“…Some other methods reported in literature, including microwave‐assisted extraction [23], solid‐phase extraction (SPE) [24], quick, easy, cheap, effective, rugged, and safe (QuEChERS) [25], homogeneous liquid–liquid microextraction (HLLME) [26], DLLME [27], and ultrasound‐assisted extraction combined with SPE (UAE‐SPE) [1] were compared with the present method for amide herbicides extraction, and the results are shown in Table 4. It is obvious that there is no significant difference in the recoveries obtained by the methods.…”

A rapid method based on continuous‐flow microwave‐assisted extraction and online single drop microextraction was first developed and applied to the determination of amide herbicides in rice. The present method has the advantages of both continuous‐flow microwave‐assisted extraction and online single drop microextraction, which combines extraction, separation, preconcentration, and sample introduction in one step. By continuous‐flow microwave‐assisted extraction, analytes were first extracted from the rice samples using 15% methanol–water, and then concentrated into single drop. The microdrop was retracted into microsyringe and directly analyzed by gas chromatography with mass spectrometry without any filtration or clean‐up process. The method greatly simplifies the sample treatment procedure, reduces consumption of toxic organic solvent, and extends the application of single drop microextraction to complex solid samples. Several parameters were optimized by Box–Behnken design. Under optimal experimental conditions, good linearity was observed in the range of 2.0–500.0 μg/kg. The limits of detection and quantification were in the range of 0.3–1.5 and 1.1–5.1 μg/kg, respectively. The intra‐ and inter‐day precisions were between 1.9 and 4.8%. The present method was used to the analysis of real rice samples, and the recoveries of analytes were between 80.3 and 102.3% with the relative standard deviations ranging from 1.1 to 6.9%.

“…There are some different analytical methods for detecting herbicide residues in the environment. High performance liquid chromatography (HPLC) [68,69], gas chromatography (GC) [70], thin-layer chromatography (TLC) [71], high performance liquid chromatography/mass spectrometry (HPLC-MS) [72], gas chromatography/mass spectrometry (GC-MS) [73], high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) [74], and capillary electrophoresis [75] are from essential and commonly used analytical methods herbicide residues evaluating studies in soil. Successful detection of herbicide residues from different media has been reported using analytical methods [76,77].…”

Environmental pollution is one of the most critical issues concerning the quality of the environment and threatens the human safety due to bioaccumulation. The extensive application of pesticides causes great public concern about the negative impacts on the environment and human health. Herbicides have been used for weed management and to prevent the yield loss of agricultural products. In recent years, the environment's quality is extensively considered due to the enormous pesticide application in agroecosystems. There are some different pathways for the degradation of herbicides in the environment, including biodegradation, chemical degradation, photodegradation, uptake by target or non-target plants, adsorption to soil particles and leaching. Assessing the environmental risks of herbicides before mass production, commercialization, and distribution is very important. The presence of herbicide residues in the environment has become a fundamental problem in many countries. Bioassay and analytical methods could identify, detect, and quantify herbicide residues in the environment. In this review paper, the fate, detection methods, and effect of herbicides on non-target plants have been discussed.

“…It is therefore critical to sensitively detect and clear the alachlor from the environment. Traditional removal methods include adsorption, coagulation, sedimentation, filtration, and chemical and membrane technologies. − Many common detection methods had focused largely on gas chromatography (GC), high-performance liquid chromatography (HPLC), and sensing . The technologies emerging in endless sensing and adsorption have been recently considered as promising techniques because they may not require specialized laboratories and professionals to perform in practical applications.…”

Excessive use of pesticides has brought about serious environmental risks worldwide that pose significant harm for human health. Herein, a series of metal–organic framework (MOF)-based gel capsules with a pitaya-like core–shell structure are constructed through a green polymerization strategy for pesticide detection and removal, namely ZIF-8/M-dbia/SA (M = Zn, Cd). Significantly, the ZIF-8/Zn-dbia/SA capsule exhibits sensitive detection of alachlor, a representative pre-emergence acetanilide pesticide, with a satisfactory detection limit of 0.23 μM. In addition, the MOF-based gel capsules can be extended to a universal visual platform for the noninvasive detection of pesticide residues with various MOFs, such as Eu-MOF, Tb-MOF, and Cu-MOF, and participating dye. Similar to pitaya, the ordered porous structure of MOF in ZIF-8/Zn-dbia/SA capsules offers cavity and open sites for removing pesticide from water with the maximum adsorption amount q max of 61.1 mg·g–1 toward alachlor in a Langmuir model. Thereby, this work presents the universality of gel capsule self-assembly technologies, including the well-preserved visible fluorescence area and porosity of the different structurally diverse MOFs, offering an ideal strategy for water decontamination and food safety control fields.
