The patterns in accumulation of chemical elements by higher plants and their responses in biogeochemical provinces

Abstract

The patterns in establishment of elemental composition in plants depending on specific landscape and geochemical features, different types of climate, and plant systematic affiliation are analyzed with the focus on hyperaccumulator plants, forming specialized endemic floras in biogeochemical provinces with excess trace element concentrations. The plant metal tolerance is an integrated problem. Within the consid ered research field, the metal tolerant plants present a scientific interest, being the centers for emergence of new varieties (evolutionary aspect). Different responses (floristic, physiognomic, etc.) observed in plants growing in deposits are indicators for searching for ores. Hyperaccumulators are promising in phytoremedi ation of polluted soils.

Significance of Trace Element Composition of Soils and Problems of Their Remediation

“…In particular, the Alpine pennycress is a Zn & Cd hyperaccumulator. Also, a Zn, Cu & Ni hyperaccumulator and a Ni hyperaccumulator were identified (Arabis sagittata and Alyssum murale, respectively) (Alekseeva-Popova et al, 2015;Ufimtseva, 2015;Narasimha, Prasad, 2005).…”

“…The biological absorption coefficient exceeds 1 (Alekseeva-Popova et al, 2015; Ufimtseva, 2015). There are as many as 4 hyperaccumulating species for As, 1 for Cd, 30 for Co, 34 for Cu, 14 for Pb, > 320 for Ni, 20 for Se, 11 for Zn and 10 for Mn.…”

Biogeochemical accumulation of trace elements in soils and plants of the Russian Far East

“…Plants are the most important intermediate link through which chemical elements pass from soil, water and air into the body of animals and humans. Therefore, in conditions of constant anthropogenic pollution of the environment, it is possible to include a number of chemical elements in the human food chain, which poses a potential health hazard [4,5].…”

Serpentine Overburden Products—Nature-Inspired Materials for Metal Detoxification in Industrially Polluted Soil

“…Plants growing in serpentine soils form a special type of community: serpentine flora [ 20 , 21 ]. Plants of the nickel flora are the most widespread, some of them belonging to the category of hyperaccumulators.…”
