ABSTRACT

The concentration levels of the following metals: Cd, Pb, Zn, Mn, Fe and Ni in falling dusts, soil and dandelion (Taraxacum officinale Webb.) were examined in selected areas of Southern Podlasie Lowland. The research was conducted from 1995 to 1999. The metals were marked by means of the AAS technique. The deposition of Cd and Pb metals did not exceed the values standardized in the Polish legislation, and the mean metal concentration in the soil was the same as the natural content. The mean metal concentration in dandelion leaves and root was within the values accepted as background in professional literature. It was proved that in agricultural lands that were not excessively loaded with heavy metals, the metal level in the root of the plant is of higher significance than in the leaves when using dandelion for bio-indicatory purposes.

Key words: Southern Podlasie Lowland, heavy metals, falling dusts, soil, dandelion (Taraxacum officinale Webb.), enrichment coefficients, bio-indication..
