Beehive products could be powerful monitors of pesticide residues originating in agroecosystems during production cycles. Their ready availability provides enough samples to perform analytical determinations, but their chemical complexity makes residue analysis a real challenge. Taking advantage the plasticity QuEChERS coupled LC-MS/MS, validated methodologies were developed for bees, honey, beeswax, and pollen applied simultaneous determination 19 most employed pesticides intensive cropping...
Two straightforward methods for glyphosate and AMPA analysis in honey through ion chromatography coupled to Q-Orbitrap accurate high-resolution mass spectrometry as well their application real samples are presented.
Clean-up step is essential during the multiresidue sample preparation process to remove undesired matrix components that may cause analytical interferences or suppression effect. However, its application generally by specific sorbents entails time-consuming work producing low recoveries for some compounds. Moreover, it usually needs be adapted different co-extractives from present in samples using chemical increasing number of validation procedures. Therefore, development a more efficient...
There is an increasing concern about the use of synthetic acaricides to fight ectoparasitic mite Varroa destructor. Natural products such as formic acid (FA) and oxalic (OA) have emerged a possible alternative control strategy. However, given difficulty analysing these highly polar compounds lack robust reliable methods, there are very few studies concentration distribution natural in beehive compartments. We present simple analytical methodology, based on sample extraction with modified...
Chlorpyrifos is one of the most employed insecticides worldwide. It moderately persistent in environment. degrades to 3, 5, 6-trichloro-2-pyridinol (TCP), metabolite toxicological concern both human health and In field, pesticides point contaminations occur during operation application machinery. Biobeds made up a biomixture containing straw, peat, soil have been successfully developed minimise these incidents. The retained are degraded by microorganisms biomixture. Although dissipation...
In this work, three different methods for the extraction of lipids were compared in quinoa seeds: dynamic maceration with hexane, hexane assisted by ultrasound and continuous Soxhlet using an increasing polarity gradient solvents (hexane, ethyl acetate methanol). Method performance was evaluated thorough lipid yield extracts subjected to derivatization generate corresponding fatty acids methyl esters (FAMEs). All obtained fractions (the FAMEs) analyzed thin layer chromatography, showing that...
Honey as a natural food has high quality standard. Nevertheless, honey production is performed together with agricultural activities. Pesticide residues have been detected in samples from various countries including Uruguay, sometimes exceeding their maximum residue limits (MRL). The implementation of modern methodology for the analysis glyphosate presented. sample preparation method named QuPPe, involves extraction methanol and was specifically developed polar pesticides, by ionic liquid...
