The treatments tested were combinations of four doses of citric acid (0, 1, 2 and 3 g of citric acid/kg of soil) with two doses of NPK fertilizer (0, and 1.33 g/kg of soil). The second bioreactor is capable of taking in Martian regolith and extracting enhanced iron ores from it via biological processes. In order to solve the environmental problems with heavy metals, they have to either be removed completely from the contaminated soil or to be reliably immobilized. In Vietnam, accumulation of heavy metals in soil, water and plant biomass has been widely reported.

Beneficial heavy metals at high level could upsets the soil environment that consecutively adversely influences soil fertility, plant growth and … INTRODUCTION The heavy metals are important environmental pollutants and also a cause of potential ecological risk. Total Ni phytoextracted from soils was significantly improved using both soil treatments (inorganic and organic), despite the decrease observed in soil Ni availability and shoot Ni concentrations in compost-amended soils. The higher concentration of heavy metals has been reported to retard the cell division and differentiation, reduce their elongation and effect plant growth and development (Soares et Springer-Verlag, Berlin, pp 253–272, Israr M, Sahi S, Datta R, Sarkar D (2006) Bioaccumulation and physiological effects of mercury in, Ivanov VB, Bystrova EI, Seregin IV (2003) Comparative impacts of heavy metals on root growth as related to their specificity and selectivity. The present study investigated the effect of molybdenum (Mo), Ni phytomining is a promising technology for Ni recovery from low-grade ores such as ultramafic soils. Heavy metals have adverse effects on plants. plants for environmental restoration, consists of four different technologies for the remediation of metal polluted soils, sediments or waters namely phytoextraction, phytostabilization, rhizofiltration and phytovolatilization. Several heavy metals such as lead, cadmium, copper, manganese, etc. These heavy metals affect production of maize crop and soil quality.

It involve in the production of reactive oxygen species which leads to subsequent cell death, eventually results in reduction in crop growth and yield. We hypothesized that TMs may lead to (i) leaf apoplast modifications and (ii) changes in the antioxidant machinery efficiency that facilitate plant growth under severe contamination. The purpose of this study was to investigate the affect of different heavy metals on maize growth and to asses more tolerant and more sensitive maize variety. All soil treatments greatly improved plant growth, but the highest biomass production was generally found after addition of 2.5 or 5% compost (w/w). Inhibition of growth, reduction in the transpiration, Inhibition in seed germination, fresh and dry biomass, leaf, Reduction in seed germination and biomass, Decline in growth, chlorophyll, carotenoids and proline, Decrease in seed germination and inhibition in plant growth, Inhibition of germination, root growth, and cell division, Decrease in seed germination, repressive impression in, plant growth and reduction in root and shoot length, Inhibition of germination and prolonged time required for, Decrease in root and shoot growth and biomass reduction, Chlorosis, reduction in root, stem and leaf growth. Phytoremediation is a promising technology for decontamination of polluted soil. The aim of this present study was to determine the effects of heavy metals (Cd, Cu and Zn) on plant growth, tissue concentration and examine their uptake by sunflower in soil. Moreover, reduced growth and development also will be presented in relation to low soil pH.
