Interactions of rare earth elements with living organisms and emerging biotechnical applications

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1251-1274, September 2025.
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

Analysis of Mercury-Rich plants and mine tailings using the Hydride-Generation AAS method

open access: yesBrazilian Archives of Biology and Technology, 2009
A hydride-generation atomic absorption spectroscopy (AAS) method was developed for the analysis of total Hg in liquid matrices of mercury-rich plants and mine tailings samples. The detection limit for this method was as low as 11.4 ng/mL.

Plant growth regulators-assisted phytoextraction

open access: yesBiologia plantarum, 2014
Plant growth regulators (PRG)-assisted phytoremediation is a technique that could enhance the yield of heavy metal accumulation in plant tissues. So far, a small number of experiments have helped identify three groups of plant hormones that may be useful for this purpose: auxins, cytokinins, and gibberellins.

Stability of Vanadium in Alkaline Soils Amended With Biochar and Metal Oxide Nanoparticles Under Simulated Seasonal Temperature Fluctuations

open access: yesRemediation Journal, Volume 36, Issue 1, Winter 2025.
ABSTRACT Vanadium (V) is a re‐emerging environmental contaminant due to its high mobility and potential toxicity in soil and water systems. This study examined the stability of immobilized V in soils amended with biochar (BC, 5% w/w), and biochar combined with iron (BCFe), aluminum (BCAl), or titanium (BCTi) oxide nanoparticles (1% w/w), under ...

Effect of EDTA treatment method on leaching of Pb and Cr by Phragmites australis (Cav.) Trin. Ex Steudel (common reed)

open access: yesCaspian Journal of Environmental Sciences, 2015
One of the major problems about the chelant-enhanced phytoextraction is the potential metal leaching associated with chelant application. A glasshouse pot experiment was conducted to investigate phytoextraction efficiency of common reed (Phragmites ...

Biomass yield and metal phytoextraction efficiency of Salix and Populus clones harvested at different rotation lengths in the field experiment

open access: yesChemical and Biological Technologies in Agriculture
Background Phytoextraction belongs to environmentally well-accepted remediation technologies to remove metals from contaminated soils. Due to long-time requirement, sufficient data for proper phytoextraction evaluation are missing.

The results of an NPK-fertilisation trial of long-term crop rotation on carbonate-rich soil in Estonia

open access: yesActa Agriculturae Scandinavica. Section B, Soil and Plant Science, 2019
Soil is an element of crop cultivation that demands consistent fertilisation to compensate for the nutrients that are removed by the harvest. Changes in soil because of prolonged fertilisation can only be estimated by long-term field trials.

Physiological Effect of Thallium in the Facultative Hyperaccumulator Silene latifolia

open access: yesPhysiologia Plantarum, Volume 177, Issue 5, September/October 2025.
ABSTRACT The metallicolous populations of the facultative Tl hyperaccumulator Silene latifolia are extraordinarily tolerant and capable of accumulating up to 80,000 μg Tl g−1 in nature. A growth stimulatory effect of Tl was observed, and this study set out to determine possible mechanisms.

Heavy metals phytoextraction from heavily and moderately contaminated soil by field crops grown in monoculture and crop rotation

open access: yesSoil and Water Research, 2011
The uptake of Pb, Cd, Zn and biomass production of the plants Brassica juncea v. Opaleska, Triticale hexaploides var. Gabo and Helianthus annuus v. Maritza were observed in a field (trial) and a pot experiments during four years. The plants were grown in
