| 英文摘要 | Integrated analyses of grain size, Pb-210 stable isotope, and heavy metals were performed to characterize the sedimentary core LDC30 collected from the southeastern Liaodong Bay of China and investigate the 100-year history of heavy metal accumulation. The aluminum-normalized enrichment factors and the excess metal fluxes (MFxs) indicated that the metal accumulation in the southeastern Liaodong Bay occurred in three stages: a pre-industrial stage (prior to 1960s) with natural accumulation, an initial industrial stage (1960-1990) with slowly elevated accumulation, and an industrialized stage (post-1990s) with accelerated accumulation. A moderate enrichment of Cd and Pb (up to 4.1- and 2.6-fold over the baseline, respectively) and a slight enrichment of Cr, Cu, Ni, and Zn (up to 1.3-fold) were measured in the recent sediments. Multivariate analysis demonstrated that the Cr, Cu, Ni, and Zn were from the natural origin, whereas Cd and Pb from the anthropogenic origin. The MFxs of Cd and Pb showed a drastically increasing trend since 1990s, which could result from the intensive application of fertilizers and combustion of fossil fuels. |
