Regional variations in the lead isotopic composition of galena from southern Korea with implications for the discrimination of lead provenance

Source identification of heavy metal contamination using metal association and Pb isotopes in Ulsan Bay sediments, East Sea, Korea

“…6), which indicated that the background Pb in sediments originated from the natural weathering of surrounding crystalline and sedimentary rocks, which had similar isotopic characteristics (Jeong et al, 2012) and transported into sediments in the bay through the Taehwa River. The isotope ratios of Pb in background sediments were similar to those (0.843 ± 0.001 and 2.093 ± 0.003 in shelf and slope sediments, respectively) reported for sediments deposited in the previous 100-150 years in the Ulleung Basin (Choi et al, 2006(Choi et al, , 2007b, non-polluted sediments (0.842 and 2.091, respectively) deposited at 15-30 cm in the East China Sea (Wang et al, 2014), and those (0.8419 ± 0.0005 and 2.0896 ± 0.0014, respectively, n = 46) in sediments deposited 500-15,000 years ago in the Yellow Sea (Choi et al, 2007a), but slightly higher than bulk Chinese loesses (0.834 and 2.076, respectively; Wu et al, 2011) and non-polluted bulk sediments (0.837 and 2.077, respectively) in the Yangtze River estuary (Hao et al, 2008).…”

“…The isotopic composition of Pb ores imported from each country might have distinct characteristics that allow them to be differentiated from each other. Fortunately, Pb isotopes from Australia, the United States, Peru, South Africa, China, and Canada can be significantly differentiated (Bollhöfer and Rosman, 2000), and their Pb isotope ratios were plotted to estimate the anthropogenic Pb sources in surface and core sediments by dividing them into three groups of mixing lines, together with the imported ores and the seven local ores near Ulsan Bay (Jeong et al, 2012) (Fig. 7).…”

“…7. Comparison of isotope ratios of estimated anthropogenic Pb sources with sources-related materials such as ores from Australia, Peru & Mexico and USA(Bollhöfer and Rosman, 2000), local ores(Jeong et al, 2012), vehicle exhausts from cars using leaded gasoline in China(Chen et al, 2005) and leaded gasoline in Korea(Choi et al, 2007b).…”

Lead chromate detected as a source of atmospheric Pb and Cr (VI) pollution

“…1)26 as well as domestic coal (1.2202 ± 0.0035 from Taeback in Fig. 1)26 and Pb ores (1.1822 ± 0.0411)27 in Korea. Likewise, the values were significantly higher than the calculated 206 Pb/ 207 Pb of Pb ores imported to Korean lead smelters (1.1343)26.…”
