This study provides the first in-depth analysis of sediment contamination in Ukraine’s Kakhovka Reservoir after the destruction of the Kakhovka Dam in June 2023. Clean Air for Ukraine collected samples from 11 sites in the former reservoir bed and, using advanced chromatography and mass spectrometry, identified high concentrations of PCBs, PAHs, PBDEs, PFAS and heavy metals such as arsenic, zinc, chromium and lead. In several locations, contaminant levels exceeded EU environmental quality standards, pointing to both legacy and conflict-related pollution.
The findings raise serious concerns about long-term ecological and human health risks from the remobilization of toxins into surrounding water systems. They highlight the importance of sediment monitoring as a tool to track persistent organic pollutants (POPs) under Article 6 of the Stockholm Convention and to guide strategies for environmental recovery in post-conflict areas.
The report is intended for Stockholm Convention Contact and Focal Points, national officials and experts updating NIPs or managing hazardous chemicals and waste, members of NIP coordination bodies, regional centres and other relevant stakeholders engaged in chemicals management and post-conflict environmental assessment.
