Abstract
Sulphur is an element found in surplus in anthropogenic areas and one of the minerals responsible for the development of acid rains. The analysis of stable S isotopes provides a powerful tool for studying various aspects of the biogeochemical circulation of sulphur. δ34S values and S concentrations were determined in a 90-day experiment with the native moss Pleurozium schreberi from rural, urban and industrial sites in Upper Silesia in southern Poland. At the same time P. schreberi from a control site was transplanted to the same rural, urban and industrial sites and the δ34S values and S concentrations were determined in the same 90-day experiment. 34S enrichment (up to 4.7â°) in the mosses tested indicates that these plants responded to environmental pollution stress. Sulphur isotopic composition in the transplanted P. schreberi was related to S concentrations in this species after 90 days of the experiment. Higher δ34S values and S concentrations were noted in native mosses than in those transplanted from rural and urban sites while an opposite situation was reported in industrial sites. The transplanted P. schreberi was a better sulphur bioindicator than the native moss in more polluted industrial sites and worse in less polluted rural and urban sites.
