Heavy metals (Fe, Zn, Mn, Cu, Ni, Co, Pb, and Cd) were analyzed in 61 samples of plant species of the family
Cruciferae
and 23 samples of North Caucasian soils developed on ultramafic, mafic, and felsic bedrocks. The study revealed the dependence between the chemical composition of plants, geochemical environments, and the taxonomic position of species. We identified two species,
Arabis sagittata
, an accumulator of Zn, Cu, Ni, and
Alyssum murale
, a hyperaccumulator of Ni, which can be effective in phytoremediation of heavy-metal contaminated soils.
