Nano zero-valent iron (nZVI) is currently investigated as a stabilising amendment for contaminated soils. The effects of pH and time on the behaviour of Pb-Zn and As-contaminated soils treated with nZVI including the solid phase investigations have been recently published in Journal of Environmental Management.
