Detection of pesticides in crops: A modified QuEChERS approach

Untitled

“…Rugged and Safe), developed by Anastassiades et al (2003) in order to analyze veterinary drugs, is used nowadays due to its high potential to adapt to analysis of pesticide residues in both agricultural and animal products and has been widely accepted by the international community for the analysis of pesticide residues in different foods. Some of the food matrixes in which it has been demonstrated to be successful for pesticide extraction are: avocado (Benavides & Echeverría, 2014), rice (Hou et al, 2013), shrimp (Omar et al, 2013), peach (Pinho Costa et al, 2014), cocoa grains (Dankyi et al, 2015), orange juice (Rizzetti et al, 2016), olive oil (García-Reyes et al, 2007), tamarind (Paz et al, 2015), corn and soy (Marchis et al, 2012).…”

A multiresidue screen for the analysis of toxicants in bovine rumen contents

“…In cases utilizing wide-scope screening, it is important that the method used to clean up the sample retains the toxicants to confirm its presence or absence in the submitted sample. A number of articles have been published that describe general screening methods for the analysis of pesticides in feed using GC-MS. [1][2][3]5,7,9,[11][12][13] However, the typical bovine diet of grain, hay, silage, and mineral supplements results in the presence of a complex mixture of digested and undigested feed components and chemical residues in the rumen contents. The methods developed for feed materials for grain cannot be assumed to be also suitable for rumen contents.…”

Current Trends in Sample Treatment Techniques for Environmental and Food Analysis

“…This last step is performed by adding small amounts of bulk SPE packing sorbents to the extract. This procedure has attracted the attention of pesticides laboratories worldwide and it is the most commonly employed sample treatment methodology for the multi-residue analysis of pesticides in fruits and vegetables [9,10,[76][77][78][79][80]. But today, this methodology is not limited to the analysis of pesticides and its use for the extraction of other families of compounds is tremendously increasing.…”
