A model of sulphur solubility for hydrous mafic melts: application to the determination of magmatic fluid compositions of Italian volcanoes
sulphur hydrous basalts volcanic gas
2015/9/10
We present an empirical model of sulphur solubility that allows us to calculate f S2 if P, T, fO2 and the melt composition,
including H2O and S, are known. The model is calibrated against three main ...
Continental scale Antarctic deposition of sulphur and black carbon from anthropogenic and volcanic sources
Continental scale Antarctic deposition sulphur black carbon anthropogenic and volcanic sources
2010/3/16
While Antarctica is often described as a pristine environment, there is an increasing awareness of the potential threats from local pollution sources including tourist ships and emissions associated w...
Based on data from the Swedish water quality covering 78% of the Swedish
area, the discharge of sulphur has been computed for the period 1969 to 1977.
The trend for this period gives a figure for 19...

Comparison of sulphate concentrations in groundwaters and atmospheric precipitation
suggests that about 30 % of groundwater sulphate may be of atmospheric
origin. Another source of sulphate ion is t...

The impacts of future climate change and sulphur emission reductions on acidification recovery at Plastic Lake, Ontario
climate change Plastic Lake sulphur emission
2009/4/29
Climate-induced drought events have a significant influence on sulphate export from forested catchments in central Ontario, subsequently delaying the recovery of surface waters from acidification. In ...
Critical loads of sulphur and nitrogen for freshwaters in Great Britain and assessment of deposition reduction requirements with the First-order Acidity Balance (FAB) model
critical loads acidification nitrate FAB model
2009/3/24
The critical loads approach is widely used within Europe to assess the impacts of acid deposition on terrestrial and freshwater ecosystems.
Sulphur and nitrogen fluxes and budgets in the Bohemian Forest and Tatra Mountains during the Industrial Revolution (1850-2000)
emission deposition acidification
2009/3/24
Major fluxes of sulphur and dissolved inorganic nitrogen were estimated in Central European mountain ecosystems of the Bohemian Forest (forest lakes) and Tatra Mountains (alpine lakes) over the indust...
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 the effects of atmospheric sulphur and nitrogen deposition on selected lakes and streams of the Central Alps (Italy)
MAGIC northern Italy acidification recovery nitrogen
2009/3/12
The dynamic model MAGIC was calibrated and applied to selected sites in north-western Italy (3 rivers, 10 alpine lakes) to predict the future response of surface water to different scenarios of atmos...

Satellite-based detection of volcanic sulphur dioxide from recent eruptions in Central and South America
Satellite-based detection volcanic sulphur dioxide eruptions Central and South America
2010/1/27
Volcanic eruptions can emit large amounts of rock fragments and fine particles (ash) into the atmosphere, as well as several gases, including sulphur dioxide (SO2). These ejecta and emissions are a ma...
