AB  - Within the Joint Danube Survey 4 (JDS4) (2019) surface water samples
were collected at 24 localities along the Danube River and were extracted by
horizon large volume solid-phase extraction (LVSPE) technique. LVSPE
technique provided 25,000x relative enrichment factor (REF) of the river
samples. The bioactivity of the LVSPE samples was investigated employing
prokaryotic SOS/umuC assay (S9+ and S9-) and battery of bioassays
analyzing different endpoints – cytotoxicity (MTS assay), genotoxicity
(comet assay), cell cycle analyses of ZFL cells and embryo toxicity (zFET) in
eukaryotic models (zebrafish liver cell line – ZFL and Danio rerio embryos –
zebrafish). In the case of the SOS/umuC assay none of the tested samples
(REF100) has induced genotoxic effect. The cytotoxic effect was detected for
11 samples at REF100 (MTS assay). The comet assay results indicated
genotoxic potential for nine samples – one in the Upper Danube, six in the
Middle Danube and two in the Lower Danube. The most potent were
JDS4-37 and JDS4-41 samples collected at two sites in the Serbian part of
the Danube River. These samples were analyzed at REF13. The analysis of
the cell cycle was performed in the case of eight samples for which were
previously recorded genotoxic effect. For one sample (JDS4-41) was found
the G1 phase cell cycle arrest. The zFET assay was performed for all the
samples at REF100 and there was no embryo toxicity or teratogenicity
recorded. The results obtained within this study indicate a higher sensitivity
of eukaryotic models compared to prokaryotic SOS/umuC assay. Likewise, it
was found that most of the genotoxic samples originate from the middle
part of the Danube.
