“…4). Sample preparation methods that have been proposed to date for extraction of neonicotinoids might remain in a complicated sample matrix with lesser quantity for cleaning up, the interfering components that coexist in the sample extract [28]. In the present study, EG variety contained Pyr, Pro, Car, Cyp and Dic pesticide residues with highest concentration of Cyp 16.7±1.38 µg kg -1 followed by Prop 7.425±0.11 µg kg -1 , while other pesticides residues were low and not hazardous to human health (Fig.…”

Protection of agricultural crops from pests and diseases is very important to fulfill the needs of growing population. For this purpose, different types of chemicals are used which leads to the accumulation of toxic organic and inorganic compounds in agricultural cycle particularly in economically important fruits and vegetables. Pesticide residue analysis is fundamentally important to ensure the safety of foods, plant and animal origin, and to preserve the environment. It is therefore crucial to monitor fruits and vegetables for pesticide residues using available advanced analytical techniques. The current study was assigned to investigate pesticide residues in peach fruit. We selected six peach cultivars (Early Grand, Florida King, NJC (05), Elberta (06), Maria Delezia, and Indian blood) from four different locations of district Swat. The sampled fruit varieties were then analysed for pesticide residues using gas chromatography and mass spectroscopy (GC-MS). Results showed that Early Grand variety had pesticide residues with highest concentration of Cypermethrin (16.7±1.38 µg kg -1 ) followed by Pyridaben (7.425±0.11µg kg -1 ). In Florida King, the highest c oncentration of Endosulfan (32.78±0.9 µg kg -1 ) is detected followed by Metachlore (17.36±0.44 µg kg -1 ). In variety NJC and Elberta, Pyredaben, Propachlor, Carbofuran, Cypermethrine, Endosulfan, and Cyhalothrine compound were found. In both varieties, Endosulfan was in the highest concentration (21.27±1.20 µg kg -1 and 67.94±4.61 µg kg -1 respectively). As these two varieties had close harvesting time, both varieties showed a similar pattern of pesticide residues. In variety Maria, Difenaconazole was found in the highest concentration (187.51µg kg -1 ) while the Indian blood variety difenaconazole

“…However, a previous SPE and subsequent dilution of the organic extract could also be considered as a "dilute-and-shoot" approach. The combination of SLE with dSPE, widely known as the QuEChERS approach, has revolutionized the way multiresidue pesticide analyses are carried out [50,61,62]. In general, this sample preparation method consists of an extraction with MeCN, which is caused by partitioning between the aqueous phase of the sample and that of MeCN by adding magnesium sulfate and sodium chloride salts.…”

The extensive use of pesticides represents a risk to human health. Consequently, legal frameworks have been established to ensure food safety, including control programs for pesticide residues. In this context, the performance of analytical methods acquires special relevance. Such methods are expected to be able to determine the largest number of compounds at trace concentration levels in complex food matrices, which represents a great analytical challenge. Technical advances in mass spectrometry (MS) have led to the development of more efficient analytical methods for the determination of pesticides. This review provides an overview of current analytical strategies applied in pesticide analysis, with a special focus on MS methods. Current targeted MS methods allow the simultaneous determination of hundreds of pesticides, whereas non-targeted MS methods are now applicable to the identification of pesticide metabolites and transformation products. New trends in pesticide analysis are also presented, including approaches for the simultaneous determination of pesticide residues and other food contaminants (i.e., mega-methods), or the recent application of techniques such as ion mobility–mass spectrometry (IM–MS) for this purpose.

“…If a flammable organic solvent including acetone is applied as an extraction solvent and a household microwave is utilized to MAE, sparks that may occur within the range can cause a fire or explosion. So, it is necessary to take suitable measures including as preventing the solvent from leaking into the extraction container to minimize fire and explosion danger [28,29].…”

Sample Preparation Techniques for Chemical Analysis

Due to fast growth in microprocessors, analytical instrumentations in spectroscopy, chromatography, microscopy, sensors and microdevices have been subjected to significant developments. Despite these advances, a sample preparation step is indispensable before instrumental analysis. Main reasons are low sensitivity of the instruments, matrix interferences and incompatibility of the sample with the analytical device. Most of the time spent and most of the errors occurring during a chemical analysis is on sample preparation step. As a result, any improvements in this essential process will have a significant effect on shortening the analysis time and its precision and accuracy and lowering the cost. This introductory chapter intends to draw the readers’ attention to the importance of sample preparation, the procedures of sampling and the source of errors that occur in the course of sampling. The chapter then continues with a heading on sample preparation techniques, including exhaustive and non-exhaustive methods of extraction. Microwave, sonication and membrane-based extraction techniques are more emphasized as exhaustive methods and under a new title, miniaturized methods are discussed. Automation, on-line compatibility and simplification is an important aspect of any sample preparation and extraction which is discussed at the end of this chapter.
