Abstract The Joint Danube Survey 3 (JDS3; the biggest river expedition in 2013) had offered the unique opportunity for a large-scale monitoring approach for biomarker response in feral fish collected along a Danube stretch from Kehlheim (DE) to Sulina (RO). The advantage of genotoxicity as a marker for pollution exposure in fish is the early detection of possible long-term effects such as cancer. Therefore, genotoxicity was in the focus of the biomarker investigations in fish during the expedition. Blood samples of common bleak (Alburnus alburnus) for the investigation of the micronucleus frequency and comet tail intensity of fragmented DNA material in erythrocytes were collected at 18 and 12 sampling sites, respectively. For 9 sampling sites same samples were used to compare the in-situ data for the comparable genotoxic endpoint in the micronucleus (MN) and comet assay (CM). The data of both in-situ assays showed a significant correlation, indicating the strength and comparability of the data sets. Significant variation in DNA damage in fish along the longitudinal profile of the Danube was demonstrated for both assays compared to reference sites. The results suggest that DNA damage in erythrocytes of fish was mainly affected by wastewater of highly populated regions. No linkage between the results and the general health/dietary status of the fish were revealed, whereas correlation with some genotoxicity drivers in the water phase, suspended particulate matter and sediments could be demonstrated.
