Abstract

Nonylphenol (NP) is known as one of Endocrine Disrupting Chemicals (EDCs) is the degradation product of Nonylphenol ethoxylates (NPEs) being used as nonionic surfactant. NP is classified as an endocrine disrupter capable of interfering with the hormonal system of numerous organisms. In order to understand the behavior of NP in urban stream, this study was examined occurrence of NP in estuary of Nakdong River and Suyoung River. Water sampling for a raining season was performed in July 2011 and about the dry season was conducted in October 2011. During the survey period, the range of NP concentration in estuary of the Nakdong River was 137.1~10,931.5 ng/L and the average was 2,315.1 ng/L. Surface water of estuary of Suyoung River had the range of 144.0~2,469.6 ng/L and the average of 712.0 ng/L. It was found that NP concentration of Suyoung River and Nakdong River was similar or lower compared to results of studies in Korea and other countries.
