Historical rates of atmospheric Pb deposition using210Pb dated peat cores: Corroboration, computation, and interpretation

Accumulation rates and predominant atmospheric sources of natural and anthropogenic Hg and Pb on the Faroe Islands

“…Even at the predominately minerotrophic peatland of Tourbière des Genevez in the Swiss Jura, both Pb (Shotyk, 2002) and Hg (Roos-Barraclough and The data presented here also argue that Pb and Hg are well retained in the peat profile. There is a growing body of information suggesting that Pb is immobile in ombrotrophic peat (Vile et al, 1995;Shotyk et al, 1996;Bränvall et al, 1997;Farmer et al, 1997;Kempter et al, 1997;MacKenzie et al, 1997;Martinez-Cortizas et al, 1997;Norton et al, 1997;Shotyk et al, 1997;MacKenzie et al, 1998;Shotyk et al, 1998;Kempter and Frenzel, 1999;Vile et al, 1999;Weiss et al, 1999a;Weiss et al, 1999b;Kempter and Frenzel, 2000;Vile et al, 2000;Shotyk et al, 2001;Martinez-Cortizas et al, 2002;Nieminen et al, 2002;Renberg et al, 2002;Shotyk, 2002;Shotyk et al, 2002b;Weiss et al, 2002;Givelet et al, 2003;Klaminder et al, 2003;Novak et al, 2003;Givelet et al, 2004;Le Roux et al, 2004). Taking Pb to represent an immobile reference element, the coincidence of the Hg (Fig.…”

The impact of mining activities on the environment reflected by pollen, charcoal and geochemical analyses

“…In ombrotrophic peat bogs lead is effectively immobilized (Vile et al, 1995(Vile et al, , 1999Shotyk et al, 1997;MacKenzie et al, 1997;Weiss et al, 1999a,b), allowing them to be used as archives for the reconstruction of atmospheric Pb deposition (Brä nvall et al, 1997;Cortizas et al, 1997;Farmer et al, 1997;Shotyk et al, 1998Shotyk et al, , 2002. Although bogs are thought to provide better geochemical data, it has recently been shown that fens, too, are suitable to record atmospheric deposition without significant distortion.…”

Measurements and Models for Trace Element Input and Time Distribution Recorded in Forest Soil and Bog Ecosystems

“…Additional aliquots of each layer were taken for ICP-MS and ICP-AES analysis where up to 60 elements can be analyzed simultaneously. The ICP-MS data from the Czech Republic have been re-calculated and values for several metals can now be compared with independent Pb measurements by Vile et al [7] on nearby cores. Duplicate samples were taken, where possible, and quality control procedures used to validate the analytical results.…”

“…Bozi Dar Bog, 50°24' N, 12°54' E, is located in the Krusne hory Mountains of northern Bohemia near the center of the heavy industries of central Europe and has precipitation of 850 mrn/y. The peat deposit reaches 5.5 m depth and consists of Sphagnum-derived material that has had little growth in recent years [7].…”
