| Zusammenfassung |
| Data provided by the UNEP’s report on mercury [1] shows that solid fuel combustion in
significant source ofÂmercury emission to air.
Silesia, located in southwestern Poland, is notably affected by mercury emission due to
being one of the most industrialized Polish regions: the place of coal mining, production of
metals, stone mining, mineral quarrying and chemical industry. Moreover, Silesia is the
region with high population density. People are exposed to severe risk of mercury emitted
from both: industrial and domestic sources (i.e. small household furnaces). Small sources
have significant contribution to total emission ofÂmercury.
Official and statistical analysis, including prepared for international purposes [2] did not
provide data about spatial distribution of the mercury emitted to air, however number
ofÂanalysis on Polish public power and energy sector had been prepared so far [3; 4]. The
distribution of locations exposed for mercury emission from small domestic sources is
interesting matter merging information from various sources: statistical, economical and
environmental.
This paper presents geostatistical approach to distibution ofÂmercury emission from coal
combustion. Analysed data organized in 2 independent levels: individual, bottom-up
approach derived from national emission reporting system [5; 6] and top down – regional data
calculated basing onÂofficial statistics [7].
Analysis, that will be presented, will include comparison of spatial distributions of
mercury emission using data derived from sources mentioned above. Investigation will
include three voivodeships of Poland: Lower Silesian, Opole (voivodeship) and
Silesian using selected geostatistical methodologies including ordinary kriging
[8].
