Abstract
Alkylphenols (8), chlorophenols (2), bisphenol A, coprostanols (2) andcholesterol compounds were analyzed in the surface water and surface sediment takenfrom Gwangyang Bay and surrounding streams in 2001. Among the target analytes,nonylphenol and dihydrocholesterol compounds were detected with high concentra-tion and high frequency. t-Octylphenol, bisphenol A and coprostanols were detectedonly in some sediment samples from the stream. The highest concentration of nonyl-phenol was determined in stream sample, and concentrations of nonylphenol in theinner part of Gwangyang Bay were higher than those in the out part. Nonylphenol con-centrations in the surface seawater and surface sediment samples ranged from 4.0 to74.0 ng l-1 and from 3.1 to 74.3 ng g-1 dry wt., respectively. Partition coefficient (LogK oc)of nonylphenol between sediment and water was 4.8. Nonylphenol and dihydrochole-steol concentrations in the stream surface sediment samples ranged from 4.6 to 808.6and from 78.4 to 1133.6 ng g-1 dry wt., respectively. Relatively high concentrations ofnonylphenol were found in the stream samples which are flowing through industrialcomplex area, while dihydrocholesterol concentration was relatively high in thestream samples which are flowing through only municipal area. Seaward decreasingtrend in nonylphenol concentration was observed from the Seomjin River estuary tothe Gwanyang Bay. Such trend was best supported by the strong correlation betweennonylphenol concentration and salinity in water samples.
