Currently available treatments mitigate the effect of the nerve agents, and could be vastly improved by means of scavengers of the nerve agents. Consequently, efforts have been made over the years into investigating enzymes, also known as bioscavengers, which have the potential either to trap or hydrolyze these toxic compounds. We investigated the previously described esterase 2 from Thermogutta terrifontis (TtEst2) as a potential bioscavenger of nerve agents. As such, we assessed its potential against G-agents (tabun, sarin, and cyclosarin), VX, as well as the pesticide paraoxon. We report that TtEst2 is a good bioscavenger of paraoxon and G-agents, but is rather slow at scav- enging VX. X-ray crystallography studies showed that TtEst2 forms an irreversible complex with the aforementioned agents, and allowed the identification of amino-acids, whose mutagenesis could lead to better scavenging properties for VX. In conjunction with its cheap production and purification Citation: Bzdrenga, J.; Trenet, E.; processes, as well as a robust structural backbone, further engineering of TtEst2 could lead to a Chantegreil, F.; Bernal, K.; Nachon, F.; stopgap bioscavenger useful for in corpo scavenging or skin decontamination.

  • Soman Is a Human-Made Chemical Warfare Agent Classified As a Nerve Agent
    District Health Department #2 Soman Fact Sheet RCP-AP-06l SOMAN WHAT YOU SHOULD KNOW What is Soman? Soman is a human-made chemical warfare agent classified as a nerve agent. Nerve agents are the most toxic and rapidly acting of known chemical warfare agents. Soman is a tasteless, odorless, clear liquid with a slight camphor odor (similar to vapor rub). How Can People Be Exposed to Soman? Following a release of Soman into the air, people can be exposed through skin contact, eye contact, or inhalation. Soman also mixes easily with water so it is possible that it could be used as a poison through the water. What Are The Symptoms of Soman? Individuals who are exposed to a low or moderate dose of soman by inhalation, ingestion, or skin absorption may experience some or all of the following symptoms within seconds to a few hours after exposure: runny nose, watery eyes, small pupils, eye pain, blurred vision, drooling and excessive sweating, cough, chest tightness, rapid breathing, diarrhea, increased urination, confusion, drowsiness, weakness, headache, nausea/vomiting, slow or fast heart rate, and abnormally high or low blood pressure. A large dose of Soman may lead to loss of consciousness, convulsions, paralysis, and respiratory failure leading to death. What are the Long-term Effects of Soman Exposure? Mild or moderately exposed people usually recover completely. Severely exposed people are not likely to survive. Can Soman Be Treated? Treatment consists of removing Soman as soon as possible and providing supportive medical care in a hospital setting. Antidotes are available for Soman.

Both countries agreed that the study would be completed by early 2010, with recommendations for their political authorities. The bilateral relationship has developed considerably in recent years, such as the establishment of a Joint Commission reflecting the shared commitment of the two countries to advance cooperation on a wide range of bilateral and regional interests. Indonesia and Chile have worked closely and they are willing to expand further its relationship given the importance of the two nations in the Southeast Asia and Latin America region. Indonesia the largest economy in ASEAN and the world’s fourth most populous nation, and Chile one of the most developed economies in the Latin America region. Despite of trade potentials, trading relationship between two countries is still very limited.

  • NIOSH-DOD-OSHA SPONSORED Chemical and Biological Respiratory Protection Workshop Report
    NIOSH-DOD-OSHA SPONSORED Chemical and Biological Respiratory Protection Workshop Report John M. Dower, Richard W. Metzler, Frank M. Palya, Jeff A. Peterson, Molly Pickett-Harner U.S . DEPARTMENT OF HEALTH AND HUMAN SERVICES Public Health Service Centers for Disease Control and Prevention National Institute for Occupational Safety and Health February 2000 FOREWORD In May 1998, President Clinton issued Presidential Decision Directive 62 (PDD-62), “Combating Terrorism” and made the fight against terrorism a national domestic security issue. This Directive creates a new and more systematic approach to achieve the President's goal of ensuring that we meet the threat of terrorism in the 21st century with the same rigor that we have met military threats in this century. PDD-62 establishes the Office of the National Coordinator for Security, Infrastructure Protection, and Counter-Terrorism. The National Coordinator will oversee the broad variety of relevant policies and programs including such areas as counter-terrorism, protection of critical infrastructure, preparedness, and consequence management for weapons of mass destruction. NIOSH, DOD, and OSHA organized this workshop to bring together partners to coordinate activities in support of this Directive. Over the fifteen months since publication of PDD-62, municipal, state, and national guard responder groups, particularly those in locations considered potential targets, have been hastily developing response and consequence management plans. These plans—which include establishing procedural and equipment infrastructures and training emergency response personnel for chemical and biological terrorism—have raised numerous issues about potential attack scenarios and agents, such as how best to address hazard detection, personal protective equipment, responder needs, and public health and medical concerns.

    THE FOUR LIKELY BINARY AGENTS Working paper Charles P. Blair Last Updated, January 2013 Binary sarin (GB2) – developed by the U.S. Binary soman (GD2) VX binary (VX2) – developed by the U.S Novichok agent (“New Comer) –developed by the Soviets Additionally, Eric Croddy has written that VNSAs may use “binarytype designs” in an attack…with simple designs most likely using common chemical ingredients (e . g. , c ya n id e . ) ” 1 Aum is an example o f t h is . 1. Binary sarin . With binary sarin (also referred to as “GB binary” and “GB2”) a forward container has methylphosphonic difluoride (DF), while a second, rear container has an isopropyl alcohol and isopropylamine solution (OPA). The DF resides in the munition prior to use. The OPA is added just prior to launch. After deployment of the weapon, the two canisters rupture, “the isopropyl amine binds to the hydrogen fluoride generated during the chemical reaction, and the chemical mixture produces GB.”2 Experts note that, “The final product of the weapon is of the same chemical structure as the original nerve agent. The term binary refers only to the storage and deployment method used, not to the chemical structure of the substance.”3 With regard to how long it takes the DF and OPA to mix before binary sarin is extant, Eric Croddy notes that, “as in any chemical reaction, a certain amount of time is required for the [binary] reaction to run its course. In the case of GB binary, this required about seven seconds.”4 2. Binary soman (also referred to as “GD binary” and “GD2”).
