統一水質指標の適用と汚濁負荷量に関する研究 -ライン川を対象として-

Abstract

A composite index is developed to assess source water quality at global scale. In this study we have testified application of WQ indices developed by GEMS/Water Program. The approach for development was three-fold: (1) to select guidelines from the World Health Organization that are appropriate in assessing global water quality for human health, (2) to select variables that have an appropriate guideline and reasonable global coverage, and (3) to determine, on an annual basis .The developed index includes frequency and extent to which variables exceeded their respective WHO guidelines, at each individual monitoring station.
