| 内容記述 | The concentrations of some heavy metals related closely to primary production in an estuarian ecosystem such as Mn, Fe, Co, Zn, Cu, and Ni, were measured in samples of filtered water, suspended particulate matter, and bottom sediments in Nagura River estuary, Ishigaki Island, Ryukyu Islands in 1980. The distributions of inorganic nutrients such as phosphate and silicate were also investigated in the same region. The concentrations of most of the heavy metals in the water were rather constant regardless of the tidal levels when the samples were collected or the different sampling sites. Manganese, to the contrary, was found in conspicuosly higher quantity near river area suggesting its supply in soluble form is related to river water influx. The concentrations of metals in the sediments differed at various sampling sites and those in the suspended particualte matter were far higher in the samples nearer the river. Such a change at the river mouth regions was remarkably noted in Mn, Ni, Fe, and Cu. The distribution of phosphate and silicate indicated that the river is a major source of supply of these matters to the ocean. |
