Fuji; and (4) needle leaves from pine trees growing in the Higashiyama Campus of Nagoya University. The plant samples were rinsed with distilled water, treated chemically by an acid- alkali-acid treatment, and finally dried in an electric oven. A part of the samples were combusted to produce CO_2 and the produced CO_2 was changed to graphite for ^<14>C measurements with an AMS ^<14>C system at Nagoya University. The measured ^<14>C concentration was given in a ratio of sample ^<14>C/^<12>C to that of standard. For both sample and standard, isotopic fractionation was corrected. In addition, the decrease of ^<14>C concentration by radioactive decay for a standard from AD1950 to the year of sample collection was also corrected. ^<14>C concentrations were highest for the plant samples from Lake Pumayum showing a value of 1.081±0.016 in average, followed by the values of 1.055±0.005 for plants near Lhasa city, the values of 1.051±0,002 for plants from Mt. Fuji, and finally 1.017±0.003 for pine needles from Nagoya University. This clear altitude dependence may be explained preferably by Suess effect that is a dilution effect of modern ^<14>C concentration with dead carbon, containing no ^<14>C, produced by combustion of fossil fuel. The estimated altitude dependence of ^<14>C atom production is not strong and the resulting altitude dependence of ^<14>C concentration of CO_2 can fade out quickly by the strong air-mass mixing in the troposphere.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"第20回名古屋大学年代測定総合研究センターシンポジウム平成19(2007)年度報告<第2部>
