Neonicotinoid insecticides in non-target organisms: Occurrence, exposure, toxicity, and human health risks.

Journal of Environmental Management
Pesticides have consistently portrayed a crucial role in the history of modern agricultural production. Neonicotinoid insecticides are classified as the fourth generation of pesticides, following organophosphorus, pyrethroids, and carbamates.

Urinary neonicotinoid insecticides in children from South China: Concentrations, profiles and influencing factors.

Chemosphere, 2021
Neonicotinoid insecticides can selectively interact with the unique nicotinic acetylcholine receptor subtypes in insects and are considered to be low toxic to mammals.

White-rot fungus Phanerochaete chrysosporium metabolizes chloropyridinyl-type neonicotinoid insecticides by an N-dealkylation reaction catalyzed by two cytochrome P450s.

Journal of Hazardous Materials, 2021
We previously identified a cytochrome P450 (CYP) derived from the white-rot fungus Phanerochaete chrysosporium as involved in degradation of acetamiprid, a neonicotinoid (NEO) insecticide.

NEONICOTINOID INSECTICIDE TOXICOLOGY: Mechanisms of Selective Action

Annual Review of Pharmacology and Toxicology, 2005
▪ Abstract  The neonicotinoids, the newest major class of insecticides, have outstanding potency and systemic action for crop protection against piercing-sucking pests, and they are highly effective for flea control on cats and dogs. Their common names are acetamiprid, clothianidin, dinotefuran, imidacloprid, nitenpyram, thiacloprid, and thiamethoxam.

Measuring urinary concentrations of neonicotinoid insecticides by modified solid-phase extraction-ultrahigh performance liquid chromatography-tandem mass spectrometry: Application to human exposure and risk assessment.

Chemosphere, 2021
Neonicotinoid insecticides are the most widely used insecticides in the world. However, some experiments in vivo and vitro have shown association between neonicotinoids exposure and adverse effects in non-target mammals. The aims of this study were to 1)

Neonicotinoids and Nitrogenous Insecticides

1998
Nicotine has never achieved the prominence that the synthetic insecticides have attained due to its expensiveness, lack of commercially applicable synthesis, extreme toxicity to mammals, and limited insecticidal spectrum. The mode of insecticidal action of nicotine was clarified by Yamamoto (Yamamoto et al.

Ecotoxicity of Neonicotinoid Insecticides to Bees

2010
This chapter reviews the available data on the toxicity of neonicotinoid insecticides to bees that are the prominent and the most economically important group of pollinators worldwide. Classical and new methods developed to take into account the characteristics and different types of effects of the neonicotinoid insecticides to bees are described.

Combination of zeolitic imidazolate framework-67 and magnetic porous porphyrin organic polymer for preconcentration of neonicotinoid insecticides in river water.

Journal of Chromatography A, 2021
A nanostructured material composed of zeolitic imidazolate framework-67 and magnetic porous porphyrin organic polymer (ZIF-67@MPPOP) was successfully synthesized and applied for the enrichment of neonicotinoid insecticides in river water.

Dihydropiperazine Neonicotinoid Compounds. Synthesis and Insecticidal Activity

Journal of Agricultural and Food Chemistry, 2003
Syntheses of various isomeric dihydropiperazines can be approached successfully by taking advantage of the regioselective monothionation of their respective diones. Preparation of the precursor unsymmetrical N-substituted piperazinediones from readily available diamines is key to this selectivity. The dihydropiperazine ring system, as exemplified in 1-[

Photothermal-induced partial Leidenfrost superhydrophobic surface as ultrasensitive surface-enhanced Raman scattering platform for the detection of neonicotinoid insecticides

Sensors and Actuators B: Chemical, 2021
In view of the urgent demand to determine neonicotinoid insecticides in real samples, we first report a photothermal-induced partial Leidenfrost superhydrophobic (PIPLS) sensor using gold colloid and highly roughened SiO2/PDMS surface coupled with few ...
