Isotopic identification of natural vs. anthropogenic lead sources in marine sediments from the inner Ría de Vigo (NW Spain)

Bromine enrichment in marsh sediments as a marker of environmental changes driven by Grand Solar Minima and anthropogenic activity (Caminha, NW of Portugal)

“…However, the influence of leaded gasoline increased from almost negligible in AD 1930 to 13-24% by AD 1975 . Similar values are reported from an estuarine system in NW of Spain (Alvarez-Iglesias et al, 2012) closer to our study site. On the other hand, a peat bog from NW Spain (Martinez-Cortizas et al, 2012) and other European records (Shotyk et al, 1998;Dunlap et al, 1999) suggest greater contributions from leaded gasoline.…”

“…On the other hand, a peat bog from NW Spain (Martinez-Cortizas et al, 2012) and other European records (Shotyk et al, 1998;Dunlap et al, 1999) suggest greater contributions from leaded gasoline. Regionally, the Pb concentration peak has been reported to be at 1955-1962(Olid et al, 2010Alvarez-Iglesias et al, 2012), comparable to Caminha (AD 1960), which might point to a significant input from local sources. The profile of total Pb from Caminha increases from AD 1930 towards 1960s and 1970s and then decreases, following a similar pattern than those found elsewhere (see references above).…”

A New Analytic Model to Identify Lead Pollution Sources in Soil Based on Lead Fingerprint

“…Eades [16], Bird [17][18][19], Ferrand [20], and Miller [21] studied lead pollution sources in the aquatic environment. Chiaradia [22,23], Camarero [24], Álvarez-Iglesias [25], and Luo [26] presented detailed analyses about the lead sources in soil and sediments with the Gobeil's model. Kylander [27], Lima [28], and Anderson [29] carried out some similar research using the Gobeil's model in the field of geology and mineral resources.…”

Elemental Profile and 207Pb/206Pb, 208Pb/206Pb, 204Pb/206Pb, 87Sr/86Sr Isotope Ratio as Fingerprints for Geographical Traceability of Romanian Wines

“…The Pb isotope ratio can be used to identify the sources and transport pathways of Pb in pollution studies (Hu et al, 2015). Previous works have shows that the use of lead isotopes is a good tool in order to know the origin of Pb and to identify the types of Pb according to anthropogenic or geogenic origin (Ettler et al, 2004;Li et al, 2011;Álvarez-Iglesias et al, 2012); this is because the Pb emitted into the atmosphere maintains a characteristic isotopic composition (signature) and does not change during the physical/ physicochemical processes associated with smelting, refining or manufacturing (Flegal and Smith, 1995 Pb from wines and soil of origin (Avram et al, 2014;Kristensen et al, 2016;Dehelean and Voica, 2012;Almeida et al, 2016), this representing the starting premise for geographical origin determination. The lead isotope ratio depends on factors such as thorium and uranium content in the soil, weathering processes and original rock age, which provide a fingerprint used for different forensic and archeological purposes (Komárek et al, 2008;Roux et al, 2004;Dreyfus et al, 2007).…”
