| Abstract | ||
| Lead is one of the toxic elements for environment, human, animal, and plant For this reason , ten locations were selected in Basrah governorate with two depths (0-5 and 5-30 cm) ,and near –far from source of pollution to from fourteen soil samples .Soil samples were collected during Dec. 2007 to Jan. 2008. Chemical and physical Properties of soil Samples were determined. Different forms of lead in soils were extracted and determined including total, soluble and available lead which extracted by DTPA solution, 1M NaOAC and 1M NH4OAC. Results indicated that total lead concentration in studied soils were in the range of (209.04 to 4326.92mg Kg-1 soil) with the mean value of (1147.09mg Kg-1soil),soluble lead concentration was between (0.17 to 8.13mg L-1) with the mean value of 0,17 mg L-1, and these values represent (0.17%) of total lead concentration. Chemical extracts were differed in their extraction abilities of available lead , as follower in the order : DTPA solution>1M NaOAC >1M NH4OAC the 0-5cm,and sites near pollution sources were surpassed 5-30 cm and for pollution sources in total, soluble and available lead. | ||
