Abstract
Some of the World War II battles took place on the land of Northern
west coast of Egypt. Among the activities that took place is burying
anti personal and anti tank mines (22 million within an area of
660,000 feddans). When war end up with victory of allied forces
these mines were forgotten and Egyptians suffer a lot from them in
many aspects.
1- Such mines caused many casualties (deaths and handicapped).
2- Depriving from exploiting the natural economic resources within
an area of 700,000 feddans to be used in development activities
(agriculture, mining and tourism).
Egypt took the lead to remove these mines using the technical
experience of Egyptian armed forces and financial support of some
European countries (USA, England, and Germany).
Some of 2.976 million land mines were removed until 2010.Which
enables authorities to exploit 89700 feddans. As bombing activities
leave some TNT residues in soil a question is raised, Is this land can
be safely used? and to what extent such material is degraded
naturally? and what is the time needed for such degradation? So, the
study aims at:
1- Determining the concentration of TNT residues after bombing.
2- The behavior of TNT residues after 5 months.
3-The usability of soil for agriculture purposes after degradation.
To do so, two bombing were carried out at different location in El
Alamin- Matruoh governorate. The first used 6 kg TNT was bombed
while in the other 10 kg was bombed .In the two bombings the hole
and depth of bombing is measured. Then, soil samples were collected
before bombing at different depths 0-4, 4-20, and 20-47 cm to
56
determine physical and chemical properties. After each bombing soil
samples and collected at the mentioned depths and divided in two
part. The first was kept in refrigerator to be zero time, while the other
is left in ambient conditions to follow degradation process.
After bombing (6)kg it can be seen that while degradation reached
93% and 91% for the depth 0-4 and 4-20 respectively it decreased to
63.5% at the depth 20-47cm . Also, after bombing 10kg it can be seen
that while degradation reached 78.19% and 75.99% for the depth 0-4
and 4-20 respectively it decreased to 67.39% at the depth 20-45cm.
