Since the 1970s liming has been practised on a large scale in Sweden to mitigate acidification and several thousand lakes and streams are limed repeatedly. The Swedish monitoring program ISELAW (Integrated Studies of the Effects of Liming Acidified Waters) studies the long-term effects of liming. This paper summarizes the paleolimnological part of the program. Sediment cores from 12 lakes were analysed to study the development of the lakes from pre-industrial time until the present, and address… 
Monitoring compared with paleolimnology: implications for the definition of reference condition in limed lakes in Sweden
This study shows that monitoring series are usually too short to define reference conditions for lakes, and that paleolimnological studies are useful to set appropriate goals for restoration and for evaluation of counter measures.
Comparing pre-industrial and post-limed diatom communities in Swedish lakes, with implications for defining realistic management targets
In the 1960s and 1970s, acidification was identified as a major environmental problem in Scandinavia, Great Britain and North America. In Sweden, a liming program was launched in order to counteract
Assessing past ecological changes in Lake Isojärvi and its suitability as a Finnish lake reference site using sedimentary diatoms
Paleolimnology studies the past of inland aquatic ecosystems through the physical, chemical and biological information stored into the sediments of lakes. The usefulness of paleolimnological methods
Environmental footprint of small-scale, historical mining and metallurgy in the Swedish boreal forest landscape: The Moshyttan blast furnace as microcosm
The history of mining and smelting and the associated pollution have been documented using lake sediments for decades, but the broader ecological implications are not well studied. We analyzed
Biological responses to liming in boreal lakes: an assessment using plankton, macroinvertebrate and fish communities
The limited structural and functional food web similarity among lake types supports the argument that liming constitutes an ecosystem-level disturbance, and suggests that impacts derived from global change are likely to lead to novel environmental situations.

SUMMARY 1. One of the greatest challenges faced by limnologists, as well as most ecologists and environmental scientists, is finding data with time scales appropriate to their questions. Because of
Ecological benefits and risks arising from liming sugar maple dominated forests in northeastern North America
Liming, the application of carbonate materials (e.g., CaCO3, CaMg(CO3)2) to soils and surface waters, has been used extensively in Europe, and to a lesser extent in Canada and the United States, to
The complementary power of pH and lake-water organic carbon reconstructions for discerning the influences on surface waters across decadal to millennial time scales
Abstract. Lysevatten, a lake in southwest Sweden, has experienced both acidification and recent changes in the amount of lake-water organic carbon (TOC), both causing concern across Europe and North
Quantifying human-induced eutrophication in Swiss mountain lakes since AD 1800 using diatoms
Sedimentary diatom assemblages from three lakes in the southeastern Swiss Alps were analysed at high temporal resolution since AD 1800. Altered land-use patterns, increasing population and


Long-Term Ecological Effects of Liming — the Iselaw Programme
The Swedish liming programme was initiated in 1977 to counteract the effects of anthropogenic acidification on aquatic ecosystems until the acid deposition has been reduced. Ecosystem development in
Integrated studies of the effects of liming acidified waters (ISELAW-programme)
To assess the long-term (>15 years) effects of liming, an integrated programme for studies of the effects of liming in acidified waters (ISELAW) was initiated in 1989. At present, 14 lakes and 14
The Swedish liming programme
To mitigate the acidification problem in surface waters the Swedish government is funding a liming programme. Limestone or dolomite powder has been applied to acidified waters since 1976 and on a
Post-1970 water-chemistry changes and palaeolimnology of several acidified upland lakes in the U.K
Responses of four lakes to post-1970 changes in acid deposition, afforestation and liming are examined by using water quality measurements and palaeolimnological analysis. pH and non-marine sulphate
An experimental and palaeoecological study of algal responses to lake acidification and liming in three central Swedish lakes
L liming had little quantitative or qualitative effect on the phytoplankton diversity at Njupfatet, but did result in the loss of the dominant contributor to algal biomass, Merismopedia tenuissima.
Temporal and spatial trends of lake acidity in northern Sweden
Changes in lake-water pH, alkalinity and colour were inferred from diatoms in surface sediment samples and sediment samples from pre-industrial times from 118 northern Swedish lakes. This
Prehistoric increases in the pH of acid-sensitive Swedish lakes caused by land-use changes
IN the past few decades, there has been considerable debate about whether vegetational and soil changes associated with changing land-use can cause surface-water acidification in lakes1,2. Although
Phytoplankton in 63 limed lakes in comparison with the distribution in 500 untreated lakes with varying pH
As a result of the different weathering of lime in soils and varying acid deposition, the pH of Swedish oligotrophic lake waters has a broad range from ca. 4 to 8.5. Phytoplankton species occur in
Four thousand years of atmospheric lead pollution in northern Europe: a summary from Swedish lake sediments
This paper presents a large palaeolimnological study of the pre-industrial and industrial history of atmospheric lead pollution deposition in Sweden. Both lead concentrations and 206Pb/207Pb ratios
Pre-Industrial Atmospheric Pollution: Was It Important for the pH of Acid-sensitive Swedish Lakes?
An argument is presented, using the sediment record, that large-scale atmospheric acid deposition has impacted the environment since at least Medieval times and contributed to alkalization, i.e. increased pH and productivity of the lakes.
