(1) The horizontal distribution of carbon, nitrogen, and phosphorus in the surface sediments (0-3 cm layer) from 19 stations was surveyed. The contents of all three elements were low at stations below 2.5 m water depth near the shore as compared with stations above 2.5 m water depth offshore. Also, the C/N and C/P content ratios in the former were larger than these in the latter. It was indicated that these features reflected the effect of the dredging work on the bottom sediments in recent years. (2) Aa for the vertical distribution of 15-18 cm core sediments from various stations, the contents of all the elements were the highest at surface layer, and decreased rapidly with depth downwards. This features was remarkable in the stations of water depth below 2.5 m, showing the recent effect of heavy water polltion. In a 2.3 m core sediment from the lake center, the vertical variations of these contents was considerably similar with each other. The C/N content ratio decreased slightly with depth downwards and was 7-8 in lower layer than 2 m. On the other hand, the C/P and N/P increased. (3) The distribution of organic-phosphorus was holizontally and vertically unifom and the content was about 0.8 mg/l. Therefore, it was assumed that the organic-phosphorus was existent in a chmically and biologically stable state in the sediment. The ratio of the organic-phosphorus to the total phosphorus was about 20-30 %. |
