The 2021 European Union report on pesticide residues in food

EFSA Journal, Volume 21, Issue 4, April 2023., 2023
Abstract Under European Union legislation (Article 32, Regulation (EC) No 396/2005), EFSA is to provide an annual report assessing the pesticide residue levels in foods on the European market. In 2021, 96.1% of the overall 87,863 samples analysed fell below the maximum residue level (MRL), 3.9% exceeded this level, of which 2.5% were non‐compliant, i.e.

Muscarinic acetylcholine receptor activation synergizes the knockdown and toxicity of GABA‐gated chloride channel insecticides

Pest Management Science, Volume 78, Issue 11, Page 4599-4607, November 2022., 2022
Activation of muscarinic acetylcholine receptors in conjunction with gamma‐amino butyric acid inhibiting insecticides results in enhanced knockdown and mortality. Target‐site synergism within the insect nervous system may play a role in insect pest management with the development of selective and effective chemistries.

Pesticide trends in a tailwater recovery system in the Mississippi Delta

Agrosystems, Geosciences &Environment, Volume 5, Issue 4, 2022., 2022
Abstract Tailwater recovery (TWR) systems are an important best management practice (BMP) used to address both water quality and quantity issues in the Mississippi Delta region. Tailwater recovery systems are surface water capture‐and‐irrigation reuse systems using a combination of ditches to capture surface water, an on‐farm storage (OFS) reservoir to

Rapid Screening of 352 Pesticide Residues in Chrysanthemum Flower by Gas Chromatography Coupled to Quadrupole‐Orbitrap Mass Spectrometry with Sin‐QuEChERS Nanocolumn Extraction

Journal of Analytical Methods in Chemistry, Volume 2022, Issue 1, 2022., 2022
To analyze pesticide residues, GC coupled with quadrupole‐Orbitrap MS (GC‐Orbitrap‐MS) has become a powerful tool because of its unique characteristics of accurate mass full‐spectrum acquisition, high resolution, fast acquisition rates, and overcoming matrix interference. This paper presents an efficiency evaluation of GC‐Orbitrap‐MS for identification

Removing Disturbing Matrix Constituents from Biota Extracts from Total Extraction and Silicone‐Based Passive Sampling

Environmental Toxicology and Chemistry, Volume 40, Issue 10, Page 2693-2704, October 2021., 2021
Abstract Contaminant analysis in biota extracts can be hampered by matrix interferences caused by, for example, co‐extracted lipids that compromise the quality of the analytical data and require frequent maintenance of the analytical instruments. In the present study, using gas chromatography coupled to high resolution mass spectrometry (GC‐HRMS), we ...
