• Chemical HazardsHelping Keep Communities Safe from Chemical Hazards During Severe Weather

    The destruction wrought by extreme weather is often spectacular in its devastation, but the quiet threat of subsequent chemical release can be just as deadly. Damage to infrastructure can lead to toxic substances like chlorine or ammonia contaminating our air and water.

  • Cyanide detectionKeeping First Responders Safe by Detecting Cyanide Poisoning after Fires

    When first responders rush to a burning building to subdue the fire and save lives, it is not just the flames that are dangerous and potentially lethal, but also toxic fumes like cyanide that are released when certain materials are incinerated. These fumes, mixed with smoke, are so toxic that even in very low quantities may pose more risk than the fire itself. Chemists at DHS S&T have invented a test to indicate possible toxic cyanide exposure at the fire scene.

  • Transporting AmmoniaSecuring Transportation of Ammonia

    Ammonia is used in many cleaning products, and it also fertilizes most of the U.S. agricultural crops. It will soon be used as emission free green fuel to power ships. With all of the many benefits, there are risks as well, as ammonia is the most produced and widely distributed toxic inhalation hazard chemical in the United States. If released in large quantities, it poses a significant risk to life and the health of those exposed.

  • BiosensorsNew Biosensor Detect Toxins and More

    A new device is not quite the Star Trek “tricorder” medical scanner, but it’s a step in the right direction. The Portable EnGineered Analytic Sensor with aUtomated Sampling (PEGASUS) is a miniaturized waveguide-based optical sensor that can detect toxins, bacterial signatures, viral signatures, biothreats, white powders and more, from samples such as blood, water, CSF, food, and animal samples.

    The Organization for the Prohibition of Chemical Weapons (OPCW) on Monday released the findings of the second report by the OPCW Investigation and Identification Team (IIT). IIT concludes that units of the Syrian Arab Air Force used chemical weapons in Saraqib on 4 February 2018.Since 2011, the year the civil war in Syria began, the Assad regime has launched atleast 336 chemical attacks, using Sarin and chlorine, against Sunni civilians.

  • BOOKSHELF : Nerve agentsToxic: A History of Nerve Agents, from Nazi Germany to Putin’s Russia

    By Chris Quillen

    Nerve agents are very much in the news these days. Bashar al-Assad’s government in Syria repeatedly used Sarin against its own people during that country’s civil war. The Putin regime employed Novichoks in both Russia and the United Kingdom against citizens it deemed insufficiently loyal to Moscow. North Korea’s Kim Jong Un utilized VX in the assassination of his brother at an airport in Kuala Lumpur, Malaysia. Across the globe, the use of nerve agents is challenging the international nonproliferation regime in numerous ways.

  • DetectionInnovative Chemical Weapons Detection Technology

    An innovative new chemical detection technology called SEDONA, or SpEctroscopic Detection of Nerve Agents, was recognized as a 2020 R&D 100 Award-winner.When deployed at security checkpoints, border crossings, and ports of entry across the country, SEDONA will enhance DHS’s abilities to detect and intercept dangerous chemicals and nerve agents.

    A newly designed spectroscopy instrument allows scientists, industry, and governments to decipher even trace amounts of chemicals using the Earth’s own magnetic field. The portable tool will help scientists, industry, and governments easily detect and identify trace amounts of chemicals.

  • BOOKSHELF: Syria’s chemical weaponsThe “Red Line” That Wasn’t

    By Chris Quillen

    Syrian President Bashar al-Assad’s use of chemical weapons (CW) against his own people is the greatest challenge the Chemical Weapons Convention has ever faced. This breach of the taboo against CW use sparked numerous national and international investigations to determine the details of exactly what happened and who had done it. Joby Warrick’s Red Line is a useful addition to this debate, but the definitive book on the use of chemical weapons in the Syrian civil war remains to be written.

    Scientists have successfully tested a fully autonomous robot that will help defense and security personnel dealing with hazardous scenes. The development of the robot means that humans and machines can now share the burden of detecting and report dangerous chemicals over large areas.

    Trained dogs are incredible chemical sensors, far better at detecting explosives, narcotics and other substances than even the most advanced technological device. But one challenge is that dogs have to be trained, and training them with real hazardous substances can be inconvenient and dangerous.

    A new report offers the most comprehensive investigative report to date on Syria’s Scientific Studies and Research Centre (SSRC), the entity at the heart of Syria’s chemical weapons program. The report contains new information on how the Syrian government orchestrated attacks using sarin, a banned nerve agent whose use is considered a war crime.

  • Argument: Chemical weaponsHow Putin Borrowed a Page from Assad’s Chemical Weapon Playbook

    Russia use of Novichock to poison opposition leader Alexei Navalny highlights a problem against which Western countries have not yet been able to devise an effective policy: the use of chemical weapons by authoritarian regimes against domestic regime critics. Preventing Russia, or any other autocratic ruler, from using poisons against domestic opponents is a tall order, Gregory D. Koblentz writes, but “Understanding the motivations of authoritarian leaders, and the intensity of their concerns about regime security, however, is the first step towards devising an effective strategy for deterring their use of chemical, and possibly someday biological, weapons against their own people.”
