摘要：Austrian Bioindicator Grid - Sulphur Impact in
2006 and First Results of 2007
In Austria, the impact of sulphur has been assessed since
1983 by means of the Austrian Bioindicator Grid. Annual
sampling allows a precise assessment of the temporal and
regional evolution of the impact of sulphur based on legal
standards. Despite the reduction of SO2 emissions in
Austria and in the neighbouring countries, in 2006,
exceedances of the legal standard were still reported on 56
of the 769 plots. Approximately 65 % of the 56 polluted
plots were located in the federal provinces of Burgenland,
Lower Austria and Styria. The analyses of the 2007 samples
have not yet been completed; first results show a slight
decrease of plots with limit exceedances.
