“…Climate changes increases the inten- sity of land degradation. Therefore, utilization of contaminated environment (terrestrial and aquatic) following the principles of phytoremediation for biofuel production would be one of the sustainable options (Núñez-López et al 2008). Although this strategy has immense scope and limitations (Tables 7.3 and 7.4) considerable progress and successful demonstration projects have provided convincing evidence for environmental moderation, cleanup and co-generation of revenue.…”

Environmental decontamination is an integral part of sustainable development. In recent years there has been growing interest in using plants for decontamination. On the other hand, water, soil and air are increasingly contaminated. Large amounts of toxic waste have been dispersed in thousands of contaminated sites spread all over the globe. These pollutants belong to two main classes: inorganic and organic. The challenge is to develop innovative and costeffective solutions to decontaminate polluted environment. Phytoremediation is emerging as an invaluable tool for environmental cleanup. Various strategies are being applied to reduce the accumulation of toxic metals in plants. Cultivation of edible crops in contaminated soils is a subject of human health concern if the contaminant concentration in the edible parts of crops plant exceed the permissible level. In such cases non-food crop production viz. value chain and value additions appears profitable. In this review: (1) the contamination due to industrial effluents in peri urban region of greater Hyderabad, and (2) the strategies to use contaminated soil and water for raising phytoremediation crops, and generation of value products. Crops and products include medicinal and aromatic plants, ornamental plants, biofuels, tree crops, fiber crops, dyes, and plants for carbon sequestration.

“…Bioaccumulation of lead by different plants is reported in the literature. Nunez-Lopez (2008) found that Salivinia minima became a hazardous waste after accumulating Pb(II). In another study, Haque et al (2008) found desert broom as a potential hyperaccumulator of Pb.…”

This study focused on a 75-d microplot experiment to access lead (Pb) entrance into the terrestrial ecosystem using Morus alba (mulberry) and Bombyx mori (silkworm) as pollution indicator sources. The Pb(II) mobility in different systems was in the following order: synthetic effluents > soil > plant > larva > larva-fecal. The Pb(II) mobility from an inorganic source to different life forms was found to be highly dependent on soil pH and the concentration of Pb in synthetic effluents. At lower concentrations, Pb was less lethal to B. mori larvae. Fifth instars of B. mori were found to be more tolerant to toxicity caused by Pb compared with lower instars. M. alba was not a hyperaccumulator plant because Pb(II) concentration was <1,000 mg/kg at all soil pHs and Pb(II) concentrations in effluents. The maximum amount of Pb(II) detected in soil, mulberry leaves, silkworm larvae, and silkworm feces was 326.5 +/- 0.04, 42.78 +/- 0.02, 61.24 +/- 0.02, and 22.3 +/- 0.02 mg/kg, respectively.

“…Thus, phytoremediation, the use of plants to extract, adsorb, or detoxify pollutants, has been intensively studied due to its effectiveness, non-intrusive and inexpensiveness as an environmentally harmonious and socially accepted means to remediate polluted soils (Alkorta and Garbisu 2001;Garbisu et al 2002;Alkorta et al 2004;Nunez-Lopez et al 2008). Currently, several terrestrial plants have been identified as highly effective in adsorbing and accumulating various toxic trace elements (Tang et al 2001;Liao and Chang 2004).…”

This study was conducted to investigate the uptake of lead (Pb) and arsenic (As) from contaminated soil using Melastoma malabathricum L. species. The cultivated plants were exposed to As and Pb in separate soils for an observation period of 70 days. From the results of the analysis, M. malabathricum accumulated relatively high range of As concentration in its roots, up to a maximum of 2800 mg/kg. The highest accumulation of As in stems and leaves was 570 mg/kg of plant. For Pb treatment, the highest concentration (13,800 mg/kg) was accumulated in the roots of plants. The maximum accumulation in stems was 880 mg/kg while maximum accumulation in leaves was 2,200 mg/kg. Only small amounts of Pb were translocated from roots to above ground plant parts (TF < 1). However, a wider range of TF values (0.01-23) for As treated plants proved that the translocation of As from root to above ground parts was greater. However, the high capacity of roots to take up Pb and As (BF > 1) is indicative this plants is a good bioaccumulator for these metals. Therefore, phytostabilisation is the mechanism at work in M. malabathricum's uptake of Pb, while phytoextraction is the dominant mechanism with As.
