Latest facts and figures

The 7 States Parties (A State Party, Albania, India, Iraq, the Libyan Arab Jamahiriya, the Russian Federation, and the United States of America) which have declared chemical weapons must destroy 8.67 million items, including munitions and containers containing in total, 71,195 metric tonnes of extremely toxic chemical agents. Albania, India and a third country have completed destruction. By comparison, a tiny drop of a nerve agent, no larger than the head of a pin, can kill an adult human being within minutes after exposure.The OPCW verifies that the destruction process is irreversible. At the same time, States Parties in the process of destroying chemical weapons are obliged to place the highest priority on the safety of people and on protecting the environment.

50,619, or 71.10%, of the world's declared stockpile of 71,195 metric tonnes of chemical agent have been verifiably destroyed. (As at 30/11/2011)
