Abstract :
In the enclosed sea area, a large amount of organic matters deposited in seabed sediment because rich nutrient through the river cause the massive generation of phytoplankton and seaweeds. As the result, hydrogen sulfide is eluted from the organic-rich sediment and stimulates the additional hypertrophic effect. However, there is an incomplete understanding of a mineralization process from sediment to bottom layer water upper seafloor. The purpose of this study has been to develop measurement method for hydrogen sulfide concentration in pore water. Author proposes the new method for absorptiometric analysis of ultraviolet spectrometry spectrum from pore water in sediment using screw cap cell.
