Abstract
|
|
|
|
We have collected a batch of leaf samples at several main crossroads in Daejeon and a background site to obtain distribution of CO₂(greenhouse gas) due to fossil fuel combustion. The leaf samples were treated with AAA method and Δ14C values of them were measured using AMS. Δ14C values of downtown sites were found to be lower by 27-102 ‰ than that of the background site, and the ratio of CO₂originated from fossil fuel combustion in the atmosphere of Daejeon could be calculated from the differences of Δ14C values. The average Δ14C of the background site, around Kyeryong mountain, was measured to be 35±8 ‰, and this value is lower than 66.3‰, which have been known as the backgdound values in USA.
