“…Consequently, drinking water has been identified as one of the main routes of human exposure (Llorca et al, ). Although very rare, PFAS concentrations above the proposed standard value of 0.1 μg/L (Council of the European Union, , see Appendix 2) were detected in tap water samples from Spain, France, and Germany (Llorca et al, ; Schwanz, Llorca, Farré, & Barceló, ). In contrast, all tap water and bottled water samples from Germany that were analyzed by Gellrich, Brunn, and Stahl () were far below this limit.…”

In several European countries and at the level of the European Union, we can observe political and societal attempts to promote the use of tap water. Most prominently, the European Commission proposed revisions for the Drinking Water Directive, which includes strategies for promoting the consumption of tap water. The strategies comprise the following: improving access to tap water, upgrading quality standards for tap water, and enhancing transparency concerning the benefits of tap water. National initiatives in European countries pursue similar strategies that concentrate on enhancing access to tap water and communicating its economic, environmental, and social benefits. By drawing on existent literature in different disciplines, we assess how promising these strategies are for inducing individuals to drink tap water rather than bottled water. Our overview reveals that our knowledge regarding the quality dimension is very good: numerous studies on European countries have shown that dissatisfaction with the sensory properties and health-related concerns prevent individuals from drinking (more) tap water and opting for bottled water instead. The body of research with a specific focus on Europe is significantly smaller concerning the other two dimensions: access to tap water and the benefits of tap water. Nonetheless, there is indicative and preliminary evidence that improved access to tap water and a better communication of the benefits of tap water could positively affect consumption patterns.

“…187 Mais recentemente, com a possibilidade de se fazer a extração em linha com a determinação por LC-MS/MS, técnica denominada SPE on line, houve uma redução significativa no tempo de análise e quantidade de solventes empregados no preparo de amostras. 28,188,189 Além da SPE, outras técnicas de preparo de amostras também são utilizadas para a determinação de micropoluentes no ambiente, por exemplo, a microextração em fase sólida (SPME), que faz uso de uma fibra de material sorvente para a extração dos compostos por imersão ou por headspace; a QuECheRS (do inglês, Quick, Easy, Cheap, Effective, Ruged and Safe), que utiliza como etapa inicial a extração por um solvente (originalmente acetonitrila), em seguida adição de sais e separação de fase, etapa de limpeza (clean up) e adição de padrão interno para posterior determinação dos analitos; dentre outras técnicas. [190][191][192][193] Concomitantemente com a otimização das técnicas analíticas, foram desenvolvidos e aprimorados diferentes bioensaios (os quais utilizam organismos vivos para avaliar um efeito de uma substância ao qual foram expostos por um período conhecido de tempo) como ferramentas capazes de fornecer informações adicionais aos ensaios ecotoxicológicos, sobre os efeitos estrogênicos, androgênicos, de sinergismo ou influências antiestrogênicas relacionadas à presença de inúmeros contaminantes em uma amostra complexa.…”

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...

“…So far, several previous studies have reported the occurrence of PFASs, especially PFOA and PFOS in WWTPs and tap water globally (Ericson et al, 2008;Huset et al, 2008;Jin et al, 2009;Quiñones and Snyder, 2009;Quinete et al, 2009;Arvaniti et al, 2012;Zhang et al, 2013;Schwanz et al, 2016). However, very limited information is available for the various PFASs in DWTPs (Shivakoti et al, 2010;Takagi et al, 2011;Thompson et al, 2011;Eschauzier et al, 2012;Flores et al, 2013).…”
