Artificial and natural radionuclides in spruce needles in Upper Austria from 1983 to 2008 - an application for radioecological monitoring
The spatial and temporal distribution of activity concentrations in spruce needles were comprehensively analysed and illustrated. Further on, the relation between natural and artificial radionuclides in spruce needles was determined. To estimate the long-term behaviour of 137Cs, ecological half-lives were calculated for the compartment spruce needles.  >>>
Assessment of Mercury in Needles of Forest Trees
In the Austrian forest law “Zweite Verordnung gegen Forstschädliche Luftverunreinigungen, BGBl. Nr. 199/1984”, there are threshold values specified for the concentrations of several pollutants in leaves and needles. However, there are no such threshold values specified for mercury. From the current results of the Austrian Bio-Indicator Grid a threshold value of 0.017 mg Hg/kg can be derived, above which mercury pollution must be assumed.  >>>
Impact of Environmental Change on the Radioecology of Spruce Trees in Upper Austria
In a two years project spruce needle samples of the Austrian Bioindicator Grid were analysed by gamma spectrometry to detect the geographical and temporal distribution of radionuclides with the main focus on the radioactive contamination before and after the Chernobyl fallout in 1986. This Poster was presented on the 12th International Congress of the International Radiation Protection Association/Buenos Aires 19 / 24 October 2008.

Austrian Bio-Indicator Grid (Poster)
The aim of this monitoring programme is to identify air pollutants and nutrient imbalances through foliage analysis and to show their temporal and spatial variation. In addition to national efforts to identify transboundary pollution sources, these data are used in forest-technical appraisals by the local forest authorities in legal proceedings according to the mining, waste and trade law to prove the impact of air pollutants.

137Cs and 90Sr contamination of spruce needles in the northern region of Austria
137Cs and 90Sr concentrations in spruce needles have been determined in samples gathered from Norway spruce trees at various locations the northern part of Austria.  >>>
International Conference on Ecological Remediation and using of Bioindication Methods (25.-26.8.2005 Velenje/SLO)
The aim of the conference was to put attention on qualitative and quantitative aspects of biomonitoring and bioindication methods before and after ecological remediation, on innovative use of bioindicators in risk assesment and on the processes avalaible for improving environmental condition.
