The aim of the proposed bilateral project is to start a long term co-operation between two departments having similar scientific interests and results in the field of analysis and risk assessment of environmental heavy metal contamination, however, using different research approaches. Combining the techniques, which are, even separately, at the frontline of scientific applications, an integrated, highly precise and generally applicable method will be developed, validated and tested. Three approaches will be integrated including high scale hyperspectral air-borne imaginary of high resolution, X-ray fluorescent spectrometry for non-destructive in situ measurement with many sampling points to work out adequate and most reliable sampling strategy, and high tech laboratory techniques for geochemical analyses. After analyzing previous data on the sampling areas both in Croatia and Hungary, the field in situ measurement and the geostatistical analyses will be carried out at both sites with the coordination of the Hungarian party, while laboratory analyses of selected samples with extreme values will be coordinated by the Croatian party and will be carried out in Croatia. The data processing and integration also includes geo-chemical modelling, and validation of hyperspectral data. Based on the data gain for working out a generally applicable method, the sampling sites – Kupa River drainage basin, Glina, Glinica, Radonja, Croatia; and the Valley of Toka stream near Gyöngyösoroszi, Mátra Mountain, North Hungary – will be assessed for environmental risk, providing further information for decision making in risk management.
