Development of an enzyme linked immunosorbent assay and an immunochromatographic assay for detection of organophosphorus pesticides in different agricultural products. [PDF]

PLoS ONE, 2012
OBJECTIVE: Organophosphorus (OP) pesticides are considered hazardous substances because of their high toxicity to nontarget species and their persistence in the environment and agricultural products.

Management of acute organophosphorus pesticide poisoning [PDF]

BMJ, 2007
Organophosphorus pesticides are used widely for agriculture, vector control, and domestic purposes. Despite the apparent benefits of these uses acute organophosphorus pesticide poisoning is an increasing worldwide problem, particularly in rural areas.

Mass Spectrometry in Authentication and Forensic Approaches for Determining the Origin of Hazardous Chemicals

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Identification of a chemical agent yields insights into its physicochemical properties. By examining the intrinsic characteristics and environment of a compound, information about its history can be gathered. The main objective of authentication/forensic approaches to chemicals is to trace the history of the compound's origin, regardless of ...

Electrochemical aptasensors for ultrasensitive multiplexed detection: Towards a new era of precision diagnostics and environmental monitoring

VIEW, EarlyView.
Electrochemical aptasensors are emerging as powerful platforms for precision diagnostics and environmental monitoring, owing to their high selectivity, programmability and compatibility with miniaturised systems. However, their broader application is constrained by limited signal intensity and challenges in reliable multiplexed detection.

Probabilistic risk assessment of the environmental impacts of pesticides in the Crocodile (west) Marico catchment, North-West Province [PDF]

, 2008
External agricultural inputs, such as pesticides, may pose risks to aquatic ecosystems and affect aquatic populations, communities and ecosystems. To predict these risks, a tiered approach was followed, incorporating both the PRIMET and PERPEST models ...

The Generics Revolution and the New Economic Geography of the Global Pesticide Industry

Journal of Agrarian Change, EarlyView.
ABSTRACT The global pesticide industry transformed from one dominated by patented products and legacy multinationals with strong manufacturing bases in the United States and EU to one dominated by generic products produced in India and China. We use proprietary market research data, data from regulatory filings, industry press and bilateral trade data ...

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 ...

Alkalinisation for organophosphorus pesticide poisoning

Cochrane Database of Systematic Reviews, 2004
Poisoning with organophosphorus pesticides (OPs) is an important cause of morbidity and mortality in all parts of the world, particularly developing countries. The case-fatality ratio for pesticide intentional self-poisoning is around 10-20% even when the standard antidotes (atropine, oximes and benzodiazepines) are used.

Confirmation of Pesticide Residue Identity. VIII. Organophosphorus Pesticides

Journal of AOAC INTERNATIONAL, 1974
Abstract A chemical confirmation for 5 organophosphorus pesticides is described. After extraction and quantitation by flame photometric detector gas-liquid chromatography (CLC), the organophosphorus pesticides are hydrolyzed in a 10% methanolic-potassium hydroxide solution, followed by derivatization with pentafluorobenzyl bromide to ...

Recent Applications of Propylene Carbonate as a Solvent in Sustainable Organic Synthesis

ChemSusChem, Volume 19, Issue 17, 14 September 2026.
This review evaluates propylene carbonate (PC) as a non‐toxic green solvent in organic synthesis, highlighting its performance in key reactions including cross‐couplings, asymmetric hydrogenations, peptide synthesis and biocatalysis. Across these processes, PC delivers yields comparable to conventional and alternative green solvents.
