Abstract
On the basis of papers and policy documents on pollutant loads, measures of dissemination and environmental education which highlights water pollution of an enclosed coastal sea, Sanbanze, Tokyo Bay, and a municipal life were proposed in this paper. Simple pollutant load analysis using water quantity and quality data available on websites of Chiba prefecture and its cities was conducted to examine what could be analyzed on the basis of data and information that can be easily accessed by an ordinary citizen. Pollutant loads per capita flowing into Sanbanze tidal coastal zone were calculated as 0.3-5.2g-COD person-1·day-1, 2.5-4.3g-N person-1·day-1 and 0.22-0.43g-P person-1·day-1 respectively. COD and T-N loads of “combined jokaso and riverside water purification facility” population and T-P load of wastewater treatment plants (WTPs) population were calculated as minimum of pollutant loads per capita flowing into water area are proposed as an effective index for domestic wastewater management, and the basic concepts of environmental accounting housekeeping (EAH) books for domestic wastewater are proposed for the purpose of information dissemination and environmental education as regards water pollution.
