The present study demonstrates the occurrence of pharmaceuticals and personal care products (PPCPs) in surface water from the Mankyung River, South Korea. Samples collected at 5 Sites along the Mankyung River were assayed using a liquid chromatograph coupled with a tandem mass spectrometer (LC/MS/MS) for 13 PPCPs. Overall, 11 out of the 13 selected PPCPs, which span a range of therapeutic classes and one personal care product, were detected in surface water samples collected from the Mankyung River. The most prevalent contaminants were ibuprofen, with average concentrations ranging from not detected (ND) to 414 ng/l, followed by carbamazepine (ND-595 ng/l), atenolol (ND-690 ng/l), clarithromycin (ND-443 ng/l), mefenamic acid (ND-326 ng/l), erythromycin (ND-137 ng/l), fluconazole (ND-111 ng/l), levofloxacin (ND-87.4 ng/l), indomethacin (ND-33.5 ng/l), propranolol (ND-40.1 ng/l), ifenprodil (ND-35.4 ng/l), disopyramide (ND) and triclosan (ND). PPCP concentrations were highest in surface water samples collected downstream from a sewage treatment plant (STP), implying possibly insufficient removal efficiency of the PPCPs in the STP. Contamination by PPCPs such as ibuprofen, carbamazepine, atenolol, mefenamic acid and clarithromycin was high in the Mankyung River compared to concentrations in other countries.

Geochemical Characteristics of Intertidal Sediment in the Semi-enclosed Bays of the Southern Region of Jeollanam Province

To understand the geochemical characteristics of intertidal sediment in a semi-enclosed bay, we measured various geochemical parameters, including grain size, ignition loss (IL), chemical oxygen demand (COD), acid volatile sulfide (AVS), and trace metals (Al, Fe, Cu, Pb, Zn, Cd, Hg, and As), in intertidal sediment from three bays (Deukryang Bay, Yeoja Bay, and Gamak Bay) in the southern region of Jeollanam Province. The intertidal sediment in Deukryang Bay consisted of various sedimentary types, such as sand, gravelly muddy sand, mud, and silt, whereas the intertidal sediments in Yeoja and Gamak Bays were composed mainly of mud. The concentrations of IL, COD, AVS and trace metals in the intertidal sediments of the three study regions were relatively high near areas affected by input of stream waters and/or shellfish farming waste. The concentrations of organic matter and trace metals in Gamak Bay were much higher than those in Deukryang and Yeoja Bays, which appears to be due to the influence of anthropogenic pollutants, originating from the city and the industrial complex near Gamak Bay. The evaluation results of organic matter and metal pollution using the sediment quality guidelines showed that the intertidal sediments in the three study regions were not polluted in terms of organic matter and trace metals. In future, sustainable management for sources of organic matter and trace metal is necessary to conserve a healthy benthic ecosystem in intertidal sediments.

Distributions of Organic Matter and Trace Metals in Intertidal Surface Sediment from the Mokpo-Haenam Coast

et al. 2013

To evaluate the organic matter and trace metal pollution in intertidal sediment of the coastal zone, various geochemical parameters (grain size, ignition loss [IL], chemical oxygen demand [COD], acid volatile sulfide [AVS], and metals [Al, Fe, Cu, Pb, Zn, Cd, Cr, Mn, Hg, and As]) were measured for the intertidal surface sediment of the mainland and islands between Mokpo and Haenam in the southwestern coast of Korea. The surface sediments consist mainly of finer sediments, such as mud and silt. The concentrations of IL, COD, and trace metals in intertidal sediment were relatively high in the shoreline of the mainland than in that of islands and those in some stations exceeded the sediment quality guidelines (SQGs). Moreover, the concentrations of IL, COD, and trace metals (except As) in sediment showed relatively good positive correlations with mean grain size, indicating that the concentrations of organic matter and trace metals in intertidal sediment of the study region are dependent on grain size of sediment. Pollution evaluation for trace metals using geochemical assessment techniques, such as enrichment factor, geoaccumulation index, and SQGs, suggested that the intertidal sediments in the study region show light pollution with Cr and moderate pollution with As. More extensive interdisciplinary studies are required to determine the potential causes of As pollution in intertidal sediment.
