抄録

For the purpose of reducing CO₂ contents in the atmosphere, one of the solution is said to grow the biomass of phytoplankton by it's photosynthesis, that is enhances it's biological pump. When steelmaking slag is applied to the sea, the nutrient like phosphate and silicate, and ferrous ion as a micro nutrient, which is indispensable for the growth of phytoplankton, especially diatoms, is considered to be supplied sufficiently.<BR>This time, large tank test adding steelmaking slag was carried out, and increase behavior of phytoplankton was investigated. And at the same time, the behavior of various kinds of chemical elements which dissolves from steelmaking slag to the sea water examined in detail.<BR>The results show that contamination problems from the steelmaking slag which was applied to this experiment cannot be recognized. Behavior of dissolved element is compared to some experimental systems, for example, large tank test and beaker test etc., using analytical model. Furthermore, three dimensional simulation of dissolved nutrients from steelmaking slag was also investigated.
