Transjøen,a Groundwater Influenced Lake with Special Redox and Sulphate Conditions
Groundwater Influenced Lake Special Redox Sulphate Conditions
2009/10/29
Transjeen, a lake in S.E. Norway investigated hydrographically from October
1969 to October 1971, consists of two basins, both of which are meromictic (lake
with lower layer which does not participa...
Modelling the Effects of Acid Sulphate Soils on River Acidity in Finland
Effects of Acid Sulphate Soils River Acidity
2009/10/26
Acid sulphate (AS) soils cover extensive areas of the coastal plains in western
Finland. These soils constitute an environmental hazard due to their ability to
relcase acidity when exposed to atmosp...
Acidification in Three Lake District Tarns：Historical Iong term trends and modelled future behaviour under changing sulphate and nitrate deposition
Acidification nitrate deposition sulphate
2009/6/8
Three upland Lake District Tarns, Scoat, Greendale and Burnmoor, have been evaluated using MAGIC (Model of Acidification of Groundwater In Catchments) to reconstruct past, present and future chemical ...
Determination of bromide, chloride, fluoride, nitrate and sulphate by ion chromatography: comparisons of methodologies for rainfall, cloud water and river waters at the Plynlimon catchments of mid-Wales
bromide chloride fluoride nitrate sulphate Plynlimon catchments
2009/5/6
The results of determination of bromide, chloride, fluoride, nitrate and sulphate using ion chromatography (IC) are compared with those obtained by colorimetric and inductively coupled plasma optical ...
Climate control on sulphate and nitrate concentrations in alpine streams of Northern Italy along a nitrogen saturation gradient
surface waters nitrate concentrations sulphate nitrogen saturation gradient
2009/4/29
The role of meteorology, hydrology and atmospheric deposition on the temporal pattern of SO4 and NO3 concentrations was investigated for three streams draining alpine catchments in Northern Italy.

Coherent responses of sulphate concentration in Norwegian lakes: relationships with sulphur deposition and climate indices
recovery acid coherence
2009/3/12
The coherence or synchrony in the trends in SO42– concentration in a set of 100 lakes in Norway that have a long-term chemical record was evaluated. Using a statistical technique that compares pattern...
Coherent response of lakes in Ontario, Canada to reductions in sulphur deposition: the effects of climate on sulphate concentrations
Atmospheric deposition lake recovery temporal trends
2009/3/12
Sulphate deposition in south-central Ontario declined between 1976 and 2000 by more than 50%, whereas lake sulphate (SO42–) concentrations decreased by, on average, only half as much. To investigate t...
Modelling sulphate stream concentrations in the Black Forest catchments Schluchsee and Villingen
sulphate release organic S mineralisation
2009/3/12
The sulphate (SO4) released by mineralisation and desorption from soil can play an important role in determining concentrations of SO4 in streams. The MAGIC model was calibrated for two catchments in ...
