A German fishing vessel that sank during World War II has been leaking pollutants that are changing the surrounding marine environment in the North Sea, according to a new study.
The torn deck plating of the World War II shipwreck V-1302 John Mahn in the Belgian part of the North Sea.
Even after eight decades, those chemicals and microbes are affecting the"surrounding sediment chemistry and microbial ecology," the researchers wrote in the study. The results hint at the long-term environmental impacts of"The general public is often quite interested in shipwrecks because of their historical value, but the potential environmental impact of these wrecks is often overlooked," Josefien Van Landuyt, one of the study's co-authors and a Ph.D.
The pollutants found in samples from the ocean floor included various heavy metals, including nickel and copper. The highest concentrations of hazardous compounds were found closest to the sunken vessel. "Although we don't see these old shipwrecks, and many of us don't know where they are, they can still be polluting our marine ecosystem," Van Landuyt said in the statement."In fact, their advancing age might increase the environmental risk due to corrosion, which is opening up previously enclosed spaces. As such, their environmental impact is still evolving."
