Abstract
The aim of this work was determination of trace metals (Pb, Zn, Ni, Cu and Fe) in different plants collected in the vicinity of phosphogypsum waste heap in Wiślinka (northern Poland). The concentrations of trace metals were determined by two methods: AAS (atomic absorption spectrometry) and OES-ICP (atomic emission spectrometry with inductively coupled plasma). Enhanced levels of iron were observed in all the analyzed samples. This fact can be explained by the higher content of iron in the groundwaters of Żulawy Wiślane, where concentration of iron was 60 mg/l. The trace metals concentrations in plant samples from phosphogypsum waste heap recorded in this study are generally higher than in control sites. In this study the relationship is shown between atmospheric trace metals deposition and elevated trace metals element concentrations in plants and topsoils, especially in the vicinity of phoshpogypsum waste heap.
Highlights
Trace metals may be defined as metals occuring at 1000 μg g–1 or less in the earth' s crust and may be classified as heavy or light with respect to density
The data stated that the transfer of trace metals into plants via roots is higher than transfer from atmospheric fallout
Among meadow plants the highest contents of trace metals were noticed for plants which were collected in the vicinity of phosphogypsum waste heap
Summary
Trace metals may be defined as metals occuring at 1000 μg g–1 or less in the earth' s crust and may be classified as heavy or light with respect to density. Trace metals in the environment are the result of natural geochemical processes, as well as of numerous anthropogenic sources (Allowey and Ayres, 1999). The natural content of heavy metals in the environment is very differentiated, because of the large diversity of properties of environmental media (air, soil, plants, or water) (Wolak et al, 1995). In contaminated areas bodies of plants produced adaptation and defense mechanisms which involves precipitation of excess metal in crystalline forms or salt deposition on the tips of the leaves. This effect can explain improper size and form of plants in comparison with those grown on uncontaminated areas (Kabata-Pendias and Pendias, 1993)
