“…As an effective new herbicide, the fate of flumioxazin in water, soil, and plants has received widespread attention (Ando et al, 2017; Chen et al, 2021). Our study has theoretically demonstrated the potential health threat of flumioxazin to aquatic organisms.…”

Flumioxazin is a widely applicated herbicide in the control of aquatic plants. Current evidence suggested that flumioxazin could induce cardiac defects (ventricular septal defects) in vertebrates, but the underlining mechanisms remain unclear. Because of the inhibitory effect of flumioxazin on polyphenol oxidase (PPO), the assumption is made that flumioxazin‐induced cardiotoxicity is caused by oxidative stress. The results show that flumioxazin induced cardiac malformations and abnormal gene expression associated with cardiac development. Cardiac malformations include pericardium edema, cardiac linearization, elongated heart, cardiomegaly, cardiac wall hypocellularity, myocardial cell atrophy into granular, and a significant gap between the myocardial intima and the adventitia. An increase in oxidative stress and apoptosis was observed in the cardiac region of zebrafish after exposure to flumioxazin. Antioxidant astaxanthin reversed the cardiac malformations, excessive ROS production and expression of genes for cardiac developmental and apoptosis regulation induced by flumioxazin. In addition, flumioxazin also activated AHR signaling pathway genes (ahr2, cyp1a1, and cyp1b1) and increased porphyrins concentration. In conclusion, the results suggest that excessive ROS production, which could be mediated through AHR, led to apoptosis, contributing to the cardiotoxicity of flumioxazin in zebrafish embryos.

“…It can kill weeds by inhibiting the activity of protoporphyrinogen oxidase (PPO) (Ando et al., 2017; Asher et al., 2020; Eason et al., 2022; Wang, Li, et al., 2017; Wang, Zhang, et al., 2019). The half‐life of Flu in soil is approximately 15 days (Chen et al., 2021). Even small amounts of residues have adverse side effects due to toxicity, such as those on soil and the internal structure of crops (Nageswara Rao et al., 2021).…”

In this study, an excellent monoclonal antibody (mAb) was produced that could sensitively and specifically recognize Flu in fruit samples. The mAb belonged to the IgG2 subclass and had a half-inhibitory concentration (IC 50 ) of 0.59 ng/ml and a limit of detection (LOD) of 0.13 ng/ml. A cross-reactivity test revealed that the mAb had good specificity for Flu. A gold nanoparticle-based lateralflow immunochromatographic (ICA) strip was used for the rapid screening of Flu in fruit samples. The method had a visual cut-off value of 10 µg/kg for Flu in three different fruit samples when evaluated with the naked eye. The LODs were 5.25, 3.13, and 4.64 µg/kg for Flu in apples, grapes, and oranges, respectively, as obtained with the aid of a strip scan reader. Therefore, this ICA strip assay represented a potential tool for the detection of Flu in fruit samples.

“…Indeed, the harm of weedicide leaching has been frequently reported in groundwater. Several studies have indicated that the leaching risk potential of herbicides to groundwater is positively correlated with its mobility in soil (Chen et al, 2021;Wang et al, 2019;Silva et al, 2019;Kaur et al, 2021;Willett et al, 2020). Guimares et al (2019), who found that hexazinone (herbicide) proved to be a potential contaminant of groundwater and metribuzin (herbicide) presented high leaching in the soil profile.…”

Abstract. E or pyriminobac-methyl (EPM), a pyrimidine benzoic acid esters herbicide, has a high potential as weedicide; nevertheless, its environmental behaviors are still not well understood. In this study, we systematically investigated, for the first time, the adsorption–desorption, degradation, and leaching behaviors of EPM in agricultural soils from five exemplar sites in China (Phaeozems – S1; Anthrosol – S2; Ferralsol – S3; Alisol – S4; Plinthosol – S5) through laboratory simulation experiments. Our results show that the EPM adsorption–desorption results were well fitted by the Freundlich model (R2>0.9999). In the analyzed soils, the Freundlich adsorption (i.e., Kf ads) and desorption (i.e., Kf des) coefficients of EPM varied between 0.85 and 32.22 mg1-1/n L1/n kg−1 and 0.78–5.02 mg1-1/n L1/n kg−1, respectively. The mobility of EPM in soils S1–S5 was categorized as immobile, slightly immobile, highly mobile, slightly mobile, and slightly mobile, respectively. Moreover, the degradation of EPM reflected first-order kinetics, where its half-life ranged between 37.46 and 66.00 d, depending on the environmental conditions, and abiotic degradation was predominant in the degradation of this compound. Overall, the high leaching ability and desorption capacity of EPM were accompanied by a low adsorption capacity, and there were no significant relationships between pH and the leaching rate of EPM in the five types of soils. In contrast, the organic matter content, cation exchange capacity, and soil clay content were the main components responsible for the observed leaching rates. We found that EPM degrades easily, has a high adsorption affinity, and a low mobility in S1, which results in a low contamination risk for groundwater systems. On the contrary, this compound degrades slowly in S2, S3, S4, and S5, due to a low adsorption affinity and moderate mobility, which results in a high contamination risk for groundwater systems. Therefore, our results may serve as a reference for evaluating the risks involved in the increasingly wide application of this compound.
