Abstract
Relationship between the sum of nonylphenol and bisphenol A (SNB) and several inorganic ions in Sum river and Wonju stream were investigated. r2 value of SNB and sodium ion turn out to be 0.9445 which implies strong relationship between theses chemical species. r2 values of SNB and other inorganic ions (Ca, Mg, SO4, PO4) were lain only between the range of 0.0002 - 0.7940 which means no relationships between these chemical species at all. High r2 value between sodium and chloride ions (r2=0.9922) can be a good evidence that the source of sodium ion is NaCl which might be come from city sewage. Since nonylphenol and bisphenol A are derived from the decomposition of artificial surfactants, the above results indicate that the determination of sodium ion in river can be used as an another factor for a determination of sewage contamination portion in a river.
