“…Much more effort is needed to demonstrate the applications of photocatalytic MOFs in removing a wide range of agricultural pollutants. For example, investigations of the efficacy of MOFs for other prevalent or emerging agricultural pollutants such as AMX, norfloxacin, diazinon, and trifluralin are critically needed to enhance our understanding on the capability of MOFs for the removal of agricultural wastes. Due to the complex composition of typical agricultural wastewater, evaluation of the removal efficiency of multiple coexisting trace pollutants and selectivity toward certain pollutants by MOF-based photocatalysts will increase their applications.…”

Increasing demand for food due to rapid population growth has exerted unprecedented pressure on the global agricultural industry. Agrochemicals are widely used to ensure productivity, leading to the prevalence of legacy and emerging agricultural chemicals in the environment, most of which are toxic and persistent. Metal−organic frameworks (MOFs) as a group of novel photocatalytic materials with ultrahigh porosity and tunability have demonstrated high potential for efficient removal of these recalcitrant pollutants. This critical review aims to present the potential of MOF-catalyzed photodegradation of pesticides and antibiotics. Initially, the capabilities of different MOF-based composites to harvest visible light are compared. Examples include MOFs combined with bismuth oxyhalides (BiOX) and graphite oxide (GO). Mechanisms involved in MOF-induced photocatalytic processes such as electron−hole (e − /h + ) separation, generation of reactive species, and degradation pathways of representative pollutants as well as impacts of water chemistry are illustrated in detailed. Research on applying MOF-catalyzed processes is largely in progress, and many more studies with greater mechanistic evaluation are needed to fully assess the potential of such processes to depollute water.

“…Instead of chlorine, its structure incorporates fluorine, and despite the strongly xenobiotic character of some of substituents, biodegradation of trifluralin does occur either by dealkylation or nitro-group reduction. 568 The genes and enzymes responsible for biodegradation are still largely unknown, the relative roles of abiotic processes versus growth-linked biodegradation versus cometabolism are unresolved, and the impact of different environmental factors on the rates and extents of biodegradation are not clear. However, a Candida species gave a certain yield of mineralization even at 14 °C.…”

“…The Trifluralin (α,α,α-trifluoro-2−6-dinitro−NN-dipropylp-toluidine), TFN, is an herbicide of the chemical group Dinitroaniline, widely used in agriculture since 1960 (Coleman et al, 2020;Epp et al, 2018). This pre-emergent herbicide is efficiently used to control grasses and some smallseeded dicotyledonous species (Coleman et al, 2020;Li et al, 2021) and is also capable of minimizing root intrusion in subsurface drippers (Lima, 2011;Mendonça et al, 2020). At a global scale, it is estimated that around 4,400 tons of TFN are currently used per year, mainly for the cultivation of cotton, alfalfa, and soybeans (Maggi et al, 2019).…”

Modeling and simulation of trifluralin herbicide movement due to its application on soils by chemigation

et al. 2022

The Trifluralin (TFN) is a pre-emergent herbicide which is widely used in agriculture. Usually, this pesticide is directly applied to the soil, where it can remain for long periods or can be transported. In this sense, knowing the dynamics of an herbicide soil transport is essential to avoid environmental contamination problems and risks to human health. Thus, this study aims to model and simulate TFN movement on soils with two different textures, a sandy loam and clay loam soil. It was considered that the herbicide was applied via chemigation trough a subsurface drip irrigation system, under a non-steady regime. Therefore, the transport parameters of TFN in these soils and physical-hydric characteristics of these were used, while the physical environment modeling were conducted using the Hydrus 2D software. The results showed that both in sandy and clayey soils, the TFN tends to be retained by the soil, close to where it was applied, not exceeding a layer greater than 2.5 mm outside the dripper radius, even in more favorable conditions such as the presence of irrigation. Finally, it could be concluded that this herbicide movement in the soil is of low potential, due to this product high solid-liquid partition coefficient (Kd), even in sandy soil, which has low cation exchange capacity (CEC).
