While both an increase and a decrease in pH had an effect on the explosives;. there was a larger effect from a pH-increase. During the pH 12 washing; OH- ions were consumed; indicated through a decrease in solution pH; at the same time as the solution was colored red; which may imply the degradation of TNT.
Results from the bioremediation study indicate that this technique can be applicable on explosives-contaminated soil. The concentration of explosives decreased in all three studied applications of bioremediation. Further on; the microorganisms seemed to affect the binding of lead to the soils.
