AB  - Environmental studies which aim to assess the ecological impact of chemical and other types of pollution should employ a complex weight-of-evidence approach with multiple lines of evidence (LoEs). This study focused on in situ genotoxicological methods such as the comet and micronucleus assays and randomly amplified polymorphic DNA analysis as one of the multiple LoEs (LoE3) on the fish species Alburnus alburnus (bleak) as a bioindicator. The study was carried out within the Joint Danube Survey 4 (JDS4) at nine sites in the Danube River Basin in the Republic of Serbia. Out of nine sampling sites, two were situated at the Tisa, Sava, and Velika Morava rivers, and three sites were at the Danube River. The three additionally employed LoEs were: SumTUwater calculated based on the monitoring data in the database of the Serbian Environmental Protection Agency (SEPA) (LoE1); in vitro analyses of JDS4 water extracts employing genotoxicological methods (LoE2); assessment of the ecological status/potential by SEPA and indication of the ecological status for the sites performed within the JDS4 (LoE4). The analyzed biomarker responses in the bleak were integrated into the unique integrated biomarker response index which was used to rank the sites. The highest pollution pressure was recorded at JDS4 39 and JDS4 36, while the lowest was at JDS4 35. The impact of pollution was confirmed at three sites, JDS4 33, 40, and 41, by all four LoEs. At other sampling sites, a difference was observed regarding the pollution depending on the employed LoEs. This indicates the importance of implementing a comprehensive weight-of-evidence approach to ensure the impact of pollution is not overlooked when using only one LoE as is often the case in environmental studies.

AB  - Background: Montenegro is characterized by numerous mountain springs and larger streams. Many of them are used as sources of drinking water, irrigation, but also for tourists’ recreation: kayaking, rafting, etc. Unfortunately, there is a lack of wastewater treatment plants as well as information about microbial water quality of many surface and ground waters.
Objectives: Taking into consideration issue of scarce data about microbial water quality, the aim of this study was to locate hotspots of faecal pollution and investigate the source of pollution. Within the study, 25 sites were selected while three of them were not included in National monitoring program.
Methods: To quantify the most probable number of Escherichia coli we used Colilert-18 System. The water quality based on this parameter was assessed according to Kirshner et al. (2009). For determination of the pollution origin, microbial source tracking method was employed. Indicators of human faecal pollution, markers BacHum and HF183II, and animal faecal pollution, markers BacR and Pig2Bac, were quantified with qPCR.
Results: According to most probable number of E. coli, 40% sites were little polluted, 36% moderately, 16% critically and per 4% heavily and excessively polluted. Analysis of genetic faecal markers indicated the prevalence of human-as- sociated faecal pollution at all sites. Considering the results of the study, four sites were classified as hotspots of faecal pollution: downstream Pljevlja (Ćehotina River), downstream Vezišnica (Ćehotina River), wastewater outlet at Podgori- ca (Morača River), and downstream Bijelo Polje (Lim River).

AB  - Untreated municipal wastewaters are one of the major negative contributors on freshwater quality, and consequently on ecosystem balance. Some compounds such as pharmaceuticals, cosmetic products, etc. could be genotoxic and lead to somatic and/or germinative mutations. This mutation should be reflected on organisms’ health and reproductive potential. Comet assay is a widely used test in ecogenotoxicology for detection of primary DNA damage. In that way, this sensitive test could provide information about early warning signs of potential stressors effects before those have an impact on the population or ecosystem level.
The scope of our study was to assess the level of DNA damage of Alburnus alburnus specimens’ gill cells and erythrocytes. Three sites on the Sava river were chosen: reference site Zabran suited upstream the municipal discharging; second at the confluence of the Kolubara river and the Sava river; and the third at the confluence of the Barička river and the Sava river. The Kolubara river and the Barička river are chosen as important recipients of untreated wastewaters. From each site, 5 bleak specimens were collected and blood and gills were taken. Tail Intensity (TI%) was chosen as a parameter for evaluating the level of DNA damage. Besides that, cell viability and extremely damaged cells - hedgehogs (HH) were determined.
The significant difference in TI% values was recorded in erythrocytes and gills cells in comparison between the Zabran (TI%=14.01±0.61 in erythrocytes, TI%=15.25±1.03 in gills cells) and the second site (TI%=18.53±0.65 in erythrocytes, TI%=22.78±1.89 in gills cells). Correlation between cell viability and HH frequency was not observed. According to the results, we could conclude that the second site is the most affected by pollutants. Also, usage of comet assay on freshwater organisms could be appropriate for preliminary screening of ecosystem state.
