“…A considerable percentage of TMs released to the atmosphere is often carried by long range transport, deposited by precipitation or as aerosols, and stored in and between aquatic and terrestrial ecosystems in remote areas. Long term records to quantify accumulation of TMs in natural geological archives are helpful to differentiate and document the temporal trends of natural versus anthropogenic TMs [4][5][6][7][8]. The magnitude and history of changes in past metal deposition have been studied in a variety of environmental records in the Northern Hemisphere, such as ice core [9], lake sediment [10,11] and ombrotrophic peat [12,13].…”

Atmospheric Deposition History of Trace Metals and Metalloids for the Last 200 Years Recorded by Three Peat Cores in Great Hinggan Mountain, Northeast China

A large number of studies on trace metals and metalloids (TMs) accumulations in peatlands have been reported in Europe and North America. Comparatively little information is available on peat chronological records of atmospheric TMs flux in China. Therefore, the objective of our study was to determine the concentrations and accumulation rates (ARs) of TMs in Motianling peatland from Great Hinggan Mountain, northeast China, and to assess these in relation to establish a historical profile of atmospheric metal emissions from anthropogenic sources. To meet these aims we analyzed 14 TMs (As, Ba, Cd, Co, Cr, Cu, Mo, Ni, Pb, Sr, Sb, Tl, and Zn) and Pb isotopes ( Pb ratio close to 1.9. ARs and enrichment factors (EFs) of TMs suggested enhanced metal concentrations near the surface of the peatland (in peat layers dated from the 1980s) linked to an increasing trend since the 2000s. This pollution pattern is also fingerprinted by the Pb isotopic composition, even after the ban of leaded gasoline use in China. Emissions from coal and leaded gasoline combustions in northern China are regarded as one of the major sources of anthropogenic Pb input in this region; meanwhile, the long-distance transportation of Pb-bearing aerosols from Mongolia should be also taken into consideration. The reconstructed history of TMs' pollution over the past ca. 200 years is in agreement with the industrial development in China and clearly illustrates the influence of human activities on local rural environments. This study shows the utility of taking multi-cores to show the heterogeneity in peat accumulation and applying PCA, EF and Pb isotope methods in multi-proxies analyses for establishing a high resolution geochemical metal record from peatland.

“…Such airborne components arrive at the peatland's surface by wet or dry deposition and may include mineral dust, ions or organic components of natural or anthropogenic sources. In a large number of studies, ombrotrophic bogs have been used as environmental archives for historical deposition of trace elements and pollutants (Lee and Tallis, 1973;Pheiffer, 1981Shotyk, 1996, 1998Farmer et al, 1997;Martínez Cortizas et al, 1999, 2011Klaminder et al, 2003;Krachler et al, 2003;Kylander et al, 2005;Bindler, 2006 and references therein; De Vleeschouwer et al, 2007;Cloy et al, 2008Cloy et al, , 2009). In many of these studies the conclusions derived from element records are based on the assumption that the element is immobile, because it is associated with dust particles or strongly bound to the organic substrate.…”

“…Consequently, ratios of Pb isotopes will vary according to the origin of Pb ores, used to manufacture metal artefacts (see references in Brill and Wampler, 1967;Gale andStos-Gale, 1982, 2000;Gale, 1982, 2009;Stos-Gale et al, 1996). These isotopic imprints can be used to reconstruct ancient human activities recorded in continental reservoirs, such as peatbogs and lacustrine sediments (see references in Shirahata et al, 1980;Renberg et al, 1994;Shotyk et al, 1998;Thevenon et al, 2011;Martinez Cortizas et al, 2012). Pb concentrations measured in Fangeas peat sediments show two main trends with rather uniform values at 80e20 cm (5e 11 ppm) and a significant increase between 15 cm and the surface (13e24 ppm) ( Table 3).…”

b s t r a c tThe upper Durance valley contains the largest silverelead mines of the French Southern Alps. We investigated the characterisation and impact of these mining activities and associated forestry in the Argentière (L'Argentière-La Bessée) and Faravel (Freissinières) districts using a multidisciplinary approach that includes archaeological, palynological, geochemical, anthracological and dendrochronological studies applied to mining remnants and a peat bog (Fangeas, in the Faravel district). More specifically, we studied the occurrence of lead contamination episodes, the chronology of mining activities and their link to the evolution in woodland cover. Our chronology is based on mining archaeology, radiocarbon dating of about thirty charcoal samples and the dendrochronological analysis of more than 170 specimens of exhumed waterlogged wood. The anthracological analysis was established with more than 10,000 charcoals from firesetting. The main geochemical approach was based on the analysis of lead and its stable isotopes in sediment fractions from a peat core. The combination of palynological records and lead isotope imprints were used to characterise (i) a Roman contamination episode unknown to archaeology, (ii) the development of medieval mining activities and (iii) the reactivation of mining during the Modern period and the Industrial Revolution. Medieval mining coincides with an extension of the high mountain agropastoral areas. The in situ continuous human activities in the same industrial territory led to rational communal management of subalpine forests, but also to their parcelling that reached its peak in the High Middle Ages. Mining during the Modern period coincides with significant stress on woodland areas that also appears to be related to lumber and fuel timber production for shipyards (French Royal Navy) as well as the functioning of several military fortresses. The mining reactivation during the 19th c. matched public measures of forest protection that took shape in the afforestation programme of the uplands.
