Abstract
The genus Taraxacum is used in the assessment of soil contamination with heavy metals. There are relatively few studies using sections or species representing this genus. The presented research was conducted in Poland on two habitats, varied in terms of nutrients and metals content. The content of selected metals in leaves and roots of Taraxacum sect. Taraxacum was determined. It was found that in the conditions of increased content of metals in the soil, the analysed species representing sect. Taraxacum accumulate higher amounts of metals in their leaves and roots. Factors of translocation of selected metals from roots to leaves of Taraxacum species, representing the Taraxacum section, are affected by i.a. soil reaction and the content of Corg, Ntot. in the soil. No influence of soil properties on metal biological concentration factor was observed.
Highlights
The plant commonly used in environmental quality assessment is Taraxacum sp
The following research hypotheses were adopted in the study: (I) habitats differ in the content of heavy metals in the soil, (II) plants representing the Taraxacum section occurring at chemically diversified habitats accumulate varied amounts of different heavy metals in their roots and
Soil samples collected at the same sites as dandelions were characterised by neutral or slightly alkaline reaction
Summary
The plant commonly used in environmental quality assessment is Taraxacum sp. The genus Taraxacum is one of the largest and taxonomically most diverse apomictic complexes. The results of the analysis of selected soil chemical parameters and the content of metals in dandelion leaves and roots were calculated per 1 g d.m. of a given analysed sample.
