Climate changes, lead pollution and soil erosion in south Greenland over the past 700 years
A peat core from southern Greenland provided a rare opportunity to investigate human-environment interactions, climate change and atmospheric pollution over the last ~700 years. X-ray fluorescence, gas chromatography-combustion, isotope ratiomass spectrometry, peat humification and fourier-transform...

A peat core from southern Greenland provided a rare opportunity to investigate human-environment interactions, climate change and atmospheric pollution over the last ~700 years. X-ray fluorescence, gas chromatography-combustion, isotope ratiomass spectrometry, peat humification and fourier-transforminfrared spectroscopy were applied and combined with palynological and archaeological evidence. Variations in peat mineral content seem to be related to soil erosion linked with human activity during the late Norse period (13th–14th centuries AD) and the modern era (20th century). Cooler conditions during the Little Ice Age (LIA) are reflected by both slow rates of peat growth and carbon accumulation, and by low bromine (Br) concentrations. Spörer and Maunder minima in solar activity may be indicated by further declines in Br and enrichment in easily degradable compounds such as polysaccharides.
