Boron (B) concentrations were investigated in both shoots and roots of Euphorbia macroclada, Verbascum cheiranthifolium, and Astragalus gummifer grown in soil of the Keban, Turkey, Lead-zinc-copper-fluoride mining area, which has an arid climate. Soil B concentrations were also investigated. Plants and their associated soil samples were collected and analyzed by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). Total B concentrations of soils in the study area were very low (mean: 4.97 mg kg-1) as compared with those in surface soils in other countries. Boron concentrations of plant organs were several times higher than those in their associated soils. The mean values of B concentrations in roots of E. macroclada, V. cheiranthifolium, and A. gummifer were 25, 70, and 69 mg kg-1, respectively, while those in shoots were 75, 115, and 77 mg kg-1, respectively. Results indicate that roots and shoots of plants grown in soils with low B concentrations can be used both as biomonitors for environmental contamination and biogeochemical indicators for B.
