Tartalmi leírás:
Dust and metal deposition are of important significance as an indicator of local air quality.
However, their vertical deposition characteristics at greater heights are not well known. Settling dust
samples were collected at four heights and at both sides of a 40 meters high building next to a busy urban
road in Budapest, Hungary. In this study, concentrations and monthly deposition rates of nine elements
are (Ba, Ca, Cr, Cu, Fe, Mn, Pb, Sr, Zn) evaluated. The study site can be characterized by average settling
dust load showing a slight seasonal variation. Highest contamination was found for Cu, Pb and Zn. The
sources of these metals could be the traffic and the weathering of materials of the built environment. The
enrichment of these metals is generally the highest at the road-side of the building and at lower sampling
heights, but Pb and Zn may show strong enrichment even at 33 m and at the low-traffic side of the
building. This is generally the highest in the dry and windy periods suggesting the dominance of the resuspension
of urban soil and road dust in the metal deposition. The vertical dust and metal deposition
patterns mostly correspond to the supposed air-flow model but just in case of highest chance of resuspension
a special model is needed to clearly describe the deposition patterns. This is probably due to
the simultaneous effect of weather conditions and the morphology of natural and built environment.
