“…Zhang et al (2013a) also observed that non-charged compounds, such as CAFF, were easily incorporated by Scirpus validus, an aquatic plant. Nevertheless, in comparison with previous laboratory studies with synthetic river water, the effect of vegetation on the removal of CAFF was much lower (Matamoros et al 2012b). This can be explained by the differences in the water composition used in the different studies, as the content of organic matter and bacteria is, in general, higher in secondary-treated wastewater than surface water.…”

“…The values for CAFF and IBP calculated in this study were higher than those previously found in a laboratory-scale study with Lemna sp. incubated under synthetic surface water (0.18 and 0.02 day -1 , respectively) (Matamoros et al 2012b). In the present study, the composition of the secondary-treated wastewater substantially enhanced the IBP kinetic removal rate values.…”

(Matamoros et al 2012b;Reinhold et al 2010) can enhance the removal of pharmaceuticals such as ibuprofen and caffeine, whereas in the case of diclofenac, sulfonamides and tetracyclines they are mainly removed by photodegradation (Andreozzi et al 2003;Garcia-Rodríguez et al 2013).…”

The presence of pharmaceuticals and endocrine-disrupting chemicals (EDCs) in wastewater treatment plant effluents is an issue of great concern due to the negative effects that these compounds may have on human health and ecosystems. The present study aims to assess the capacity of two aquatic plants (Lemna sp. and Spirogyra sp.), commonly found in polishing ponds, for removing six pharmaceutical compounds (diclofenac, acetaminophen, ibuprofen, carbamazepine, clofibric acid, and propranolol), two EDCs (17a-ethinylestradiol and bisphenol A), and one stimulant (caffeine) under laboratory-scale conditions. Planted and unplanted reactors fed with secondary-treated wastewater or ultrapure water in both covered and uncovered conditions were studied. The highest removal efficiencies, which ranged from 31 to 100 %, were achieved in uncovered planted systems containing secondary-treated wastewater after 20 days of incubation. The results demonstrated that non-charged compounds with a log Kow between 2 and 4 were affected by the presence of vegetation, probably due to their plant uptake, whereas negatively charged compounds were not. This highlights that the presence of plants in polishing ponds plays an important role in the removal of pharmaceuticals and EDCs.

“…These pollutants may contaminate surface waters from point sources typically associated with concentrated farming activities or from diffuse or non-point sources associated with surface runoff (which may be potentially more problematic due to the difficulty to intercept and treat those pollution sources). Examples of insidiously challenging cases of agricultural pollution sources are the wastewaters resulting from the production of livestock such as piggeries, or food industries such as olive oil production, and situations of water contamination with pesticides after runoff events (Cronk, 1996;Fiorentino et al, 2003;Justino et al, 2012;Matamoros et al, 2012b).…”

H I G H L I G H T S• CW with LECA substrate and Phragmites plants tested with agricultural wastewaters.• High removals of TSS, COD, NH 4 -N, polyphenols, a pharmaceutical and a pesticide.• Contact time of wastewaters with beds ranged from 3 to 9days in batch conditions.• Promising results suggest more studies in full-scale and more realistic conditions. Constructed wetlands (CWs) are receiving a renewed attention as a viable phytotechnology for treating agricultural wastewaters and for the removal of more specific pollutants, in particular recalcitrant ones. In this work, the performance of CW mesocosms using light expanded clay aggregates (LECA) as the bed's substrate and planted with Phragmites australis was investigated for treatment of olive mill wastewater (OMW), swine wastewater (SW) contaminated with oxytetracycline and water contaminated with herbicide MCPA (2-methyl-4-chlorophenoxyacetic acid). Both wastewaters (OMW and SW) initially presented high organic matter content and total suspended solids which were removed by the system with efficiencies higher than 80%. Removal of polyphenols in OMW and nitrogen compounds in SW also showed similar or higher efficiencies in comparison with other treatment systems reported in the literature. The antibiotic oxytetracycline was completely removed from SW within the assay period in unplanted LECA beds, but planted beds allowed a significantly faster removal. In regard to water contaminated with MCPA, the results showed that LECA has a large sorption capacity for this herbicide (removal efficiencies of 56-97%). In general, considerably higher pollutant removal efficiencies were obtained when plants were used (up to 28% higher). The results obtained are indicative that CWs with LECA as substrate may be an adequate option for agricultural wastewater treatment. a b s t r a c t a r t i c l e i n f o
