leaching tests become methodology important for assessing the risk of release
of pollutants from soil into groundwater. In this present study column leaching
test were applied on soil samples taken directly in the vicinity of Kenadsa
coking plant (Algeria) in order to evaluate the mobility of copper and their
potential environmental risks. These samples have been lixiviated in laboratory
column in water-saturated condition at room temperature. All leachates have
been collected by fraction and analyzed from copper and dissolved organic
carbon. The percentages leached in column with water are very low (< 1%).
The concentrations of copper in the resulting leachates do not present a
toxicological hazard. The effect of dissolved organic carbon on copper leaching
was also investigated in this study; the results of column leaching showed that
the mobility of copper in these contaminated soil samples is associated with
the mobility of dissolved organic carbon.
