东帕米尔高原海拔7010 m的慕士塔格冰芯记录了1955 ~ 2000年的Pb浓度。结果表明，从1955年到1993年，铅的浓度增加，在1980年和1993年的两个铅浓度峰值。1993年以后，冰芯中Pb含量呈明显下降趋势。分析表明，慕士塔格塔冰芯中的铅主要来源于中亚各国的人为排放，而本地排放的贡献很小。
A Muztagata ice core recovered at 7010 m altitude in East Pamirs provides a Pb concentration record from 1955 to 2000. The result reveals increasing Pb concentrations from 1955 to 1993, with two Pb concentration peaks in 1980 and 1993. After 1993, Pb concentrations in ice core show an obviously declining trend. Analysis shows that the lead in the Muztagata ice core mainly came from anthropogenic emissions from countries in Central Asia, while the local emission had little contribution.
