内容記述タイプ Abstract
内容記述 Water samples were collected from18 rivers in Niigata Prefecture during September of 1986. Tritium concentration and seven major ionic constituents, including Na^+, K^+, Ca^<++>, Mg^<++>, Cl^-, HCO^-_3 and SO^<-->_4 ions were acquired to determine if they reflect the nature of individual rivers. The results obtained are as follows. Tritium concentrations of the river water range from 24 pCi/l to 68 pCi/l and tend to be slightly higher than the concentrations in the precipitation collected at Niigata City. From the view point of decay-properties of tritium, these water samples are apparently affected by the precipitations bearing the artificial addition of tritium due to the past thermonuclear tests in the atmosphere. It was also suggested that the river water consists not only of runoff, but also of additional ground water to a large extent. As compared with the water quality about 40 years ago, the major ionic components of waters in the Miomote and the Agano Rivers have been scarcely changed, while the artificial pollution in the Shinano and the Seki Rivers has proceeded slightly. From these results, it was ascertained that the major ionic components in river water has not changed in general without pollution within a short period like several decades. The evidence above also supports the idea that the tritium concentration and chemical components of river water are subject to the feature of aquifers (scale, geology, residence time etc.) in the drainage basin.
