AWWA WQTC71514

The occurrence of thirty-one selected endocrine disrupting compounds (EDCs) andpharmaceuticals/personal care products (PPCPs) in Korean surface waters was investigated.Samples were collected from upstream/downstream and effluent-dominated creeks along the HanRiver, Seoul, South Korea, and analyzed by liquid chromatography with tandem massspectrometry (LC-MS/MS) with electrospray ionization (ESI) and atmospheric pressurechemical ionization (APCI). Most target compounds were detected in both the Han Riversamples (over 60%) and the effluent-dominated creek samples (over 75%). Iopromide, atenolol,TCPP, TECP, musk ketone, naproxen, DEET, carbamazepine, caffeine, and benzophenone werefrequently detected in both river and creek samples, although the mean concentrations ineffluent-dominated creek samples (< 3745 ng/L) were significantly higher than those in riversamples (< 1013 ng/L). However, the steroid hormones 17ß-estradiol, 17a-ethynylestradiol,progesterone, and testosterone, were not detected (< 1 ng/L) in both the river and creek samples.Numerous target compounds were found to be positively correlated (over0.8) to the conventional water quality parameters (chemical oxygen demand, biochemicaloxygen demand, dissolved organic carbon, and ultraviolet absorbance). Results of this studyprovide increasing evidence that certain EDCs and PPCPs commonly occur in the Han River asthe result of wastewater outfalls. Includes 35 references, tables, figures.
