“…Serbia has accepted the Urban Waste Water Treatment Directive (UWWTD 91/271/EEC) and the obligation to solve this problem, practically from the very beginning. Only 12 % of wastewater being discharged to the sewage network (which receives 58% of total municipal wastewater) is being subjected to a purification process (Marko et al, 2020). Consequently, sludge treatment considerations have not received sufficient attention yet.…”

The improvement of wastewater treatment techniques is of crucial importance for effluent quality, but it also results in an increased amount of waste sludge. Dehydrated sludge contains organic matter and nutrients, and therefore it can be used in agriculture and bioremediation, but it is considered a potential source of environmental pollution. As the sludge analyzed in the research does not contain impermissible levels of organic and inorganic pollutants, the aim of the research was to examine microbiological, particularly sanitary, aspects and potential for its further use. Microbial diversity was determined by the standard serial dilution technique and selective media, and sanitary quality indicators (total coliforms, fecal coliforms, Escherichia coli and Salmonella spp.) were determined by the MPN method. The abundance of fungi, actinomycetes, and bacteria (ammonifiers, spore-forming bacteria and Pseudomonas spp.) indicate possibilities for further use of the sludge. The chemical analysis included the following parameters: total nitrogen (N), phosphorus in the form of P2O5 (available P), organic carbon (C), C/N ratio, pH, and water content. The chemical composition indicates the potential of sewage sludge to be used as a soil fertilizer, but its C/N ratio is not adequate to enable successful conversion to biosolids by the composting process. The obtained results indicate a significant level of microbiological contamination, which was most pronounced in the centre of the stabilized sludge pile. The research showed the necessity to conduct further studies on the microbial diversity and sanitary aspects of sewage sludge for proper waste sludge management.

In situdetection of the genotoxic potential as one of the lines of evidence in the weight-of-evidence approach—the Joint Danube Survey 4 Case Study

et al. 2022

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.

Effects of sanitation on child growth in Serbian Roma communities

Poor sanitation may be associated with growth faltering, but empirical evidence on the association between household sanitation infrastructure and child nutrition has been mixed. This article assessed whether sanitation infrastructure is associated with growth penalties for Roma children. Design This is a Roma nationally representative population-based study. Proxies of child nutritional outcomes included children’s height-for-age Z scores below two standard deviations from the median of WHO’s reference population. Multiple and logistic regressions estimated the association between the type of toilet usage, outcomes, and sociodemographic determinants. Setting Data were from UNICEF’s fifth and sixth Multiple Indicator Cluster Surveys for Serbian Roma settlements. Subjects Children aged 0–24 (n = 1,150) and 25–59 (n = 2,024) months born to women aged 15–48 years were included in this study. Results About 16% of children resided in households with no toilet service, and 23% of children were stunted. Roma children aged 25–59 months in households with no toilet service and in rural areas were more likely to be stunted and of significantly shorter stature than their counterparts. Children up to 24 months of age were not affected by the type of toilet, likely due to protective effects of breastfeeding. Child’s age, number of siblings, and birth spacing negatively influenced growth outcomes, while maternal age, birthweight above 2.5 kg, and being a female mitigated against poor growth outcomes. Conclusions The relationship between the type of toilet and growth outcomes among Roma children varied with age and area: having no toilet and living in rural areas were associated with compromised child growth for children aged 25–59 months. Maternal and child characteristics additionally accounted for children’s growth.
