AB  - The health effects attributed to exposure to ambient PM2.5 concentrations
above 10 μg/m3
by using the AirQ+ modeling software were assessed. The
hourly concentrations of PM2.5 were collected from 13 air pollution
monitoring stations in the Belgrade district during Jun and July 2021.,
which were further used as input data for the AirQ+
software. The average
concentration of PM2.5 for two-month monitoring from all sampling sites in
the city was 14.8 μg/m3
, the maximum daily concentration was 55.7 μg/m3
,
while the maximum concentration per hour was 365 μg/m3
. The spatial
distribution of concentrations was mapped using geostatistical interpolation,
revealing hotspots within the city centre and industrial area of the district.
The burden of disease, such as stroke, ischemic heart disease (IHD), chronic
obstructive pulmonary disease (COPD) and lung cancer (LC), due to the
ambient PM2.5 pollution was evaluated according to the WHO methodology
for health risk assessment of air pollution. The model used for this
assessment is based on the attributable proportion defined as the section of
the health effect related to exposure to air pollution in an at-risk population.
The estimated attributable proportion was 19.4% for stroke, 27.2% for IHD,
15.3% for COPD and 9.0% for LC. The estimated number of attributable
cases per 100,000 population at risk, due to PM2.5 air pollution, for stroke,
IHD, COPD, and LC, was 28, 34, 15, and 8, respectively.

AB  - Twenty-four hour measurements of PM2.5 particulate matter have been carried out during the period between the 22nd January
and the 25th February 2013 in a suburban area of Belgrade. PM2.5 samples were collected on 47 mm filters, with the use of
Sven Leckel gravimetric samplers, while a meteorological station recorded meteorological data nearby the sampling
instrumentation. The daily average PM2.5 concentrations were in the range of 7,05 μg m-3
to 76,43 μg m-3
. Wind direction in
combination with wind speed is an important factor for pollutant transportation, dispersion and accumulation. A correlative
analysis was used to investigate the relationship among PM2.5 concentrations and meteorological parameters (i.e. wind speed).
A negative correlation between wind speed and the concentration of PM2.5 was observed based on the measurements: lower
particle concentrations were registered at higher wind speeds.

AB  - Natural minerals, such as quartz, clinoptilolite and calcite, are useful as sorbents for various applications, but their content of heavy metals ions is the most problematic obstacle to their application. Before their (re)use, the minerals must be purified. In this work, the subject was desorption of lead from a natural multi-component mineral sample consisting of a mixture of silicates (mainly quartz and clinoptilolite) and calcite formations. Besides deionized water, different extraction solutions were tested: NaCl, KCl, CaCl2, MgCl2, HCl, HNO3, EDTA, EDTA/HCl, EDTA/NaOAc-HOAc, HOAc, NaOAc and NaOAc-HOAc. Several parameters were varied in order to obtain the optimal conditions for the desorption process: the concentration of the extraction solution, the ratio of the mass of the sample and volume of the extractant, and the pH value of the suspension. The best purification effect in one desorption cycle was obtained when 0.1 M EDTA, at a pH value of 3.5 (0.2 M EDTA was mixed with 0.01 M acetic buffer, at pH value 3.0, in ratio 1:1) was applied. Sequential extraction (5 consecutive iterations) was performed to provide a more efficient purification process. The lead content (58.20 mg/kg) was decreased by: 20% (using HOAc), 21% (using EDTA) and by more than 50% (using EDTA/NaOAc-HOAc). The pH value and conductivity were measured at all critical points to clarify the mechanism of the desorption process. The formation of Pb-EDTA complex is the result of two parallel phenomena, complexing and ion-exchange. An enhanced adsorption capacity and an improved microelement profile for the purified samples were also attained. The mineralogical and radiochemical performances of the sample were determined by the X-ray diffraction and gamma spectrometry techniques. Microelement analyses of the native and purified samples were performed by inductively coupled plasma optical emission spectroscopy (ICP-OES).

The mineralogical and radiochemical performances of the sample were determined by the X-ray diffraction and gamma spectrometry techniques. Microelement analyses of the native and purified samples were performed by inductively coupled plasma optical emission spectroscopy (ICP-OES).",

AB  - Among radionuclides in the soil deposited after Chernobyl accident, Cs-137 poses considerable environmental and radiological problemdue to its relatively long half-life (30.17 gamma), its abundance in the fallout, high mobility and similarity to potassium as the major plant nutrient. In this study the samples of undisturbed surface soil (n = 250) were taken from 70 regions in Belgrade, during 2006-2010. The specific activities of Cs-137 were measured by gamma-ray spectrometry. Based on obtained results, the external effective dose rates were calculated according to the internationally accepted activity to dose rate conversion equations. The specific activities of Cs-137 were geographically mapped. The presence of Cs-137 has been detected in all soil samples, with high variability of its specific activity, ranging from 3 to 87 Bq kg(-1).The mean specific activity of Cs-137 was 23 Bq kg(-1) and the corresponding absorbed dose was 1.5 nSv h(-1). The observed range reflects the inhomogeneity of the deposition process following the Chernobyl accident. It could also be attributed to topographic differences and spatial differences in physicochemical and biological soil properties, soil type and vegetation cover. The results of the present study could be valuable database for future estimations of the impact of radioactive pollution.

AB  - The term dioxins is commonly used to refer to group of polychlorinated organic compounds, that includes 75 congeners of dibenzo-p-dioxins (PCDDs) and 135 congeners of dibenzo-furans (PCDFs). They are classified as the most dangerous environmental pollutants of today, caused by anthropogenic activity. They occur in various industrial processes, and the main sources of dioxins are waste incinerators, power plants and heating systems, production of paper, steel and other metals. Once emitted PCDD/DFs do not stay in one medium, but are transferred and transformed. The mobility of these toxic compounds directly represents a risk to the environment and human health. The aim of this paper is to analyze the potential sources of pollution and to display the distribution of dioxins in different environmental media, with special emphasis on soil. In soil, dioxins are exposed to the processes of adsorption, diffusion and evaporation. Because of their lipophilicity, dioxins are adsorbed to organic matter and thus immobilized on the surface of the soil. The higher content of organic matter in soil - the diffusion is slower, and the highest concentration of dioxins at the surface. Dioxins are chemically very stable and are subject mainly to photochemical and, to a lesser extent, microbiological degradation. Due to the low biodegradability, they are included in polluting organic substances called persistent (persistent organic pollutants, POPs).
AB  - Pod terminom dioksini obično se podrazumeva grupa polihlorovanih organskih jedinjenja, koja sadrži 75 kongenera dibenzo-p-dioksina (PCDDs) i 135 kongenera dibenzo-furana (PCDFs). Svrstavaju se među najopasnije ekološke polutante današnjice, uzrokovane antropogenom aktivnošću. Nastaju u različitim industrijskim procesima, a glavni izvori emisije dioksina su: insineratori otpada, energetska postrojenja i sistemi za grejanje, proizvodnja papira, čelika i drugih metala. Nakon emisiije PCDD/DFs se ne zadržavaju se u jednom medijumu, već se prenose i transformišu. Mobilnost ovih toksičnih jedinjenja direktno predstavlja rizik po životnu sredinu i zdravlje ljudi. Cilj ovog rada je da se analiziraju potencijalni izvori zagađenja i prikaže raspodela dioksina u različitim medijumima okoline, sa posebnim osvrtom na zemljište. U zemljištu, dioksini su izloženi procesima adsorpcije, difuzije i isparavanja. Zbog svoje lipofilnosti, dioksini su adsorbovani za organsku materiju i na taj način imobilisani na površini tla. Što je veći sadržaj organske materije u tlu - difuzija je sporija, a koncentracija dioksina najveća na površini. Dioksini su hemijski vrlo stabilni i podležu pretežno fotohemijskoj i, u manjoj meri, mikrobiološkoj razgradnji. Zbog niske biodegradabilnosti, ubrajaju se u zagađujuće organske supstance koje nazivamo postojanim (eng. persistent organic polutants, POPs).

AB  - Background: Terrestrial radiation emitted from naturally occurring radionuclides, such as 40K and radionuclides from the 238U
and 232Th series and their decay products represent the main external source of irradiation to the human body. The purpose
of this study was to provide a preliminary assessment of the doses from terrestrial exposure of population in Serbia and to
estimate a potential radiation hazard for population inhabiting investigated areas.
Methods: The gamma dose rates, external hazard indexes, and annual effective doses due to terrestrial naturally occurring radionuclides
(
238U, 232Th and 40K) were calculated based on their activities in soil samples in Serbia as determined by gamma-ray spectrometry.
Results: The total absorbed gamma dose rate due to these radionuclides varied from 16.9 to 125 nGy h-1, with a mean of 62.8
nGy h-1. Assuming a 20% occupancy factor, the corresponding annual effective dose varied from 2.07 to 15.4×10-5 Sv with
the mean value of 7.7×10-5 Sv, i.e. annual effective dose was in range of the world wide average values.
Conclusion: According to the values of external hazard index obtained in this study (mean Hex = 0.35), the radiation hazard
was insignificant for the population living in investigated areas.

The gamma dose rates ranged from 7.40 to 29.7 nGy h(-1) for Ra-226, from 12.9 to 46.5 nGy h(-1) for Th-232 and from 12.5 to 37.1 nGy h(-1) for K-40. The total absorbed gamma dose rate due to these radionuclides varied from 34.5 to 97.6 nGy h(-1) with mean of 66.8 nGy h(-1). Assuming a 20% occupancy factor, the corresponding annual effective dose varied from 4.23 x 10(-5) to 11.9 x 10(-5) Sv with mean of 8.19 x 10(-5) Sv, i.e. the dose was lower than world wide average value. According to the values of external hazard index (mean: 0.39) obtained in this study, the radiation hazard was found to be insignificant for population living in the investigated area.

AB  - The specific activities of primordial radionuclides in soil samples from 21 different locations in Serbia and Montenegro were determined by gamma-ray spectrometry. The results obtained were compared with those from other studies conducted worldwide. Concentrations of radionuclides in soils analyzed in this study ranged from 1.28 to 4.80 ppm for uranium, from 5.26 to 19.0 ppm for thorium, and from 0.97% to 2.87% for potassium. The mean concentrations of U (2.76 ppm) and Th (10.4 ppm) are similar to the world average (2.64 and 11.1 ppm for U and Th, respectively), whereas the mean concentration of K (1.98%) is about 1.4 times higher than world average value (1.37%).
