“…For this C-WWTP2 has an activated sludge treatment too, but in this WWTP the study was conducted in the tertiary process which is based on electrodialysis reversal. This technology has been demonstrated as an effective way to remove some emerging pollutants from drinking water [30] but studies in wastewaters are scarce and for this reason, this tertiary process was evaluated. In this wastewater treatment plant, the samples were taken after the secondary process (point B1) and after the electrodialysis technology (point B2).…”

To encourage the reutilization of treated wastewaters as an adaptation strategy to climate change it is necessary to demonstrate their quality. If this is ensured, reclaimed waters could be a valuable resource that produces very little environmental impact and risks to human health. However, wastewaters are one of the main sources of emerging pollutants that are discharged in the environment. For this, it is essential to assess the presence of these pollutants, especially pharmaceutical compounds, in treated wastewaters. Moreover, the different treatment processes must be evaluated in order to know if conventional and natural treatment technologies are efficient in the removal of these types of compounds. This is an important consideration if the treated wastewaters are used in agricultural activities. Owing to the complexity of wastewater matrixes and the low concentrations of pharmaceutical residues in these types of samples, it is necessary to use sensitive analytical methodologies. In this study, the presence of 11 pharmaceutical compounds were assessed in three different wastewater treatment plants (WWTPs) in Gran Canaria (Spain). Two of these WWTPs use conventional purification technologies and they are located in densely populated areas, while the other studied WWTP is based in constructed wetlands which purify the wastewaters of a rural area. The sampling was performed monthly for two years. A solid phase extraction (SPE) coupled to ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method was applied for the analysis of the samples, and the 11 pharmaceuticals were detected in all the studied WWTPs. The concentrations were variable and ranged from ng·L−1 in some compounds like diclofenac or carbamazepine to µg·L−1 in common pharmaceutical compounds such as caffeine, naproxen or ibuprofen. In addition, removal efficiencies in both conventional and natural purification systems were evaluated. Similar removal efficiencies were obtained using different purifying treatments, especially for some pharmaceutical families as stimulants or anti-inflammatories. Other compounds like carbamazepine showed a recalcitrant behavior. Secondary treatments presented similar removal efficiencies in both conventional and natural wastewater treatment plants, but conventional treatments showed slightly higher elimination ratios. Regarding tertiary system, the treatment with highest removal efficiencies was reverse osmosis in comparison with microfiltration and electrodialysis reversal.

“…Some conventional treatments in DWTPs, such as filtration, oxidation and adsorption, may remove some of these contaminants. Several studies demonstrated that oxidative processes particularly the use of chlorine are important strategies to reduce ECs levels in DWTPs (Rigobello et al, 2013;Gabarr on et al, 2016). The use of granular filters, such as sand, is also a common strategy applied in DWTPs with low ability to remove ECs (Pojana et al, 2011;Gabarr on et al, 2016).…”

2017). Estudio piloto de la toxicidad de los sedimentos del río Pasto en el tramo La Playita-Puente La Carolina, asociada al uso de pesticidas. Bogotá, 14(1), 194-210. DOI: org/xx/xxxxx/reds.xxxx. ResumenEl objetivo del presente estudio piloto fue analizar la toxicidad de los sedimentos del río Pasto en el tramo La Playita-Puente La Carolina en la cuenca alta, una zona con importante actividad agropecuaria donde el agua tiene múltiples usos, utilizando bacterias bioluminiscentes Vibrio fischeri como bioindicadores de toxicidad. El estudio se basó en la hipótesis de que ciertos microcontaminantes derivados del uso pesticidas en la zona, son transportados entre las matrices aguas/sedimentos y son los responsables de los niveles de toxicidad hallados. Los resultados señalan niveles variables de toxicidad y posiblemente el fenómeno predominante sea el transporte de pesticidas o sus metabolitos en la masa de agua. Además, se infiere que posiblemente la concentración de plaguicidas no sea la principal causa de los niveles de toxicidad hallados y probablemente podrían asociarse a otras sustancias derivadas del vertimiento de aguas residuales y lixiviados. AbstractA screening toxicity was carried out at sediments of the Pasto River on the stretch La Playita-Puente La Carolina at its upper basin. This is meaningful farming area where water has multiple uses. For this 195 purpose, was determined the acute toxicity from sediments by using the photo-luminescent bacteria Vibrio fischeri. The hypothesis of the study was that any microcontaminants derived from pesticides uses on the stretch are transported between water/sediments matrix and are responsible for the levels of toxicity found. Varying levels of toxicity were found and possibly the predominant phenomenon is the transport of pesticides or their metabolites in the body of water. In addition, it is inferred that the concentration of pesticides may not be the main cause of the levels of toxicity found and could be associated with other substances derived from the dumping of waste water and leachate.
