AB  - Natural uranium, consisting of 238U, 234U and 235U isotopes is present in the environment in low
concentrations especially in the atmosphere where it usually exists as a constituent of particulate
matter submicron conglomerates suspended in the air. In the case of contamination, uranium may be
present in the aerosol, being transferred to other areas by wind and again settled on the surface soil
with possible migration into deeper layers or resuspension under certain meteorological conditions.
Here results on the airborne uranium assessment based on the analysis of lichen species already
present or transplanted into contaminated areas will be presented. With that aim, different in situ
and transplanted epiphytic lichen species have been taken at selected locations in southern Serbia in
the stage of existing contamination by depleted uranium, during the clean-up activities and
afterwards, in all four seasons. Collected samples underwent analysis by sensitive nuclear analytical
techniques. The INAA and ICP MS results are derived from 238U mass fraction while high resolution
alpha-spectrometry gave results for each isotope expressed as specific activity concentration
(Bq kg-1). Based on the isotopic ratios 235U /238U and 234U /238U, depleted uranium content was
possible to distinguish from natural uranium in the samples. Results have shown that the sensitivity
of the examined morphologically different lichen types and their ability to accumulate metals
including uranium, strongly depend on metals’ concentration in the air as well as on the age of
lichens, properties of host species, chemical properties of particles, local climate conditions, exposure
time etc. Epiphytic lichen species Evernia prunastri was found to be the most suitable bioindicator
for the accumulation of uranium airborne particles. Concerning the uranium content, a significant
difference in concentrations had been observed for different sampling phases, with maximum
depleted uranium contribution during the clean-up activities. The variability in uranium
concentrations was noticeable in relation to prevailing wind direction, position and distance of the
sampling points. Having in mind the results obtained within the national radioactivity monitoring
program 2011-2017, it may be concluded that for detailed airborne uranium assessment, a
methodology such as biomonitoring with the application of sensitive nuclear techniques should be
considered.

AB  - The primary objective of this study is to assess anthropogenic impacts on the environment by determination of element atmospheric depositions. Bulk depositions were collected monthly, from June 2002 to December 2006, at three urban locations in Belgrade. Concentrations of Al, V. Cr, Mn, Fe, Ni, Cu, Zn, Cd and Pb were analyzed by atomic absorption spectrometry and the current deposition fluxes of atmospheric metals were established. Fourier analysis was applied in order to investigate seasonal variation of the monthly data set. Nickel, V. Fe and Al showed pronounced seasonal dependence, while seasonal variation of the other elements was not evident. The enrichment factors of Pb. Zn, Cd and Cu were obviously above those who could have been caused by natural processes, indicating a mainly anthropogenic origin. Nickel was intermediately enriched suggesting participation of both natural and anthropogenic sources. The multivariate receptor model, Unmix, was used to analyze a 5-yr element atmospheric depositions data set. Three main source profiles (mixed road dust, oil combustion and metal processing) were identified and the overall average percentage source contributions determined. (C) 2010 Elsevier Ltd.

AB  - The primary objective of the present study was to assess anthropogenic impacts of heavy metals to the environment by determination of total atmospheric deposition of heavy metals. Atmospheric depositions (wet + dry) were collected monthly, from June 2002 to December 2006, at three urban locations in Belgrade, using bulk deposition samplers. Concentrations of Fe, Al, Pb, Zn, Cu, Ni, Mn, Cr, V, As and Cd were analyzed using atomic absorption spectrometry. Based upon these results, the study attempted to examine elemental associations in atmospheric deposition and to elucidate the potential sources of heavy metal contaminants in the region by the use of multivariate receptor model Positive Matrix Factorization (PMF).
