Assessment Of Air Quality And Atmospheric
Deposition In Hungary
Author(s)

Abstract
Annual average atmospheric concentrations and depositions of sulfur and
nitrogen species, as well as trace metals in Hungary and its surrounding regions
were estimated by model computations. Spatial and temporal variations of the
distributions are presented in this paper. The temporal variation of atmospheric
sulfur budget was calculated based on a simple atmospheric box model. In the
case of atmospheric lead, the cumulative atmospheric depositions were also
estimated for a sixty-year long period until 2015 using historical emission factors
for the past decades as well as emission scenarios for the future. It was found
that Hungary belongs to the moderately polluted regions of Europe. It was also
estimated that a significant part of the tropospheric ozone and its precursors are
imported to Hungary through long-range atmospheric transport processes. Based
on dispersion model computations, spatial distribution of PM10 was also
estimated for Budapest to get detailed information on the particle pollution level
at different locations in Budapest.
Keywords: atmospheric deposition, long-range atmospheric transport, regional
and urban air quality.
1 Introduction
For the past decades, energy generation, industrial production and transportation
have caused serious environmental contamination in East-Central Europe. The
rate of contamination can vary from place to place as a function of source
densities and intensities of pollutant fluxes as well as meteorological conditions.
The pattern of pollution may be characterized not only by local, highly
concentrated sites such as densely populated urban areas, but also by lower
