“…Due to the simplicity and flexibility of QuEChERS (quick, easy, cheap, effective, rugged and safe)-based sample preparation method [Anastassiades et al, 2003], it serves as a template for modification of multi-residue analysis method [Asensio-Ramos et al, 2010;Koesukwiwat et al, 2010;Gonzalez-Curbelo et al, 2011]. A number of modified versions have been successfully applied for extraction of pesticides from a variety of foods, mainly from fruits and vegetables [Lesueur et al, 2008;Nguyen, 2008;Húšková et al, 2009].…”

Association of official agricultural chemists official method was adapted and used to develop analytical method for determination of 76 pesticides residues in persimmon, grape, and pear by concurrent use of liquid chromatography-tandem mass spectrometry. Despite few exceptions in particular matrix, two fortified spiking (100 and 400 ppb) in three matrices gave satisfactory results in terms of accuracy, repeatability, precision, and linearity. Method detection limits (MDLs) were determined using five low spiking and eight replicate samples. MDLs were calculated by multiplying the standard deviation with student t-value 2.998 for n-1 (7) degree of freedom at 99% confident level. limit of quantification were obtained by multiplying standard deviation with 10. Experimental results indicate grape was the most problematic matrix among tested fruits and persimmon the least. Etoxazole is the most problematic pesticide and not applicable in this method. Developed method was successfully applied for the determination of residual pesticides in blindincurred samples.

“…Hence, acetonitrile was top priority. Previous studies have reported that for the QuEChERS method the addition of water in some dried matrices such as soil samples was recommended to increase the extraction efficiency (Xue et al 2014;Kolberg et al 2011;Zhao et al 2012;González-Curbelo et al 2011;Xu et al 2014). In this study, recoveries of the analytes were at the acceptable range (80-110%) for soil samples after adding 2 mL water in acetonitrile.…”

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.

“…The validity and precision of the method (analytical method efficiency) was determined with recovery tests. The recoveries were calculated based on the peak areas of the analytes, taking into account matrix and dilution effects (Butler et al 2007;Corley 2003;Dankyi et al 2015;González-Curbelo et al 2011;Lesueur et al 2008;Mekonen et al 2014;Nguyen et al 2008;Shrivastava and Gupta 2011). The linearity was determined by preparing a stock solution of pure standards of the pesticides studied and diluting them to produce a concentration range.…”

Pesticides residue analysis in yam from selected markets across Ghana and Belgium: an evaluation of the QUECHERS method

Background: In recent years, concerns have been raised in Ghana regarding the use of pesticides in yamproduction to the extent that it is feared that pesticides residues may be found in the yam tuber which isconsumed by many Ghanaians. This present study, therefore, was designed to assess the level of pesticides residues in yam bought from across Ghanaian markets i.e. production for local consumption and from Belgium grocery shops (export production from Ghana) using the Quick, Easy, Cheap, Efficient, Rugged and Safe (QuEChERS) method coupled with LC-MS/MS. A total of 180 yam samples, including 150 from Ghana and 30 from Belgium were collected and pesticides residues were analyzed using a multi-residue method. Results: A total of 25 pesticides were screened in the yam samples and 11 of them were detected. Theresults indicated that about 46% of the samples contained one or more of the 11 detected pesticides in arange of 0. 000014 mg/kg up to 0.0146 mg/kg. The three most detected pesticides in this study were fenpropimorph, cadusafos and fenitrothion, occurring in 179, 171 and 126 samples respectively. All the detected pesticides were below their respective EU maximum residue limits (MRL). Conclusion: By these results, it can be said that, the residues of the monitored pesticides found in yam arevery low and are unlikely to pose a negative human health effect.
