Title : Tracing the sources of sulfur in Beijing soils with stable sulfur isotopes
Journal : Journal of Geochemical Exploration
Comment :
Stable sulfur isotope analyses were applied in order to trace local sulfur sources and to identify sulfur turnover rates in Beijing soil. Anthropogenic sources and atmospheric deposition are the main processes responsible for the occurrence of sulfide, organic and sulfate sulfur in three soil profiles located in the vicinity of a steel company in Beijing, China. This input results in an atypical invariable sulfur isotopic composition along the vertical profiles. The δ34S values of soil sulfate from the industrial area revealed that both the topsoil and deep soil have been affected by industrial activities. This study suggests that an assessment of the vertical distribution of sulfur concentration and sulfur isotopic composition of bulk soil in soil profiles from industrial and non-industrial areas can trace the sources and fate of different sulfur species in soil.
