“…Pesticide removal from agricultural runoff or drain is vital for the protection of the aquatic ecosystem, and environment. CWs have great potential for pesticide removal from wastewater containing agricultural runoff, and stormwater (Ignatowicz et al, 2020; Lv et al, 2017; Tournebize et al, 2017). Several processes, such as adsorption, hydrolysis, microbial degradation, sedimentation, photolysis, and plant uptake play an important role in the removal of pesticides in CWs (Vymazal & Březinová, 2015).…”

“…The design of CWs and the type of macrophyte species further influence the pesticide removal processes. In one such study, the CWs were found to remove 99.8% of the mixture of eight pesticides using Phragmites australis from domestic wastewater (Ignatowicz et al, 2020). On the basis of review, Tournebize et al (2017) stated that 1% of the total agricultural land or watershed if used as CWs, can potentially reduce >50% of pesticides from the drained watersheds.…”

Constructed wetland systems (CWs) are biologically and physically engineered systems to mimic the natural wetlands which can potentially treat the wastewater from the various point and nonpoint sources of pollution. The present study aims to review the various mechanisms involved in the different types of CWs for wastewater treatment and to elucidate their role in the effective functioning of the CWs. Several physical, chemical, and biological processes substantially influence the pollutant removal efficiency of CWs. Plants species Phragmites australis, Typha latifolia, and Typha angustifolia are most widely used in CWs. The rate of nitrogen (N) removal is significantly affected by emergent vegetation cover and type of CWs. Hybrid CWs (HCWS) removal efficiency for nutrients, metals, pesticides, and other pollutants is higher than a single constructed wetland. The contaminant removal efficiency of the vertical subsurface flow constructed wetlands (VSSFCW) commonly used for the treatment of domestic and municipal wastewater ranges between 31% and 99%. Biochar/zeolite addition as substrate material further enhances the wastewater treatment of CWs. Innovative components (substrate materials, plant species) and factors (design parameters, climatic conditions) sustaining the long‐term sink of the pollutants, such as nutrients and heavy metals in the CWs should be further investigated in the future. Practitioner points Constructed wetland systems (CWs) are efficient natural treatment system for on‐site contaminants removal from wastewater. Denitrification, nitrification, microbial and plant uptake, sedimentation and adsorption are crucial pollutant removal mechanisms. Phragmites australis, Typha latifolia, and Typha angustifolia are widely used emergent plants in constructed wetlands. Hydraulic retention time (HRT), water flow regimes, substrate, plant, and microbial biomass substantially affect CWs treatment performance.

“…Sewage is discharged by 66% of water users, 40% of whom discharge contaminated wastewater [Shakhman et al, 2017;Lykhovyd et al, 2018;Bashynska, 2018;Mitryasova et al, 2021;Shakhman and Bystrintseva, 2021]. The Black Sea river basin covers about 60% of the area of all river basins in the region and currently the Regional office of water resources monitor the water bodies condition, assesses irrigated lands, agricultural lands and settlements that are flooded, as well as hydrochemical and radiological control of border water bodies by agreement between the governments of neighboring countries [Farrelly and Brown, 2011;Vlasov and Hryshchankava, 2014;Ignatowicz, 2020].…”

On the basis of the analysis of wide temporal monitoring data, a forecast of the integrated hydrochemical indicators of the waters of the Inhul river (Ukraine) was carried out. The performed analysis was also the basis for the determination of a mathematical model of natural fluctuations of the indicators studied. The determined sinusoidal dependence of the integrated water quality indicators allowed determining the average time of fluctuations concerning the processes of self-organisation of river waters. In practice, the developed mathematical models may constitute a valuable support and supplement to the existing models in the field of prediction of self-organization processes of river waters. They may also contribute to even more effective minimization of undesirable effects of anthropogenic impact on aquatic ecosystems.

“…Water resource is affected due to the different means of transport of these pesticides such as direct application to water bodies (Schreiner et al 2021), landslides (Butkovskyi et al 2021), or washing of spraying equipment (Becerra et al 2020a;Manasa & Mehta 2020), which are generated as wastewater with pesticides contents (WWPC's), and trigger a series of effects to the environment, human health and living organisms (Van Lexmond et al 2015;Elfikrie et al 2020;Malakootian et al 2020). The main characteristics of these pollutants are related to high toxicity, slow degradation processes, high COD concentrations, and low removal in conventional biological treatments (Ignatowicz 2020;Ge et al 2021;Sarker et al 2021;Yu et al 2021).…”

This article had the one and only objective of consolidating the couplings of advanced oxidation processes and biological in the decontamination of wastewater with pesticide content reported in the Scopus and Web of Science databases, through a critical analysis of which have been the most used, what methodologies have been implemented to develop them, identify the objectives of each work, determine the success of the research and where the main niches of knowledge are, which can lead to the generation of new scientific knowledge as well as future trends. A co-occurrence analysis was carried out through the VOSViewer software, to determine the most associated key words with the treatment configurations described above. Fenton and Photo-Fenton processes, heterogeneous photocatalysis TiO2/UV, electrocatalysis, ozonization and a particular case of hydrodynamic-ozone cavitation as main advanced oxidation processes, together with advanced biological processes such as SBR, MBR, MBBR; biodegradability and toxicity tests with bacterial strains and surface wetlands, whose treatment philosophy is activated sludge. The main future trends are the reuse of treated wastewater, the analysis and control of costs towards the efficient use of resources and the primary study of the byproducts generated in advanced oxidation to improve the efficiencies in the coupling.
