This article reviews a detailed and timely evolution of Nuclear Biological Chemical (NBC) protective clothing. The increased threat NBC weapons underlines the need for clothing first responders, service personnel as well civilians. material selection criteria have been changed considerably with development advance technical fibers to sustain CWA fulfill precisely suits. Because advancement, in ...

We investigated the association of 15 exposures, 10 stressors, and 18 life events with illness symptoms reported by 978 veterans who believe they suffer from Gulf War-related illnesses. A mail survey was completed by veterans (60% response rate) from the Gulf War Health Registry. Variables most associated with high symptom group membership were reported chemical/biologic warfare (CBW), concerns...

Introduction Remediation of environment polluted with toxic chemical warfare agents (CWA) is a challenging task for authorities who deal with public health and environmental safety. Abnormal health symptoms appear when the human beings are exposed to these hazardous chemicals. Decontamination of surface or environment tainted with these toxic chemicals is the main job we have to do, to avoid he...

An overview is given of biological markers of exposure to chemical warfare agents. Metabolites, protein, and/or DNA adducts have been identified for most nerve agents and vesicants and validated in experimental animals or in a small number of human exposures. For several agents, metabolites derived from hydrolysis are unsatisfactory biomarkers of exposure because of background levels in the hum...

On-site monitoring and detection are necessary in the crisis and consequence management of wars and terrorism involving chemical warfare agents (CWAs) such as sarin. The analytical performance required for on-site detection is mainly determined by the fatal vapor concentration and volatility of the CWAs involved. The analytical performance for presently available on-site technologies and commer...

Solid-phase microextraction (SPME) is directly integrated with low temperature plasma ionisation mass spectrometry to rapidly detect organophosphate chemical warfare agent simulants and their hydrolysis products in chemical mixtures, including urine. In this sampling and ionization method, the fibre serves: (i) to extract molecules from their native environment, and (ii) as the ionization elect...

Sarin is a very toxic organophosphorus chemical warfare agent which has been used in different wars. According to an immediate demand of detection, secure approachs to break down this toxic nerve agent, the study on decomposition of sarin achieve significance. In this work, we have made endeavors of discovering an approach to neutralize this hazardous kind by adsorption of this molecule by C20 ...

sulfur mustard (sm) is a chemical warfare agent which was widely used in the world war i and more recently during gulf war in the early 1980s'. sm is a strong alkylating agent with known mutagenic and carcinogenic effects but only few studies have been published on its teratogenicity. since sm has been widely used as a chemical weapon by the iraqi regime against the iranian soldiers as well as ...

Realistic testing of chemical and biological defense systems requires an actual warfare agent. But use of such an agent is restricted to laboratory containment chambers, which are not realistic. This state of affairs has driven the chemical and biological defense community to integrate developmental testing and operational testing. Systems are challenged with both agent and simulant in laborato...
