Sažetak
The series of 1226 samples of 24-hours SO2 concentration data in Veli Lošinj during the period 1986-1989 have been analysed together with basic meteorological variables measured on Mali Lošinj at 3 climatological terms. The day-to-day synoptic weather types are examined in order to relate synoptic scale flow patterns to the SO2 concentration data. The pollution level in Lošinj area was found to be considerably lower than the minimum legal value of SO2 based on public health criteria which is 60 μgm-3 for 24 hours. Nevertheless,
particular meteorological conditions such as anticyclonic situations with slight winds from SW-NW direction in winter and bora favourable conditions in spring produced the limited number of situations with 24-hour SO2 concentration level greater than 40 μgm-3. From the analysis of the effects of various meteorological elements wind speed and directions were found to be best correlated with the pollution concentration. It is shown that the worst cased air pollulion situations in areas of low emission rates are not necessarily stagnation periods but my be periods with good ventilation.
