Early medieval origins of iron mining and settlement in central Sweden
Mercury Pollution Trends in Subarctic Lakes in the Northern Swedish Mountains
Despite many years of research about mercury pollution, data concerning high-latitude regions of Europe are limited, particularly studies of long-term temporal trends. It is not clear whether the mercury load at high latitudes follows the recent decreasing trends in European mercury emissions or whether the load is still high because of continuing global emissions. In this study we use sediments from 12 lakes, located above the Arctic Circle in t…
Pre-Industrial Atmospheric Pollution
Acid rain has caused extensive surface water acidification in Sweden since the mid-20th century. Sulfur emissions from fossil-fuel burning and metal production were the main sources of acid deposition. In the public consciousness, acid deposition is strongly associated with the industrial period, in particular the last 50 years. However, studies of lake-water pH development and atmospheric pollution, based on analyses of lake sediment deposits, h…

Using the historical atmospheric lead-deposition record as a chronological marker in sediment deposits in Europe
Atmospheric deposition of large-scale lead pollution has occurred for at least 3000 years in Europe. Metal production and smelting were the main sources until the twentieth century when emissions from vehicles using alkyl-leaded petrol became dominant. Analyses of lake-sediment and peat deposits in Sweden and other regions in Europe, as well as ice cores from Greenland, suggest synchronous temporal changes in past pollution deposition. Characteri…
Holocene climatic change reconstructed from diatoms, chironomids, pollen and near-infrared spectroscopy at an alpine lake (Sjuodjijaure) in northern Sweden
The results of a multiproxy study reconstructing the climate history of the last 9300 years in northern Sweden are presented. It is based on diatom, chironomid and pollen analyses, as well as near-infrared spec troscopy (NIRS), of a radiocarbon dated sediment core from Sjuodjijaure (67°22N, 18°04E), situated 100 m above tree-line in the Scandes mountains. Mean July air temperature was reconstructed using transfer functions established for the reg…
Sediment Evidence of Early Eutrophication and Heavy Metal Pollution of Lake Mälaren, Central Sweden
Lake Mälaren is the water supply and recreation area for more than 1 million people in central Sweden and subject to considerable environmental concern. To establish background data for assessments of contemporary levels of trophy and heavy metal pollution, sediment cores from the lake were analyzed. Diatom–inferred lake–water phosphorus concentrations suggest that pre-20th century nutrient levels in Södra Björkfjärden, a basin in the eastern par…

Near-infrared spectrometry (Nirs)
This study tests the hypothesis that lake sediments containclimate–related information that can be detected by near–infrared spectrometry (NIRS), and that NIRS can be used to infer past climatic changes from analysis of sediment cores. NIRS is a rapid and non–destructive technique that measures attributes of the chemical composition of organic materials. A training set of 76 lakes from northern Sweden, spanning a broad altitudinal gradient, was u…
Atmospheric Lead Pollution History during Four Millennia (2000 BC to 2000 AD) in Sweden
This paper discusses the history of atmospheric lead pollution, the past geographic distribution of atmospheric lead deposition in Sweden, and the fate of the pollution lead in boreal forest soils. The paper is based on analyses of 206Pb/207Pb isotope ratios and lead concentrations in lake sediments, peat deposits and soil profiles from Sweden. The first signs of atmospheric lead pollution date back to 3500 to 4000 years ago. There was a small, b…

Radiocarbon dating of a recent high latitude peat profile
The value of both high-precision (HP) and AMS 14 C determinations in the fine-resolution dating of recent peat at Stor Åmyrân, near Umeå, northern Sweden has been explored. A detailed chronology of accumu lation, based on 14 C, an occurrence of the Askja AD 1875 tephra and 241 Am measurements has been derived for the last 700 years. This shows significant changes in the mass balance of the peat profile, with minimum rates of net carbon sequestrat…
A palaeolimnological test of the influence of Norway spruce (Picea abies) immigration on lake-water acidity
The effect of recent land use and subsequent vegetation changes per se on surface-water acidity is difficult to ascertain because of the complicating factor of enhanced levels of anthropogenic acid deposition that occurs at the same time as land-use changes. Expansion of conifers is a major contemporary vegetation change in Sweden and other countries. The immigration of Norway spruce (Picea abies (L.) Karst.) into Sweden about 3000 years ago prov…
