In Austria, the impact of sulphur has been assessed since 1983 with the help of the Austrian Bioindicator Grid. The annual sampling allows a precies evaluation of the temporal and regional development of the impact of sulphur on the basis of legal standards. Despite the reduction of SO2 emissions in Austria, the legal standard has still been exceeded on 5-10 % of the plots in the last years. These plots are mainly located near large Austrian emittors, but also in areas affected by transboundary sulphur emissions from neighbouring countries. The present paper describes one example how the Bioindicator Grid can be applied for the control of legal requirements to enact effective clean air measures in Austria and take supportive measures that reduce the impact of sulphur from emittors in neighbouring countries.
