Groundwater is an important natural resource.The analysis of groundwater quality is necessary to maintain and preserve the entire ecosystem. On a thermal energy facility, during regular water quality control, an increased concentration of organic pollutants has been observed. The aim was to analyze petroleum hydrocarbons and their derivatives, before and after cleaning treatments. The application of microbiological and physical-chemical treatments, organic pollutants were removed from all microlocations, more than 96 %. Podzemne vode su važan prirodni resurs. Analiza kvaliteta podzemnih voda je neophodna za održavanje i očuvanje čitavog ekosistema. Na termoenergetskom objektu, tokom redovne kontrole kvaliteta vode, uočena je povećana koncentracija organskih zagađujućih supstanci. Cilj ovog rada bio je ispitivanje i praćenje stepena zagađenja podzemnih voda i efikasnost tretmana, koji je korišćen za uklanjanje zagađujućih supstanci. Primena mikrobioloških i fizičko-hemijskih tretmana, organski zagađivači su uklonjeni sa svih mikrolokacija, više od 96 %. Related to: [http://cer.ihtm.bg.ac.rs/handle/123456789/3306]

Zagađenje vode, zemljišta i sedimenta naftom i njenim derivatima, može se javiti tokom eksploatacije, transporta i skladištenja i predstavlja rizik za životnu sredinu i ljudsko zdravlje. Bioremedijacija je zelena tehnologija kojom se uklanja zagađenje iz kontaminirane životne sredine upotrebom mikroorganizama. U ovom radu su praćene promene u sadržaju mineralnih ulja i aktivnost mikroorganizama koji razgrađuju ugljovodonike tokom procesa bioremedijacije koji je trajao 210 dana. Rezultati ukazuju da mikroorganizmi koji razgrađuju ugljovodonike sa visokom efikasnošću degraduju mineralna ulja. Na osnovu količine mineralnog ulja (smanjena za 63,82 %), stepena degradacije i udela mikroorganizama naftnih degradera u ukupnom broju mikroorganizama, može se zaključiti da su faza adaptacije konzorcijuma i faza intenzivne razgradnje bile u periodu od 0. do 90. dana, praćene dalje sporijom fazom razgradnje u periodu od 90. do 210. dana. Pollution of water, soil and sediment with petroleum and its products may occur during the exploitation, transportation and storage and it poses a risk to the environment and human health. Bioremediation is a green technology that can remove pollution from contaminated environment using microorganisms. In this paper changes in the content of mineral oil and the activity of hydrocarbon degraders during remediation process that lasted 210 days were monitored. The results indicate that hydrocarbon degrading microorganisms with high efficiency have biodegraded mineral oil. Based on the amount of mineral oil (decreased for 63.82 %), degradation rates and level of hydrocarbon degraders in the total number of microorganisms, we note that the stages of adaptation of the consortium and intensive degradation phases were in the range of 0-90 days, followed by a slower decomposition phase in the period of 90-210 days.

Air pollution is an important risk factor for health in Europe and worldwide. This paper presents the quality of air in the territory of the town of Šabac during 2018. The measured values of SO2 and NO2 were less than the legally permitted limit, but the concentration of soot was above the limit of 50 μg/m3 for 15 days during the examined period. The study of air quality in urban and industrial areas is very important, because it enables us to determine the degree and trend of pollution, with the aim of reducing the content of harmful substances in a time manner. Zagađen vazduh predstavlja značajan faktor rizika za zdravlje ljudi širom sveta. U ovom radu je prikazan kvalitet vazduha na teritoriji grada Šapca tokom 2018. godine. Dobijeni rezultati pokazuju da su koncentracije SO2 i NO2, bile ispod zakonom propisanih vrednosti, dok je koncentracija čađi 15 dana tokom godine bila preko maksimalno dozvoljene koncentracije. Proučavanje kvaliteta vazduha u urbanim i industrijskim područjima ima za cilj kontrolu i utvrđivanje stepena zagađenosti vazduha, kao i utvrđivanje trenda zagađenja, kako bi se pravovremeno delovalo ka smanjenju sadržaja štetnih supstanci Related to: [http://cer.ihtm.bg.ac.rs/handle/123456789/3304]

Adsorption is one the best commonly used technique for treatment of petroleum contaminated water. The biosorption potential of waste biomass (peach shell, agro-industrial waste) as a low-cost biosorbent for petroleum hydrocarbon from aqueous solution was explored. Biosorption experiments were carried out using a shake-flask technique with a constant amount of (bio) sorbent of 1 g mixed with 100 ml of water contaminated with petroleum hydrocarbons at concentrations of 4 mg/L, 12 mg/L, 18 mg/L, 24 mg/L, 30 mg/L, 40 mg/L and 80 mg/L. The obtained results show that waste biomass is efficient in the removal of petroleum pollutants from the water solution. Biosorption is a potentially alternative technique for wastewater treatment. Their major advantages are low cost, high efficiency, renewability. Adsorpcija je jedna od najčešće korišćenih tehnika za tretiranje voda zagađenih naftom i njenim derivatima. U radu je ispitivana mogućnost primene otpadne biomase (koštice breskve, agroindustrijskog otpada), kao jeftinog biosorbenta, za uklanjanje nafnih zagađivača iz vodenog rastvora u stacionarnim uslovima. Biosorpcioni eksperimenti su obavljeni u erlenmajerima na na orbitalnom šejkeru u kojima je konstantna količina biosorbenta od 1 g mešana sa 100 ml vode kontaminirane naftnim ugljovodonicima u koncentacijama 4 mg/L, 12 mg/L, 18 mg/L, 24 mg/L, 30 mg/L, 40 mg/L and 80 mg/L. Dobijeni rezultati pokazuju da je otpadna biomasa efikasna u uklanjanju naftnih polutanata iz vodenog rastvora. Biosorpcija je potencijalno alternativna tehnika za prečišćavanje otpadnih voda. Njene glavne prednosti su niska cena, visoka efikasnost i obnovljivost. Related to: [https://cherry.chem.bg.ac.rs/handle/123456789/5411]
