, 48, 96, 144 and 192 h. The system efficiency was based on reduction of the initial concentration of chlorpyrifos and toxicity of the contaminated water. The results showed that constructed wetlands are an excellent alternative for remediation of the insecticide chlorpyrifos in aqueous medium. It was observed that the average overall removal efficiency of the insecticide was 98.6%, and in the first hydraulic retention time, 24 h, chlorpyrifos was removed to levels below the detection limit in all CW. This result is mainly attributed to adsorption and microbial degradation. For the qualitative standard acute toxicity tests with Daphnia similis, for most samples there was a reduction in toxicity greater than 80%. It was reported that the ecotoxicological tests with the effluents of the constructed wetland are a good option as an indicator of the effectiveness of treatments and a promising alternative to complement the physical and chemical analyses.Remoção do inseticida clorpirifós em sistemas alagados construídos cultivados com diferentes espécies vegetais R E S U M O Objetivou-se neste trabalho avaliar a remediação de água contendo o inseticida clorpirifós, por meio de sistemas alagados construídos (SAC) cultivados com as espécies Polygonum punctatum, Cynodon spp. e Mentha aquatica operados sob diferentes tempos de retenção hidráulica: 24, 48, 96, 144 e 192 h. A eficiência do sistema foi baseada na redução da concentração inicial do clorpirifós e toxicidade da água contaminada. Os resultados mostraram que os sistemas alagados construídos são uma excelente alternativa na biorremediação do inseticida clorpirifós no meio aquoso. Observou-se média geral de eficiência na remoção do inseticida de 98,6%, sendo que no primeiro tempo de retenção hidráulica, 24 h, houve remoção do clorpirifós para valores inferiores ao limite detecção para todos os SAC. Tal resultado é atribuído principalmente aos processos de adsorção e degradação microbiana. Para os ensaios padronizados qualitativos de toxicidade aguda com Daphnia similis, para a maioria das amostras observou-se a redução de toxicidade acima de 80%. Constatou-se que os testes ecotoxicológicos com os efluentes dos sistemas alagados construídos estudados são uma boa opção como indicativo da eficiência dos tratamentos e uma promissora alternativa na complementação de análises físicas e químicas.
