In 1997, the Chemical Weapons Convention—a first-of-its-kind global disarmament agreement—came into force. The treaty was championed by the Organisation for the Prohibition of Chemical Weapons (OPCW) with the aim of ridding the world of that class of weapons of mass destruction. In a few weeks time, all 193 countries that are OPCW members will have completely destroyed their declared chemical weapons stockpiles, the organisation says. I visited the OPCW's new ChemTech centre in the Netherlands to find out more. The whole article was published by C&EN Magazine.
