Determination of the Content of Heavy Metals in Pyrite Contaminated Soil and Plants
نویسندگان
چکیده
Determination of a pyrite contaminated soil texture, content of heavy metals in the soil and soil pH, was the aim in the investigation. Acidification of damaged soil was corrected by calcium carbonate. Mineral nutrients and organic matter (NPK, dung, earthworm cast, straw and coal dust) were added to damaged soil. Afterwards, the soil was used for oat production. Determination of total heavy metal contents (Cu, Pb, Zn, Fe) in soil was performed by atomic absorption spectrofotometry. Plant material (stems, seeds ) was analysed, too. Total concentration of the heavy metals in the plant material were greater than in crop obtained in unaffected soil.

Performance of purslane (Portulaca oleracea) in nickel and cadmium contaminated soil as a heavy metals-removing crop
Specific plants can remove heavy metals from the soil and contribute to pollution remediation in cropping systems. Determining the level of highest heavy metals that a super-accumulator crop can withstand without reducing its yield is important for management. The objective of this study was to investigate the heavy metal-removing capacity of purslane by studying different stress criteria and b...
متن کاملPhytoremediation potential of heavy metals by two native pasture plants (Eucalyptus grandis and ailanthus altissima) assisted with AMF and fibrous minerals in contaminated mining regions
The current study assesses the effect of fibrous clay minerals’ amendments and arbuscular mycorrhiza incubation on heavy metal uptake and translocation in Eucalyptus grandis and Ailanthus altissima plants. For doing so, Eucalyptus and ailanthus trees have been grown in a soil sample, contaminated with heavy metal iron ore mining and collected from southern Iran. The area under study is arid, wi...

متن کاملPhytoremediation of soils polluted by heavy metals using Vetiver grass and Tall Fescue
Phytoremediation is a biological method to improve soils contaminated with heavy metals. The objective of the present research was to study the capability of Vetiver grass and Tall Fescue in refining and reducing pollution of Cd, Cu and Zn from contaminated soils. The research was implemented in greenhouse during two separate tests (Vetiver grass and Tall Fescue) in a completely randomized desi...

Soil and sediments of the estuaries and wetlands in Northwest of Persian Gulf are recently polluted with different heavy metals because of municipal and industrial wastewaters. Therefore an urgent soil cleaning up and remediation program is vital in this region. Consequently, this study was initiated to screen two plant species (Festuca arundinacea and Cynodon dactylon) for hyperaccumulation of...
