Abstract |
Nonylphenol(NP) and Bisphenol A(BPA) are endocrine disruptors causing estrogenic effect and genital trouble etc This study was carried out to survey the characteristics of NP and BPA distribution in the surface sediments of Nakdong river. Concentration of NP and BPA ranged ND-25,144 and ND-57ng/g-dry wt in October, ND-56,696 and ND-84ng/g-dry wt in January, and ND-49.569 and 1 -48ng/g-dry wt in March respectively Results of grain size analysis, gravel was dominated at the upper reaches, sand at the middle reaches and mud in the river estuary dyke Maximum values of NP and BPA were found at river estuary dyke that sediment was composed of mud nearly and organic matters and metals was severely contaminated High levels of nomalized NP and BPA by mud showed at industrial complex nearby the Kumho river that was greatly affected sewage and wastewater NP and BPA concentration of this study area were relatively high in comparison with the other sites, it is necessary to control of noxious materials input to the water environment for water quality management |
