“…The TF was calculated to determine the relative translocation of metals from the water to the various plant components (root, stem, and leaf) (Barman et al 2000;Gupta et al 2008). TF = Concentration of As in plant tissue (root, stem, or leaf)/Concentration of As in corresponding water or root…”

“…It was reported that high concentration of Cd and Ni is accumulated by Sedum alfredii and Alyssum bertolonii, respectively (Deng et al 2007;Kramer 2010). The ratio of metals between soil and plants parts should be more than one for phytoremediating species (Barman et al 2000). The roots of Indian mustard are effective in removal of Cd, Cr, Cu, Ni, Pb and Zn (Prasad and Freitas 2003).…”

The issue of heavy metal pollution is very much concerned because of their toxicity for plant, animal and human beings and their lack of biodegradability. Excess concentrations of heavy metals have adverse effects on plant metabolic activities hence affect the food production, quantitatively and qualitatively. Heavy metal when reaches human tissues through various absorption pathways such as direct ingestion, dermal contact, diet through the soil-food chain, inhalation and oral intake may seriously affect their health. Therefore, several management practices are being applied to minimize metal toxicity by attenuating the availability of metal to the plants. Some of the traditional methods are either extremely costly or they are simply applied to isolate contaminated site. The biology-based technology like use of hypermetal accumulator plants occurring naturally or created by transgenic technology, in recent years draws great attention to remediate heavy metal contamination. Recently, applications of nanoparticle for metal remediation are also attracting great research interest due to their exceptional adsorption and mechanical properties and unique electrical property, highly chemical stability, and large specific surface area. Thus, the present review deals with different management approaches to reduce level of metal contamination in soil and finally to the food chain.

“…Cyanobacteria, a group of prokaryotic, photosynthetic nitrogen fixers are present in every ecological niche and therefore, exposed to the toxic effects of the metals. The effects of a few metals have been studied with respect to growth, nitrogenase activity and carbon fixation, (Ting et al1990;Cano et al 1993;Gambrell, 1994;Blackwell et al 1995;Chuan and Liu, 1996;James, 1996;Bohme, 1998;Kimbrough et al 1999;Zaccaro et al 1999;Barman et al 2000;Kisku et al 2000;Kotas and Stasicka, 2000;Suresh Babu et al 2000;Armienta et al 2001;Epniewska and Bucior, 2001;Suresh Babu et al 2001). What has not been attempted is the study of naturally immobilized cyanobacteria such as Aulosira fertilissima, in ameliorating toxicity using similar immobilized conditions in the laboratory.…”

The ubiquity of heavy metals in the biosphere results in the introduction of high amounts of toxic metals into the food chain from various sources. In the present study, one of the strongest nitrogen fixing cyanobacterium of the rice fields, Aulosira fertilissima, was subjected to nickel and chromium stress and the ameliorating effect of immobilization was investigated. Cell immobilization could protect the organism's growth against the toxicity of both heavy metals at LC 50 as compared to lethal concentrations. The nitrate reductase activity in free cells treated with the metals was substantially inhibited but immobilized cells treated with 0.1 ppm nickel was not affected by the metal treatment. Cell immobilization also resulted in a significant protection against sublethal concentration of chromium but to a lesser degree than it did with sub-lethal levels of nickel. Control immobilized cells also had higher Nitrogenase activity than control free cells. Nickel and chromium addition markedly decreased the enzyme activity in free cells but immobilized cells exposed to sublethal concentrations of both metals could overcome this decrease. Glutamine synthetase showed similar response under immobilized conditions compared to free cells with both metals. The addition of algal filtrate in 3:1 ratio further increased the nitrogenase activity compared with immobilized cells treated with sublethal doses of both metals. Immobilization facilitated higher uptake of nickel as compared to chromium. The observations of the present study clearly demonstrate the protective effect of immobilization on Aulosira fertilissima against Nickel and chromium toxicity. Rice field ecosystem thus possess a bidirectional natural metal ameliorating system where Aulosira mats act as a naturally immobilized system and the decay of Aulosira along with other cyanobacteria act as natural chelators protecting the rice plants from deleterious effects of the heavy metals. Most importantly is that the immobilization process protects the cyanobacterial nitrogen fixing process allowing it to maintain nitrogen economy of the fields in spite of the presence of heavy metals.Heavy metals are ubiquitous in the biosphere where they
