Abstract
In regards to water pollution problems in closed coastal zone or rivers, municipal wastewater have been a major target of the environmental measurement after some effective pollution control measurements in decades in developed countries. International corporation or agreement have been developed for international coastal area or rivers including Global Programme Action (GPA), Global International Waters Assessment (GIWA) and Regional Seas Programme lead by UNEP as countermeasures to marine pollution. Environmental accounting housekeeping books for municipal wastewater has been proposed as an effective water pollution reduction measurements in the life of ordinary people in Ebigawa River drainage area, urban river running into Sanbanze tidal zone, Tokyo Bay, in this symposium last year. After that, water pollutants load per capita running into the coastal area has been proposed as an indicator for quantitatively evaluate loads of municipal life onto coastal area. This indicator was applied to six international coastal and lakeside regions and comparative analysis with an economic indicator was conducted in this paper. Whereas BOD load per capita running into aquatic zone has its peak at GDP per capita of 4, 000 and phosphorus load 10, 000. Nitrogen load does not have clear peak for GDP per capita.
