Contamination fears after Nord Stream blastResearchers are rushing to find out whether explosions in the Nord Stream gas pipelines in September have caused environmental damage by stirring up pollutants from discarded chemical weapons. The blasts happened very close to a Danish island that houses chemical weapons that were dumped by Germany after the Second World War. The metal casings of the warheads have probably corroded, causing the contents to leach into the sediment. Environmental scientists fear that methane expelled from the ruptured pipeline might have sent those contaminants into the water column, where they could harm marine wildlife. A team is now modelling the extent of sediment dispersal caused by the blasts, and measuring this against toxicity thresholds for marine species to assess whether they’ve been hurt. |
