Field application of hydrogen peroxide to prevent the spread of Prymnesium parvum to the Oder River: efficacy and ecological safety assessment

Key Points

• The aim is to evaluate the effectiveness of hydrogen peroxide in preventing the spread of Prymnesium parvum in the Oder River while assessing its ecological safety.
• Applied hydrogen peroxide at doses of 10–15 mg H2O2/L to assess efficacy against Prymnesium parvum
• Monitored effects on non-target organisms
• Conducted systematic efficacy and safety assessments
• Hydrogen peroxide eliminated 90–99% of Prymnesium parvum cells
• Demonstrated acceptable effects on non-target organisms
• Supported the ecological safety of using hydrogen peroxide to reduce bloom dispersal
