“…It is now possible to access to tons of Ni rich biomass in the USA and in Europe. As an example, crop yields of the nickel hyperaccumulating Alyssum murale can reach at least 20 t ha (1 or 400 kg Ni/ha with ordinary fertilizers and management practices (4). Similar studies are under process for zinc hyperaccumulating plants T. caerulescens and Anthyllis vulneraria.…”

Green Lucas reagent was prepared from Zinc hyperaccumulating plant, Thlaspi caerulescens. It is an effective and reusable reagent for the chlorination of tertiary, secondary, and primary alcohols. The results are the first use of contaminated biomass in organic synthesis and can constitute an encouragement for the economic development of phytoextraction and remediation programs for metal-bearing soils.

“…The latter are based on techniques such as leaching of pollutants, solidification/stabilization, size selection and pyrometallurgical processes, electrokinetical treatment, chemical oxidation/reduction of the pollutant, and excavation and removal of affected materials from the site (Chaney et al 2007;Pilon-Smits 2005;Vangronsveld et al 2009). According to Morel (2002) and Chaney et al (2010), successful phytoremediation employs three technically different operational procedures: phytostabilization (establishment of tolerant plants that protect against soil erosion and pollutant mobility), phytodegradation (in situ degradation of mining pollutants in the soil), and phytoextraction (pollutant uptake by plants through metabolic processes). Phytoremediation typically aims to establish vegetation cover on previously mined sites using hyperaccumulating species that reduce, remove, degrade, or immobilize environmental contaminants (Maiti et al 2004;Mench et al 2009;Chaney et al 2010).…”

Phytoremediation technologies potentially offer efficient and environmentally friendly solutions for clean-up of contaminated soil and have been successfully implemented in many parts of the world Ha et al 2009;Jiménez et al 2010).…”

This work explores factors supporting people perception about mine site restoration and phytoremediation. Phytoremediation is one of the most eco-friendly restoration strategy emerged since the last two decades but studies on local people perception on this restoration strategy are scarce. To fill in this gap, data were collected from mining stakeholders using a structured questionnaire administered through snowball sampling method. We used Multiple Correspondence Analysis as implemented in the software XLSTAT to visualize relationship between participants' characteristics, their view on mine site restoration and phytoremediation. Results clearly show out that people perception on mine site restoration is influenced by mining activities effects on health and region attractiveness. Phytoremediation (65.21%) was rated positively with regard to its environment potential, aesthetic and consideration for future generation followed by fillings and excavating. Restoration strategy costs have no effect on people choice and participants prefer use of shrubs as vegetation component of phytoremediation to reach their restoration objective.

“…While some of these studies have contributed greatly towards the understanding of metal uptake, non-hyperaccumulating species are not generally considered suitable for phytomining [89]. In particular, the use of food crop species to phytomine high levels of potentially toxic metals is questionable.…”

Abstract:The unique chemical and physical properties of metals mean that they are extensively utilized by industry in a huge variety of applications, including electronics, materials, industrial catalysts and chemicals. The increased consumer demand from a growing population worldwide with rising aspirations for a better life has resulted in concerns over the security of supply and accessibility of these valuable elements. As such, there is a growing need to develop alternative methods to recover them from waste repositories, current or historic, both for hazard avoidance and potentially, as a new source of metals for industry. Phytoextraction (the use of plants for the recovery of metals from waste repositories) is a green and novel technique for metal recovery, which, if done with the goal of resource supply rather than hazard mitigation, is termed "phytomining". The ability for plants to form metallic nanoparticles as a consequence of phytoextraction could make the recovered metal ideally suited for utilization in green chemical technologies, such as catalysis. This review focuses on a multidisciplinary approach to elemental sustainability and highlights important aspects of metal lifecycle analysis, metal waste sources (including mine tailings), phytoextraction and potential green chemical applications that may result from the integration of these approaches.
