Protection against harmful chemical compounds is a major social concern, especially warfare agents (CWAs) that are easy to synthesize and can cause mass casualties. The metal oxides with large surface area, porous structures, number of active sites have shown outstanding performance for the adsorption decontamination CWAs. However, single-component show lower degradation rate agents. Here, we d...

The Chemical Weapons Convention prohibits the development, production, acquisition, stockpiling, retention, transfer or use of chemical weapons by Member States. Verification of compliance and investigations into allegations of use require accurate detection of chemical warfare agents (CWAs) and their degradation products. Detection of CWAs such as organophosphorus nerve agents in the environme...

objective: mental disorders are more common among the chemically injured veterans rather the than the normal population. the main aim of this study was to evaluate the effects of mustard gas (mg) on mental health and quality-of-life (qol) in the people exposed to it based on reviewing valid published articles. methods: we searched english databases including medline, isi and scopus as well as f...

sulphur mustard (sm) is an alkylating agent that was first used as a chemical warfare agent during the first world war in 1917. sm is readily absorbed from the skin, respiratory and gastrointestinal tract and is distributed to several organs. sm may act rapidly and persistently upon dna replicating mechanism of the individual cells during mitosis particularly in the hematopoietic system. of 233...

A class of heterogeneous catalysts based on commercial bentonite from natural origin, containing at least 80 wt% of montmorillonite clay, was designed to transform selectively and under mild conditions toxic organosulfur and organophosphorus chemical warfare agents into non-noxious products with a reduced impact on health and environment. The bentonite from the natural origin was modified by in...

tio2 nanoparticles, as a photocatalyst for oxidation of dimethyl methylphosphonate (dmmp) as an organophosphorus simulant of chemical warfare agent, were prepared by using sol-gel method. the prepared nanoparticles were then modified with transition metals in order to decrease the electron-hole recombination and increase the photocatalytic activity. transition metal ions including pt, pd and ni...

The use of negative ion monitoring mode with an atmospheric pressure ion mobility orthogonal reflector time-of-flight mass spectrometer [IM(tof)MS] to detect chemical warfare agent (CWA) degradation products from aqueous phase samples has been determined. Aqueous phase sampling used a traditional electrospray ionization (ESI) source for sample introduction and ionization. Certified reference ma...
