Chemical Treatment and Decomposition Technique of the Chemical Warfare Agents Containing Arsenicals

[Chemical treatment and decomposition technique of the chemical warfare agents containing arsenicals].

The old Japanese army developed several chemical warfare agents on Ohkuno Island in Seto inland sea, Hiroshima Japan, during the period between 1919 and 1944. These chemical agents including yperite (mustard; irritating agent), lewisite (irritating agent), diphenylchloroarsine (DA; vomiting agent), diphenylcyanoarsine (DC; vomiting agent) and other poisonous gases were manufactured to be used i...

Chemical warfare agents: toxicology and treatment

The large-scale use of chemical warfare agents first occurred during World War I (the "chemists' war"), and was thereafter repeated at irregular intervals, most recently during the Iran-Iraq conflict of the 1980s. There was consequently a possibility that chemical weapons might be used in the Gulf war. The threat posed by terrorist groups became evident in 1994-95, when Japanese civilians were ...

FETAL DEATHS AND PARENTAL EXPOSURE TO CHEMICAL WARFARE AGENTS

In the present work we studied the incidence of fetal deaths among conceptions whose fathers or both parents were survivors of chemical warfare attacks by Iraq. We showed that there was significant correlation between frequency of fetal deaths among conceptions which eventuated after exposure of the parents to gas bombs compared to the frequency of fetal deaths among the control group. Thi...

History of chemical and biological warfare agents.

Chemical and biological warfare agents constitute a low-probability, but high-impact risk both to the military and to the civilian population. The use of hazardous materials of chemical or biological origin as weapons and for homicide has been documented since ancient times. The first use of chemicals in terms of weapons of mass destruction goes back to World War I, when on April 22, 1915 large...
