Direct monitoring of stream water chemistry is an increasingly important tool for securing stream water quality and assessing stream ecological functioning as it relates to overall ecosystem health. S...
CHEMISTRY OF GROUNDWATER IN IGNEOUS ROCK AT ANGERED,GOTHENBURG
CHEMISTRY OF GROUNDWATER IGNEOUS ROCK
2009/10/29
Within an area of about 5 km2, 25 wells were drilled to depths of about
90 m for groundwater observation. The wells were sampled and analyzed,
and from the results it could be concluded that the ion...
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 ...

Runoff Chemistry at a Mini-Catchment Watered with Unpolluted Precipitation
Runoff Chemistry Mini-Catchment Unpolluted Precipitation
2009/10/28
600 mm of artificial, "unpolluted" precipitation with a chemical composition
of assumed preindustrial quality ((HC] = 9 peql-I. ISO,] = 11 peql-') was
sprayed on a "mini-catchment" (98 m2) over a pe...

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 ...

Two subarctic fens (one nutrient-poor, one nutrient-rich) were sampled from
October, 1984 to July, 1985 near Schefferville, northern Quebec. The changes
in concentations of chemicals (pH, conductanc...
Difficulties in Deducing Temporal Changes in Precipitation Chemistry from Snow and Ice Cores:The Spatial Variability Problem
Temporal Changes Precipitation Chemistry Snow and Ice Cores Spatial Variability Problem
2009/10/26
Depth profiles of chemical impurities found in snow and ice have usually been
interpreted simply in terms of temporal changes in atmospheric concentrations
of the species of interest. Measurements o...
