概要	Sediment remediation materials such as Mg and Ca were added to a microcosm consisting of bacteria, Cyclidium, Lecane, Philodina, Aeolosoma, Chlorella, Scenedesmus and Tolypothrix; and the respiration rate (R) and the production rate (P) were determined. The environmental impact risk assessment on aquatic ecosystem was conducted with P/R ratio as the functional parameter and the succession of microbiota as the structural parameter, in comparison with no addition system (control). The risk of Mg was estimated as half of Ca.
