The phytoremediation potential for strontium of indigenous plants growing in a mining area

Abstract

a b s t r a c tThis study investigated the distribution and accumulation of strontium (Sr) in the shoots and roots of Euphorbia macroclada (EU), Verbascum cheiranthifolium (VR), and Astragalus gummifer (AS), with respect to their potential use in phytoremediation. Plant samples and their associated soils were collected from the arid and semi-arid Keban mining area and were analyzed inductively by ICP-MS for Sr. Mean Sr values in the shoots, roots and soil were, respectively, 453, 243 and 398 mg kg −1 for E. macroclada; 149, 106 and 398 mg kg −1 for V. cheiranthifolium; and 278, 223 and 469 mg kg −1 for A. gummifer. The enrichment factors for root (ECR) and shoot (ECS) of these plants were lower than 1 or close to 1, except for the shoot of E. macroclada. The mean translocation factors (TLF) of these plants were higher than 1 and 2.08 for E. macroclada, 1.47 for V. cheiranthifolium, 1.18 for A. gummifer. It thus appeared that the shoots of these plants can be an efficient bioaccumulator plant for Sr and it can be used in cleaning or rehabilitating of the contaminated soil and areas by Sr because of their high translocation factors.Published by Elsevier B.V.

Removal of natural organic dyes from wool–implications for ancient textile provenance studies

“…Plants could potentially be characterized by a strontium isotopic composition that significantly differs from that of a raw material that is exposed to dyeing, in this case wool. Strontium concentrations are very low both in human and animal hair (less than 1 ppm and up to a few ppm; Attar et al, 1990;Christian et al, 1997;Morita et al, 1986;Rosborg et al, 2003) in contrast to plants which can have concentrations up to 30 ppm (Sasmaz and Sasmaz, 2009). The present study focuses on the removal of dyes from wool that could act as potential contaminants when studying the provenance of ancient textiles by the strontium isotopic system.…”

Heavy metal pollution and physiological changes in the leaves of some shrub, palm and tree species in urban areas of Adana, Turkey

“…It is released into the environment via waste including, chimney gases and compost (Sasmaz and Sasmaz, 2009;WHO, 2010). Sr exists in different isotypes in the soil and causes toxicity in plants at a concentration above 30 mg kg -1 (Shacklette et al, 1978).…”

Qualitative and Quantitative Content Determination of Macro-Minor Elements in Bryonia Alba L. Roots using Flame Atomic Absorption Spectroscopy Technique

“…33 Additionally, it is also affected by the properties of soil such as organic matter content, ionic composition, and pH. 34 The concentration of strontium in Bryonia alba L. roots sample was 0.78 mg/ 100 g dry weight of the sample.…”
