| 摘 要： | Measurements of Pb in the well-preserved and dated snow and ice layers in glaciers can be used to recon- struct the past changes of atmospheric lead concentra- tions and to determine the trends of atmospheric pollu- tion. The lead data obtained from Greenland ice cap revealed severe air pollution in the Northern Hemi- sphere over the past three millennia. This lead pollution started from as early as Rome times[1], and increased remarkably from the Industrial Revolution to the end of the 1960… |

| Abstract: | A Muztagata ice core recovered at 7010 m altitude in East Pamirs provides a Pb concentration record from 1955 to 2000. The result reveals in- creasing Pb concentrations from 1955 to 1993, with two Pb concentration peaks in 1980 and 1993. After 1993, Pb concentrations in ice core show an obvi- ously declining trend. Analysis shows that the lead in the Muztagata ice core mainly came from anthropo- genic emissions from countries in Central Asia, while the local emission had little contribution. |
