“…BuP was also found in 2 WWTPs in China, with the in uent concentration of 4.07-27 ng/L and the e uent ranging from 0.005-3 ng/L. The current study represents a lower concentration of BuP than the studies in China, Australia, and Brazil(Derisso et al, 2020;Evans et al, 2016;. Lower concentrations were noted, which shows that these chemicals were applied or used sparingly and that the target compounds were effectively removed throughout the removal process.…”

In the present work, wastewater treatment plant and sewerage drains from Nagpur, Central India were studied for frequently occurring endocrine disrupting chemicals (EDCs). All the EDCs, such as bisphenol A (BPA), butylparaben (BuP), and diethyl phthalate (DEP) were present in all the collected samples with a detection frequency of 100%. Laboratory analysis revealed high BPA, BuP, and DEP levels, with mean concentrations of 79.10 ng/L, 4.12 ng/L, and 2.25 µg/L, respectively, in influent samples and 33.20 ng/L, 1.62 ng/L, and 0.77 µg/L, respectively, in effluent wastewater. The distribution of the emergent pollutants among the sampling locations was found to be consistent with the physico-chemical characteristics of wastewater, according to the component analysis, and the sites with the highest levels of contamination were also identified. Finally, an ecological risk assessment was carried out for aquatic biota in terms of risk quotients (RQs). The RQs for the target chemicals in effluent wastewater suggested a minimal impact, except for the target insect Chrironomus riparius, which had an RQ value of 33.20 for BPA.

“…Analyses were performed for the beginning and end of incubation period, with collection in different periods of days of the cycle. A mix of 12 PPCPs contaminants commonly found in WWTP all over the world was prepared and the adopted concentrations were based on the maxima values reported in the literature (Dias, 2014;Lima et al, 2017;Bisognin et al, 2018;Derisso et al, 2020): ACM (60.0 µg L − ), MET (1.00 µg L −1 ), MEP (1.00 µg L −1 ), CBZ (4.00 µg L −1 ), NAP (15.0 µg L −1 ), ESN (0.10 µg L −1 ), EST (4.00 µg L −1 ), DIC (15.0 µg L −1 ), BZN (1.00 µg L −1 ), IBU (300 µg L −1 ), PRO (0.10 µg L −1 ), and AM (1.00 µg L −1 ). Samples were collected in different periods during 7 days using a syringe connected to a glass tube inside the reactor (Supplementary Figure S1).…”

An analytical method was developed to quantify a mixture of acetaminophen, metoprolol, methylparaben, carbamazepine, naproxen, estrone, estradiol, diclofenac, benzophenone, ibuprofen, progesterone, and mefenamic acid from domestic wastewater samples. To match fast and efficient chromatographic separation for different classes of compounds, an automated scouting liquid chromatographic system was associated with the experimental design produced by the DryLab® software. HLB cartridges were used to extract the analytes from the sample matrix, which was followed by detection and quantitation by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The lowest detection limits were found for acetaminophen and carbamazepine (0.625 pg L−1) and metoprolol (0.4 pg L−1).

“…Two personal care products (benzophenone-3 (BP-3) and propylparaben (PPB)) and the insecticide fipronil (FIP) were selected as model pollutants and were added to the matrix at an initial concentration of 100 µg L −1 each. These contaminants were selected because they have been detected in surface water [ 20 , 21 ], raw wastewater [ 22 , 23 , 24 , 25 , 26 ], treated effluent [ 15 , 27 , 28 ], groundwater [ 29 ] and drinking water [ 30 ] and are associated with toxic effects [ 15 , 31 ]. Moreover, to the best of our knowledge, no studies evaluating the simultaneous degradation of these compounds by advanced oxidation processes have been reported, and the majority of the reported studies evaluated the degradation of these compounds in distilled water and at higher concentrations (mg L −1 ) [ 32 ], which do not represent the reality of the concentration levels (trace level) frequently detected in real matrices.…”

Effect of Iron Complex Source on MWWTP Effluent Treatment by Solar Photo-Fenton: Micropollutant Degradation, Toxicity Removal and Operating Costs

et al. 2022

Benzophenone-3, fipronil and propylparaben are micropollutants that are potential threats to ecosystems and have been detected in aquatic environments. However, studies involving the investigation of new technologies aiming at their elimination from these matrices, such as advanced oxidation processes, remain scarce. In this study, different iron complexes (FeCit, FeEDTA, FeEDDS and FeNTA) were evaluated for the degradation of a mixture of these micropollutants (100 µg L−1 each) spiked in municipal wastewater treatment plant (MWWTP) effluent at pH 6.9 by solar photo-Fenton. Operational parameters (iron and H2O2 concentration and Fe/L molar ratio) were optimized for each complex. Degradation efficiencies improved significantly by increasing the concentration of iron complexes (1:1 Fe/L) from 12.5 to 100 µmol L−1 for FeEDDS, FeEDTA and FeNTA. The maximum degradation reached with FeCit for all iron concentrations was limited to 30%. Different Fe/L molar ratios were required to maximize the degradation efficiency for each ligand: 1:1 for FeNTA and FeEDTA, 1:3 for FeEDDS and 1:5 for FeCit. Considering the best Fe/L molar ratios, higher degradation rates were reached using 5.9 mmol L−1 H2O2 for FeNTA and FeEDTA compared to 1.5 and 2.9 mmol L−1 H2O2 for FeEDDS and FeCit, respectively. Acute toxicity to Canton S. strain D. melanogaster flies reduced significantly after treatment for all iron complexes, indicating the formation of low-toxicity by-products. FeNTA was considered the best iron complex source in terms of the kinetic constant (0.10 > 0.063 > 0.051 > 0.036 min−1 for FeCit, FeNTA, FeEDTA and FeEDDS, respectively), organic carbon input and cost-benefit (USD 327 m−3 > USD 20 m−3 > USD 16 m−3 > USD 13 m−3 for FeEDDS, FeCit, FeEDTA and FeNTA, respectively) when compared to the other tested complexes.
