In 1982,Environment Agency of Japan defined a regulation on total phosphorus and the total nitrogen concentrations in lake water as an index of environmental quality standard to protect from the pollution. At the same time, an official method for the determination of total phosphorus and total nitrogen was published. Therefore, the concentrations of these compounds in lake and river water in the south area of Hyogo prefecture in Japan were determined to be compared with the regulation of the environmental quality standard. Water samples were also taken from the area and Lake Biwa and Yodo River as comparison. The 18 samples among 29 of lake water exceeded the limit (0.1 mg/l) of total phosphorus, while the 19 samples among 29 of lake water exceeded the limit (1.0 mg/l) of total nitrogen.
