Impact of unexploded ordnance in the Baltic Sea: Study detects toxic munitions chemicals in water samples

It is estimated that about 300,000 metric tons of unexploded ordnance (UXO) remain in the German Baltic Sea. Most of this originates from deliberate dumping after the end of the Second World War. These dumping sites are well documented, with much of the ordnance lying visibly on the seabed, allowing it to be mapped and documented using underwater robots.
