The summary of the measurements of CO2 stable isotopic composition emitted from different anthropogenic sources in the Kraków region is presented. The sources are divided into three main groups – high emission (electric and heat power plants), low emission (coal and methane burning in the households) and car traffic (gasoline, diesel and LPG supplied engines equipped and not equipped with catalyst). Presented results include two measurement campaigns made in the years 1995 and 2000. The measurements revealed three well-defined groups with respect to carbon isotope composition (delta13CVPDB): –30.60±0.37‰ (car traffic) –23.82±0.10‰ (coal burning) and –51.8±1.1‰ (methane burning). The oxygen isotope composition (delta18OVPDB-CO2) of CO2 varied in a broad range, from ca. –11‰ to ca. –22‰, the most negative values being observed for coal and methane burning and the most positive for cars equipped with
a catalyst. No significant isotopic shift has been observed between two measurement campaigns.
