“…PPs have been massively used and are considered emergent contaminants because they have been introduced in soils and waters through (i) human excretions in sewage collectors (especially from hospital effluents (Heberer, 2002)), (ii) disposal of unwanted, unused or expired products in the toilet or sink, and (iii) land application of animal manure (O'Connor and Aga, 2007) and treated sewage sludge (Kinney et al, 2006). PPs have been detected (at ng L − 1 and μg L − 1 levels) in a wide variety of water samples, such as effluents (from medical care units, landfills, and municipal sewage), seawater, drinking water, and surface-and groundwater, (Benotti et al, 2009;Fatta-Kassinos et al, 2011); but also in soils and sediments in concentrations ranging from μg kg − 1 to mg kg − 1 (Braganca et al, 2012;Li et al, 2012).…”

Zero-valent iron nanoparticles (nZVIs) are often used in environmental remediation. Their high surface area that is associated with their high reactivity makes them an excellent agent capable of transforming/degrading contaminants in soils and waters. Due to the recent development of green methods for the production of nZVIs, the use of this material became even more attractive. However, the knowledge of its capacity to de-grade distinct types of contaminants is still scarce. The present work describes the study of the application of green nZVIs to the remediation of soils contami-nated with a common antiinflammatory drug, ibuprofen. The main objectives of this work were to produce nZVIs using extracts of grape marc, black tea and vine leaves, to verify the degradation of ibuprofen in aque-ous solutions by the nZVIs, to study the remediation process of a sandy soil contaminated with ibuprofen using the nZVIs, and to compare the experiments with other common chemical oxidants. The produced nZVIs had nanometric sizes and were able to degrade ibuprofen (54 to 66% of the initial amount) in aqueous solutions. Similar remediation efficiencies were obtained in sandy soils. In this case the remediation could be enhanced (achieving degradation efficiencies above 95%) through the complemen-tation of the process with a catalyzed nZVI Fenton-like reaction. These results indicate that this remediation technology represents a good alternative to traditional and more aggressive technologies.

“…3,55 Valores altos de K d para FQ e TET indicam a grande tendência à sorção destes fármacos em solos e sedimentos, já que estes compostos são passíveis de interação com sítios negativos e positivos do solo devido à presença de diversos grupos ionizáveis e à capacidade de formação de espécies catiônicas, aniônicas ou zwiteriôni-cas. 37,38,64,71 No caso das TET, o grupo amônio quaternário, quando positivamente carregado, pode interagir com sítios aniônicos via troca catiônica. Já, o grupo tricarbonil metano ceto-enol, quando negativamente carregado, pode interagir com sítios positivos do solo via ponte catiônica.…”

“…Sendo assim, existe uma carência de dados quantitativos que estimem a extensão desta contaminação, de estudos sobre a mobilidade destes fármacos, de métodos adequados para a determinação dos mesmos no solo e dos impactos ambientais provocados por sua presença no ambiente. 4,38,103,104 O desconhecimento das consequências que podem ocorrer em longo prazo pela dispersão de bactérias resistentes fez com que países desenvolvidos adotassem medidas preventivas, a fim de evitar que estes micro-organismos fossem disseminados por meio do consumo de produtos de origem animal. Atualmente, os Estados Unidos, União Europeia e Japão dispõem de guias que regulamentam a avaliação de novos produtos veterinários no que diz respeito aos impactos ambientais e aos efeitos microbiológicos que podem ser provocados pelas bactérias de interesse à saúde humana.…”

“…However, relatively lower sensitivity (e.g. quantification limits ranging from sub-to low mg g À1 ) and poorer reproducibility were usually observed [35], which might be attributable to the highly complex and variable matrix effects of sludge and soil. Although FQs and TCs show comparable tendency for sorption to solids [30], present research usually determined the two classes of antibacterials separately [21,[31][32][33][34].…”

A reliable method was proposed for the simultaneous determination of five fluoroquinolones (FQs) and two tetracyclines (TCs) in sewage sludge using ultrasonic-assisted extraction (USE) followed by SPE cleanup and highperformance liquid chromatography-mass spectrometry (HPLC-MS)/MS analysis with electrospray ionisation (ESI) in a positive mode. The USE conditions (e.g. extraction solvent, pH, and extraction cycles) and highperformance liquid chromatography-tandem mass spectrometry (HPLC-MS/ MS) parameters were optimised. Quantification was performed by internal standard calibration in multiple reaction monitoring mode. Recoveries of the antibacterials ranged from 41 to 123%, with relative standard deviations within 17%. The sample-based limits of quantification were 10-63 ng g À1 dry weight (dw) for FQs (ciprofloxacin, enrofloxacin, lomefloxacin, norfloxacin, and ofloxacin) and 250-500 ng g À1 dw for TCs (tetracycline and oxytetracycline). The method was applied to determine the antibacterials in sewage sludge and sediment samples were collected from the Pearl River Delta, China. Ciprofloxacin, norfloxacin, and ofloxacin were frequently detected, ranging from 1052 to 17740 ng g À1 dw in dewatered sludge samples, 585-3545 ng g À1 dw in untreated solids, and 98-258 ng g À1 dw in an urban stream sediment sample, respectively. Lomefloxacin and enrofloxacin were also occasionally detected.
