Applications of lead isotope ratio measurements

Fingerprinting Marcellus Shale waste products from Pb isotope and trace metal perspectives

“…Pb isotopes are useful in environmental contaminant tracer studies, because the daughter Pb isotopes 206, 207 and 208 are produced from parents (respectively 238 U, 235 U, 232 Th) at different decay rates that could reflect differences in age of Pb sources or sequestration processes (Faure, 1998;Snyder et al, 2004). Because Pb isotopes are not measurably fractionated during industrial or biological processes (Ault et al, 1970), they can be an important tracer for identifying contamination to and through ecosystems (e.g., Graney et al, 1995;Krachler, 2007;Komarek et al, 2008;Yip et al, 2008;Graney and Landis, 2013). High concentrations of trace metals in black shales, combined with the possibility for altered Pb isotope values from U decay, could be useful in distinguishing Marcellus Shale waste products from other formations.…”

Characteristics of heavy metals and Pb isotopic signatures in sediment cores collected from typical urban shallow lakes in Nanjing, China

“…Recently, several studies have been conducted to assess contamination and fractionation of heavy metals in sediments, suspended particulate matter, and snowmelt and rainfall/runoff (Estebe et al, 1998;Monna et al, 1999;Li et al, 2000;Lindstrom and Hakanson, 2001;Liu et al, 2008); however, few investigations have been conducted to evaluate the sediment cores in typical urban shallow lakes in developing countries to assess heavy metal contamination. Lead from different sources is characterized by different isotopic ratios and physico-chemical fractionation processes do not significantly alter the Pb isotopic composition of Pb sources, the use of the lead isotope ratio is sometimes referred to as "lead fingerprinting" (Ault et al, 1970;Aggarwal et al, 2008;Komárek et al, 2008;Yip et al, 2008). Since the 1970s, Pb isotopes have been used to trace environmental pollution with heavy metals and to survey anthropogenic emission, fallout and impact of the heavy metals in the environment (Aggarwal et al, 2008;Komárek et al, 2008;Reimann et al, 2008;Yip et al, 2008).…”

Research has been carried out on Pb isotopic signatures in water and sediments in order to trace or identify the anthropogenic lead sources (Renberg et al, 2002;Choi et al, 2007;Bentahila et al, 2008;Komárek et al, 2008;Soto-Jimenez et al, 2008;Zhang et al, 2008;Townsend et al, 2009).…”
