摘要：In order to clarify daily variations of anionic and nonionic surfactants levels in the river waters, the atomic absorption spectrophotometric method reported previously was used. Water samples were taken from the two rivers close to Kobe Women's College of Pharmacy for about two months (1982. Oct.-Dec.). The results showed that there was a significant correlation between the levels of anionic and nonionic surfactants. The correlation coefficients between these two surfactants levels in the two rivers were 0.919 and 0.858 (p<0.01), respectively.
