“…A great deal of work has been done to monitor the concentration in both influent and effluent of WWTPs in China and worldwide [14][15][16]. Numerous antibiotics have been detected in groundwater, river basins and seawater [17][18][19]. Besides, in recent years, a number of researches have reported the occurrence of PhACs in China, mainly focused on Pearl River Delta [20,21], Yangtze River estuary [22][23][24], Bohai bay [25], Yellow River [26,27] and freshwater lakes [28][29][30].…”

“…The active ingredients selected for our analysis on the 3 monitored sites were mainly herbicides, with few fungicides and an insecticide, because herbicides are the main source of contamination of water bodies (Lopez et al, 2015). As shown in Table 1, they cover a wide range of the main physicochemical properties involved in transfer, DT50, K oc and solubility (Chen et al, 2015), and are applied during autumnwinter and/or spring on different crop types and at different rates.…”

“…Nevertheless, side effects on the environment (Richardson 1998) and in particular on water quality (Flury et al, 1995;Real et al, 2005;Grung et al, 2015;Lopez et al, 2015) have been observed. Consequently, regulations have been strongly reinforced, first by the European Water Framework Directive 2000/60/CE followed by various action plans which have come into existence, such as the Pesticide Package 2009/128/CE.…”

• Information on predictive quality of pesticide risk indicators is scarce • Outputs of 26 indicators and 1 model were compared to pesticide measurements in water • 3 comparison tests were performed for a dataset of 1040 measurements from 3 sites • Predictive quality was low to medium for the indicators and acceptable for the model • The model and indicators with medium predictive quality can be recommended for use Stakeholders need operational tools to assess crop protection strategies in regard to environmental impact. The need to assess and report on the impacts of pesticide use on the environment has led to the development of numerous indicators. However, only a few studies have addressed the predictive quality of these indicators. This is mainly due to the limited number of datasets adapted to the comparison of indicator outputs with pesticide measurement. To our knowledge, evaluation of the predictive quality of pesticide indicators in comparison to the quality of water as presented in this article is unprecedented in terms of the number of tested indicators (26 indicators and the MACRO model) and in terms of the size of datasets used (data collected for 4 transfer pathways, 20 active ingredients (a.i.) for a total of 1040 comparison points). Results obtained on a.i. measurements were compared to the indicator outputs, measured by: (i) correlation tests to identify linear relationship, (ii) probability tests comparing measurements with indicator outputs, both classified in 5 classes, and assessing the probability i.e. the percentage of correct estimation and overestimation (iii) by ROC tests estimating the predictive ability against a given threshold. Results showed that the correlation between indicator outputs and the observed transfers are low (r b 0.58). Overall, more complex indicators taking into account the soil, the climatic and the G R A P H I C A L A B S T R A C T a b s t r a c t a r t i c l e i n f o Contents lists available at ScienceDirectScience of the Total Environment j o u r n a l h o m e p a g e : w w w . e l s e v i e r . c o m / l o c a t e / s c i t o t e n v environmental aspects yielded comparatively better results. The numerical simulation model MACRO showed much better results than those for indicators. These results will be used to help stakeholders to appropriately select their indicators, and will provide them with advice for possible use and limits in the interpretation of indicator outputs.

“…[15][16][17] This process allows for minimizing the ohmic drop and then the cell resistance, i. e., the conductivity requirement. Also known as paracetamol, it is a widely prescribed analgesic and anti-pyretic drug that has been detected in groundwater [20] and surface water [21,22] in concentrations up to 65 μg L À 1 . A further advantage is the transfer intensification, which increases the oxygen redox cycle and iron redox cycle in undivided microcells.…”

Advanced Electro‐Oxidation with Boron‐Doped Diamond for Acetaminophen Removal from Real Wastewater in a Microfluidic Reactor: Kinetics and Mass‐Transfer Studies

2019

The removal of hazardous organic micropollutants in municipal wastewater treatment plants (WWTP) has become a common concern for public decision-makers and stakeholders. An advanced electro-oxidation with boron-doped diamond (BDD) anode material is proposed to remove acetaminophen as a representative micropollutant in synthetic solution. A customized microfluidic reactor was run in batch mode, and the main operating parameters (i. e. current density, interelectrode distance and solution conductivity) were optimized by minimizing the energy requirement. An optimal current density of 4 mA cm À 2 and an optimal interelectrode distance of 500 μm were newly obtained and explained. Mass transport limitation was observed at lower gaps, with a 3.4-fold decrease in the mass transfer coefficient from 500 μm to 50 μm intervals. In addition, the kinetics of degradation decreased dramatically after a certain electrolysis time. This was attributed to the increase in gas bubble production with treatment time. An increase in the solution conductivity from 0.23 to 2.0 mS cm À 1 increased the degradation rate efficiency twofold and decreased the specific energy from 0.88 to 0.17 kWh g À 1 at 85 % acetaminophen decay yield. The influence of a real matrix from low-conductivity reclaimed WWTP (0.86 mS cm À 1 ) highlighted slightly lower kinetics of degradation, but similar energy efficiency until 60 % of pollutant degradation and higher energy efficiency than in conventional macro-reactors.[a] Dr. E.
