摘要	Methods were developed to determine the mass ratios of carbon isotopes in trace amounts of aerosol carbonate. A Finnigan MAT 252 mass spectrometer fitted with an on-line Kiel device was to determine the C-13/C-12 ratio in CO2 produced from the carbonate. A study using these methods was conducted to characterize the carbonate carbon isotopes in aerosol samples collected in Xi'an on dusty and normal days during March and April 2002. Results of the study demonstrate that insights into the origin of the dust can be deduced from its isotopic composition. That is, the delta(13)C of carbonate for dust storm samples ranged from -1.4parts per thousand to -4.2parts per thousand, and this is consistent with sandy materials in dust source regions upwind. In contrast, for non-dusty days delta(13)C ranged from -7.5% to -9.3parts per thousand, which is more similar to fine particles emitted from local surface soils. Comparisons of dust storm aerosols with surface soils from source regions and with aerosol samples collected downwind indicate that the delta(13)C values did not change appreciably during long-range transport. Therefore, carbon isotopes have the potential for distinguishing among source materials, and this approach provides a powerful new tool for identifying dust provenance.
