“…Soil characteristics, climatic conditions, and WW composition regulate the mobility of metals in soil and groundwater (GW) and their bioavailability to crops grown. Dietary intake of metals assimilated in edible parts of crops and GW poses a major threat to food safety and public health (Minhas et al 2006;Lal et al 2008). Assimilation and translocation of specific metals to different plant parts depends on the physiology of individual crops (Ebbs et al 1997;Landonin 2002).…”

Farmers in developing countries irrigate crops using raw urban and industrial effluents with consequent risks from metal contamination. Therefore, soils, crops and groundwater from an effluent irrigation use site were assessed for Cd, Cr, Ni and Pb. Total and available contents of metals in soil followed the order Pb>Ni>Cr>Cd. Crops accumulated more Pb, followed by Cd, Ni and Cr. Pb exceeded the permissible limit with wastewater irrigation only, but Cd exceeded the limit even with combined irrigations of wastewater and groundwater. Among crops, sugar beet assimilated highest Cd (3.14 μg g(-1)) and Pb (6.42 μg g(-1)) concentrations. Legumes accumulated more metals than cereals. Long-term use of wastewater and its conjunctive use with groundwater led to toxic accumulations of Cd, Pb, Ni and Cr. Cd with higher availability and mobility indices and lower toxicity limit, posed the maximum risk of food-chain contamination.

“…The cultivation of edible plants on polluted lands would even if successful be under continual scrutiny because of the potential for accumulation of pollutants in edible tissues (Dziubanek et al 2015). Another approach could be to restrict cultivation to non-food crops, such as those used for floriculture, horticulture, biomass, biofuels or production of commercially important chemicals (Lal et al 2008;Jamil et al 2009). In this context, cultivating ornamental plants on contaminated lands is a logical choice as it provides economic benefits, aesthetic value and possibly also ecological services during propagation to birds, honeybees, butterflies and other species (Lal et al 2008;Ling-Zhi et al 2011).…”

Sustainable food production for a rapidly growing global population is a major challenge of this century. In order to meet the demand for food production, an additional land area of 2.7-4.9 Mha year-1 will be required for agriculture. However, one-third of arable lands are already contaminated; therefore, the use of polluted lands will have to feature highly in modern agriculture. The use of such lands comes, however, with additional challenges, and suitable agrotechnological interventions are essential for ensuring the safety and sustainability of relevant production system. There are also other issues to consider, such as cost-benefit analysis, the possible entry of pollutants into the phytoproducts, certification and marketing of such products, in order to achieve the large-scale exploitation of polluted lands. The present article addresses the sustainability challenges of crop production from polluted lands and briefly outlines the plausible strategies for using polluted lands for sustainable agricultural extensification.

“…For a country like India, phytoremediation is best suited as it requires low investment, and relies on plants' natural capability to take up metal ions from soil (Ghosh and Singh 2005). Identification/selection of plant species for phytoremediation is a continuous process and till date, many plants have been found as remediation plants but there are very few reports about the use of ornamental plants for phytoremediation purpose Lal et al 2008aLal et al , 2008bRamana et al 2008aRamana et al , 2008bRamana et al 2009). Especially, in urban areas, ornamentals can beautify the environment, and also resolve heavy metal pollution (Wang and Zhou 2005).…”

The potential of an ornamental shrub Crown of thorns (Euphorbia milli) was evaluated for remediation of soil contaminated with Cr. The plant is one of the rare succulent ornamental shrubs with a slow to moderate growth rate and is capable of blooming almost year-round. The plant could tolerate well up to 75 mg of applied Cr and beyond that there was mortality of plants. Though the plant could not be classified as a hyperaccumulator, the plant was still very efficient in translocating Cr from roots to shoots as evident from the data on uptake and translocation efficiency values. The translocation efficiency of over 80% in our study demonstrates that a large proportion of Cr has been translocated to the harvestable biomass of the plant and therefore, this plant could be effectively recommended for the remediation of soils contaminated with low to medium level of contamination i.e., up to 50 mg/kg soil.
