| 英文摘要 | Palaeovariations of the atmospheric Pb-210 flux in Northeast China (Long Gang area, Jilin province), quantified by high resolution Pb-210 measurements on seasonally laminated sediments of Lake Sihailongwan are presented on decadal scale. The mean flux of unsupported Pb-210 between 1790 and 1970 for the centre of the lake basin is 517 Bq m(-2) yr(-1) with maximum deviations between -23% and +27% of this value. Flux rates above this average were found between 1783 and 1813, around 1836, and between 1860 and 1901. The mean Pb-210(exc) flux rates derived were clearly lower around 1821, 1908, 1930, and 1953. The Pb-210(exc) flux reached its minimum of 344 Bq m(-2) yr(-1) during the period 1977-1982. The atmospheric flux of unsupported Pb-210 is correlated with the precipitation frequency during the summer monsoon and shows coinciding variability with geochemical proxies that document the groundwater inflow into the lake. Al2O3-rich dust of remote provenance scavenged by wet-deposition in the rainy season is the major carrier of the atmospheric Pb-210(exc) flux. |
