Radium and radon exhalation studies of soil
Background: Everyone is exposed to radon because it is present everywhere with varying concentrations. Radon and its progeny are well established as lung carcinogenic. Materials and Methods: Track etch technique using LR-115 plastic track detectors has been used to measure the effective radium content and radon exhalation rates in soil samples collected from urban area of Etah district...
متن کاملSoil Compaction and Soil Tillage – Studies in Agricultural Soil Mechanics
Keller, T. 2004. Soil Compaction and Soil Tillage Studies in Agricultural Soil Mechanics Doctoral dissertation. ISSN 1401-6249, ISBN 91-576-6769-1 This thesis deals with various aspects of soil compaction due to agricultural field traffic, the draught force requirement of tillage implements and soil structures produced by tillage. Several field experiments were carried out to study the mechanic...
متن کاملLaboratory and lysimeter studies of glyphosate and aminomethylphosphonic acid in a sand and a clay soil.
Due to the increasing concern about the appearance of glyphosate [N-(phosphonomethyl)glycine] and its major metabolite aminomethylphosphonic acid (AMPA) in natural waters, batch laboratory and lysimeter transport studies were performed to assess the potential for leaching of the compounds in two agricultural soils. Unlabeled and 14C-labeled glyphosate were added at a rate corresponding to 1.54 ...
متن کاملModelling Studies on Soil-mediated Response to Acid Deposition and Climate Variability
The impact of acidifying atmospheric precipitation and climate variability on forest soil was studied using three approaches: (i) dynamic process-oriented modelling, (ii) static vulnerability assessment, and (iii) non-linear response pattern identification. The dynamic soil acidification model MIDAS is presented, with applications at the plot and catchment scale in Norway, Sweden and Finland, w...
متن کاملAcid rain on Acid soil: a new perspective.
Acid rain is widely believed to be responsible for acidifying soil and water in areas of North America and northern Europe. However, factors commonly considered to make landscapes susceptible to acidification by acid rain are the same factors long known to strongly acidify soils through the natural processes of soil formation. Recovery from extreme and widespread careless land use has also occu...
