“…This method has proved to be efficiently to extract organic and inorganic compounds in environmental samples. 23,24 However, the experimental temperature was greatly restricted by the melting point of the available organic extractant. Therefore, we need to search some new extractant to enlarge the application range of the DLLME-SFOD.…”

“…It can be rapidly solidified at temperature below its melting point (usually10–30°C) for convenient phase separation. Stirring‐assisted , vortex‐assisted , ultrasonic‐assisted , and air‐assisted agitation have been used for promoting the efficiency of extraction. The solidified organic droplet is collected into a conical vial and melted at room temperature.…”

Liquid microextraction employing solidification of the floating organic droplet, with vortexing and heating to optimize extraction efficiency, was developed for the determination of seven insecticides in fruit juice, vegetables, and agricultural runoff water. The extracts were analyzed by gas chromatography with both flame ionization and mass spectrometry detection for the determination of chlorpyrifos, prothiofos, profenofos, ethion, λ-cyhalothrin, permethrin, and cypermethrin, respectively. Using 20 μL of 1-undecanol in 10 mL of aqueous solution containing 1% w/v sodium chloride provided preconcentration factor of 500. The enrichment factor of the analytes was in the range of 355 to 509 with extraction recovery >71%. The linearity ranges were 4-200 μg/kg for gas chromatography with flame ionization detection and 1-100 μg/kg for gas chromatography with mass spectrometry, with limits of detection ranging from 0.04 to 1.2 μg/kg, which are lower than the international maximum residue limits for vegetables and fruit juice. Intra-day and inter-day precisions are less than 5.4 and 7.0% relative standard deviation, respectively. The method was successfully applied to the determination of the seven insecticides in samples of vegetables, fruit juice and agricultural runoff, with recoveries ranging from 61.7 to 120.8%. The extraction method is simple, efficient and environmentally friendly.

“…Up to now, the residue of picoxystrobin has been concentrated in analytical methods in different matrices, including crops (Walorczyk et al 2015;Mercader et al 2012;Guan et al 2013;Hiemstra and Kok 2007;Cunha and Fernandes 2011), baby foods (Viñas et al 2009), fruits and vegetables (Lacina et al 2010;Guan et al 2014;Melo et al 2012;Campillo et al 2010), fruit juice (Liang et al 2013;You et al 2015), honeybees (Walorczyk and Gnusowski 2009), beer (Esteve-Turrillas et al 2010), and chrysanthemum (Xue et al 2015). In these studies, gas chromatography-mass spectrometry (GC-MS) was the most commonly used instrument (Bartlett et al 2002;Walorczyk et al 2015;Cunha and Fernandes 2011;Melo et al 2012;You et al 2015). Gas chromatography-electron capture detector (GC-ECD) (Liang et al 2013;Esteve-Turrillas et al 2010), high-performance liquid chromatography (Campillo et al 2010;Liang et al 2013), ultra performance liquid chromatography/time of flight mass spectrometry (UPLC-TOF-MS) (Lacina et al 2010) have also been introduced in the analysis of picoxystrobin.…”

A simple, rapid and efficient method for the determination of picoxystrobin in watermelon ecosystem was established and validated via QuEChERS (quick, easy cheap, effective, rugged and safe) method using rapid resolution liquid chromatography tandem mass spectrometry (RRLC-MS/MS). The average recoveries (n=5) of picoxystrobin in three matrix at three fortification levels ranged from 89.4% to 102.6%. The limits of detection (LODs) were lower than 1.28×10 _ 4 mg L _ 1. The limits of quantification (LOQs) were 0.001 mg kg _ 1 for watermelon flesh (whole watermelon) and 0.005 mg kg _ 1 for soil. The half-life of picoxystrobin of whole watermelon (soil) in Shandong and Anhui were 1.43 (4.18) days and 3.71 (17.32) days, respectively. The picoxystrobin terminal residues in watermelon were lower than 0.001 mg kg _ 1 under the recommended dosages, which were far below the maximum residue limit (MRL) set by China (0.05 mg kg _ 1). These obtained data not only provide scientific information about safety estimation of picoxystrobin in watermelon and the kinetics of dissipation, but also facilitate trade exportation of watermelon for China.
