Within the Properties and Behaviour of Atmospheric Microconstituents Project research ongoing

ozone monitoring (since 1988) at station Puntijarka was continued and similar monitoring at

stations Srđ and Mali Lošinj were terminated. The measurements at Srđ and Mali Lošinj are

considered finished and the results of data analyses were published. The data are stored at RBI

and when needed used in other investigations or cooperations in European atmospheric projects

within the ACCENT - Network of Excellence as its member since 2005 (after the finish of

EUROTRAC). Various methods for analysis of atmospheric microconstituents, computer and

statistic methods for data handling, measurement interpretations in connection to meteorological

parameters and data, altitude and long-range transport were examined and tested. Frequency

analysis by Fourier transformation (FT) of long term ozone data from 12 European

EUROTRAC/TOR stations showed therein otherwise difficult to recognize periodicities. In 2005

volatile hydrocarbons in air were measured at Mali Lošinj and Kopački Rit within a bilateral project

with Faculty for chemistry and chemical technology, University of Ljubljana. With them, an Italian

and a Hungarian partner also a project proposal entitled «Ozone induced forest injury and forest

preservation in Hungary, Croatia and Slovenia» for financing within the Community Initiative

INTERREG IIIA, Neighbourhood Programme Slovenia-Hungary-Croatia 2004-2006 project was

submitted. Some measurement results particularly their effect on mortality increase in Croatia and

forest damage on mountain Medvednica were analyzed and published. Scientific achievements

were published in peer reviewed scientific journals covered by Current Contents, some also in

Proceedings of scientific meetings
