Abstract
Pb stable isotope signatures analysis can be used to identify its sources precisely and the spatial transportation process to achieve precise management of target areas. In this study, 12 surface (0-10 cm) soil samples (3-5 replications for each site) were collected on the Yancheng coast. Pb isotopes (206Pb, 207Pb and 208Pb) and Pb contents were analyzed by inductively coupled plasma mass spectrometry. Results showed that the soil Pb contents were as high as 1.7 times of the background Pb content value. Referencing the national criteria of GB 15618-2008, the study area was polluted by Pb to a relatively serious extent. The analysis indicated that main Pb sources of the area were local, including Sheyang Power Plant, Shuangdeng Paper Mill Sewage Plant, and Huafeng industrial area near Wanggang. Based on the normalized difference vegetation index (NDVI) and distance analysis, we figured out the key patterns of Yancheng coast to cope with the press sources.
