  • An unidentified highly toxic substance in the Oder River, which runs through Poland and Germany, appears to be the cause of a mass die-off of fish, the German state of Brandenburg’s environment ministry said on Friday (12 August).
  • The state laboratory found high levels of mercury in the water samples.
  • In a public warning this week, residents in the Uckermark and Barnim districts, home to rolling hills and a nature reserve, were advised to avoid contact with water from the Oder and an adjacent canal.
