TL;DR: In this paper, a method for detecting 153 pesticide residues in a heart benefiting and pulse restoring particle was proposed, which is a liquid chromatography-mass spectrometry (LCMS) method.
Abstract: The invention relates to a method for detecting 153 pesticide residues in a heart benefiting and pulse restoring particle. The method is a liquid chromatography-mass spectrometry method. The method comprises the following steps: preparing a sample solution, preparing a matrix mixed reference substance working solution, and detecting the solutions through using the high performance liquid chromatography-mass spectrometry, wherein the sample solution is prepared through the following steps: crushing the heart benefiting and pulse restoring particle, weighing 1.8-2.2 g of the heart benefiting and pulse restoring particle, adding 80-120 [mu]L of an internal standard solution with the concentration of 5 [mu]g/mL, adding 8-12 mL of water, infiltrating the particle for 28-32 min, adding 8-12 mL of an acetonitrile solution containing 0.08-0.12% of acetic acid, oscillating the obtained solution in a swirl mixing oscillator at a rate of 4000-6000 r/min for 1.8-2.2 min, adding 3-5 g of anhydrous magnesium sulfate and 0.08-1.2 g of sodium acetate, carrying out swirl shaking for 4-6 min, centrifuging the obtained solution at a speed of 4000-6000 r/min for 4-6 min, taking 0.8-1.2 mL of the obtained supernatant, adding the supernatant to a centrifuging tube which is filled with 140-460 mg of anhydrous sodium sulfate, 23-27 mg of PSA, 48-52 mg of C18 and 2.3-2.7 mg of GCB in advance, carrying out swirl shaking for 2-4 min, centrifuging the obtained solution at a rate of 4000-6000 r/min for 4-6 min, taking the obtained supernatant, and filtering the supernatant by a 0.2-0.24 [mu]m filter membrane.

TL;DR: In this article, the authors summarized and explained the available analytical and advanced methods for determination of pesticides compound in environment and foodstuffs, also, pesticides classification and its toxicity, and available extraction methods are briefly discussed.
Abstract: Pesticides are widely applied to prevent unwanted pests from attacking crops and livestock which led to their access into the environment. Overuses of pesticides in environment are presence of pesticide residues and their metabolites that are causing serious detrimental effects on human health and all other living organisms. Several severe diseases (Cancer, chronic obstructive pulmonary disease, birth defects, infertility) and more damages of human health are associated with the exposure of pesticides. The maximum residue limits for pesticides have been regulated by the Codex Alimentarius Commission and European Union to protect human health. Thus, monitoring these compounds is extremely important to ensure that only permitted levels of pesticide are consumed. To date, several techniques have been developed for pesticide detection, from conventional analytical to advanced detection techniques. The conventional analytical methods are gas chromatography and high performance liquid chromatography coupled with various detectors involved a sample preparation step prior to further analysis. Advanced detection methods refer to the sensors development such as electrochemical, optical, piezoelectric and molecular imprinted polymer. In this review, we summarized and explained the available analytical and advanced methods for determination of pesticides compound in environment and foodstuffs. Also, pesticides classification and its toxicity, and available extraction methods are briefly discussed.

TL;DR: All reported chromatographic methods for the detection and quantification of CBZ in food are reviewed for the first time and the matrices, extraction procedures, and separation and detection parameters are compared to provide new insights on the development of new reliable methods.
Abstract: Carbendazim (CBZ), which is a fungicide widely used for the management of plant diseases, has been detected in a number of food products. The negative effects of CBZ to human health have stimulated the reduction of the maximum residue limits (MRLs), and subsequently the development of reliable and sensitive detection methods. Here, we are reviewing for the first time all reported chromatographic methods for the detection and quantification of CBZ in food. Several techniques, including liquid chromatography (LC), thin layer chromatography (TLC), micellar electrokinetic chromatography (MEKC), and supercritical fluid chromatography (SFC), were used for the separation and detection of CBZ, showing diverse characteristics and sensitivity. Some methods allowed the specific determination of CBZ, whereas other methods were successfully applied for the simultaneous quantification of a huge number of pesticides. Most reported methods showed limits of detection (LOD) and quantification (LOQ) lower than the MRLs. Relevant efforts in the field have been directed toward the simplification and optimization of the extraction steps prior to the chromatographic separation to increase the recovery and reduce the matrix effects. In this Review, the matrices, extraction procedures, and separation and detection parameters are detailed and compared in order to provide new insights on the development of new reliable methods for the detection of CBZ in food.

TL;DR: In this article, constructed wetlands (CWs) and biopurification systems (BPS) were used to remove terbuthylazine from waters of agricultural origin, and three horizontal subsurface flow (HSF) CW systems were operated continuously for one year; the planted CWs (containing either Phragmites australis or Typha latifolia) were able to remove up to 73.7% and 58.4% of the pesticide, respectively, and exhibited a markedly superior performance compared to the unplanted CW.
