Izvod Rudarstvo i proizvodnja bakra u Boru, tokom proteklih sto godina, imalo je ogroman uticaj na životnu okolinu. Otpadne vode koje se generišu u pogonima RTB Bor zagađuju Borsku i Kriveljsku reku koje predstavljaju otvoreni kolektor za otpadnu vodu. Posle uliva Borske reke u Kriveljsku reku nastaje Bela reka koja se dalje uliva u reku Timok, odnosno reku Dunav. Za period istraživanja od 17. oktobra 2012. god. do 17. januara 2013. sprovedena je analiza rudničkih, drenažnih i komunalnih otpadnih voda. Za potrebe istraživanja i procenu negativnog uticaja otpadnih voda na površinske vode na terenu je sprovedeno merenje protoka, temperature, pH vrednosti, oksido/redukcionog potencijala i koncentracije rastvornog kiseonika u uzorcima vode. Takođe, određen je i sadržaja Cu, Fe 2+ , ukupnog Fe (T-Fe), As, Mn, Si, Ni i Al.
In recent years quality control has received a great attention in laboratory work. Implementation of the international standard ISO/IEC 17025 is necessary for any laboratory that wishes to establish quality control in its work. One of the important factors for meeting the requirements of this standard is the usage of the certified reference materials (CRM) in laboratory work. In order to determine the performance of the calorimeter, benzoic acid as CRM, from AlliedSignal Riedelda Haen, Ref.: 33045 and SiO2, Pro analyze, in various mass ratios was used. The results showed that benzoic acid can be successfully utilized for the control of the entire technical and instrumental measuring range and resolve the problem of determination of the limit of detection and quantification of the calorimeter
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
