摘要: Surface sediments (04 cm) were sampled at 40 stations from Ulsan Bay and its adjacent areas of Korea, to evaluate the contamination by sewage-derived organic matters using fecal sterols. Some sterols quantified gas chromatography coupled mass spectrometry (GC/MS). Total concentrations eight (coprostanol, cholesterol, cholestanol, epicholestanol, epicoprostanol, brassicasterol, stigmasterol) in vicinity varied 929 23,444 ng/g dry weight. The most predominant cholesterol coprostanol, accounting for total concentration coprostanol known as indicator human feces ranged 141 8,257 In particular, Jansaengpo Harbor Taehwa River exceeded value 1,000 weight, suggesting that these could be considered hot-spot zones municipal sewage contamination. molecular indices multivariate data analysis used assess origin sediments. Results showed major routes input through River.
