| Zusammenfassung |
| Benzo(a)pyrene (BaP) - a marker for the carcinogenic risk of polycyclic aromatic
hydrocarbons (PAHs), is formed during inefficient combustion. Transportation and domestic
combustion of solid fuels, including biomass, are known to be its major emission sources.
The European Council has established in Document 2004/107/EC that the ambient
concentration of BaP, starting from 31.12.2012, should not exceed 1 ng m-3 for the total
content in the PM10 fraction averaged over a calendar year.
In Austria, the concentration threshold of BaP has been until now often violated, due to
high share of biomass burning emissions in atmospheric pollution burden (e.g., report by
Bauer et al., 2008).
The following experiment is part of a study characterizing wood burning particles from
domestic sources in Austria and describes the BaP emissions.
We present the emission rates of PM10 and particulate PAHs from burning of the major
wood species grown in eight Mid-European countries. The logwood tests were performed
with modern small-scale ( |
