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

open access: yesPest 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.

Fipronil and fipronil sulfone in chicken: From in vitro experiments to in vivo PBK model predictions

open access: yes, 2022
In 2017 a large-scale fipronil contamination in eggs occurred in several European countries. Fipronil and its metabolites have the potential to be transferred into the eggs of laying hens, thereby entering the human food chain. Here, first the metabolism

Pesticide trends in a tailwater recovery system in the Mississippi Delta

open access: yesAgrosystems, 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

open access: yesJournal 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
