Abstract |
|
|
| Fertilizers, indispensable as they may be nevertheless materials that also clearly cause serious environmental contamination, notably in agricultural soils. The dire necessity for increased food production has been more marked than ever before. Thirty soil and fourteen fertilizer samples were collected from three governorates (El Sharqia, El Giza, and El Fayoum), studied mineralogically, and analyzed by X-ray fluorescence technique for heavy and trace elements determination. The fluctuation of heavy metals and trace elements in the studied soils could be related to the use of industrial and organic fertilizers, in addition to anthropogenic effects. All the studied hazard parameters on different types of soils indicate a greater degree of contamination in the El Sharqia region in comparison with EL Fayoum and El Giza for higher nickel and zirconium contents. The ecological risk assessment of fertilizers exhibits that both types of fertilizers pose a moderate ecological risk, with Superphosphate samples showing slightly higher risk due to the presence of V and Zn. |
