“…Moreover, acetonitrile or methanol coupled with distilled water is commonly used as the LC mobile phase. Fortified buffers, such as ammonium formate and formic acid, are used to improve the shape of chromatographic peaks (Gan et al, ). Hence, (a) 0.1% formic acid in distilled water, (b) 5 m m ammonium formate in distilled water, (c) 10 m m ammonium formate in distilled water and (d) 0.1% formic acid with 10 m m ammonium formate in distilled water were assessed as aqueous phases (mobile phase A), and acetonitrile and methanol were tested as the organic phase (mobile phase B).…”

“…It is therefore incorporated with pyrethrins (pyrethroids), rotenone and carbamates in food and nonfood crops, products targeting termites and mosquitoes and veterinary pesticides, to enhance their properties. As modern agricultural practices are largely dominated by the frequent application of pesticides, the environmental impacts of these formulations have received much attention (Gan et al, ). For instance, laying hens fed piperonyl butoxide for several days may produce eggs containing residual piperonyl butoxide (Hallman, Bond, Buhl, & Jenkins, ).…”

“…Several extraction methodologies, including solid‐phase extraction (SPE), gel permeation chromatography, solid‐phase microextraction (Gan et al, ) and dispersive solid‐phase extraction (d‐SPE), have been tested for the elimination of proteins, lipids, and other interfering components from various animal products during residue analysis. Among these methods, quick, easy, cheap, effective, rugged, safe (QuEChERS) method is the most widely used sample preparation technique for vegetables and fruits (Lehotay et al, ).…”

Pesticides, which are used as plant protection products, can enter the food chain, and exposure to these xenobiotics can cause a wide array of health problems in humans.Therefore, the objective of the present study was to develop an analytical method for the simultaneous determination of residual spinosad (sum of spinosyn A and D), temephos and piperonyl butoxide in porcine muscle, egg, milk, eel, flatfish and shrimp (sampling period: February to June 2018) using liquid chromatography-triple quadrupole tandem mass spectrometry (LC-MS/MS). The target analytes were extracted with a combination of acidified acetonitrile and ethyl acetate and subsequently purified with original QuEChERS kits (composed of magnesium sulfate and sodium chloride) as well as n-hexane. All analytes were separated on a reversed-phase analytical column using a mobile phase of (A) 0.1% formic acid containing 10 mM ammonium formate in distilled water and (B) methanol. Good linearity (R 2 ≥ 0.980) was achieved over the tested concentration range (3.5-35 μg/kg for spinosyn A; 1.5-15 μg/kg for spinosyn D; 5-50 μg/kg for temephos and piperonyl butoxide) in matrix-matched standard calibrations. Fortified samples at three spiking levels yielded recoveries in the range of 71-105% with relative standard deviations ≤9.2%. The applicability of the method was evaluated via evaluating samples collected from a large wholesale market located in Seoul, and none of the samples contained any of the target analytes.In conclusion, the current approach is simple, efficient and reliable and can successfully determine the residual levels of spinosad, temephos and piperonyl butoxide in complex animal-derived food products.

“…In analysis of pesticide residues, major progress in recent years was the introduction of GC-MS/MS and LC-MS/MS. They can significantly increase the analyzing speed and identify more than one hundred of pesticides compared to previous GC or LC methods, and have been widely used to analyze multiple pesticide residues in various matrices, such as water [8,9], animal tissues [10][11][12], plants and plant oils [13][14][15][16], and teas [17,18]. When operated in multiple reaction monitoring (MRM) mode, improved sensitivity and excellent selectivity can be achieved.…”

In this work, gas chromatography tandem with electron ionization and full-scan high-resolution mass spectrometry with a time-of-flight mass analyzer was evaluated for analyzing pesticide residues in teas. The relevant aspects for mass spectrometry analysis, including the resolution and mass accuracy, acquisition rate, temperature of ion source, were investigated. Under acquisition condition in 2-GHz extended dynamic range mode, accurate mass spectral library including 184 gas chromatography detectable pesticides was established and retrieval parameters were optimized.The mass spectra were consistent over a wide concentration range (three orders) with good match values to those of NIST (EI-quadrupole). The methodology was verified by the validation of 184 pesticides in four tea matrices. A wide linear range (1-1000 μg/kg) was obtained for most compounds in four matrices. Limit of detection, limit of quantification, and limit of identification values acquired in this study could satisfy the requirements for maximum residue levels prescribed by the European Community. Recovery studies were performed at three concentrations (10, 50, and 100 μg/kg). Most of the analytes were recovered at an acceptable range of 70-120% with relative standard deviations ≤ 20% in four matrices. The potential extension of qualitative screening scope makes gas chromatography tandem with electron ionization and mass spectrometry with a time-of-flight mass analyzer a more powerful tool compared with gas chromatography with tandem mass spectrometry.

“…This method involves extraction with methanol/water or acetonitrile/water mixtures and can achieve limits of quantification (LOQ) as low as 10 µg kg −1 . 7 Lately, a few multiresidue methods that include the analysis of fluxapyroxad in foodstuffs have been developed, [9][10][11][12] and alternative approaches using gas-chromatography have also been reported. 13 Moreover, our research group recently reported the generation of polyclonal antibodies specific of fluxapyroxad.…”
