Differences in concentrations of heavy metals between native and transplanted Pohlia nutans [Hedw.] Lindb. - a case study from a dump exposed to industrial emissions in Poland

During a period of 60 days assays were carried out with the moss Pohlia nutans transplanted from an uncontaminated control site to a dump consisting of a heavily polluted mine and smelter wastes located near Wałbrzych in southwestern Poland. Within the same period also samples of native P. nutans growing on the dump substrate were collected together with the same species from a control site. Concentrations of Al, Fe, Cd, Co, Cr, Cu, Mn, Ni, Pb, V, and Zn, as well as N, P, K, Ca, Mg and S, were determined in P. nutans, the dump substrate and the soil of the control site. Atmospheric deposition was the main contribution to the levels of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn in the native and transplanted P. nutans on the examined dump. The obtained results indicate that the transplanted P. nutans accumulated significantly more Al, Cd, Co, Cr, Fe, Ni, Pb and Zn than the native moss.
