We investigated the changes in a contaminated bay sediment when some oxygen releasing compounds(ORC) were put in it: is was found that the ORCs such as CaO2 were good at suppression of H2S and removal of phosphorus by changing the neutral pH into weak alkaline pH. In particular,
performance of CaO2 was the best of all probably because of the faster establishment in O2 generation
and weak alkaline condition. Consequently, it was concluded that ORCs instead of sea cultivation or red clay spreading would promote the conditions better in which O2 should kept being generated and
active microbial population for bioremediation should be maximized.
