Effects of three iron material treatments on hydrogen sulfide release from anoxic sediments

Effects of three iron material treatments on hydrogen sulfide release from anoxic sediments

In eutrophic coastal regions, hydrogen sulfide (H S) is a harmful material released from sediments under anoxic conditions. To suppress its release, we conducted laboratory experiments and assessed the impacts of treatment with three iron materials (Fe, Fe O , and FeOOH), focusing on the area-specif...

Zusammenfassung:In eutrophic coastal regions, hydrogen sulfide (H S) is a harmful material released from sediments under anoxic conditions. To suppress its release, we conducted laboratory experiments and assessed the impacts of treatment with three iron materials (Fe, Fe O , and FeOOH), focusing on the area-specific H S release rate. These materials qualitatively exhibited a substantial suppression of H S release; however, smaller treatment levels (
