Corrosion of sunken WWII-era munitions in the North and Baltic Seas

Summary

German researchers warn that chemicals from an estimated 1.6 million tonnes of conventional munitions dumped in the North and Baltic Seas after 1945 are leaching into the marine ecosystem as the metal casings corrode, having been found in fish, mussels and stranded whales, with liver tumours noted in some fish. Germany has begun pilot projects to systematically remove the munitions using floating platforms, though researchers estimate the task will take decades given the scale of contamination.
