摘要：

The isotopic composition of atmospheric CO2 and its concentration in the Krakow region has been measured since 1983. Air samples have been collected in bi-weekly intervals close to the center of Krakow. The six years records (1983-1988) of these data reveal multi-annual linear trends and winter-summer oscillations. The calculated parameters of the individual regression lines (intercept and slope) for the measured DELTA-C-14, delta-C-13 and CO2 concentration, C, are: 173 parts per thousand (January 1983) and - 10.7 parts per thousand yr-1, -9.58 parts per thousand (January 1983) and -0.038 parts per thousand yr-1, 371 ppmv (January 1983) and 1.0 ppmv yr-1, respectively. The C-14 activity in tree leaves collected in a mountain region, about 60 km from Krakow was also assessed. The parameters of the linear decrease of C-14 activity in tree leaves are: 239 parts per thousand (January 1983) and 21 parts per thousand yr-1.
