英文摘要: In order to identify the sources of organic carbon (OC) and elemental carbon (EC) in airborne PM2.5 in Hangzhou, OC and EC were oxidized to CO2 offline in two thermal steps, and their carbon isotope compositions were measured by mass spectrometer. Results showed that the average delta C-13(OC) values were -52.8 parts per thousand, -48.1 parts per thousand, -50.0 parts per thousand and -52.5 parts per thousand in spring, summer, autumn, and winter, respectively, and the annual average value was -50.9 parts per thousand, (-85.0 parts per thousand to -35.6 parts per thousand), whereas delta(13)C(EC)values were -26.4 parts per thousand, -26.9 parts per thousand,, -26.7 parts per thousand and -25.9 parts per thousand in the four seasons, and its annual value was -26.5 parts per thousand (-30.5 parts per thousand,, to -23.8 parts per thousand,,). Large differences were found between isotope compositions of the two types of carbon. delta C-13(OC) values were much smaller than those of delta C-13(EC), and varied in a large range, and the ratios in both spring and winter were the smallest. delta C-13(EC) varied in a small range, and its mean values in four seasons were nearly the same. This suggests that the carbon isotope compositions of OC and EC in PM2.5 can provide useful information in distinguishing their sources.
