dc.description.abstract | Eutrophication is a serious environmental issue in coastal areas, caused by increased nutrient concentration from externalsources. Nutrients could augment in the bottom sediment and be released into overlying water, acting as an internal nutrientsource. Converted oyster shell powders were used to evaluate the suppression of nutrients release from bottom sediments. Two kinds of oyster shell powder were applied into the sediment in the individual column with the control column. Thenatural oyster shell powder (NOSP) was composed of calcium carbonate and the functional oyster shell powder (FOSP)was composed of calcium peroxide. In the column where FOSP was applied, pH was increased due to hydrolysis of calciumperoxide in the overlying water. The concentration of dissolved oxygen in the FOSP-treated columns was higher than thatof the control column. The FOSP could suppress the release of ammonia nitrogen and phosphates from the sediment intothe overlying water. It was proven that FOSP can effectively adsorb phosphates from organically enriched sediments. Overall, the application of FOSP could effectively control nutrient release from the sediment to overlying water and helpreduce the eutrophication in the coastal areas. | - |
