Analytical chemistry in Japan.
The International Congress on Analytical Chemistry was held in Japan, under the sponsorship of IUPAC and the Science Council of Japan in April 1972. This is a report on the progress of analytical chemistry in Japan which I gave as the opening lecture of the Congress, in commemoration of the 20th anniversary of the Japan Society for Analytical Chemistry. Analytical chemistry courses were first e...
متن کاملWeathering reactions and hyporheic exchange controls on stream water chemistry in a glacial meltwater stream in the McMurdo Dry Valleys
[1] In the McMurdo Dry Valleys, Antarctica, dilute glacial meltwater flows down wellestablished streambeds to closed basin lakes during the austral summer. During the 6–12 week flow season, a hyporheic zone develops in the saturated sediment adjacent to the streams. Longer Dry Valley streams have higher concentrations of major ions than shorter streams. The longitudinal increases in Si and K su...
متن کاملSpatio-temporal variation in stream water chemistry in a tropical urban watershed
Urban activities and related infrastructure alter the natural patterns of stream physical and chemical conditions. According to the Urban Stream Syndrome, streams draining urban landscapes are characterized by high concentrations of nutrients and ions, and might have elevated water temperatures and variable oxygen concentrations. Here, we report temporal and spatial variability in stream physic...
متن کاملRelationships between stream water chemistry and military land use in forested watersheds in Fort Benning, Georgia
Within a military land activity context, relationships between stream water chemistry and watershed land use, topography and vegetation were explored at the Fort Benning Military Installation, Georgia. Water quality parameters, including pH, temperature, conductivity, total Kjeldahl nitrogen, total phosphorus, total organic carbon, chloride, and total suspended solids, were routinely measured i...
متن کاملAnthropogenic impact on water chemistry and benthic macroinvertebrate associated changes in a southern Nigeria stream.
The Ogba River in southern Nigeria is an important water resource for its riparian communities. This study evaluates impact of anthropogenic influences on the Ogba River using water chemistry and macroinvertebrate data sets obtained over a period of 6 months between January and June 2012. Four stations, stations 1-4, characterised by various human activities were chosen along the river. Organic...
