“…6 ASWs are excreted mostly unchanged from the human body, flow down the drain, and are discharged into the environment through wastewater treatment plants (WWTPs). 7, 8 Hydrophilic ASWs (solubility = 565−9.1 × 10 5 mg/L at 25°C) ( Table 1) are not efficiently removed through wastewater treatment processes. For instance, removal efficiencies for acesulfame and sucralose in WWTPs were reported to be <20%.…”

Very few studies describe the fate of artificial sweeteners (ASWs) in wastewater treatment plants (WWTPs). In this study, mass loadings, removal efficiencies, and environmental emission of sucralose, saccharin, aspartame, and acesulfame were determined based on the concentrations measured in wastewater influent, primary effluent, effluent, suspended particulate matter (SPM), and sludge collected from two WWTPs in the Albany area of New York State, U.S.A. All ASWs were detected at a mean concentration that ranged from 0.13 (aspartame) to 29.4 μg/L (sucralose) in wastewater influent, 0.49 (aspartame) to 27.7 μg/L (sucralose) in primary influent, 0.11 (aspartame) to 29.6 μg/L (sucralose) in effluent, and from 0.08 (aspartame) to 0.65 μg/g dw (sucralose) in sludge. Aspartame was found in 92% of influent SPM samples at a mean concentration of 444 ng/g dw, followed by acesulfame (92 ng/g) and saccharin (49 ng/g). The fraction of the total mass of ASWs sorbed to SPM was in the rank order: aspartame (50.4%) > acesulfame (10.9%) > saccharin and sucralose (0.8%). The sorption coefficients of ASWs ranged from 4.10 (saccharin) to 4540 L/kg (aspartame). Significant removal of aspartame (68.2%) and saccharin (90.3%) was found in WWTPs; however, sucralose and acesulfame were less efficiently removed (<2.0%). The total mass loading of sucralose, saccharin, and acesulfame in the WWTP that served a smaller population (∼15 000) was 1.3−1.5 times lower than that in another WWTP that served a larger population (∼100 000). The average daily loading of sucralose in both WWTPs (18.5 g/d/1000 people) was ∼2 times higher than the average loading of saccharin. The daily discharge of sucralose from the WWTPs was the highest (17.6 g/d/1000 people), followed by acesulfame (1.22 g/d/1000 people), and saccharin (1.07 g/d/1000 people). Approximately, 1180 g of saccharin and 291 g of acesulfame were transformed in or removed daily from the two WWTPs. This is the first study to describe the fate of ASWs, including the fraction found in SPM and in sludge, in addition to the aqueous portion of wastewater in WWTPs.

“…Some WWTPs also discharge effluents to lagoons for enhanced treatment, through settling and extended exposure to solar irradiation and microbial activity (Li et al, 2013). Lagoon-based wastewater treatment consists of wastewater flowing through shallow, open ponds with extended hydraulic retention times, typically between 7 and 20 days (Hoque et al, 2014). As an enhanced treatment process, lagoon-based treatments are less expensive and may be as equally efficient as conventional wastewater treatments in removing organic contaminants.…”

“…Few studies, however, have evaluated the effectiveness of lagoons in removing organic pollutants and they only asses the removal of the parent compound (Hoque et al, 2014;Conkle et al, 2008;Lishman et al, 2006;MacLeod and Wonga, 2010;Camacho-Muñoz et al, 2012;Carlson et al, 2013). Pharmaceuticals may undergo transformation during wastewater treatment, however, giving rise to transformation products (TPs) which can be more persistent and biologically active than the original compounds (Farre et al, 2008;Escher and Fenner, 2011).…”

“…Since conventional wastewater treatment plants (WWTPs) are not designed to treat this type of contaminants, many of these compounds occur at different concentrations in natural water bodies [2], where they may exert ecotoxicological effects at relatively low concentrations [3,4]. Of the better studied cases, galaxolide has been found to inhibit the cellular multixenobiotic defense systems of marine mussels [5], tris(2-chloroethyl) phosphate has been shown to be carcinogenic, reproductive and neural toxic in animal cell cultures [6], and 4-octylphenol has high potential estrogenic effects on amphibian Xenopus laevis [7]. As consequence, known environmental effects of the occurrence of emerging contaminants in surface waters are the reduction of macroinvertebrate diversity in rivers [3] and behavioural changes in mosquito fish [4].…”

Henry's law constant higher than 3 10 -1 Pa m 3 mol -1 (i.e. 4-octylphenol, galaxolide, and tributyl phosphate) were removed by volatilization due to the effect of air stripping. Whereas biodegradation was relevant for removing ibuprofen and caffeine, carbamazepine and tris(2-chloroethyl) phosphate behaved as recalcitrant. The use of microalgae was proved to be relevant for increasing the biodegradation removal efficiency of ibuprofen by 40% and reducing the lag phase of caffeine by 3 days. Moreover, the enantioselective biodegradation of S-ibuprofen suggested a biotic predominant removal process, which was supported by the identification of carboxy-ibuprofen and hydroxy-ibuprofen. The results from microalgae reactors fed with nutrients showed no clear evidences of microalgae uptake of any of the studied microcontaminants.
