Analysis of trace elements in the BHQ ice core, Law Dome, Antarctica / Yun-gang Liu, Yun-hui Zhang, Gui-qun Li, Lun Xiao, Zi-chu Xie.
Title: | Analysis of trace elements in the BHQ ice core, Law Dome, Antarctica / Yun-gang Liu, Yun-hui Zhang, Gui-qun Li, Lun Xiao, Zi-chu Xie. |
Author(s): | Liu, Yun-gang. Zhang, Yun-hui. Li, Gui-qun. Xiao, Lun. Xie, Zi-chu. Liu, Yun-kang. Chang, Yun-hui. Li, Kui-ch'ün. Hsiao, Lun. Hsieh, Tzu-ch'u. |
Date: | 1988. |
In: | Journal of Glaciology. (1988.), Vol. 34(118) (1988) |
Abstract: | Analysis carried out using instrumental neutron-activation analysis technique. Jupiter multi-channel analyzer-computer system coupled to Ge(Li) detector was used for acquisition of γ-spectra and for data reduction. "Blanks" in water and in nitric acid, which were used in pre-concentration and sample transfer, were also analyzed. To check validity of analytical procedure, US Environment Protection Agency water standard for trace elements was analyzed. Certified and observed values agreed. Results (in ppb) for eight elements were: Na 209, Mn 0.42, Mg 26, Fe 14, Sc 0.0017, Co 0.028, Al 9.6, Se 0.02. Enrichment factors for these elements relative to Earth's crust were calculated. Elements can be subdivided into three groups according to their enrichment factors. Variations of elemental concentrations with depth show no positive tendency towards systematic increase or decrease over past 5 ka. |
