Tartrazine is a commonly not-biodegradable dye used in food industries. The aim of this work was to evaluate the influence of operating conditions in the heterogeneous photo-Fenton process for the removal of tartrazine on structured catalysts. In particular LaFeO3 or Pt/LaFeO3 perovskite supported on honeycomb monoliths have been tested. The process efficiency was evaluated in terms of both dye discoloration and mineralization. The influence of initial dye concentration, H2O2 dosage, and initial pH of solution has been evaluated. Experimental results evidenced that the presence of the platinum allows the removal of the colour already in dark condition, enhancing the adsorption phase. Moreover, the highest photo-Fenton performances were obtained at natural solution pH (6), reaching the complete discoloration and...

In this study, we used quantitative PCR (qPCR) to determine the abundance of nine ARGs and a class 1 integron associated integrase gene in 16 wastewater treatment plant (WWTP) effluents from ten different European countries. In order to assess the impact on the receiving water bodies, gene abundances in the latter were also analysed. Six out of the nine ARGs analysed were detected in all effluent and river water samples. Among the quantified genes, intI1 and sul1 were the most abundant. Our results demonstrate that European WWTP contribute to the enrichment of the resistome in the receiving water bodies with the particular impact being dependent on the effluent load and local hydrological conditions. The ARGs concentrations in WWTP effluents were found to be inversely correlated to the number of implemented biological treatment steps, indicating a possible option for WWTP management. Furthermore, this study has identified bla OXA-58 as a possible resistance gene for future studies investigating the impact of WWTPs on their receiving water.

Urban wastewater treatment plants (UWTPs) are recognised sources for antibiotic resistance dissemination in the environment. Herein a novel cerium-doped zinc oxide (Ce-ZnO) photocatalyst is compared to ZnO and the benchmark TiO2-P25 in the immobilised form on a metallic support, to evaluate a photocatalytic process as a possible tertiary treatment in UWTPs. The catalysts were compared for the removal of two antibiotics, trimethoprim (TMP) and sulfamethoxazole (SMX), and for the inactivation of Escherichia coli (E. coli) strain DH5-Alpha in isotonic sodium chloride solution and of autochthonous bacteria in real secondary wastewater. In real wastewater, E. coli and other coliforms were monitored, as well as the respective fractions resistant to ofloxacin and azithromycin. In parallel, Pseudomonas aeruginosa and the respective sub-population resistant to ofloxacin or ciprofloxacin were also monitored...

This integration of environmental issues and disciplines is a prerequisite for adopting sustainable solutions to numerous contemporary environmental problems. The proceedings of the 7-11th CEST have been included in the major data banks, such as Science Citation Index (ISI), Chemical Abstracts and SRCosmos. In this issue, 25 papers, spanning a wide spectrum of scientifi c contributions were selected and reviewed. The authors and guest editors expect that this issue should provide an overview of recent works done in environmental pollution monitoring and control and fulfi l scientifi c gaps emphasized in many publications. The guest editors would like to thank all colleagues for their valuable contributions and express their appreciation to the Editor, Miriam Balaban and Associate Editor, Vincenzo Belgiorno, for providing this opportunity.

Current Opinion in Environmental Science & Health, 2018

The SCHEER concludes that, while the methodology chosen is appropriate and the report considers many important elements, the document is deficient in key details. In particular the report inadequately addresses (i) contaminants of emerging concern, (ii) antibiotic resistance spread through urban wastewater treatment plants' effluents, and (iii) possible risks associated with disinfection and/or advanced treatment of urban wastewater (e.g. formation of disinfection by products and related toxicity). Therefore, the SCHEER is of the opinion that the minimum quality requirements proposed provide insufficient protection both to environmental and human health. The SCHEER supports the case-by-case approach proposed, but recommends that common criteria be defined for the development of case-bycase assessments, in order to ensure comparable minimum quality requirements across EU Member States.

The effect of the total concentration of organics as dissolved organic carbon (100-500 mg/L), operating temperature (25-50 • C), dissolved iron concentration and their relationship to different process efficiency parameters (mineralization rate, hydrogen peroxide consumption and treatment time) were evaluated. Experiments were carried out under sunlight in a pilot plant. It consists of four compound parabolic collectors (CPCs) and a total volume of 75 L. From the results of the study it can be concluded that solar plants should be designed for operating at temperatures below 45 • C to avoid significant loss of iron. H 2 O 2 should be carefully dosed during the photo-Fenton treatment to avoid its continued excess and inefficient use.

In this study the effect of UV/H2O2 process on the potential of AR transfer was investigated through cultivation methods vs (polymerase chain reaction) PCR based methods. blaTEM was selected as target antibiotic resistance gene (ARG) and was quantified by qPCR in the survived colonies and the whole suspension (total DNA). The detection limit of residual antibiotic resistant Escherichia coli (E. coli) colonies (5CFUmL(-1)) was reached after 240min treatment, but blaTEM gene was still present in total DNA after 300min (2.8×10(6) copies mL(-1)), and no effect was observed in DNA extracted from cell cultures (3.8×10(8) copies mL(-1) after 90min). Accordingly, the investigated disinfection process may select for unaffected ARGs, therefore contributing to the potential transfer of AR in the environment.

The highest bacteria inactivation rate (all the target pathogens were inactivated below the detection limit (DL) (100 CFU/100 mL) within 45 min treatment) was observed for ozonation (83 mgO3/L h). Similar inactivation behavior for all bacteria was observed for sunlight/H2O2 (50 mg/L) and solar photo-Fenton (SPF) with EDDS (1:1 molar ratio, 0.1 mM of Fe and 50 mg/L of H2O2). Although the DL was not reached, faster inactivation kinetics (0.007, 0.013 and 0.002 1/min for E. coli, Salmonella spp. and Enterococcus spp., respectively) and lower bacterial concentration after a 180 min treatment were observed for sunlight/H2O2 process compared to SPF (0.005, 0.01 1/min and no inactivation, respectively), Enterococcus spp. being the higher resistance microorganism. The negative effect of carbonates on disinfection performance was also evaluated. Quantitative microbial risk assessment for the ingestion of lettuce irrigated with untreated and treated WW was estimated. Disinfection by ozonation and sunlight/H2O2 processes were found to drastically decrease the associated microbiological risk (the mean risk of illness decreased from 0.10 (untreated) to 1.35 × 10-4 (treated) for E. coli and from 0.03 to 2.21 × 10-6 for Salmonella).

The degradation of the contaminants well fit pseudo-first order kinetic model. Diclofenac effectively degraded even by solar photolysis. Faster degradation of pharmaceuticals by sunlight/NeTiO 2 compared to sunlight/H 2 O 2. Sunlight/NeTiO 2 process would result in a smaller treatment volume than sunlight/H 2 O 2 .

In this manuscript, homogeneous solar-driven advanced oxidation processes (AOPs), namely H2O2/sunlight, solar photo-Fenton (Fe+2/H2O2/sunlight) and solar photo-Fenton with ethylenediamine-N,N'-disuccinic acid (EDDS) complex (Fe+2/H2O2/EDDS/sunlight) were compared to a new heterogeneous process (supported nitrogen-doped TiO2 (N-TiO2)/sunlight), with the aim of contributing to fill the gap between lab scale tests and full scale applications as well as to provide a sustainable solution for tertiary treatment in small UWTPs. Process efficiency was evaluated in terms of effluent toxicity and degradation of a mixture of three pharmaceuticals (namely carbamazepine (CBZ), diclofenac and trimethoprim), at initial concentration of 200 µg/L each, in deionized water (DW) and real wastewater (WW). Fe2+/H2O2/EDDS/sunlight was found to be the most effective process (98% removal of CBZ from WW in 60 min, 5.6 kJ/L as cumulative solar energy per unit of volume). Conventional solar photo Fenton was drastically and negatively affected by water matrix, due to the spontaneous neutral pH and iron precipitation in real WW. Although N-TiO2/sunlight process was not so affected by water matrix, it was found to be less efficient (30% removal of CBZ in 180 min, 13.3 kJ/L) than Fe2+/H2O2/EDDS/sunlight process. Toxicity values were found to be lower in WW compared to DW matrix. Class weight scores for WW samples showed a toxicity reduction up to the no acute toxicity level for N-TiO2/sunlight and Fe2+/H2O2/EDDS/sunlight treatments, while H2O2/sunlight and Fe2+/H2O2/sunlight increased the final effluent toxicity up to slightly acute levels.

Unfortunately, they are classified as endocrine disrupting chemicals (and also considered as contaminants of emerging concern) having adverse effects on animal and human reproduction. The treatment of nonylphenol-decaethoxylated (NP-10) via H2O2/UV-C process at different reaction times (5, 10, 20, 40, 80 min) and H2O2 concentrations was investigated. After 80 min treatment the removal rates of NP-10 solution (initial concentration 100 mg/L) in deionized water were 88%, 97% and 98% for 10, 20 and 100 mg/L of H2O2 respectively. The same experimental conditions were applied to real wastewater spiked with 100 mg/L of NP-10 showing the following removal rates: 84%, 98% and 99%, respectively. The possible contribution of different radicals to NP-10 degradation by H2O2/UV-C treatment was investigated by evaluating the effect of different radical scavengers (namely NO3-, NaCl, Na2SO4, Na2CO3, KH2PO4 and phatalate). Toxicity data (Aliivibrio fischeri, Raphidocelis subcapitata and Daphnia magna) on treated solutions and wastewater highlighted the presence of residual toxicity in all samples evidencing that no complete mineralization occurred.
