Abstract: This paper deals with the particulate matter in the surroundings of surface mining and flotation tailings Veliki Krivelj and Cerovo in Serbia measuring sites in the period from 2010 atmospheric deposition rates, pH values concentrations of sulfate, zinc, arsenic, lead were examined. Analysing the average annual deposition rate of the for three years, it was found that there was no significant exceeding of the maximum allowable value, while the maximum monthly atmospheric deposition rates were generally higher during the summer months. Higher concentrations surroundings of the mine complex Cerovo and Veliki Krivelj, while the concentrations of arsenic and zinc were increased in the vicinity of the quarry, Zagrađe, as well as in Veliki Krivelj and Cerovo. Lead, cadmium and nickel in the atmospheric depositions, during the observation period did not exceed the limit values. Keywords: Total Atmospheric Deposition, Open Pit, Cadmium, Arsenic, Lead Sažetak U ovom radu određivane su taložne Krivelj i Cerovo u Srbiji, kao i na pravcu dominantnih vjetrova, na 17 mjernih mjesta u vremenskom periodu od 2010 - 2012 godine. Ispitivane su srednje godišnje i taloženja ukupnih taložnih tvari mjesečne koncentracije sulfata, cinka, arsena, olova, kadmija i nikla iz taložnih srednjih godišnjih brzina taloženja ukupnih taložnih značajnijih prekoračenja maksimalno dozvoljene vrijednosti, dok su maksimalne mjesečne brzine taloženja uglavnom bile povećane tokom ljetnih mjeseci. Veće koncentracije sulfata u taložnim tvarima bile su u blizini rudničkih kompleksa Cerovo i Veliki Krivelj, dok su koncentracije arsena i cinka bile povećane u blizini kamenoloma, odlagališta Borskog kopa, krečane u Zagrađu, kao i u Velikom Krivelju i Cerovu. Olovo, kadmij i nikal u taložnim nisu prelazile graničnu vrijednost Ključne riječi: ukupne taložne MATRIB 2014 International conference on materials, tribology, recycling Vela Luka, 26 - 28 June 2014 HDMT Hrvatsko društvo za materijale i tribologiju ATMOSPHERIC DEPOSITION IN THE SURROUNDINGS OF OPEN PITS AND FLOTATION TAILINGS TVARI U OKOLINI POVRŠINSKIH KOPOVA I FLOTACIJSKIH JALOVIŠTA , Natalija Dolić2, Srećko Manasijević3, Tanja Kalinović Univerzitet u Beogradu, Tehnički fakultet u Boru, Vojske Jugoslavije 12, 19 210 Bor, Srbija Zagrebu Metalurški fakultet, Aleja narodnih heroja 3, 44 103, Sisak, Hrvatska Istraživačko razvojni institut LOLA d.o.o., Kneza Višeslava 70A, 11030 Beograd, Srbija Original scientific paper / Izvorni znanstveni rad particulate matter in the surroundings of surface mining and flotation Cerovo in Serbia, as well as in the direction of the dominant winds at 17 measuring sites in the period from 2010 - 2012 . The mean annual and maximum monthl atmospheric deposition rates, pH values, and the mean annual and ations of sulfate, zinc, arsenic, lead, cadmium and nickel from the atmospheric depositions were examined. Analysing the average annual deposition rate of the total atmospheric depositions for three years, it was found that there was no significant exceeding of the maximum allowable value, while the maximum monthly atmospheric deposition rates were generally higher during the summer months. Higher concentrations of sulphate in the atmospheric depositions were in the surroundings of the mine complex Cerovo and Veliki Krivelj, while the concentrations of arsenic and zinc were increased in the vicinity of the quarry, ore waste heap of the Bor mine đe, as well as in Veliki Krivelj and Cerovo. Lead, cadmium and nickel in the atmospheric depositions, during the observation period did not exceed the limit values
