摘要：In order to clarify the variations of anionic surfactants level and BOD value in river water, the former was determined by the atomic absorption spectrophotometric method reported previously and the latter was determined by the testing method for industrial waste water described in JIS K 0102. Water samples were taken from three rivers close to Kobe Women's College of Pharmacy daily, except on Sundays and holidays, for one month. Both anionic surfactants levels and BOD values showed significant daily variations.
