After the Oder fish kill: Poland fights the spread of the toxic golden algae

Poland is taking emergency measures to combat the toxic golden algae bloom in the Oder and Gleiwitz Canal. The use of hydrogen peroxide has been effective in destroying 90-99.9% of the algae cells.

However, this is only a temporary solution, and Poland is working on long-term plans to reduce pollution, particularly from salt mining. Last summer, efforts were made to oxygenate the water.

The Gleiwitz Canal, which has been in operation since 1939, is a significant area affected by the algae bloom. The recent fish kill in the Oder river has been attributed to the toxic effects of the golden algae Prymnesium parvum.

Poland's authorities are committed to preventing further fish kills and are in talks with Germany, as Poland plans to expand the Oder river.

Poland Fights Against the Spread of the Toxic Golden Algae

Environment

After the fish die-off in the Oder, Polish authorities are combating the toxic golden algae with hydrogen peroxide. The algae is spreading in tributaries like the Gliwice Canal and the Dzierzno Duze reservoir, where tons of dead fish have been recovered. The introduction of hydrogen peroxide effectively destroys the algae cells, but it is only an emergency measure. Poland is working on a plan to reduce the salt discharges from mining to reduce the long-term pollution of the waters.

Poland Fights Spread of Toxic Golden Algae

Environment

Poland is fighting toxic golden algae in the Oder River tributaries with hydrogen peroxide; the algal bloom led to an environmental disaster with massive fish deaths in 2022; authorities recovered tons of dead fish from the Gleiwitz Canal and the Dzierzno Duze reservoir; work is underway to reduce pollution, especially brine discharges from mining; oxygen enrichment in the 41-kilometer-long Gleiwitz Canal, which connects the city of Gleiwitz (Gliwice) to the Oder, was already ordered in 2022.
