Heavy metal contamination of soil may pose risked and hazards to humans and animals and the ecosystem through direct ingestion or contact with contaminated soil. Soil contamination by toxic metals is one of the serious ecological problems all over the world. Basic sources of this contamination are the metal smelting industry, residues from metalliferous mining, combustion of fossil fuel and waste incineration, as well as some pesticides and fertilizers used in agriculture. This in addition to soils that are naturally rich in heavy metals. The main metals Cd, Pb, Ni, Zn, Cu, and the metalloid As. When plants accumulate metals, these metals can be ingested by animals, thus creating the potential for toxic effect at higher tropical levels. These widespread and persistent environmental pollutions have a high toxicity potential for reproductive and developing tissue and can induce teratogenicity in mammals. For remediation of Zn and Ni with the help of Hardeum Vulgare. Barley was grown in artificially contaminated soil. Soil is treated with different amendment in different percentage. Some metals also treated in soil (mg/kg) in the form of hydrate, after harvesting crop, plant were cut and dry at room temperature. Dry plant samples convert in to fine powdered from and react with di-acid and make a 100 ml distal water sample. The observe concentration of Zn and Ni are (3.34mg-5.85mg) and (3.72mg-6.47mg) respectively in species of Barley.
