“…Acetochlor, ametryn, asulam, dinoterb and terbutryn were found sporadically and mean concentrations ranged from 5 ng/L to 669 ng/L. Some of these compounds were also detected in various waters in other studies carried out in Italy, Spain, Greece, Germany, France, Switzerland, Denmark, Sweden, USA and China [17,19,20,41,43,53,[55][56][57]. Terbacil was only detected in 2014 with mean concentration of 1135 ng/L.…”

“…However, potential reasons could be their absence on the stores and elimination of stocks. Amitrole and metolachlor were detected in many water samples before [4,7,17,19,20,42,53,54], but tralkoxydim is found in wastewater for the first time in the literature. Acetochlor, ametryn, asulam, dinoterb and terbutryn were found sporadically and mean concentrations ranged from 5 ng/L to 669 ng/L.…”

“…Full-spectrum acquisition techniques could be a solution to this problem. Several research groups used high-resolution mass spectrometry (HRMS) techniques for the investigation of many pesticides and TP/M in different water samples applying target, suspect and non-target screening approaches [15][16][17][18][19][20].…”

Pesticides have been used in large amounts around the world for decades and are responsible for environmental pollution and various adverse effects on human health. Analysis of untreated wastewater can deliver useful information on pesticides’ use in a particular area and allow the assessment of human exposure to certain substances. A wide-scope screening method, based on liquid chromatography coupled to quadrupole-time-of-flight mass spectrometry, was applied, using both target and suspect screening methodologies. Daily composite influent wastewater samples were collected for seven or eight consecutive days in Athens between 2014 and 2020 and analyzed for 756 pesticides, their environmental transformation products and their human metabolites. Forty pesticides were quantified at mean concentrations up to 4.9 µg/L (tralkoxydim). The most abundant class was fungicides followed by herbicides, insect repellents, insecticides and plant growth regulators. In addition, pesticide transformation products and/or metabolites were detected with high frequency, indicating that research should be focused on them. Human exposure was evaluated using the wastewater-based epidemiology (WBE) approach and 3-ethyl-carbamoyl benzoic acid and cis-1,2,3,6-tetrahydrophthalimide were proposed as potential WBE biomarkers. Wastewater analysis revealed the presence of unapproved pesticides and indicated that there is an urgent need to include more transformation products in target databases.

“…Imidacloprid is highly soluble in water, and there is a high possibility of it to enter into aquatic ecosystems through runoff, and thus potentially may pose risks to aquatic organisms, [11–12] such as dropping the survival of invertebrates, [13] inducing cyanobacteria blooms [14] and so on. With its widespread use and its solubility, imidacloprid is commonly detected in rivers all over the world, such as in China, Indian, Span, USA and England [15–20] …”

“…With its widespread use and its solubility, imidacloprid is commonly detected in rivers all over the world, such as in China, Indian, Span, USA and England. [15][16][17][18][19][20] The presence of imidacloprid in water poses a treatment challenge due to its recalcitrance to biodegradation, and its persistence makes it hard to be eliminated through traditional wastewater treatment plants. Imidacloprid has an aerobic and anaerobic half-life of 997 and 27.1 days, respectively.…”

The photocatalytic composites based on BiVO4, TiO2 nanotubes (TNT) and reduced graphene oxide (RGO) were synthesized by a one‐step hydrothermal synthesis method. The properties and structures of the samples were characterized by SEM, XRD, UV‐Vis DRS, Raman spectroscopy, photoluminescence spectroscopy and XPS. The effects of RGO‐TNT loading, pH, and dosage of catalysts on degradation efficiency were tested. The best removal results were occured on the condition that loading amount of RGO‐TNT was 10 %, solution pH 10, and catalyst dosage was 1.4 g L−1. The obtained ternary composite with 10 wt% RGO‐TNT exhibited a significant enhancement in photocatalytic efficiency due to the lower band gap with enhanced light absorption and a suppression in the recombination rates of the photogenerated charge carriers, and about 73 % of imidacloprid was degraded within 30 min under UV irradiation. Furthermore, BiVO4/RGO‐TNT‐10 can be reused for 6 times without obvious catalysis loss. Trapping experiments showed that hydroxyl radicals were the main active species in the imidacloprid photocatalytic degradation, and a possible photocatalytic mechanism was proposed based on the results of trapping experiments.

Ecotoxicological risk assessments form the foundation of regulatory decisions for industrial chemicals used in various sectors. In this study, a multi‐target‐QSAR model established by a backpropagation neural network trained with the Levenberg‐Marquardt (LM) algorithm was used to construct a statistically robust and easily interpretable Mt‐QSAR model with high external predictability for the simultaneous prediction of the environmental fate in form of octanol‐water partition coefficient (LogP), (BCF) and acute oral toxicity in mammals and birds (LD50rat) and (LD50bird) for a wide range of chemical structural classes of insecticides. Principal component analysis was performed on descriptors selected by the SW‐MLR method, and the selected PCs were used for constructing the SW‐MLR‐PCA‐ANN model. The developed well‐trained model (RMSE=0.83, MPE=0.004, CCC=0.82, IIC=0.78, R2=0.69) was statistically robust as indicated by the external validation parameters (RMSE=0.93, MPE=0.008, CCC=0.77, IIC=0.68, R2=0.61). The AD of the developed Mt‐QSAR model was also defined to identify the most reliable predictions. Finally, the missing values in the dataset for the aforementioned targets were predicted using the constructed Mt‐QSAR model. The proposed approach can be used for simultaneous prediction of the environmental fate of new insecticides, especially ones that haven′t been tested yet.
