“…Concentration in lakes reached 86.7 ng/L for carbendazim and 49.3 ng/L for triazines, while in rivers triazines content increased to 164 ng/L. Furthermore, lower contamination was observed for drinking water with respect to freshwater with total pesticide concentrations of 39.3 ng/L and 3.54 ng/L found in tap water and bottled water respectively [39]. Very different concentration levels were instead observed for parabens in distinct water sources, in particular mg/L in the influents of WWTPs, µg/L in their effluents, and ng/L in drinking water [91].…”

“…OPPs are widely employed in agriculture (e.g., chlorpyrifos with 45,000 tons produced in 2016) and their residues in all food products and related environments need to be estimated in order to assess the risks of human exposure [38]. Atrazine is one of the most popular CTs herbicides used for many years and, together with other dangerous EDCs (equally banned in most countries) is again detected in surface and underground water all over the world [39]. Although the use of synthetic pesticides in agriculture has helped to increase food production, there is a great cost to human health, the environment, and its resources.…”

Endocrine-disrupting compounds (EDCs) as emerging contaminants have accumulated in the aquatic environment at concentration levels that have been determined to be significant to humans and animals. Several compounds belong to this family, from natural substances (hormones such as estrone, 17β-estradiol, and estriol) to synthetic chemicals, especially pesticides, pharmaceuticals, and plastic-derived compounds (phthalates, bisphenol A). In this review, we discuss recent works regarding EDC occurrence in the aquatic compartment, strengths and limitations of current analytical methods used for their detection, treatment technologies for their removal from water, and the health issues that they can trigger in humans. Nowadays, many EDCs have been identified in significant amounts in different water matrices including drinking water, thus increasing the possibility of entering the food chain. Several studies correlate human exposure to high concentrations of EDCs with serious effects such as infertility, thyroid dysfunction, early puberty, endometriosis, diabetes, and obesity. Although our intention is not to explain all disorders related to EDCs exposure, this review aims to guide future research towards a deeper knowledge of EDCs’ contamination and accumulation in water, highlighting their toxicity and exposure risks to humans.

“…The mean concentrations of azoxystrobin, hexaconazole, aldicarb-sulfone, and acetamiprid were 32.52, 30.73, 5.62, and 4.67 ng/L, respectively (Table S6). These micro-pollutants have been detected in the stream water of agricultural areas because they can be used for herbicides, insecticides, and fungicides globally (Bermúdez-Couso et al, 2013;Berny's et al, 2019;Chau et al, 2015;Hwang et al, 2019;Muhammetoglu et al, 2019;Wan et al, 2021). Among the six micro-pollutants, acetamiprid, azoxystrobin, and hexaconazole showed higher concentrations during the wet season.…”

In recent years, as agricultural activities and types of crops have become diverse, the occurrence of micro-pollutants has been reported more frequently in rural areas. These pollutants have detrimental effects on human health and ecological systems; thus, it is important to manage and monitor their presence in the environment. The modeling approach could be an effective way to understand and manage these pollutants. This study predicts the concentrations of micro-pollutants (MPs) using deep learning (DL) models, and the results are then compared with simulation results obtained from the soil water assessment tool (SWAT) model. The SWAT model showed an unacceptable performance owing to the resulting negative NasheSutcliffe efficiency (NSE) values for the simulations. This may be caused by the limitations of SWAT, which pertains to adopting simplified equations to simulate micro-pollutants. In addition, the ambiguous plan of pesticide application increased the model uncertainty, thereby deteriorating the model result. Here, we developed two different DL models: long short-term memory (LSTM) and convolutional neural network (CNN). LSTM exhibited the highest model performance, with NSE values of 0.99 and 0.75 for the training and validation steps, respectively. In the multi-target MP model, the error decreased as the number of simulated pollutants increased. The simulation of the four pollutants had the highest error, while the six-target simulation had the lowest error. In conclusion, this study demonstrated that the LSTM model has the potential to improve the prediction of MPs in aquatic systems.

“…Triazine herbicides have been widely used for weed control of several crops and are classified as persistent organic compounds since they resist biological and chemical degradation. In spite of the ban on the use of atrazine (ATZ) by the European Union in 2004 [23], triazines are still the most frequently detected pesticides in environmental waters [24,25]. In fact, it is still used in several non-European countries or just replaced by terbuthylazine (TER), and thus, both herbicides are included in the list of priority substances in the field of water policy [26].…”

In this work, the preparation and evaluation of water‐compatible molecularly imprinted polymers for triazines using 2‐hydroxyethyl methacrylate and methacrylic acid as comonomers is described. Four sets of molecularly imprinted and non‐imprinted polymers for propazine were prepared at varying monomer molar ratios (from 4:0 to 1:3), and evaluated for the recognition of several triazines directly in aqueous media. The evaluation was performed by loading 1 mL of an aqueous solution containing 500 ng of each selected triazine, washing with 500 μL of acetonitrile, and eluting with 500 μL of methanol followed by 2 × 500 μL of a solution of methanol containing 10% of acetic acid. Final determinations were performed by high‐performance liquid chromatography‐ultraviolet detection. Improvement in molecular recognition of triazines in water was obtained on those molecularly imprinted polymers incorporating 2‐hydroxyethyl methacrylate in 3:1 or 2:2 molar ratios, being the former selected as optimum providing recoveries for propazine up to 80%. A molecularly imprinted solid‐phase extraction protocol was developed to ensure that triazines‐selective recognition takes place inside selective binding sites in pure water media. Finally, the developed method was successfully applied to the determination of the selected triazines in environmental waters providing limits of detection from 0.16 and the 0.5 μg/L concentration range.
