91% of declared chemical weapons destroyed*

The Organization for the Prohibition of Chemical Weapons (OPCW) has destroyed about 91% of declared chemical weapons stockpiles. But questions persist over how much clandestine stock of this weapon of mass destruction (WMD) remains in the hands of rogue states and non-state groups. Other WMDs (nuclear and biological) also continue to pose threats to global security. Livermore, an OPCW-certified laboratory, applies its chemical, nuclear, and biological forensics expertise to help investigate, identify, and counter all WMD threats.
