3. 1- Objectives of the study
The study aims to:
assess heavy metal pollution in soils in the adjoining area to the phosphate fertilizer plant and suggesting suitable solution for the present environmental impacts.

4. -Conducting researches on heavy metal pollution in soil is one of important issues worldwide.
-Heavy metal do not go degradation, so they last many years in soil.
-They affect microbial activity in soils, enzymes, prevent nutrients to be absorbed through plant rihzosphere zone.
They may leach from soil to deteriorate groundwater depending on soil layers.
they deplete soil quality by forming complexes with organic matter in soils.

5. Study area:

6. The phosphate fertilizer plant is located 9 km north of Assiut city with GPS ( N , E) built on about 20 sedans. The investigated area is lying downwind of the plant and much amounts of gases, fumes , vapours and particulates bearing heavy metals are deposited into soils of this area. The plant established 1978, till now there is no studies conducted to assess HMs and soil quality although impacts on plant , death of goats and sheep and visual signs of impaired environment.

23. Figure 8: Concentration of heavy metals compared with control and guideline values

24. Conclusion
The phosphate fertilizer plant brings about serious heavy metal pollution problem. The soil is seriously polluted by heavy metals. The contents of Cd, Pb, Zn, Hg and As in soil reached a dangerous level where their concentration values surpassed those of the reference sample by significant values [10]. Cd and As are not detected in control sample and this refers that almost concentrations of the two elements do harm to the environment.
