In this study, we assessed the calcium nitrate reagent for possible application to the improvement of marine sediments, which are pollutants from organic matter produced through long-term pearl culture. A preliminary study was carried out using the calcium nitrate reagent with a simple laboratory experimental instrument. As the results, 1) the AVS concentration in sediments was reduced, 2) the production of hydrogen sulfide from bottom sediments was prevented, and 3) the possible elution control of phosphorous compounds from bottom sediments was observed. The addition of calcium nitrate to the organically polluted marine sediments could enhance the denitrifying activities.
