“…Biological processes including plant-microbe interaction and rhizospheric processes, plant uptake, translocation mechanisms, tolerance mechanisms and plant chelation significantly affect the efficiency of phytoremediation (Pilon-Smits 2005). The uptake of metals from the soil depends on different factors such as their soluble content in it, soil pH, plant growth stages frequency of harvesting types of species, fertilizers and soil (Sharma et al 2006;Ismail et al 2005). The application of phytoremediation for the control of environmental pollution has several limitations that require further intensive research on plants and sitespecific soil conditions.…”

The ability of heavy metals bioaccumulation to cause toxicity in biological systems-human, animals, microorganisms and plants-is an important issue for environmental health and safety. Recent biotechnological approaches for bioremediation include biomineralization (mineral synthesis by living organisms or biomaterials), biosorption (dead microbial and renewable agricultural biomass), phytostabilization (immobilization in plant roots), hyperaccumulation (exceptional metal concentration in plant shoots), dendroremediation (growing trees in polluted soils), biostimulation (stimulating living microbial population), rhizoremediation (plant and microbe), mycoremediation (stimulating living fungi/mycelial ultrafiltration), cyanoremediation (stimulating algal mass for remediation) and genoremediation (stimulating gene for remediation process). The adequate restoration of the environment requires cooperation, integration and assimilation of such biotechnological advances along with traditional and ethical wisdom to unravel the mystery of nature in the emerging field of bioremediation. This review highlights better understanding of the problems associated with the toxicity of heavy metals to the contaminated ecosystems and their viable, sustainable and eco-friendly bioremediation technologies, especially the mechanisms of phytoremediation of heavy metals along with some case studies in India and abroad. However, the challenges (biosafety assessment and genetic pollution) involved in adopting the new initiatives for cleaning-up the heavy metals-contaminated ecosystems from both ecological and greener point of view must not be ignored.

“…As plants acquire necessary nutrients, such as nitrogen, phosphorus and potassium, they also accumulate metals such as lead, cadmium (Ismail et al 2005). Heavy metals are not biodegradable and can accumulate in human organs, producing progressive toxicity.…”

The main purpose of this research was to determine the levels of heavy metals in tomato, potato and lettuce, grown in agricultural soils of different soil orders (Alfisols, Endisols and Vertisols), located at Central Greece. Soil samples were analysed for available forms (after extraction with DTPA) and for total concentrations (after digestion with Aqua Regia) of metals. Zn, Cu, Cr and Ni were the common metals detected in the vegetables studied. Pb and Cd concentrations were low and in some cases not detectable. Significant correlations among metals concentrations and soil physicochemical parameters were obtained and discussed. The pH value and the percentage of clay content were found to determine the solubility of metals in the soil and their availability for uptake by plants.

“…The effect of irrigation with effluents is also studied in many crops to observe the concentration of accumulated metals to which human beings are exposed [5,35,36]. Heavy metals are easily accumulated in the edible parts of leafy vegetables, as compared to grain or fruit crops [4,7].…”

“…The researches indicated paper mill industries not only led to accumulation of toxic elements in soil environment, but also increased the risk of accumulation in crop plants [20,35,37]. The present study was conducted with an aim to study the distribution and accumulation of heavy metals in soil and potential of the commonly grown leafy vegetable Trigonella foenumgraecum L. (Fenugreek) after fertigation with paper mill effluent.…”

The aim of the study was to investigate distribution, enrichment and accumulation of heavy metals in soil and Trigonella foenum-graecum (var. Pusa Early Bunching) after fertigation with paper mill effluent. Doses of paper mill effluent viz. 5%, 10%, 25%, 50%, 75% and 100% were used for fertigation of T. foenum-graecum along with bore well water (control). The results revealed that paper mill effluent had significant (P < 0.05) effect on EC, pH, OC, Na, Cd, Cr, Cu, Mn and Zn of the soil in both seasons. Insignificant (P > 0.05) changes in WHC and bulk density of the soil were observed after irrigation with paper mill effluent. The agronomical performance of T. foenum-graecum was increased from 5% to 25% concentration and decreased from 50% to 100% concentration of paper mill effluent as compared to control in both seasons. The heavy metals concentration was increased in T. foenum-graecum from 5% to 100% concentrations of paper mill effluent in both seasons. Biochemical components like crude proteins, crude fiber and crude carbohydrates were found maximum with 25% paper mill effluent in both seasons. The enrichment factor (Ef) of various heavy metals was in order of Cd > Mn > Cr > Cu > Zn > Fe for soil and Mn > Cu > Cr > Cd > Zn > Fe for T. foenum-graecum plants after fertigation with paper mill effluent. Therefore, paper mill effluent can be used as a biofertigant after appropriate dilution to improve yield of T. foenumgraecum.
