Organophosphorous compounds have been employed as pesticides and chemical warfare nerve agents. Toxicity of organophosphorous compounds is a result of excessive cholinergic stimulation through inhibition of acetyl cholinesterase. Clinical manifestations include cholinergic syndromes, central nervous system and cardiovascular disorders. Organophosphorous pesticide poisonings are common in develo...

The present investigation deals with histopathological and histochemical studies of profenophos on liver and kidney of male albino rats and the protective effects of vitamin C and ginseng to reduce the deleterious effect induced by profenophos. Oral administration of profenophos at dose level of 1 /10 LD50 for 15 successive days induced histological changes in liver and kidney. No histological ...

This work reports the analytical application of surface-enhanced Raman spectroscopy (SERS) in the trace analysis of organophosphorous pesticides (trichlorfon and glyphosate) and model organophosphorous compounds (dimethyl methylphosphonate and o-ethyl methylphosphonothioate) bearing different functional groups. SERS measurements were carried out using Ag nanocubes with an edge square dimension ...

The aim of this study was to develop a simple and efficient sample preparation methodology in pesticide multiresidue analysis that shortens the analytical process during extraction and cleanup. We have conducted recovery tests of about 300 pesticides in foods with a modified method reported previously. Ten g of sample was extracted with 20 ml of acetonitrile using a high-speed homogenizer. One ...

A total of 144 Kg of strawberry and 38 soil samples, representing two types of farming production e.g. conventional (C), organic (O), was collected from (Bilbeis and AL-Salhia, New AL-Sharqiya governorate) Egypt. Pesticides residues were determined by gas chromatography with mass selective detector (GC-MSD). This method used to determine 86 pesticide residues with a broad range of physico-chemi...
