Mercury concentrations are clearly elevated in the surface and sub-surface layers of peat cores collected from a minerotrophic (“groundwater-fed”) fen in southern Greenland (GL) and an ombrotrophic (“rainwater-fed”) bog in Denmark (DK). UsingC to precisely date samples since ca. AD 1950 using the “atmospheric bomb pulse,” the chronology of Hg accumulation in GL is remarkably similar to the bog in DK where Hg was supplied only by atmospheric deposition: this suggests not only that Hg has been… CONTINUE READING

Anthropogenic contributions to atmospheric Hg , Pb and As accumulation recorded by peat cores from southern Greenland and Denmark dated using the 14 C “ bomb pulse curve ” .
The synchroneity of the enrichments of all three elements ( Hg , Pb , and As ) suggests a common source , with coal - burning the most likely candidate .

Comparing the Pb / Ti and As / Ti ratios of the DK samples with the corresponding crustal ratios ( or “ natural background values ” for preanthropogenic peat ) shows that the samples dating from 1953 also contain the maximum concentration of “ excess ” Pb and As .
