AI Article Synopsis
- A green analytical method was developed for extracting and detecting 20 analytes, including 10 neonicotinoid insecticides and their main toxic metabolites, in edible herbs.
- The study utilized QuEChERS and LC-MS/MS, finding residues in 109 herbal samples, with 90 testing positive and total insecticide residues ranging from 0.26 to 139.28 μg/kg.
- Acetamiprid and imidacloprid, along with their metabolites, were the most frequently detected, indicating a need for increased awareness of neonicotinoid insecticide residues in edible herbs.
Article Abstract
In this work, a green analytical method was established for the simultaneous extraction and detection of 20 analytes-10 neonicotinoid insecticides and their 10 major toxic metabolites in edible herbs. QuEChERS and LC-MS/MS were used to analyze the 20 analytes in five edible herbs. The residues of the 20 neonicotinoid insecticides and their metabolites in 109 herbal samples were detected, of which 90 samples were positive, and the residue of total neonicotinoid insecticides ranged from 0.26 to 139.28 μg/kg. Acetamiprid (77.06 %, ≤85.95 μg/kg), imidacloprid (67.89 %, ≤32.49 μg/kg) and their metabolites (-desmethyl-acetamiprid (44.04 %, ≤18.42 μg/kg) and desnitro imidacloprid (48.62 %, ≤16.55 μg/kg) were most frequently detected in herbs. Significant positive correlations were found between imidacloprid/acetamiprid and their metabolites in and . Therefore, more attention may be given to the neonicotinoid insecticide residues in edible herbs in the future.

Cyclaniliprole, a type of the third-generation anthranilic diamide insecticide, was mainly used for management of various pests. Myzus persicae (Hemiptera: Aphididae), known as the peach-potato aphid, is an economically essential pest with worldwide distribution. However, the risk assessment of cyclaniliprole in M.

Honeydew honey is less studied than nectar honey, although it is characterized by peculiar nutritional properties. This is mainly due to its challenging production, which leads to easy counterfeiting and difficult valorization. This contribution aims to provide a comprehensive characterization of the physico-chemical, palynological, functional, and food safety properties of a large sampling of honeydew honeys collected throughout Italy.

Imidacloprid, a widely used neonicotinoid insecticide, targets insect pests but also affects natural enemies. However, the effects of neonicotinoid insecticides on closely related insects remain unclear. We evaluated the harmful effects of imidacloprid on the phytophagous and predaceous .

The current study investigates the systemic effects of imidacloprid, one of the most widely used neonicotinoid insecticides, on the liver and gut microbiome of rats in detail. With consideration of recent discussions on the potential harmfulness of imidacloprid to environmental and human health, the aim was to investigate the influence of this compound in the framework of controlled exposure at different dosages, namely, IMI-5, IMI-10, and IMI-30. Histopathological examination showed that liver morphology changed significantly with the dose, including in terms of cellular disorganization and signs of stress, with an alteration in the hepatic architecture.
