“…construídos). No entanto, estudos com lodos ativados predominam na literatura (STUMPF et al, 1999;SUÁREZ et al, 2008;HYLAND et al, 2012;FISCHER;MAJEWSKY, 2014;GRANDCLÉMENT et al, 2017;GROS et al, 2017;BALAKRISHNA et al, 2017), principalmente porque os demais sistemas não são muito utilizados nos países que mais desenvolvem pesquisas com fármacos, como EUA, Canadá, Coreia, China, Japão e países europeus (AQUINO; BRANDT; CHERNICHARO, 2013).…”

“…Contudo, as principais vias de degradação dos fármacos durante o tratamento por lodos ativados se resumem aos processos de biodegradação metabólica e co-metabólica, e sorção em flocos do lodo, podendo ocorrer ainda degradação quí-mica por processo abiótico (HYLAND et al, 2012;BITTENCOURT et al, 2016;GRANDCLÉMENT et al, 2017). Para produtos farmacêuticos, a volatilização é desprezível, pois além da elevada massa molar a constante da Lei de Henry (KH), que determina o equilíbrio entre moléculas em solução na fase líqui-da com aquelas presentes na fase gasosa, costuma apresentar valores abaixo do mínimo (KH 10-5) para haver volatilização (SUÁREZ et al, 2008).…”

“…As biodegradações co-metabólicas também apresentam caráter significativo na remoção de fármacos, já que por causa da complexidade dos compostos e das suas concentrações muito baixas podem não servir como substrato facilmente acessível aos microrganismos em um primeiro momento (FISCHER;MAJEWSKY, 2014;GRANDCLÉMENT et al, 2017). Portanto, a biodegradação associada à sorção em lodo pode promover a redução das concentrações de alguns produtos farmacêuticos em sistemas biológicos, como apresentado na Tabela 5.…”

ResumoA presença de micropoluentes em águas residuárias e naturais, como fármacos, tem despertado preocupação na comunidade científica devido a sua ocorrência, persistência e potencial deletério à saúde humana e aos ecossistemas. Tal preocupação tem sido impulsionada pela capacidade de detecção de substâncias químicas por equipamentos avançados e métodos mais sensíveis. Dessa forma, estudos de investigação e técnicas de tratamento para degradação de compostos farmacêuticos em matrizes aquosas estão sendo intensificados. Diante da relevância do assunto, este artigo consiste em uma revisão da literatura sobre fármacos largamente encontrados no ambiente, principalmente em águas residuárias e superficiais. Palavras-chave: Micropoluentes. Determinação analítica. Tratamento. AbstractThe presence of micropollutants in wastewater and natural waters, such as pharmaceuticals, have aroused concern in the scientific community due to their occurrence, persistence and deleterious potential to human health and ecosystems. Such concern has been boosted by the ability to detect chemicals by advanced equipment and more sensitive methods. Thus, research studies and treatment techniques for the degradation of pharmaceutical compounds in aqueous matrices are being intensified. Given the relevance of the subject, this article consists of a review of the literature on pharmaceuticals widely found in the environment, mainly in wastewater and surface water.

“…Depending on the compound and the specific process employed, AOPs can create by-products that are potentially as harmful as the starting compound (Schlüter-Vorberg, Prasse, Ternes, Mückter, & Coors, 2015). Activated carbon could also be considered, but using granular activated carbon (GAC) in a column could run the risk of the chromatographic effect (wherein the effluent concentration could exceed the influent concentration due to competitive adsorption) and powdered activated carbon (PAC) achieves a low loading (mass of contaminant removed per mass of carbon) because, at best, it achieves equilibrium Research Article with the effluent concentration (Benjamin & Lawler, 2013;Grandclément et al, 2017). Enzymatic treatment using laccases (a product of white-rot fungi) could be an alternative for removing PPCPs and other recalcitrant compounds in municipal wastewater.…”

Laccases were studied for their ability to remove two compounds, 2‐chlorophenol and sulfamethoxazole, in batch studies, both in buffered solutions and in wastewater samples from different points in a municipal water resource recovery facility. Two enzymes with and without a mediator (acetosyringone) were investigated: a commercial product derived from Myceliphthora thermophile and a laboratory‐generated enzyme mix derived from Tramates versicolor. The chlorophenol was removed rapidly by the commercial enzyme in the presence of acetosyringone, but the primary products were coupling complexes of the reactants. Excellent removal was achieved without acetosyringone by the natural enzyme mix. Sulfamethoxazole was poorly removed in all laboratory‐generated chemically buffered solutions, but was very well removed, without the addition of mediators, in secondary effluent suspensions from a municipal water resource recovery facility. Mechanistic studies are still required, but the results suggest that treatment via direct addition of enzymes is feasible to remove recalcitrant compounds in municipal wastewater.

“…The discharge of trace levels of pharmaceuticals, industrial chemicals, pesticides and personal care products into aquatic environments is an issue of global environmental concern (1–3). Because of their resistance to conventional wastewater treatment and environmental persistence as complex mixtures, these organic micropollutants (OMPs) present risks of adverse ecological impact to biota via direct toxicity and endocrine disruption (4–6).…”

15Organic micropollutants (OMPs) are pervasive anthropogenic contaminants of fresh and 16 marine waters with known potential to adversely affect aquatic life (e.g. endocrine disruption). 17Their ubiquitous environmental occurrence is primarily attributed to wastewater treatment 18 plant discharges following their incomplete removal by common biological treatment 19 processes. This study assesses a new strategy for promoting the degradation of six model OMPs 20 (i.e. sulfamethoxazole, carbamazepine, tylosin, atrazine, naproxen and ibuprofen) by 21 stimulating microbial oxidoreductase production to counter the effects of oxidative stress 22 caused by oxygen perturbation. Microbial cultures from dairy farm wastewater were exposed 23 to a cyclical ON-OFF perturbations of oxygen supply, ranging from 0.16 to 2 cycles per hour 24 (i.e. 2, 1, 0.5, 0.25 and 0.16 cycles/hour), in laboratory bioreactors. The activity and relative 25 abundances of microbial oxidoreductases (such as peroxidases, cytochromes P450) were 26 upregulated by oxygen perturbation. In comparison to controls subjected to constant oxygen 27 levels, OMP concentrations in perturbed cultures decreased by 70±9% (mean ± SD). A 28 distance-based linear model confirmed strong positive correlations between the relative 29 abundance of the bacterial families, Rhodocyclaceae, Syntrophaceae and 30 Syntrophobacteraceae, and oxygen perturbations. Our results confirm that intentional 31 perturbation of oxygen supply to induce microbial oxidative stress can improve OMP removal 32 efficiencies in wastewater treatment bioreactors. 33 Microbial communities | Oxidoreductase activity | Bioreactor aeration regime | Wastewater 34 OMPs removal 35 36 37 38 39 40 41 42 43 44 45 Significance 46 47Oxygen concentration is a critical control variable for biological processes in conventional 48 wastewater treatment systems. We provide a simple approach that could be used in existing 49 wastewater treatment infrastructure to enhance removals of otherwise persistent OMPs by 50 exploiting oxidative stress responses of microbes. Our study illustrates the ability of fluctuating 51 oxygen conditions to affect microbial activity and polulation by upregulating oxidoreductases 52 linked to the removal of organic micropollutants. The incorporation of inexpensive and easy to 53 implement dissolved oxygen supply strategies for more efficient OMPs biotransformation 54 provides a realistic approach to improving the treatment performance of biological processes. 56Because of their resistance to conventional wastewater treatment and environmental 60 persistence as complex mixtures, these organic micropollutants (OMPs) present risks of 61 adverse ecological impact to biota via direct toxicity and endocrine disruption (4-6). For 62 example, occurrence of the herbicide, atrazine, even at concentrations below 6 µg/L in 63 receiving waters, caused behavioural changes in the zebrafish, Brachydanio rerio, such as a 64 preference for dark habitats and alterations in swimming due to failure of its nervou...
