Preparation of magnetic flower-like molybdenum disulfide hybrid materials for the extraction of organophosphorus pesticides from environmental water samples.

Journal of Chromatography A, 2020
In this study, the magnetic flower-like molybdenum disulfide hybrid materials (Fe3O4/MoS2) were successfully synthesized by in-situ fabrication method and utilized in the magnetic solid-phase extraction of organophosphorus pesticides. Fe3O4 nanoparticles

Temporal trends in organophosphorus pesticides use and concentrations in river water in Japan, and risk assessment.

Journal of Environmental Science, 2019
We reviewed organophosphorus pesticide use in Japan between 1982 and 2016 using data from the National Institute of Environmental Studies. Organophosphorus pesticide concentrations in river water throughout Japan were taken from the literature, and risk ...

Determination of organophosphorus pesticides in water

1969
Increasing use of organic chemicals for agricultural purposes has caused great concern in recent years. Rachel Carson (1962) was one of the first to focus public attention on the possible hazards connected with pesticide use. Because of this concern, much work (Dugan et al.

A signal-on detection of organophosphorus pesticides by fluorescent probe based on aggregation-induced emission

Sensors and Actuators B: Chemical, 2019
Organophosphorus pesticides (OPs) have been broadly used in agriculture because of their high insecticidal efficiency. However, most OPs are highly toxic, since they can irreversibly inhibit acetylcholinesterase (AChE), leading to the neurotransmitter ...

A Water-stable Luminescent Metal-organic Framework for Rapid and Visible Sensing of Organophosphorus Pesticides.

ACS Applied Materials and Interfaces, 2019
Metal-organic frameworks (MOFs) have shown considerable prospects for sensing pesticide residues. However, the low stability of MOFs in water hinders them from testing food and environmental samples. Herein, we report an easy and cost-efficient synthesis

Fabrication of a novel azamacrocycle-based adsorbent for solid-phase extraction of organophosphorus pesticides in tea drinks

, 2020
A novel azamacrocycle-based adsorbent for solid-phase extraction was synthesized by coupling a 26-membered aromatic-aliphatic-mixed azamacrocycle to 3-chloropropyltrimethoxylsilane-modified silica.

Double quantum dots-nanoporphyrin fluorescence-visualized paper-based sensors for detecting organophosphorus pesticides.

Talanta: The International Journal of Pure and Applied Analytical Chemistry, 2019
A high-sensitivity fluorescence visualization paper-based sensor is developed and used to achieve specific detection and analysis of three organophosphorus pesticides (OPPs: dimethoate, dichlorvos, and demeton) in a "Turn-off-on" detection mode.

Cyanobacterial Degradation of Organophosphorus Pesticides

2020
Pesticides are chemicals which are widely used for the protection of crops from the attack of pathogens. Pesticides include fungicides, insecticides, herbicides, and bactericides. Among the different classes of pesticides used, organophosphorus class of pesticides is commonly used for agricultural applications.

Neurotoxic effects of organophosphorus pesticides and possible association with neurodegenerative diseases in man: A review.

Toxicology, 2018
In this article the neurotoxic disorders appearing in patients exposed to organophosphorus pesticides and known mechanisms involved are reviewed. Organophosphorus compounds cause four main neurotoxic effects in humans: the cholinergic syndrome, the ...
