Remediation of heavy metals in soil treated with industrial sludge using rock phosphate [electronic resource].

Includes references.

The present study was conducted to test the ability of rock phosphate. applied as a single amendment, to remediate heavy metals such as Fe. Mn, Zn. Cu, Co, Pb, Ni and Cd phytotoxicity in industrial sludge-polluted soils. A factorial field experiment was carried out using a virgin sandy soil at the Experimental Station of the Egyptian Atomic Energy Authority, Egypt. Industrial sludge and rock phosphate were added at the rates of 0, 20, 40 and 80 tonlfed and 0, 100, 200 and 400 kg/fed, respectively. Sorghum (Sorghum vulgare) was used as an indicator plant and after 70-day growth period. sorghum shoots and roots were taken. oven-dried at 70°C and dry matter yield was recorded. Samples of sorghum shoots and roots were dry-ashed for determining of tested heavy metals content.
