Heavy metal content of pm10 and pm2.5 within urban area of Belgrade

An assessment of air quality of Belgrade was performed by determining the trace element content in airborne PM10 and PM2.5 in two years period. Samples were collected at two locations in a heavy polluted area. The concentrations of Al, Cr, Cu, Fe, Mn, Ni, Pb, V and Zn were determined with AAS. Results indicated that the ambient concentration of Zn in the PM10 and PM2.5 was the highest (1389.18 and 1998.00 ng m-3 respectively). Also, the highest enrichment factor (EF) value was obtained for Zn, folowing with high EF for Cd and Pb in PM10, reflecting the importance of anthropogenic inputs. The limit values of toxic trace elements from WHO and EC Air quality guidelines were not exceeded except for Ni.Physical chemistry 2006 : 8th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 26-29 September 200

Receptor modeling studies for the characterization of PM10 pollution sources in Belgrade

The objective of this study is to determine the major sources and potential source regions of PM10 over Belgrade, Serbia. The PM10 samples were collected from July 2003 to December 2006 in very urban area of Belgrade and concentrations of Al, V, Cr, Mn, Fe, Ni, Cu, Zn, Cd and Pb were analyzed by atomic absorption spectrometry. The analysis of seasonal variations of PM10 mass and some element concentrations reported relatively higher concentrations in winter, what underlined the importance of local emission sources. The Unmix model was used for source apportionment purpose and the four main source profiles (fossil fuel combustion; traffic exhaust/regional transport from industrial centers; traffic related particles/site specific sources and mineral/crustal matter) were identified. Among the resolved factors the fossil fuel combustion was the highest contributor (34%) followed by traffic/regional industry (26%). Conditional probability function (CPF) results identified possible directions of local sources. The potential source contribution function (PSCF) and concentration weighted trajectory (CWT) receptor models were used to identify spatial source distribution and contribution of regional-scale transported aerosols.

Evaluation of mortality attributed to air pollution in the three most populated cities in Serbia

The subject of this study was a mid-term evaluation of cardiovascular, respiratory and total non-accidental mortalities attributed to exposure to PM 10 , O 3 , NO 2 and SO 2 in the cities of Belgrade, Novi Sad and Nis, representing about 25% of the population of Serbia. The analysis was performed using AirQ+ modelling, by linking annual baseline mortality rates and daily pollutant exposure levels in 2011–2015 based on the cause-specific concentration–response functions. Estimated shares of annual mortality attributed to these pollutants, thanks to harmonizing of assessment methodologies, may stand next to and be compared with results obtained in previously conducted studies. The obtained premature deaths estimated within 95% confidence interval (in parentheses) and attributed to PM 10 , O 3 , NO 2 and SO 2 exposure were 2013 (1344–2677), 1411 (685–2086), 831 (555–1107) and 443 (333–530), respectively. Total non-accidental mortalities due to O 3 and NO 2 exposure were in the range of findings for other regions, while mortalities attributed to PM 10 were higher. It was also found that cardiovascular mortality caused by these four pollutants was higher than respiratory mortality. Based on our results, efficient implementation of abatement strategies that would reduce PM 10 , O 3 and SO 2 concentrations to daily air quality limit values set by the World Health Organization could respectively prevent, in the three cities together, about 233 (156–310), 40 (19–59) and 71 (53–85) premature deaths per year. © 2019, Islamic Azad University (IAU)

Evaluation of the levels and sources of trace elements in urban particulate matter

An assessment of air quality of Belgrade, Serbia, was performed by determining the trace element content in airborne daily PM10 and PM2.5 samples collected from a central urban area. The ambient concentrations of Zn were the highest in PM2.5 (1,998.0 ng m(-3)). Multivariate receptor modelling (principal component analysis and cluster analysis) has been applied to determine the contribution of different sources of specific metallic components in airborne particles. The obtained results showed that vehicle traffic and fossil fuel combustion in stationary objects were the main sources of trace metals in Belgrade urban aerosols

Source Apportionment of Atmospheric Bulk Deposition in the Belgrade Urban Area Using Positive Matrix Factorization

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).2nd International Workshop on Non-Equilibrium Processes in Plasmas and Environmental Science, Aug 23-26, 2008, Belgrade, Serbi
