“…2b, the degradation rate of DON increased from 75.34% to 100% when the frequency increased from 140 to 200 Hz. The extra energy dissipated in plasma discharge when the frequency over 200 Hz, which agrees with previous studies 37 . As shown in Fig.…”

Background: Deoxynivalenol (DON) produced during the onset of fusarium head blight not only affects the quality and safety of wheat but also causes serious harm to human and livestock health. However, due to the high stability of DON, it is difficult to eliminate it or reduce it naturally after it has been produced. Cold plasma technology is a non-thermophysical processing technology that has been widely used for microbial inactivation and mycotoxin degradation. In this study, the degradation efficiency of double dielectric barrier discharge (DDBD) cold plasma on DON in aqueous solution and wheat was studied; the structures of degradation products of DON and its pathway were clarified, and the effect of DDBD plasma on wheat quality was evaluated.Results: Double dielectric barrier discharge cold plasma was used for efficient degradation of DON (0.5 ∼ 5 ∼gmLˆ-1) solution and achieved a degradation rate of 98.94% within 25 min under the optimal conditions (voltage 100 V, frequency 200 Hz, duty cycle 80%). Furthermore, 10 degradation products (C

“…Moreover, longer exposure time to the plasma discharge zone is more favorable for generated reactive species to attack pesticide molecules resulting in the higher elimination efficacy of pesticides, which is in agreement with the studies of Sarangapani et al [9]. Finally, a reason for the increased degradation effect as the frequency increased is that a higher frequency delivers more energy input to the plasma reactor increasing the number and average energy of reactive species, enhancing the collision possibility and the competence of reactive species to break chemical bonds of pesticides [26].…”

Plasma is a surface decontamination tool that is widely used in the food fields for pesticide degradation. In this study the effect of plasma on pesticide elimination from the surface of corn and the corn quality changes were tested as functions of power, air flow rate, treatment time, and frequency. Results indicated that plasma treatment for 60 s at 1000 mL·min−1 air flow rate, power of 20 W, and frequency of 1200 Hz, achieved the largest degradation efficiency up to 86.2% for chlorpyrifos and 66.6% for carbaryl, both of which were below the maximum residues limit of grains. Most importantly, after plasma treatment, there was a remarkable decrease (p < 0.05) in moisture content and starch content for treated corn compared with control. The acid value for treated corn showed a prominent increase (p < 0.05), but within the acceptable range of the standard. The vitamin B2 content of treated corn did not show a significant difference (p > 0.05). All results of this study demonstrated that plasma treatment is a promising technology with the ability to remove pesticide residues on corn while maintaining its quality within acceptable limits.

“…The mobility of a pesticide in the soil, especially when applied directly to it, by spraying or chemigation, depends on several factors such as the characteristics of the product itself and the physical and hydraulic properties and characteristics of the soil (Cruciani et al, 1996;Hatzisymeon et al, 2021;Oliveira et al, 2000). Therefore, knowing the transport dynamics of an agrochemical at a soil makes its use more efficient and conscious.…”

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

et al. 2022

View full text Add to dashboard Cite

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).
