An assessment of air quality of Belgrade, Serbia, was performed by determining the trace element content in airborne daily PM 10 and PM 2.5 samples collected from a central urban area. The ambient concentrations of Zn were the highest in PM 2.5 (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.

A detailed study may be undertaken with suitable extractive reagents to define a bio-available fraction of depleted uranium in soil. The comparison of results for different soil types investigated by the same methodology may be useful. An applied combination of physical/chemical procedures and analysis may help in the decision making on the remediation strategy for sites contaminated with depleted uranium used in military operations.
