Abstract

Recently, the injection of cement stabilizer is used as one of ways to improve soft sea-bottom. However, this method makes an argument with heavy metals subject to emerge to the seawater from the cement stabilizer. To investigate the amount of dissolved heavy metals(Cr, Cr6+, Cd, Co, Cu, Ni, Pb and Zn) field measurements were carried out in Ocheon harbor of the Chunsoo Bay. The analysis shows that the highest concentrations of dissolved heavy metals were found in the surface seawater of the injection point, and heavy metals in the seawater met the demand of environmental criteria of Korea, US and UK
