A DEADLY LEGACY

"The last thing you might expect to encounter exploring the ocean floor is a chemical weapon. But it seems hundreds of thousands of tonnes of them have been dumped into the sea, and no one knows exactly where the weapons are. Now, scientists are calling for weapons sites to be mapped for safety's sake. Between 1946 and 1972, the US and other countries pitched 300,000 tonnes of chemical weapons over the side of ships or scuttled them along with useless vessels according to public reports by the Medea Committee, a group of scientists given access to intelligence data so they can advise the US government on environmental issues. But the military have lost track of most of the weapons because of haphazard record keeping combined with imprecise navigation. Even the exact chemicals were not always noted, though there are records of shells, rockets and barrels containing sulphur mustard and nerve gas."
