Abstract
The global insecticide market is undergoing significant changes, witnessing a surge in neonicotinoids (NEOs) usage, alongside the persistent application of traditional insecticides, such as organophosphates (OPs), carbamates (CMs) and pyrethroids (PYRs). In this study, therefore, NEOs, OPs, PYRs and CMs were measured in various pomelo tissues and paired soil and leaf samples collected from two pomelo orchards in South China. NEOs exhibited a higher median sum residue in pulp (ΣNEOs: 1.90 ng/g) than traditional insecticides (ΣOPs: 1.69 ng/g, ΣCMs: 0.49 ng/g, and ΣPYRs: 0.33 ng/g). Principal component analysis indicated that NEO residues in pulp was primarily originated from deep soil. Moreover, the migration pathway of NEOs potentially extends from the deep soil to the plant's root system, then travels through the carpopodium to access the pulp, whereas traditional insecticides adhere to a migration pathway that progresses from the epicarp to the pulp. Tissue-specific distribution analysis revealed that NEOs exhibit an enhanced propensity for accumulation in the pulp. In contrast, traditional insecticides display a preference for accumulating in seeds and endocarp. This study first to delineate distinction in residue, migration, tissue-specific distribution between NEOs and traditional insecticides, heightened emphasis is warranted on NEOs and their metabolites within the ambit of the “One-Health” framework.
期刊介绍:
Emerging Contaminants is an outlet for world-leading research addressing problems associated with environmental contamination caused by emerging contaminants and their solutions. Emerging contaminants are defined as chemicals that are not currently (or have been only recently) regulated and about which there exist concerns regarding their impact on human or ecological health. Examples of emerging contaminants include disinfection by-products, pharmaceutical and personal care products, persistent organic chemicals, and mercury etc. as well as their degradation products. We encourage papers addressing science that facilitates greater understanding of the nature, extent, and impacts of the presence of emerging contaminants in the environment; technology that exploits original principles to reduce and control their environmental presence; as well as the development, implementation and efficacy of national and international policies to protect human health and the environment from emerging contaminants.
