Abstract:
Concentration
of the metals Al, Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, Sr, Zn and V as well as N,
P, K, Ca, Mg, Fe and S were measured in soils and in two tree species (leaves
of Betula pendula and Salix caprea and two herbs (whole
aboveground parts of Solidago
canadensis and Tanacetum vulgare)
sampled from dumps in the Wa³brzych coal mine area (Lower Silesia, SW
Poland). These plants, as used to evaluate the distribution of elements in
the examined dumps, contained elevated levels of Cd, Co, Cu, Mn, Ni, Pb and
Zn. Especially the highest levels of Mn in
Betula pendula seriously exceed background values. Betula pendula characterized also the highest enrichment ratio
for Mn, Salix caprea for Ni and Sr
and Tanacetum vulgare for Cu. Test-t indicated that from both herbs Tanacetum vulgare accumulated much
more K, N, S and Zn than Solidago canadensis and of both trees Salix caprea accumulated significantly
more Cd, Cu, K and Ca than Betula
pendula, while this last species accumulated significantly more Fe and Mn
than Salix caprea. A post hoc LSD test indicated that
all examined plants had similar enrichment ratios for Al, Pb and V. |
