Imidacloprid is a newer insecticide of the group Neonicotinoids. It safer to humans and hence considered better alternative organophosphorus compounds, especially in areas like Nepal with higher incidence deliberate self-poisoning. There has been an increase number reported cases imidacloprid poisoning from South-East Asian countries, but none Nepal. We report case admitted Intensive Care Unit ...

A tandem ion mobility instrument based on differential mobility spectrometry (DMS) was used to demonstrate selectivity in response through differences in field dependence of mobility for ions in purified air at ambient pressure. The concept of chemical selectivity solely from characteristic dispersion curves or from field dependence of ion mobility was experimentally demonstrated in three steps...

Synthetic organophosphorus compounds (OP) are widely used in agriculture to control agricultural and household pests. The excessive use of OP compounds have generated a number of environmental problems such as contamination of air, water and terrestrial ecosystems, harmful effects on different biota, and disruption of biogeochemical cycling. Therefore, there is a need for economical and dependa...

M. Geoffroy () Department of Physical Chemistry, University of Geneva, 30 quai Ernest Ansermet, 1211 Geneva, Switzerland e-mail: [email protected] Abstract The main radical species produced by radiolysis of organophosphorus compounds are described in this chapter. Their identification is generally based on an analysis of the g and hyperfine tensors obtained from EPR experiments performe...

The thermochemistry and kinetics of organophosphorus compounds were studied, with BAC-MP4 method estimations as a basis and PM3 semi-empirical estimations for many new compounds. New group additivity values were proposed for enthalpies of formation at 298 K, and entropies and heat capacities of species involving pentavalent phosphorus bonded to carbon, hydrogen, oxygen, fluorine, nitrogen, and ...

In an attempt to develop effective antidote against organophosphorus intoxication, some new imidazole-pyridinium mono-oximes, long chain pyridinium mono-oximes and cholineacetyltransferase inhibitors were synthesised. These compounds were evaluated for their in vivo therapeutic protection and neuromuscular function studies in rodents. The results indicate that SPK-series oximes may be useful ag...
