Sažetak
The continous ozone monitoring in the Rijeka bay started only in 1999 in the city center (Institute buiding) and was extended to five more sampling sites in 2003. The first evaluation of ozone at four selected sampling sites is given: urban Site 1, resort Site 2, industrial („ fence line“ ) Site 3 and suburban Site 4 (above the eastern industrial zone). The lowest ozone level was found at Site 1, while the highest was obtained at the suburban Site 4, as expected. All sites exhibit decline in ozone concentrations, the most pronaunced at suburban Site 4, while almost constant at resort site 2. The concentration roses for Site 3 and 4 agree with the prevailing wind directions, pointing to the coastal line, where the major pollution sources are located. In spite of dominant wind ditection from N-NW sector, the dominant sector in concentration rose is SW at Site 1, while there is no distinct direction in the concentration rose at resort Site 2. Due to different meteorological conditions, the AOT40 values differ considerably, e.g. several thousands in 2007 or up to 45.000 μ g*h/m3 in 2005.
