THE CONTENT OF SOME NATURAL RADIOACTIVE ELEMENTS,ESPECIALLY 222Rn,IN SOME POTABLE WATERS IN SWEDEN
NATURAL RADIOACTIVE ELEMENTS Rn POTABLE WATERS IN SWEDEN
2009/10/29
The content of 222Rn in drinking water from 118 wells in southeastern
Sweden has been measured. The radiation dose from 222Rn is completely
dominant in comparison with the dose from other nuclides e...
Chemical changes in water circulating deep in the fissures of the solid
rock are studied. The ultimate chemical composition is determined by
the conditions of percolation through the soil zone. For ...
On the Role of Equilibrium Reactions in Bore-Hole Waters in the Skellefte-Field,Northern Sweden
Equilibrium Reactions Bore-Hole Waters Skellefte-Field
2009/10/28
In a series of bore holes in an acid-intermediate volcanite rock type measurements
of pH and pe (in situ), main ionic constituents, silicic acid and aluminium
were made. The bore holes covered the p...

Mixing Effects Carbonate Dissolving Waters 13C/12C Compositions
2009/10/27
Seasonal variations in chemistry and r1atios o f total inorganic carbon of
carbonate dissolving waters are considered in the frame-work of a simplified
approach dealing explicitly with major ionic s...
Variations in the 87Sr/86Sr Ratio in Lake Waters from Central Sweden
Variations 87Sr/86Sr Ratio Central Sweden
2009/10/27
The 87Sr/86Sr sratiros of lake waters from eastern Central Sweden, a region
consisting mainly of 1.7-2.0 x lo9 years old granitoid rocks are reported and
discussed. The ratios range from 0.722-0.739...

Chemistry Total Dissolved Carbon Lublin City
2009/10/27
The pH, 613c of total dissolved carbon and HCO;, Ca2*, Ca2+ + Mg2+ contents
in spring waters were investigated. Changes of these values were recorded
for 8 months of 1982 and 1983. The changes were ...
The Solubility and Hydrolysis of Aqueous Aluminium Hydroxides in Dilute Fresh Waters at Different Temperatures
Solubility Hydrolysis Aqueous Aluminium Hydroxides Dilute Fresh Waters
2009/10/26
This study is mainly focusing on the effect of temperature and pH on the
chemistry of AI(OH),(s) using available thermodynamic data.
The calculations show that a doubling of the [Hf] or a decrease i...

Modelling the effects of climate on long-term patterns of dissolved organic carbon concentrations in the surface waters of a boreal catchment
Dissolved organic carbon artificial neural networks
2009/4/29
Dissolved organic carbon concentrations ([DOC]) in surface waters are increasing in many regions of Europe and North America. These increases are likely driven by a combination of changing climate, r...
