“…Lead is another metal of great concern as it can cause brain, liver and kidney damage in children and nerve damage in adults, while long term exposure to cadmium can cause kidney failure, liver, bone and blood damage [5]. Heavy metals cause oxidative stress in plants [22][23][24][25]. Metal stress was reported to affect photosynthesis, chlorophyll fluorescence and stomatal resistance [26].…”

Abstract:The gold mining plant of Oman was studied to assess the contribution of gold mining on the degree of heavy metals into different environmental media. Samples were collected from the gold mining plant area in tailings, stream waters, soils and crop plants. The collected samples were analyzed for 13 heavy metals including vanadium (V), chromium (Cr), manganese (Mn), nickel (Ni), copper (Cu), cadmium (Cd), cobalt (Co), lead (Pb), zinc (Zn), aluminium (Al), strontium (Sr), iron (Fe) and barium (Ba). The water in the acid evaporation pond showed a high concentration of Fe as well as residual quantities of Zn, V, and Al, whereas water from the citizens well showed concentrations of Al above those of Omani and WHO standards. The desert plant species growing closed to the gold pit indicated high concentrations of heavy metals (Mn, Al, Ni, Fe, Cr, and V), while the similar plant species used as a control indicated lesser concentrations of all heavy metals. The surface water (blue) indicated very high concentrations of copper and significant concentrations of Mn, Ni, Al, Fe, Zn, lead, Co and Cd. The results revealed that some of the toxic metals absorbed by plants indicated significant metal immobilization.

“…Some plant species can grow in these severe conditions. Excessive concentration of heavy metals in plants can cause oxidative stress and stomatal resistance (Fayiga et al, 2004;Shah et al, 2009). It can also affect photosynthesis and chlorophyll florescence processes (Monni et al, 2001).…”

ABSTRACT:The degree of contamination by heavy metals (arsenic, copper, lead, tin and zinc) in soil and transfer to plants has been studied. Specimens of plant species from five locations in an area of 10 x 10 m were sampled with their corresponding soils. Thirty six plant species including two shallow water aquatic plants were identified. Soil and plant specimens were analyzed by using inductively coupled plasma optical emission spectrometry. It was found that metal concentration in soil was highly variable while concentration of metals in plants directly depends on the concentration of metals it was rooted. Roots showed highest metal concentration followed by leaves, shoots and flowers. Bioconcentraion factor and translocation factor were calculated, representing Cyperus rotundus L. as a potential tin-hyperaccumulator plant, previously not reported in literature. Plant Species Imperata cylindrica, Lycopodium cernuum, Melastoma malabathricum, Mimosa pudica Linn, Nelumbo nucifera, Phragmites australis L., Pteris vittata L. and Salvinia molesta, were metal accumulator while Acacia podalyriaefolia G. Don, Bulb Vanisium, Dillenia reticulate King, Eugenia reinwardtiana, Evodia roxburghiania Hk. f. clarke, Gleichenia linearis, Grewia erythrocarpa Ridl., Manihot esculenta Crantz, Paspalum conjugatum Berguis, Passiflora suberosa, Saccharum officinarum, Stenochlaena palustris (Burm.) Bedd. and Vitis trifolia Linn. were tolerated plant species. All other studied plants were excluders. Identified plant species could be useful for revegetation and erosion control in metals contaminated ex-mining sites. Morphological changes such as reduction in size, change in color and deshaping have also been observed in plant species with high metal values.

“…are not necessary for plant growth, however they are passionately taken up and accumulated by plants up to toxic levels [1][2][3][4] . In public attitude, phytoremediation technology is more favorable due to its potential for cleaning up environment and the overall aesthetic perfection of the contaminated sites [5][6][7] . Plants are ideal agents for soil and water remediation because of their unique genetic, biochemical and physiological features [8][9][10][11][12] .…”

In order to investigate the effect of adding black tea leaves residue to contaminated soil due to enhance accumulating potential of heavy metals by sorghum spice an experiment was carried out. The contaminated soil by heavy metals mixed by remaining infusion of black tea ( 8:1). Sorghum Bicolor and halepence were cultivated into the research soil study. Results showed that S. Halepence transition factors for all heavy metals in treated soil were higher than one and as expected the heavy metal uptake rate by S. Bicolor plant is significantly affected by tea leaves added to soil of plant cultivated .
