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 ...

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...

background: organophosphorus (op) poisoning is a major public health problem in developing world. op pesticides inhibit carboxylic esterase enzymes including plasma cholinesterase (pche). clinical manifestations following op poisoning can be associated with the extent of decrease of pche. this study was designed to investigate the relevance of pche level to clinical manifestations in op poisoni...

the aim of this study was to determine the feasibility of coupling an electrochemical process with a biological treatment in order to degrade phosmet, an organophosphorous pesticide. the absence of biodegradability of phosmet by pseudomonas fluorescens and activated sludge was verified in our operational conditions. so, a conventional biological treatment is not appropriate for phosmet polluted...

Aim of the study: To assess the metabolism of liver & lipid peroxidation status in the patients with organophosphorus compounds poisoning. Materials & Methods: 50 patients of both sex, age group 25 -50 years who got admitted for organophosphorous compounds poisoning in Government General Hospital Chennai-3 were chosen for the study. Age and sex matched 50 healthy volunteers were treated as cont...

Background Widespread use of organophosphorous compounds (OPs) in agriculture and as nerve agents as well as a lack of clinically effective antidotes initiated the synthesis of new pyridinium bis-aldoximes (K-compounds) with high potency in reactivating acetylcholinesterase irreversibly inhibited by OPs [1,2]. We aimed to optimize an HPLC method sensitive enough to determine K-compounds from di...
