The Influence of Industrial Residues of Phosphate Fertilizers Complexes on Content of Phosphor, Cadmium and Lead in Soil and Water

Abstract

The study was carried out in Al-Qaim region near by the factory of fertilizer about 420 km west of Baghdad. Samples of soils were taken by depths of (0-0.20), (0.20-0.40) and (0.40-0.60) m with three directions (N north, S south, E east) according to the direction of annuity wind. Soil samples were taken at three distances from the factory (500, 1000, and1500) m. Samples of water were taken from three sources; wells, acidic and alkaline water from the factory. The aim of this paper was to study the influence of residue of phosphate fertilizer factory in content of Phosphor, Cadmium and Lead of soil and water. The results showed that the highest values of available phosphorus were 956.80 and 528.46 mg l-1 for distances 1500 and 1000 m, at depths of 0.4-0.6 m in the N1 directions as well as for N1 and S1 directions at the depth of 0-0.2. The highest total cadmium content was 4 mg l-1 for 500 m distance with the N1 direction at depth of 0-0.2m respectively. available cadmium was found in small quantity and consider negligible. The available lead was 83 and 0.45 mg l-1, for 1000 and 500 m distances in the direction of N1 for the depths of 0-0.2 and 0.2-0.4m respectively.
