Abstract:
Jebel Toria is a hell south of Omdurman, where different types of heavy
machines are moving. The machine are moving rocks and crushing them to
smaller sizes. Some rocks and stones are used in building foundation. Some
rocks are crushed to be used in roads manufacturing.
Samples of soils were taken at (20cm) depth. Four samples were collected at
distance of 100 meter far from Jebel toria in the four principle directions. A fifth
sample was taken from east north direction. The sixth sample was a reference
sample. It was collected from 1000 meter far from heavy machines moving
area.
The aim of this study was determined if the soil around the hell are polluted by
some metallic minerals or not.
The sequence extraction method (BCR) was used to extract the concerned
minerals from the six soil samples.
Some physicochemical properties has been studied. These include ash content,
moisture contents and concentration of Iron, Copper, Nickel and chromium.
The analysis showed that the fraction number (4) of the extraction has the
highest value of Iron, Copper, Nickel and chromium concentration compared to
the other three fractions.
