| 内容記述 | Snow and ice samples collected from a snow pit and underlying ice layers in Sofiyskiy Glacier, Russian Altai Mountains, were analyzed for n-alkanes by gas chromatography. The total concentrations of n-alkanes (T-HCs) widely ranged from 0.67 to 9.86ng g^<-1> in the samples. Annual deposition fluxes of n-alkanes showed a seasonal variation with higher levels during spring than autumn. The values of carbon preference index (CPI) of n-alkanes ranged from 0.95 to 3.35, which were similar to those reported for snow samples in Himalaya and urban aerosols. The higher values among them were close to those reported of n-alkanes in loess particles, which were of plant wax origin. Both the 3.00-7.57m and the 12.14-16.80m layers had higher concentrations and annual deposition fluxes of non-WaxC_n, suggesting that the relative contribution of anthropogenic n-alkanes, for example, fossilfuel combustion products, to Sofiyskiy Glacier would increase in recent years. The WaxC_n representing a portion of n-alkanes derived from plant waxes in T-HCs widely ranged from 7.3 to 65.5% in these samples. It is evident that n-alkanes of plant waxes could contribute less than 50% to T-HCs in most samples at this glacier. | |||||
