In 1946, the Polish cargo ship SS Kielce, loaded with munitions, sank about four miles off the coast of England. Its attempted salvage in 1967 resulted in an explosion equivalent to an earthquake measuring 4.5 on the Richter scale.
Nobody was injured that time, but others haven’t been so lucky. Over 110 people have died from unexploded ordinance (UXO) dumped in the North Sea since 1945.
A study reported in Marine Technology News this week investigated another risk such munitions pose. The south-western Baltic Sea has about 3,000 kilograms of dissolved toxic chemicals released from unexploded ordnance, according to the study by the GEOMAR Helmholtz Centre for Ocean Research Kiel. Unexploded ordnance contains toxic substances such as TNT (2,4,6-trinitrotoluene), RDX (1,3,5-trinitro-1,3,5-triazine), and DNB (1,3-dinitrobenzene), which are released into the seawater when the metal casings corrode.
The contamination is expected to increase over time as metal casings continue to corrode, releasing more and more toxic compounds - a process projected to continue for at least 800 years.
Two EU-funded projects began last year to help mitigate the threat of the estimated 1.6 million tonnes of dumped munitions in European seas. The project teams aim to advance
