Radiocarbon in tree rings from a clean air region in Slovakia.
TL;DR: Comparison with two previously reported modern tree ring data sets from Slovakia showed that radiocarbon levels at both locations are lower than clean air reference values, indicating the influence of local fossil fuel emissions.

TL;DR: The Vysoká pri Morave 14C data were during 1974-1995 systematically lower by about 50‰ than the Schauinsland (Germany) clean air reference values due to a regional fossil-fuel impact, however, after 1996 the Vysoko pri Moraves data were closer to the SchAUinsland data due to lower CO2 emissions as a result of closing some of the heavy industry technologies in the region.

Radiocarbon analysis of carbonaceous aerosols in Bratislava, Slovakia.
TL;DR: The results show that on average the fossil fuel combustion is the dominant source of EC aerosol particles in Bratislava and in summer months, they represent more than half (65-80%) of the total EC aerosols.

TL;DR: An international consortium of radiocarbon (14C) laboratories was established to date the origin of the St George's Rotunda in Nitrianska Blatnica (Slovakia), because its age was not well established in previous investigations.
