20.500.12556/RUL-163515 Grey water footprint of contaminants of emerging concern from wasterwater in Sava River basin Sivi vodni odtis novodobnih onesnaževal iz odpadnih vod v porečju Save Water pollution by contaminants of emerging concern (CECs) causes risks to both the environment and human health. We assessed water pollution by CECs in the Sava River basin in two monitoring campaigns carried out in May and July 2017. The grey water footprint (GWF) is a tool that converts the level of pollution by particular substances into the volume of water needed for dilution to a harmless level. Therefore, it can serve as an indicator for comparing various pollutants. The results show that substances that determine the GWF differ in individual locations. The highest value of the GWF was associated with 17β-estradiol, however, found only in one wastewater sample. The study showed that the value of the GWF in individual locations fluctuates and does not depend on the size of the wastewater treatment plant from which the wastewater is discharged. At selected wastewater treatment plants, a sustainability assessment was carried out using the Water Pollution Level indicator. The values in all cases were below the level of 1.0, indicating sustainable discharge; only in two cases did values reach the defined threshold to question the potential of non-sustainable discharge. The study contributes to earlier studies on the GWF and enlarges knowledge regarding the GWF of CECs. Prisotnost novodobnih onesnaževal (NO) v vodi povzroča tveganje za okolje in zdravje ljudi. Onesnaženost vode z NO v porečju reke Save smo ocenjevali na podlagi dveh vzorčenj v okviru monitoringa, izvedenega maja in julija 2017. Sivi vodni odtis pretvori onesnaženost s posameznimi snovmi v količino vode, ki je potrebna za njihovo razredčenje, na neškodljivo raven. Zato lahko služi kot kazalnik za primerjavo različnih onesnaževal. Rezultati meritev kažejo, da se snovi, ki določajo sivi vodni odtis, razlikujejo od lokacije do lokacije. Najvišja vrednost sivega vodnega odtisa je bila povezana s snovjo 17β-estradiol, ki pa je bila ugotovljena le v enem vzorcu odpadne vode. Študija je pokazala, da se vrednosti sivega vodnega odtisa zelo razlikujejo od lokacije do lokacije in niso odvisne od velikosti čistilnih naprav. Za izbrane čistilne naprave je bila izvedena ocena trajnostnosti z uporabo kazalnika stopnje onesnaženosti vode. Vrednosti so bile v vseh primerih pod ravnjo 1,0, ki pomeni trajnostni izpust onesnaženja, v dveh primerih pa sta vrednosti že spadali v območje negotovosti. Študija prispeva k prejšnjim študijam o sivem vodnem odtisu in povečuje znanje o sivem vodnem odtisu pri tej vrsti onesnaženja. contaminants of emerging concern grey water footprint micropollutants Sava River basin wastewater treatment plants novodobna onesnaževala sivi vodni odtis mikroonesnaževala reka Sava čistilne naprave true false true Angleški jezik Slovenski jezik Članek v reviji 2024-10-08 11:19:04 2024-10-08 11:19:10 2024-10-22 10:17:28 0000-00-00 00:00:00 2022 0 0 Str. 117-128 no. 63 Vol. 35 Dec. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 502.51:628.32(282)(497.4) 0352-3551 10.15292/acta.hydro.2022.09 210640899 Ansorge,_Stejskalova,_Soldan-Grey_Water_Footprint_of_Contaminants_of_Emerging_Concern_from_Wasterwater_in_Sava_River_Basin.pdf Ansorge,_Stejskalova,_Soldan-Grey_Water_Footprint_of_Contaminants_of_Emerging_Concern_from_Wasterwater_in_Sava_River_Basin.pdf 1 7B75C44EAC6077DA12B65B341C1DF4C4 646e93994e239bae535e8af590e130b91df89ff1fe7f5dd7225499e03f3badf9 469a818b-8556-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=193265 https://actahydrotechnica.fgg.uni-lj.si/si/paper/a35la 1 345fbb65-8556-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=193264 Fakulteta za gradbeništvo in geodezijo 0 0 0
