BACKGROUND Poisoning with organophosphorus (OP) insecticides is a major global public health problem, causing an estimated 200,000 deaths each year. Although the World Health Organization recommends use of pralidoxime, this antidote's effectiveness remains unclear. We aimed to determine whether the addition of pralidoxime chloride to atropine and supportive care offers benefit. METHODS AND FI...

Pesticide poisoning is a significant burden on health care systems in many low-income countries. This study evaluates cases of registered pesticide poisonings treated in selected rural (N = 101) and urban (N = 212) health facilities in Uganda from January 2010 to August 2016. In the urban setting, pesticides were the most prevalent single poison responsible for intoxications (N = 212 [28.8%]). ...

Consumption of pesticide contaminated vegetables pose a major threat to public health. High Performance Liquid Chromatography (HPLC) with a Photo Diode Array detector (PDA) was used to determine two organochlorines (methoxychlor and DDT), seven organophosphorus (acephate, chlorpyrifos, fenthion, fenitrothion, malathion, parathion, and ethion), two carbamate (carbaryl and carbofuran) and one pyr...

Pesticides are widely used in agriculture, and pesticide residues have become a public concern. So far, no analytical method has been available for the rapid and quantitative analysis of most food pesticides. In this study, the application of micro-surface-enhanced Raman spectroscopy (SERS) for analysis of the typical organophosphorus pesticide dimethoate is demonstrated. Huge enhanced Raman si...

The study aimed to assess the association of long-term pesticide exposure (≥5 years) with hematological, serum biochemical parameters and acetylcholinesterase activity in farm workers. These pesticides included organophosphorus pesticides, carbamates, pyrethroids, dithiocarbamates, and other pesticides such as endosulfan. Applying a cross-sectional study design, 69 females from a pesticide-expo...

Rainfall samples were collected during the 2003 and 2004 growing seasons at four agricultural locales across the USA in Maryland, Indiana, Nebraska, and California. The samples were analyzed for 21 insecticides, 18 herbicides, three fungicides, and 40 pesticide degradates. Data from all sites combined show that 7 of the 10 most frequently detected pesticides were herbicides, with atrazine (70%)...

Introduction: Chlorpyrifos is an organophosphorus pesticide that is commonly used in agriculture. This toxin is harmful to a wide range of organisms, including living organisms, useful arthropods, fish, birds, humans, animals, and plants. There are many physical, chemical, and biological methods for the removal of organophosphorus pesticides from ecosystems, among which biodegradation is prefer...

Abstract In this study, a new microextraction method based on hydrophobic deep eutectic solvents was developed for the extraction and preconcentration of organophosphorus pesticides from beverage samples. The were synthesized choline chloride 4-chlorophenol. Main experimental parameters investigated to improve efficiency. proposed achieved satisfactory linear range between 50 2,000 μg L −1 with...

A sensitive and flexible detection method for organophosphorus pesticides (OPs) is a crucial request to avoid their further expanded pollution. Herein, an acetylcholinesterase (AChE) electrochemical sensor, based on the co-modification of ZIF-8 graphene (GR), was constructed OPs. ZIF-8/GR composite can provide stable biocompatible environment loading AChE accelerate chemical reaction electrode ...

Aiming to introduce a multiresidue analysis for the trace detection of pesticide residues belonging to organophosphorus and triazine classes from olive oil samples, a new sample preparation methodology comprising the use of a dual layer of "tailor-made" molecularly imprinted polymers (MIPs) SPE for the simultaneous extraction of both pesticides in a single procedure has been attempted. This wor...
