Surface sediment samples collected from Busan coastal area of Korea were analyzed for molecular markersof organic wastewater compounds, i.e., fecal sterols including coprostanol (COP) and nonylphenolic compounds(NPs), to assess anthropogenic contamination and to characterize the main routes of wastewater to thecoast. Concentrations of COP, a marker of municipal wastewater contamination, ranged from 7.61 to 11,684ng/g dry weight in sediments, while concentrations of NPs (nonylphenol, and nonylphenol mono- and di-ethoxylates),a marker of industrial wastewater contamination, ranged from 50.5 to 2,166 ng/g dry weight in sediments. Their detection in all of the sediments indicates widespread pollution by wastewater. Moreover,relatively high levels of COP and NPs in the present study suggest significant pollution by both urban andindustrial wastewater input, compared with previous results. The spatial distribution of COP levels was statisticallysimilar to that of NPs, indicating that these compounds may have similar discharge points, transport,mixing, and deposition in the coastal area. Levels of COP and NPs were much higher at stations close to theports, and rivers that pass through the urban center of Busan City. These results suggest that considerableamount of wastewater compounds are discharged through direct input, combined sewer overflows, and urbanrunoff to Busan Habor.
