英文摘要: The use of granular steelmaking slag as a substitute for natural sand in the construction of tidal flats was investigated. Using an intertidal flat simulator, we evaluated dephosphorization slag mixed with 8% by dry weight of dredged sediment (DPS. +. DS) as a basal medium for the growth of benthic macro- and microalgae in comparison with silica sand mixed with 8% dredged sediment (SS. +. DS). Species compositions of macro- and microalgae were distinctly different between DPS. +. DS and SS. +. DS. The mean dry weight of macroalgae on DPS. +. DS was three orders of magnitude higher than that on SS. +. DS. Sediment shear strength and pH were higher in DPS. +. DS than in SS. +. DS or in the sediment of natural tidal flats. These results suggest that DPS contributes to changing the sediment environment, thereby changing the algal composition compared to the composition on natural tidal flats. © 2015 Elsevier Ltd.
