| 英文摘要 | High-altitude lake sediments can be used as natural archives to reconstruct the history of pollutants. In this work, the temporal distribution of polycyclic aromatic hydrocarbons (PAHs) was determined in a sediment core collected from the southern Tibetan Plateau (TP), which was dated by using the Pb-210 dating method and validated with the Cs-137 fallout peak. The concentrations of the anthropogenic PAHs (Sigma(8)PAH) in the sediment core ranged from 0.83 to 12 ng/g dw, and the fluxes of the Sigma(8)PAH were in the range of 2.1-27 g/cm(2)/year. The temporal variations in the concentration and input flux of anthropogenic PAHs were low with little variability before the 1950s, and then gradually increased from the 1950s to the 1980s, and an accelerated increase was observed after the early 1980s. The content of total organic carbon played an insignificant role in affecting the time trends of PAHs in the sediment core. Diagnostic concentration fractions of PAH components indicate PAHs in the lake sediment of the southern TP which are mainly from biomass burning and/or from long-range atmospheric transport. |
