publicado na web em 11/07/2017 EMERGING CONTAMINANTS IN AQUATIC MATRICES FROM BRAZIL: CURRENT SCENARIO AND ANALYTICAL, ECOTOXICOLOGICAL AND LEGISLATIONAL ASPECTS. Emerging contaminants occur in parts per trillion or less in aquatic matrices. The effects related to the exposure of aquatic biota and human to them have been identified for different compounds. The knowledge about the concentrations of the exposure is the first step to perform risk assessments. The present work describes a literature review about occurrence in Brazilian aquatic matrices, and a discussion about biological effects, legislation and analytical aspects involving the presence of emerging compounds. The review includes 58 papers published between 1997 and 2016, considering the occurrence of personal care and pharmaceutical compounds, illicit drugs, hormones, pesticides and some other endocrine disruptors compounds in the matrices sewage, surface, ground and drinking waters. The concentrations varied from ng L -1 to μg L -1 , depending on the region and the compound. However, the contamination scenario was aggravated by the combination of poor sanitation status -such as low investment in sewage treatment plants, which led to an expressive contamination of the receiving waters with sewage -and the current goods consumption level, which is similar to that of developed countries. These data provide a good insight into the particular levels of contamination and can be used both for further researches and decision making in the regulation area of public policy.Keywords: emerging contaminants; endocrine disruptors compounds; drinking water; surface water; wastewater. CONTAMINANTES EMERGENTESA temática dos contaminantes emergentes ganhou destaque na década passada e vem sendo abordada em diferentes aspectos por pesquisadores do mundo todo. Tratam-se de centenas de compostos que têm sido detectados nos diferentes compartimentos ambientais (solo, água e ar), sendo eles tanto de origem antrópica (presentes em efluentes domésticos, industriais, hospitalares e aqueles provenientes das atividades agrícola e pecuária), quanto de ocorrência natural (presentes em diferentes espécies de plantas, por exemplo). Estes compostos podem apresentar algum risco ao ecossistema e eles não estão incluídos nos programas de monitoramento de rotina, ou seja, não são legislados. Assim, serão candidatos a uma futura regulamentação dependendo dos resultados obtidos em estudos de ecotoxicidade, efeitos à saúde humana, potencial de bioacumulação, transporte e destino nos diferentes compartimentos ambientais, além da quantidade em que são lançados e, portanto, da concentração no ambiente. Tratam-se de estudos que envolvem diferentes áreas da ciência e que têm sido considerados fundamentais para o esclarecimento dos novos paradigmas relacionados ao estilo de vida moderno. Conhecer os riscos associados à exposição por centenas de novos compostos que ainda não estão contemplados nas legislações vigentes permite antecipar e mitigar sérios danos para as gerações futuras.Muitos dos e...

“…Nasuhoglu et al [9] reported that EE2 can be degraded by about 90% and 50% in pure water and in industrial wastewater matrices, respectively, after 30 min of UVC treatment. Other studies also showed that UVC has the potential to effectively destruct EE2 in the order of mg/L by UVC [10][11][12], UVC/TiO 2 [11], UVC/H 2 O 2 [12,13] or UV/Fe 3+ [10] systems. However, more work has to be done to further optimize UV process and assess its efficiency to treat environmentally relevant EE2 concentrations in real wastewater matrices.…”

Please cite this article in press as: Z. Frontistis, et al., UV and simulated solar photodegradation of 17␣-ethynylestradiol in secondarytreated wastewater by hydrogen peroxide or iron addition, Catal. Today (2014), http://dx. a b s t r a c tThe extensive use of estrogens and their release, through various pathways, into the environment, constitutes an emerging environmental problem that poses serious threats onto public health. In this work the efficiency of UVC/H 2 O 2 and solar/Fe 2+ treatment to degrade 17␣-ethynylestradiol (EE2) in environmentally relevant concentrations of 100 g/L in secondary-treated wastewater matrices was investigated. Also, photolytic treatment was performed under different irradiation sources, namely UVC, UVA and simulated solar light. The effect of H 2 O 2 (0-20 mg/L) and Fe 2+ (0-15 mg/L) concentration was investigated and, at optimal operating parameters, EE2 removal was 100% after 15 min of UVC/H 2 O 2 treatment, while EE2 removal reached 86% after 60 min of solar/Fe 2+ treatment. In addition, the effect of water matrix and pH was studied. Total organic carbon (TOC) and yeast estrogen screening (YES) measurements showed the formation of stable intermediate products during EE2 treatment and an attempt to elucidate the reaction pathways and mechanisms through the identification of transformation products (TPs) by means of UPLC-MS/MS was made. Several TPs, including quinone methide and 1,2-quinone derivatives, were identified and competing pathways were suggested, in which hydroxylation, alkylation, dealkylation, demethylation and dehydroxylation, amongst others were described as major transformation mechanisms.

The protection and conservation of natural resources is one of the main priorities of modern society. Water is perhaps our most valuable resource, and thus should be recycled. Many of the current recycling techniques for polluted water only concentrate the pollutant without degrading it or eliminating it. In this sense, advanced oxidation processes are possibly one of the most effective methods for the treatment of wastewater containing organic products (effluents from chemical and agrochemical industries, the textile industry, paints, dyes, etc.). More conventional techniques cannot be used to treat such compounds because of their high chemical stability and/or low biodegradability. This article describes, classifies, and analyzes different types of advanced oxidation processes and their application to the treatment of polluted wastewater.
