英文摘要: Pb concentrations and Pb isotopic compositions (total and acid-extractable) in the core sediments collected from Western Xiamen Bay, China, were determined to investigate the Pb pollution history and trace the Pb sources. Pb concentration showed an increasing trend (from 40.3 to 64.2 mg kg− 1) with obvious fluctuation from 1967 to 2013, reflected by the core sediments. The enrichment factors of Pb were between 2 and 5, indicating a moderate enrichment. The relative contributions of Pb-Zn deposit and parent material to total Pb in the core sediments were 51%–62% and 38%–49%, respectively. Acid-extractable Pb isotopic signature was more sensitive than total Pb isotopic signature in identifying anthropogenic Pb sources due to the substantial variability of acid-extractable Pb isotopic ratios exhibited in the core sediments. Based on the acid-extractable Pb isotopic ratios, Pb-Zn deposit and industrial emission were regarded as the main anthropogenic Pb contributors. © 2016 Elsevier Ltd Citation statistics:
