| 内容記述 | Lake Nakaumi, San-in area, is one of the largest blackish lake in Japan. Recently, sedimentation of organic flock named “Hedoro” becomes a serious problem, because the enrichment of organic flock may damage the ecological system. In order to reveal geochemical behavior of elements in the organic-rich sediment of the brackish lake during early diagenesis, the chemistry of upper 60 cm sediment and porewater from the harbor of Yasugi located on southeastern part of Lake Nakaumi was examined. Total organic carbon (C_org) and total nitrogen (N) concentrations of the sediment are 3.0 to 5.5% and 0.3 to 0.6%, respectively. C_org/N mole ratios in the sediment ranges from 10 to 13 suggesting that organic matter in the sediment originate mainly from phytoplanktons. The C_org and N concentrations decrease with depth, suggesting organic degradation during diagenesis. The porewater shows low Eh and decreasing of SO_4 ^2- concentration with depth. Hence the degradation of organic matter is accompanied by sulfate reduction. Whereas, relation between Eh and pH in the porewater show that HS^- concentration is less than SO_4^2- concentration. Considering the high sulfur concentration up to 4% in sediment, HS^- generated by the sulfate reduction is probably removed by the deposition of sulfide. | |||||
