“…A Fenton-like system using cobaltperoximonosulfate was effective to remove atra-zine under solar irradiation (Bandala et al, 2007). Fenton and the Fenton-like system Fe 0 /H2O2/H2SO4 were also effective on the removal of this herbicide, leading to toxicologically inactive small organic mole-cules or even to mineralization (Mackul'ak et al, 2011). Table S2 describes some electro-Fenton-based processes applied to the degradation of PFOS and some pesticides listed in the priority sub-stances of the Directive 2013/39/EU, namely the triazine pesticide atra-zine, the phenylurea pesticide diuron and the organophosphorus pentachlorophenol, all of them tested at mg L −1 levels.…”

“…3). Although atrazine has been banned in the European Union due to the widespread contamination of drinking water supplies, this pesticide considered an EDC, is still used in other regions of the world and for this reason is widely studied (Mackul'ak et al, 2011). Table S1 shows that atrazine was poorly degraded with UV/H2O2 using pre-treated water spiked with a set of 15 compounds at 10 μg L −1 each, while the conversion of all other tested compounds was higher (LekkerkerkerTeunissen et al, 2013).…”

Environmental pollution is a recognized issue of major concern since a wide range of contaminants has been found in aquatic environment at ng L −1 to μg L −1 levels.In the year 2000, a strategy was defined to identify the priority substances concerning aquatic ecosystems, followed by the definition of environmental quality standards (EQS) in 2008. Recently it was launched the Directive 2013/39/EU that updates the water framework policy highlighting the need to develop new water treatment technologies to deal with such problem. This review summarizes the data published in the last decade regarding the application of advanced oxidation processes (AOPs) to treat priority compounds and certain other pollutants defined in this Directive, excluding the inorganic species (cadmium, lead, mercury, nickel and their derivatives).The Directive 2013/39/EU includes several pesticides

“…47 50 A aplicação de processos Fenton na remoção de herbicidas e outras substâncias usadas no controle de pragas ambientais já foi amplamente relatada na literatura. [51][52][53][54] No caso dos herbicidas, a maior ocorrência e acumulação se dão em solos, pois estas substâncias são altamente lipofílicas. No entanto, a lixiviação do solo por água de chuva, marés, ou ainda, mudança no leito de rios, pode provocar o arraste dos herbicidas para os compartimentos aquáticos, o que levaria à contaminação dos mesmos e a necessidade de remoção dos herbicidas de ambientes aquáticos.…”

Fenton Processes as an Alternative to the Removal of Endocrine Disruptors and other Environmental PollutantsAbstract: Technological advances, combined to high levels of consumption by the population, led to an increase in the generation of waste, which compromise the availability of natural resources, especially water resources. Furthermore, sensitive analytical detections have increased the detection of environmental micropollutants, many highly toxic. Therefore, the search for alternatives to the removal of micropollutants from water is necessary to overcome the methods currently available. Advanced oxidative processes are efficient for the removal of micropollutants. This review summarizes the main aspects of environmental contamination by endocrine disruptors and the use of Fenton reactions as advanced oxidation processes in the removal of these micropollutants.Keywords: Advance oxidation processes; water resource; endocrine disruptor. ResumoO avanço tecnológico, associado aos altos níveis de consumo pela população, levou a um aumento na geração de resíduos ambientais que comprometem a disponibilidade de recursos naturais, principalmente de recursos hídricos. Associado a isto, o desenvolvimento de estratégias mais sensíveis de detecção analítica ocasionou um aumento na detecção de micropoluentes ambientais, muitos deles altamente tóxicos. Neste contexto, a busca por alternativas de remoção destes micropoluentes aquáticos se faz necessária, de maneira a ultrapassar a fronteira dos métodos de remoção atualmente disponíveis. Os processos oxidativos avançados são, reconhecidamente, alternativas eficientes para a remoção de micropoluentes ambientais. Este trabalho sumariza os principais aspectos da contaminação ambiental por interferentes endócrinos e o potencial de uso dos processos Fenton como processos oxidativos avançados na remoção destes micropoluentes. Palavras-chave:Processos oxidativos avançados; recursos hídricos; interferentes endócrinos.
