Disposal of chemical weapons in the Baltic Sea

Large quantities of chemical warfare agents were dumped in the Baltic Sea after World War II (WWII). This included 32 000 t of chemical munitions containing approximately 11 000 t of chemical warfare agents which were dumped into the Bornholm Basin and 2000 t of chemical munitions containing approximately 1000 t in the Gotland Basin. Because this material was contained in wooden crates, it was distributed throughout the Baltic. The long-term environmental impact of these agents is unknown.
