Description: From June to mid-October in 1995, the concentration of tropospheric ozone in 18 localities in the Krakow Province of southern Poland was measured by using ultraviolet monitors and Ogawa passive samplers. At three active monitoring stations, tropospheric ozone was recorded in the downtown and western part of Krakow and in Szarow, 30 km to the east. The passive method was applied in a dozen or so localities distributed within and outside Krakow's city limits. In these locations two varieties of tobacco (Nicotiana tabacum L.), Bel-W3 and Bel-B, were exposed. In the Krakow Province the mean 24-hour ozone concentration (from active monitors) was higher than 30 μg/m³ (24-hour Polish standard) in June through July and part of September. The highest concentration was recorded in early afternoons and the lowest between midnight and sunrise. The maximum 30-minute concentration of 205 μg/m³ occurred in August. However, great diversity of the tropospheric ozone concentration (measured with passive samplers) was recorded in all locations. The lowest average concentration was recorded in Krakow and areas located west, northwest and east of the city, whereas the highest average concentration was recorded in the north, northeastern, southeastern, and southwestern parts of the Province. The highest average concentration of 100 μg/m³ for a 2-week period of filter exposure was recorded in July and August from the sites Ratanica, located 40 km south, and Goszcza, 25 km north of Krakow. The amount of damage to the leaves of the ozone-sensitive variety of tobacco (Bel-W3) exposed at all sites was correlated (coefficient 0.69, p<0.000) with concentration results obtained with passive samplers. Greater damage was recorded in the sites located outside the city than elsewhere, whereas the damage that occurred within Krakow was markedly smaller.
