Changes in chemical forms of lead and its availability to corn and sunflower in inorganic salt and Pb enriched biosolids treated soil Amir Hossein Baghaie E mail address ambaghaie@yahoo com 1 December 2010 Department of Soil Science Isfahan University of Technology Isfahan 84156 83111 Iran Supervisor Amir Hossein Khoshgoftarmanesh E mail address amirhkhosh@cc iut ac ir Supervisor Majid Afyuni E mail address Afyuni@cc iut ac ir Advisor Hossein Shariatmadari Advisor Hossein Khademi Department Graduate Program Coordinator Farshid Norbakhsh Department of Soil Science College of Agriculture Isfahan University of Technology Isfahan Iran Abstract The purpose of this study was to determine lead Pb fractionation in a sandy loam soil amended with enriched 600 mg Pb kg 1 biosolids and cow manure before and after cultivation of sunflower Helianthus annuus L and corn Zea mays L Single cross 704 In the salt treatment the Pb bounded to the oxide fraction was higher 8 7 and the carbonate fraction was lower 12 in the rhizosphere of sunflower compared to the rhizosphere of corn In soils treated with biosolids and inorganic Pb salt corn accumulated greater amounts of Pb in its roots compared to the sunflower whereas both crops had similar root Pb concentration in the manure amended soil A high correlation 92 was found between the Pb uptake by the crops grown in the soils treated with the biosolids and cow manure to the metal concentration in the soil inorganic fractions The phototoxic effects of Pb were clearly observed on the sunflower grown in the Pb salt treated soil while no such effect was found for the plants grown in the soils treated with the sludge and manure Keywords Sunflower corn sequential extraction lead
