Geochemical studies were conducted on natural waters in TAKANA and KOMI regions and the main four rivers in IRIOMOTE Isl. Sampling was conducted in Septemer 1970 at TAKANA and KOMI regions and the Nakama river, and in September 1971 at the Urauchi, Kuira and Nakara river. 1) Acidic natural weter in TAKANA region were reported at the newspaper as "hot springs." However, the authers concluded that waters are not hot springs, for the fluxes are little and the water temperature is low (28℃). 2) Gregariousness of Mangrove is seen from the river mouth to an upperstream about 6 Km at the Urauchi river to about 5 Km at the Nakama river, to about 4.5 Km at the Nakara river and to about 4 Km at the Kuira river and the Cl concentrations at the limitting points of Mangrove are respectively 1/6, 1/5, 1/3 and 1/2 of sea water at the Urauhi, Nakama, Nakara and Kuira river. However the range of salinity is not constant, salinity may be one of important factors for growth of Mangrove. 3) Chemical ompositions (Ca and HCO_3) of land waters are grouped to different patterns at each river. That different chemical patterns reflect diffrent natural envirom,emts at each river. |
