Aquatic-terrestrial transfer of neonicotinoid insecticides in riparian food webs.

Journal of Hazardous Materials, 2023
Current-use pesticides are ubiquitous in freshwaters globally, often at very low concentrations. Emerging aquatic insects can accumulate pesticides during their aquatic development, which can be retained through their metamorphosis into terrestrial ...

Exposure to neonicotinoid insecticides and their characteristic metabolites: Association with human liver cancer.

Environmental Research, 2022
Neonicotinoid insecticides (NEOs) are commonly applied for pest control in China and around the world. Previous studies reported that NEOs are hepatotoxic to mammals. However, limited studies have explored the associations between NEOs exposure and liver

Deriving freshwater guideline values for neonicotinoid insecticides: Implications for water quality guidelines and ecological risk assessment.

Science of the Total Environment, 2022
The increased use of neonicotinoid insecticides in aquatic environments poses a significant threat to non-target freshwater species. However, the existing water quality guidelines (WQGs) for neonicotinoids mainly focus on imidacloprid, and only a few ...

Pharmacophore model for neonicotinoid insecticides

Chinese Chemical Letters, 2008
Abstract An effective prediction pharmacophore model (RMS = 0.634, Correl = 0.893, Weight = 1.463, Config = 11.940) was successfully obtained by 3D-QSAR based on a series of nAChR (nicotinic acetylcholine receptors) agonists, which consists of a hydrogen-bonding acceptor, a hydrogen-bond donor, a hydrophobic aliphatic and a hydrophobic aromatic ...
