Abstract

The Environmental Quality Standards for Water in Japan, established in 1971, have been revised 16 times in the past. The main content of the revisions consisted of addition of standard items, tightening of standard values, and change in measurement methods. To judge the level of attainment of the standards, which have been growing stricter, knowledge and proficiency in the appropriate measurement of the water environment are important. The present review, which focuses on the measurement methods for each standard item and gives an overview of the history and points of revision of the standards, will contribute to analyzing and understanding actual conditions in the water environment.
