    Regional Characteristics of Sulfur and Lead Isotope Ratios

    Sulfur and lead isotope ratios in the atmosphere were measured at several selected sites (Harbin, Changchun, Dalian, Waliguan, Shanghai, Nanjing, Guiyang) in China and Tsukuba (Japan), to reveal regional sources characteristics over Eastern Asia. Average S isotope ratios for SO2 and sulfate in the atmosphere in China were close to those of the coals used in each region, indicating a

    Correlations between lead and sulfur isotope ratios in precipitation samples collected in Imizu, Toyama Prefecture. This notion supports the results of Hong's report. According to actual measurement of the isotopic ratios of the Pb and S in the air sampled in China and Japan, the S isotopic ratio was 4.2–6.4‰ in northern China and − 2–0

    Historical lead pollution in the central region of Guizhou

    Lead isotopes in the lake sediments record the history of regional atmospheric Pb pollution. Before the economic reform in 1978, the 208 Pb/ 206 Pb and 206 Pb/ 207 Pb ratios in the leachates of lake sediments were constant, with a range of 2.0060 to 2.0117 and of 1.2314 to 1.2355, respectively.

    Isotope geochemistry

    Isotope geochemistry is an aspect of geology based upon the study of natural variations in the relative abundances of isotopes of various elements. Variations in isotopic abundance are measured by isotope ratio mass spectrometry, and can reveal information about the ages and origins of rock, air or water bodies, or processes of mixing between them.
