“…Phytoremediation is a widely accepted environmental restoration technology that uses plants to reduce the concentrations or toxicity of contaminants in the environment. It is cost-effective and less destructive to the soil than the traditional chemical- and engineering-based soil remediation technologies. − , Despite being available for many contaminants, e.g., heavy metals and 2,4,6-trinitrotoluene, and for various environments, − ,− phytoremediation technologies for AAs have not yet been reported in the literature, to the best of our knowledge.…”

Dietary exposure to aristolochic acids (AAs) through AA-tainted wheat has long been identified as one of the main causes of Balkan endemic nephropathy (BEN), a slowly progressive renal fibrotic disease affecting numerous residents of farming villages alongside tributaries of the Danube River. Only recently though have we begun to appreciate that AAs, released from the decay of a common weed Aristolochia clematitis, are contaminating farmland soil and groundwater of endemic areas. To reduce the risk of human exposure to this class of highly potent phytotoxins, it is imperative to develop remediation methods for AA-polluted water and arable soil. In this study, we explored the potential use of some commonly used phytoremediation plants for the phytoextraction of AAs from AA-contaminated water and soil. Among the tested plants, results showed that wheatgrass is highly efficient in extracting AAs from both contaminated water and soil and metabolizing them to the less toxic aristolactams. Furthermore, both the phytoextraction and plant metabolism efficiencies increased in an acidic environment, which is typical of endemic villages, highlighting the applicability of the developed method for affected areas.

“…There are numerous studies in the literature showing different plant species with the ability to accumulate heavy metals from polluted soils. Starting with Solanum nigrum (Wei et al, 2010), Linum usitatissimum (Bjelkova et al, 2011), Pinus silvestris (Ostrowska et al, 2006), Ricinus communis (Zhi-Xin et al, 2007 to grasses (Zhang et al, 2010) and brassicacea (Palmer et al, 2001) accumulating cadmium (Cd) la Allium fistulosum, Pteris cretica (Cho et al, 2009), Ricinus communis (Zhi-Xin et al, 2007), Phragmites australis (Weis and Weis, 2004) and Amorpha fruticose (Shi et al, 2011) as lead accumulators (Pb), or Brassica Rapa (Meers et al, 2005) and Vetiveria zizanoides (Andra et al, 2009) zinc accumulators (Zn) there are numerous species whose bioremediation potential is still insufficiently known (Chirakarra et al, 2016).…”

Heavy metal pollution, manifested by the accumulation, toxicity and persistence in soil, water, air, and living organisms, is a major environmental problem that requires energetic resolution. Mining tailing areas contain metal minerals such as Cu, Zn, Pb, Cr and Cd in high concentrations that pollute the environment and pose threats to human health. Phytoremediation represents a sustainable, long-term, and relatively inexpensive strategy, thus proving to be convenient for stabilizing and improving the environment in former heavy metal-polluted mining sites. This study presents the bioremediation potential of Silphium perfoliatum L. plants, in the vegetative stages of leaf rosette formation, grown on soil polluted with heavy metals from mining dumps in Moldova-Noua, in the Western part of Romania. The bioaccumulation factor (BAF), translocation factor (TF), metal uptake (MU) and removal efficiency (RE) of Cu, Zn, Cr and Pb by S. perfoliatum plants were determined in a potted experiment in controlled environmental conditions. The reference quantities of heavy metals have been determined in the studied soil sample. The experiment followed the dynamics of the translocation and accumulation of heavy metals in the soil, in the various organs of the silphium plants, during the formation of the leaf rosette (13-18 BBCH). The determination of the amount of heavy metals in soil and plants was achieved by the method of digestion with hydrochloric and nitric acid 3/1 (v/v) quantified by atomic absorption spectroscopy (AAS). The obtained experimental results demonstrate that the substrate has a high heavy metal content being at the alert threshold for Zn (260.01 mg kg-1 in substrate compared with alert threshold 300 mg kg-1) and at intervention thresholds for other metals (Cu -234.66 mg kg-1/200 mg kg-1; 299.08 mg kg-1/300 mg kg-1 and Pb-175.18 mg kg-1/100 mg kg-1). The average concentration of the metals determined in dynamics in the dry biomass of plants varied between roots, petioles, and laminas. The root is the main accumulator for Cu and Cr (Cu – 37.32 mg kg-1 -13 BBCH to 43.89 mg kg-1-15 BBCH and 80.71 mg kg-1 – 18 BBCH; Cr – 57.43 mg kg-1 – 13 BBCH to 93.36 mg kg-1 -18 BBCH), and for Zn and Pb the lamina seems to carry the same function. Preliminary results show that Silphium perfoliatum may be a viable alternative in the bioremediation and treatment of heavy metal-contaminated area.

“…It is worth noting that Tambamroong (2002)studied the effects of EDTA to remove As (Arsenic) from contaminated soil with Taro and Elephant ear plants. Cho et al (2008) studied Pb removal from contaminated soil using EDTA with green onions used for the uptake process. This research used Colocasiaesculenta to remediate Pb contaminated water from Klity Creek, Kanchanaburi province.…”

This study investigated lead (Pb) removal using a plant called'Elephant Ear' (Colocasiaesculenta (L.) Schott) from contaminated waterat Klity Creek, located in Kanchanaburi Province, Thailand. Plants weregrown in contaminated water with lead carbonate (Pb(CO 3) 2) in a nursery. The experiment was divided into 4 sets; (1) With Pb but without EDTA, (2) With Pb and EDTA 0.01 millimole (mM) per liter (mM L −1), (3) With Pband EDTA 0.02 mM L −1 and (4) With Pb and EDTA 0.03 mM L-1. These plants were grown, maintained and harvested every 15, 30, 45, 60, 75 and 90 days. Plant samples were separated into three parts; leaf, petiole and root. They were analyzed in terms of total lead (TPb) content, including the water solution. The results showed that Pb accumulation in Elephant ear was relatively significant in all of the experiment sets (p<0.05) at 15 days. The results showed that Pb accumulation in the whole plant was highest at 90 days. This study showed that Pb absorption in plant was enhanced when the concentration of EDTA increased. Plants showed that Pb accumulation in roots > petioles > leaves were significant with 502.84, 126.19 and 91.06 mg kg −1 (p<0.05) at EDTA of 0.02 mM set, respectively. Plants exhibited signs of phytotoxicity, such as wilting and curling of their leaves, yellow color appearing in the leaf margins and the plants eventually dying. These effects could be used as an indicator for determining the presence of Pb in contaminated water and soil.
