Organophosphorous (OP) chemical warfare nerve agents mainly sarin and tabun were used during the Iran-Iraq war with high mortalities. In addition to atropine and oximes, the followings have recently been used successfully for the treatment of OP poisoning. 1. Sodium Bicarbonate: Infusion of high doses of sodium bicarbonate (5 mEq/kg in 60 min. followed by 5-6 mEq/kg/day to obtain arterial blood...

In this paper the efficiency of a method for the separation and identification of pesticides in lanolin is presented. Theses pesticides belong to the organophosphorous and synthetic pyrethroids families. After the gel permeation chromatography, pesticides are separated from lanolin into two fractions corresponding to the two families, which simplify subsequent analysis by gas chromatography.

This contribution highlights correlation between the surface concentration of a chemisorbed organophosphorous probe (flavin mononucleotide) and the relative hydroxyl surface coverage of nanostructured ITO electrodes, which can be tuned during post-deposition reductive annealing. The resulting modified electrodes are very stable in aqueous solution, highly hydrophilic and fully-accessible to the...

A simple, efficient, facile and surface mediated method for synthesis of hydrazides of organophosphorous acids has been developed from their corresponding chloridates using calcium oxides as a solid support at room temperature. The developed method gave the desired hydrazides in excellent yields (7592%) and avoids the use of column chromatography.

kumasi, sekondi-takoradi, and accra are the major recipients of agricultural commodities or productions in ghana, primarily due to their population and ready markets. to ensure food security, meet food demands, and mitigate the threats posed by pests and diseases, pesticides are used when cultivating vegetables and fruits in ghana. the present study has been conducted to assess the concentratio...

A multi-residue method for determination of fi ve groups of 85 pesticides organochlorine, carbamate, organophosphorous, pyrethroid and others in non-fatty food, e.g. vegetables, fruits and green tea is described. The method is based on stir bar sorptive extraction (SBSE) coupled to thermal desorption (TD) and retention time locked (RTL) GC-MS

A new microengine-based built-in-platform exploiting a surprising dual action with solution mixing and control of the reaction parameters, has been applied for accelerating chemical reactions (organophosphorous nerve agents hydrolysis) and electrochemical detection of non-hazardous by-product (p-nitrophenol) using printable sensor strip.
