Schiff Base‐UiO66 Composite‐based Dispersive Micro Solid‐Phase Extraction of Pesticides From Fruit Juices Combined With Dispersive Liquid‐Liquid Microextraction Prior to Gas Chromatography‐Flame Ionisation Detection

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT A dispersive micro solid‐phase extraction method was introduced using a Schiff base‐UiO66 nanocomposite as the adsorbent in the extraction of multi‐class pesticide residues in pear, cherry, grape, and apricot juices. The extraction procedure was hyphenated with a liquid‐phase microextraction procedure, providing a high preconcentration factor ...

Evaluation of intravenous lipid emulsion as a novel therapeutic antidote in severe organophosphorous poisoning- A prospective randomized, comparative study [PDF]

Al Ameen Journal of Medical Sciences, 2019
Background: Organophosphorus compounds are usually esters, amides or thiol derivatives of phosphonic acid and form a large family (>50000 compounds). The principal use of these compounds are as pesticides in agriculture, mainly as insecticides.

Nitrobenzene poisoning presenting as Methemoglobinemia

Muller Journal of Medical Sciences and Research, 2014
Consumption of toxic compounds in an attempt to commit suicide is very common. Organophosphorus compounds are the most commonly consumed and fatal poisons. Nitrobenzene consumption for suicidal purposes is very rare.

Integrated Multispectroscopic Identification of Organophosphorus and Triazine Pesticide Mixtures via DFT–Spectroscopy‐Integrated Identification Method (D‐SIIM)

Analysis &Sensing, Volume 6, Issue 6, November 2026.
Identifying unknown chemicals in mixtures is limited by the reference libraries available. D‐SIIM instead cross‐validates experimental IR, Raman, and NMR spectra against DFT predictions, resolving all components of pesticide mixtures containing up to four multiring organophosphorus and triazine compounds including one for which GC–MS screening proved ...

Enhanced Resolution in EPR Spectroscopy: Solid para‐Hydrogen Resolves Proton Hyperfine Splitting in the Diphenylphosphinyl Radical

ChemistryEurope, Volume 4, Issue 11, November 2026.
The diphenylphosphinyl radical 1 was investigated under matrix isolation conditions using IR, UV/Vis, and EPR spectroscopy. Solid para‐hydrogen was found to represent a powerful medium to resolve the hyperfine structure of a phosphorus‐centered π radical 1 by EPR spectroscopy.

Neurotoxicity of Organophosphorus and Dithiocarbamate Compounds.

Nippon Eiseigaku Zasshi (Japanese Journal of Hygiene), 2003
The neurotoxicity of organophosphorus compounds (OPs) including leptophos, TOCP and triphenyl phosphite and dithiocarbamate compounds were reviewed in this study. The major neurotoxicities of OPs were acute toxicity produced by the acetylcholine esterase (AChE) inhibiting action of OPs and delayed neurotoxicity produced by such OPs as leptophos and ...
