Baltic Sea bed littered with chemical munitions, report reveals

There are approximately 300,000 tons of chemical weapons, dangerous relics from WWII, currently resting on the bottom of the Baltic Sea, recent reports have revealed.

Cartridges containing chemical explosives, such as mustard gas, lucite, adamsite, phosgene and diphosgene, are reported to be located on the seabed, according to

Almost 400 cases have been recorded where Danish fisherman raised barrels and tanks containing mustard gas or shells loaded with hazardous materials in their nets, reports.

In addition to the fear of interactions with fisherman, there are concerns that the metal cartridges containing the hazardous chemicals will inevitably be affected by corrosion and pose an ecological threat.

“It has been reported that chemical weapons in Lithuania are buried from 84 to 126 meters deep,” Vladas Zulkus, ex-director of the Institute of the Baltic Sea Region History and Archaeology, said, according to

So far, only Denmark is deliberating a possible chemical weapons cleaning program, reports. Cleaning up just one bay of the chemical weapons, however, would require three to five years and cost about $3 billion dollars, a staggering obstacle that has delayed the launch of the initiative.  

Another obstacle faced by the Baltic countries is that the information about the disposal of chemical weapons have been classified for a long time, with England and the United States granted confidentiality until 2017, reports.
