Abstract |
: |
Two experiments were carried out in this research. First experiment: Study of the impact of Al- lith carbon fly ash landfill on the ambient soil pollution through collection of soil samples every three months for a year ( Autumn – Winter – Spring – Summer) and analysis of these samples for heavy and toxic metal (vanadium – zinc – nickel – chromium – lead), and consequently evaluation of this landfill environment and how it can affect the surrounding soil.
Second Experiment: Study of the effect of different rate of the fly ash (Zero – 0.02 – 0.04- 0.06 wt %) on the yield and yield components of 5 crops (barley – canola – cobbage - squash, okra )
The main results were:
First Experiment (1): Heavy and Toxic metal soil concentrations decreased with increase in distance from the landfill where they were higher at 250 and decreased at 500 and 1000 m respectively.
(2) There were difference in metal concentration with direction of sample from the landfill, and the highest concentration was in the south decreasing eastward, westward and northward respectively.
(3) level of Ni ad V were higher than the permissible level and can cause toxicity to plant, animal and human beings.
Second Experiment: (Field study):
(1) Reduction in yield and yield components in barley, canola, cabbage - squash, okra , with increase in fly ash rates application to the soil.
(2) Increase of the plant part content of (Zn, Pb, Ni, Cr, and V ) with increase of the rates of fly ash application to the soil from zero to 0.06%. The highest level of these metals was in the root, decreasing respectively in the stem, the leaf and in the fruit of all crops.
(3) Concentration of Cr, Ni, and V in the root, stem and leaf reached toxic level, where Pb and Zn were below toxicity in all crops. |
