“…Ricinus communis, found as a potential hyperaccumulator of Cr in the present study, is also known to accumulate other HMs like Ba [48,49], As [50] and Ni [51,52]. Even though the shoot accumulation of Cr is considered as a rare phenomenon, the high translocation rate in the present study may prevent the precipitation of Cr from roots and vascular systems, resulting in hyperaccumulation of Cr in the aerial parts [53].…”

Herbal preparations used to treat human ailments globally can be contaminated with various heavy metals (HMs) originating from the raw materials or from the manufacturing processes. Therefore, we assessed 22 medicinal plants growing naturally on tannery pollutant contaminated (Site-C) and non-contaminated (Site-NC) sites for their ability to accumulate chromium (Cr). The Cr contents in soil and various plant parts were estimated using an atomic absorption spectrophotometer. Translocation and bioconcentration factors were calculated. The soil at Site-C had 27-fold higher concentration of total Cr than at Site-NC. Chromium accumulation is reported for the first time in 50 % of the medicinal plants examined and varied significantly among the sites. Shoots of Ricinus communis and Amaranthus viridis had maximum concentrations of Cr at Site-C, whereas in Site-NC, none of the plants had Cr accumulation >30 ppm. Ricinus communis, Amaranthus viridis, and Amaranthus spinosus had translocation factor (TF) greater than the one in the Site-C and Lantana camara had TF >1 in Site-NC. The bioconcentration factor (BCF) was >1 only for Ricinus communis at both the sites. The majority of the medicinal plants at Site-NC had Cr content exceeding the permissible limit of 2 ppm suggested for herbal raw material. The results of the study clearly emphasize the need for screening plants of therapeutic value for the presence of HMs even when collected from non-contaminated soils. Moreover, proportional allocation of Cr in different plant parts provided an insight on the safety of these parts when specifically used in herbal preparations.

“…These include recycling of nutrients, maintenance of soil structure, detoxification of pollutants, and control of plant pests and promoting plant growth and plant health (60)(61)(62). Castor bean is reported as a suitable candidate for phytostabilization of co-contaminated sites (organics and inorganics) (10,(63)(64)(65), heavy metals (11,(66)(67)(68)(69) and polycyclic aromatic hydrocarbons (PAHs).…”

Phytoremediation is a plant based environmental cleanup technology to contain (rendering less toxic), sequester and degrade contaminated susbtrates. As can be seen from data metrics, it is gaining cosiderable importance globally. Phytoremediation approach is being applied for cleanup of inorganic (potentially toxic metals), organic (persistent, emergent, poly-acromatic hydrocarbons and crude oil etc.) and co-contaminated (mixture of inorganic and organic) and/or polluted sites globally. Recently new approaches of utilizing abundantly available natural organic amendments have yielded significant results. Ricinus communis L. (Castor bean) is an important multipurpose crop viz., Agricultural, Energy, Environmental and Industrial crop. The current status of knowledge is abundant but scattered which need to be exploited for sustainable development. This review collates and evaluates all the scattered information and provides a critical view on the possible options for exploiting its potential as follows: 1. Origin and distribution, 2. Lead toxicity bioassays, 3. Progress in arbuscular mycorrhizal fungi-assisted phytoremediation, 4. Promising bioenergy crop that can be linked to pytoremediation, 5. A renewable source for many bioproducts with rich chemical diversity, 6. It is a good biomonitor and bioindicator of atmospheric pollution in urban areas, 7. Enhanced chelate aided remediation, 8. Its rhizospheric processes accelerate natural attenuation, 9. It is suitable for remediation of crude oil contaminated soil, 10. It is an ideal candidate for aided phytostabilization, 11. Castor bean is a wizard for phytoremediation and 12. Its use in combined phytoextraction and ecocatalysis. Further, the knowledge gaps and scope for future research on sustainable co-generation of value chain and value addition biobased products for sustainable circular economy and environmental security are described in this paper.

“…The studies on tolerance and phytoremediation of Ni by R. communis in different agroclimatic conditions are, however, very rare. Malarkodi, Krishnasamy, and Chitdeshwari (2008), Rajkumar and Freitas (2008), and Ma, Rajkumar, and Freitas (2011) have reported that addition of organic manures or plant growth-promoting rhizobacteria (PGPRs) reduces the toxicity of the metal for plants and facilitate its mobilization from soil. Adhikari and Kumar (2012) have recently reported that roots of Ni-treated plants show decreased cells in the cortex region and Ni is present in soil as residual > FeMn oxide > carbonate > organic > exchangeable > water-soluble forms.…”

“…Different authors have shown different levels of the metal tolerance and bioaccumulation of Ni in Indian mustard (B. juncea), which may be due to genetic and agroclimatic variations (Zaidi et al 2006;Alam et al 2007;Ali et al 2008;Sharma et al 2008). R. communis has also been reported to possess good tolerance to Ni and has shown significant bioaccumulation of Ni in certain studies (Malarkodi, Krishnasamy, and Chitdeshwari 2008;Rajkumar and Freitas 2008;Ma, Rajkumar, and Freitas 2011;Adhikari and Kumar 2012). The protein content in the leaves was found decreased in both the species due to Ni application.…”

The effect of increasing level of nickel (Ni) in soil was studied on biomass production, antioxidants, and Ni bioaccumulation and its translocation in castor bean (Ricinus communis) as well as Indian mustard (Brassica juncea) in similar agroclimatic conditions. The plants were exposed to 25, 50, 75, 100, and 150 mg Ni kg ¡1 soil for up to 60 days. It was found that R. communis produced higher biomass during the same period at all the contamination levels than B. juncea, and reduction in fresh and dry weights due to the metal contamination in soil was significantly lower in R. communis than in B. juncea. Proline and malondialdehyde in the leaves increased with increase in Ni level in both the species, whereas soluble protein content was found decreased. A correlation between the protein and MDA contents in the leaves and Ni contamination levels revealed that higher r 2 values for protein and MDA were found in case of B. juncea, which indicates more toxic effects of the metal in this species. R. communis was found to have enhanced proline accumulation (higher correlation value, r 2 ) at different Ni contamination levels. The bioaccumulation of Ni was higher in B. juncea on the basis of the per unit biomass; however, the total metal accumulation per plant was much higher in R. communis than in B. juncea during the same growing periods. The translocation of Ni from roots to shoots was higher in B. juncea at all Ni concentrations. R. communis appeared more tolerant and capable to clean more Ni from the contaminated soil in a given time and also in one crop cycle.
