Unexpected Nazi-era legacy: Fish tumors

German researchers have uncovered a 25 percent incidence of tumors among a type of flatfish inhabiting one area of the Baltic Sea, close to the northern German city of Kiel. They believe the cancerous growths found on the species known as the common dab could be linked to the estimated 1.6 million of tons of armaments that were dumped at the bottom of the Baltic and North Seas at the end of World War II. The high prevalence compares to a 5 percent tumor rate in three other areas of the Baltic, researchers said. Presenting their evidence to a conference in Rostock on Monday, scientists from the Thünen Institute of Fishing Ecology said the rate of tumors among dab fish in shallow coastal waters was much higher than previously thought. Empasizing that their findings are preliminary, researchers warned that as the munitions continue to rust and leak discharge, the environmental impact of the mass dumping of Nazi-era weapons is likely to be much greater than earlier estimates. click here to read the story 11:18
