Therefore the aim of this research was to determine the tolerance of plant growth and development of Berberis thunbergii DC. (Japanese barberry) to irrigation with greywater (GW) and to examine changes in chemical properties of soil. The two-year experiment, conducted during vegetation season, was comprised of the following treatments: K (control, 100% DW), T1 (diluted GW containing 50% DW and 50% GW), T2 (100% GW) and T3 (alternating watering with 100% DW and 100% GW). After statistical analyses, the results indicate the similarity between the K and T3 treatments in terms of the plant growth and development of new shoots. T1 treatment leads to slower plant growth, whereas T2 treatment leads to slower development of new shoots, but the vitality of the plants was not observed. Application of T1, T2 and T3 treatments resulted in slight salinisation of the soil. In general, the results of this research indicated that GW can be used for irrigation of B. thunbergii, preferably with the application of alternating watering T3 treatment.

Degradation of water quality caused by an anthropogenic influence is a problem which is present even at some special nature reserves (SNRs) in the Province of Vojvodina, Serbia. The aim of this paper is to present results of preliminary research on water quality on three SNRs. Whereas in the SNR Ludaško jezero (Ludaš Lake) and in the SNR Obedska bara (Obedska Pond) serious euthropic processes are present due to agricultural runoff and untreated wastewater, the SNR Stari Begej-Carska bara (Old Bega River-Imperial Pond) is under the potential influences of fish farms and agriculture. The monitoring conducted in spring/summer period and in autumn in all SNR included water sampling on several locations within each SNR. The analyses included basic water quality parameters, water mineralization and microbiological analyses. Both, water quality and microbiological results have proven highly eutrophic status of the SNR Ludaško jezero and significant difference in salinity in the north and in the south of the lake. The results on the other two investigated SNRs are a bit better indicating moderate eutrophic conditions, except for autumn sampling at SNR Stari Begej-Carska bara when serious deterioration of water quality was determined.

False indigo‐bush (Amorpha fruticosa L.) is a plant native to North America but has intentionally or unintentionally spread over the Northern Hemisphere, where it often becomes invasive. The plant is especially easily dispersed within the watersheds of large rivers, where seasonal flooding is regular. Seeds and other propagules are buoyant, and when the water recedes, new plants emerge, forming dense thickets where only a few other species can co‐exist. In order to sustain native biodiversity, spread control is needed. However, mechanical control and eradication measures currently in use are labor demanding and costly, while application of herbicides is limited. On the other hand, the plant possesses a number of beneficial properties, such as phytochemical applications (medical and insecticidal effects), biocoenotic uses (honey plant, ornamental features), and ecosystem services (soil stabilization, provision of food for animals, and fiber and biomass for industry, e.g., nanocellulose). For the reasons above mentioned, the plant is considered quite controversial, and the paper discusses both aspects: potential detrimental effects when introduced to new habitats and its beneficial uses for human society. In addition, the paper presents alternative measures of spreading control (e.g., grazing) and argues that exploiting it for beneficial purposes might help spread control, thus covering the expenses of controlling its distribution.

The second question is about the survival of coronavirus in drinking water. 1 Material and methods The role of water is immense, in particular as it serves as a universal solvent for various substances of inorganic and organic origin from both natural or/and human-made sources. It circulates not only through the hydrological cycle, but also fl ows through living organisms (Grabić et al., 2020), simultaneously contributing to diverse interactions with living-non-living nature. This complex role of water, which includes the impact of human societies and economies, is presented in Fig. 1. This implicates diff erent or even contradictory roles of water, i.e. clean water vs. polluted water. Especially during the COVID-19 pandemic, water has a dual role. Its positive role is, in the fi rst place, clean drinking water, which keeps supporting general health and good immunity. Another role is keeping hygienic conditions and diluting pollutants. Clean water is an essential raw material for the production of various goods (disinfectants, drugs, etc.) necessary in the fi ght against COVID-19, as well as for the production of safe food (Grabić et al., 2020). On the other side, the negative role of water and waterbased body fl uids (e.g. saliva, urine, blood) during the COVID-19 pandemic is the ability to carry and spread undesired compounds, in this case, coronavirus. It is confi rmed that the most common way of spreading

The common reed Phragmites australis, naturally growing at the CW location, was used as biofiltering vegetation. The monitoring effectiveness of the CW was based on removing suspended solids and reducing the amount of organic matter. The eight-year long study shows that the age of the constructed wetland does not significantly affect the changes (increase) in concentration of suspended particles and organic compounds from the wastewater effluent. We proved that measured values of variables, suspended solids, and biochemical oxygen demand (BOD 5) of effluent belong to the same population. The chronological data series of suspended solids and BOD5 of effluent were processed using statistical tests of homogeneity, both parametric (Student's t-test with Fisher's F-test) and nonparametric (Mann-Whitney's U-test). The results of testing homogeneity of the data confirm that the constructed wetland has not been compromised, and that the removal of suspended solids is 93-96% and reduction of organic compounds, expressed in terms of BOD 5 , is up to 79-84%.

The improvement is reflected in the grouping of scattered and distributed agricultural allotments into larger parcels. New plots are of regular shape, suitable for the application of modern agricultural machinery, with direct access to the network of field roads. In order to form suitable plots in grouped ownership it is necessary to perform clearcutting of almost all forms of non-forest greenery, because it represents an obstacle for land consolidation. The presence of non-forest vegetation in the area with a large percentage of arable farmland is of great importance. Functions of nonforest greenery are reflected in the protection of soil from drying out and wind erosion, conservation of biodiversity and landscape outlook. This paper presents the possibility of determining the presence and connectivity of non-forest vegetation using Google Earth satellite imagery. Identified areas under non-forest vegetation are classified as point, line and surface elements. Presence, interconnectivity and spatial distribution of non-forest vegetation have been determined by using a geographic information system on land consolidated area of the municipality of Ada. The state that was registered using satellite images was compared to the condition which would be obtained after the realisation of a project of establishing windshield belts.

The paper aims to develop a new improvised water quality indicator using statistical methods. To reduce the number of analysed chemical parameters and simplify the tests, WQI min was used. The results of the research conducted in Serbia in 2019 were subjected to correlation and principal component analysis (PCA). This reduced the number of parameters from 29 to 8, significantly reducing the time and cost of laboratory analyses. The temporal and spatial variability evaluation can be performed using WQI min , which consists of dissolved oxygen, total phosphorus, orthophosphate, total dissolved solids, suspended solids, chlorides, ammonium, and nitrite nitrogen. The main sources of river contamination were untreated industrial sewage, fish farming wastewater, and soil erosion. The highest level of pollution was observed in winter. Good water quality was found in the river's upper course and very good in the lower course. Water quality values obtained based on a complete and simplified set of parameters were strongly correlated with each other.

Serbia is among many European countries with a growing interest for the implementation of the NbS. This paper presents the results of assessment of two rain gardens (RGs) taken as case studies, implemented as some of the first examples of NbS. The research methodology is based on evaluation of the hydrologic effectiveness through continuous visual inspection during the period after RGs construction in the first year, second and third year after RGs establishment. Visual inspection involved observations of the basic functions of RGs i.e. flow reduction during storm events, presence of standing water or overflows, time of infiltration, vegetation health and establishment. Mentioned items were monitored in order to understand the performances and test the functionality of RGs due to their further implementation. Findings based on visual ass...

In this study, we simulated bioretention performances for four locations in the city of Novi Sad, with RECARGA modelling software. The primary objective of the research was to evaluate potential of bioretention systems for runoff reduction. The second research objective was to suggest RECARGA model as a support for future decision-making processes. Analysis of the sensitivity of bioretention design parameters on bioretention performances, involved variations related to different sizes of bioretention systems, application of an underdrain, the difference in soil texture and changes in the depth of each individual bioretention layer. The total average volume of retained runoff by bioretention systems ranged from 43.33 to 93.84%, while some single simulation results were 100%. Among all tested design parameters, bioretention size and the native soil hydraulic conductivity have shown the greatest...

Among numerous issues, wastewater purification represents a significant request. To achieve the goal of discharging good-quality water into natural water bodies as recipients, various methods have been used. The method of constructed wetland (CW) is based on wastewater purification by using wetland plants. The method of CWs shows the best results for small settlements for up to 5,000 inhabitants and can be nicely integrated within the landscape of a plain where waterbodies’ banks are overgrown by wetland plants. Such facilities have been used for decades in the territory of the EU, and only a few have been built in the Republic of Serbia. Since the Republic of Serbia is a candidate country for the EU, there is a strong intention to take action focused upon solving wastewater purification from various so...
