The study of isotopes in soils has become an essential tool in understanding both geological time scales and contemporary environmental processes. By utilizing various isotopes, researchers can glean information about such varied topics as soil formation, nutrient cycling, and past climate conditions. This article focuses on prominent isotopic systems employed in soil studies, including ...
However, since the 1970s correlation spectrometers have been used to measure the levels of sulfur dioxide in the volcanic plume as scientists began to understand that higher levels of gas emission from a volcanic site indicates a higher chance of eruption. In more recent times, using geochemical models, a growing body of research and evidence shows measuring the ...
Dhapa, is a well known municipal solid waste (MSW) disposal site in the eastern part of the city of Kolkata. Geochemical study reported here shows that in its sediments, the concentration of Zn, Cu and Pb greatly exceed the average worldwide shale concentration. The water samples collected from tubewells, dugwells, pond and canals have elevated concentrations of Zn, Mn, Cr, Cu, Ni and Pb. The ...
Analytical techniques were combined with geochemical modelling to study the release mechanisms of pollutants from an abandoned gold mining tailings storage facility near Johannesburg. Inverse modelling of sampled tailings pond water and experimental single extractions using various solutions indicated which combination of naturally occurring leaching solutions were likely to give rise to the ...
Abstract: In the present investigation, bulk and chemical partitioning of elements in the Shefa-Rud riverbed sediments are studies. Higher concentrations of elemental concentrations have been observed in estuarine zone when compared with riverine sediments (except for Al, Fe, Pb and Mn). Manganese is mobilized under anoxic conditions prevailing in the Caspian Sea. Lithogenous materials are ...
A study has been carried out of a waste disposal site, located in the valley of a small creek, 3 km south of Canakkale city centre. The surface area of the site was around 101000 square metres, and the total amount of waste deposited at the site since 1990 was approximately 1001000 tons. The major risks of the dump are its closeness to the university campus area to the south, the airport to the ...
In the present study, an attempt was made to delineate soil contamination around the ash pond of a coal-based thermal power plant. The topsoil in the study area was found to be contaminated to varying degrees from ash disposal. The soil drawn from various profiles was largely contaminated by ash fall out, predominantly in the prevalent wind direction. Pb, Zn, Cu, Ni, Co, Mn, Cr, V and Ba were ...
