The Nakdong River runs through highly industrialized and populated areas and has thus been polluted with numer-ous anthropogenic chemicals. As a growing number of new chemicals have been developed and used, the complexity of pollution in the receiving water has increased. In this study, LC-HRMS-based quantitative analysis was performed on 174 micropollutants in order to understand the status of new trace pollutants occurring in the middle and lower sections of the Nakdong River. In this analysis, 106 substances were detected at concentrations above the LOQ. Ben-zotriazole, used as a rust inhibitor, showed the highest median concentration, followed by metformin and diethylene glycol dibenzoate, all with maximum concentrations above 1,000 ng/L. Among pharmaceuticals, metformin, val-sartanic acid, metoprolol acid, and carbamazepine had high median concentrations. Similarly, high concentrations were observed for metolachlor ESA, 2-aminobenzimidazole, and flubendiamide among pesticides, and benzotri-azole, diethylene glycol dibenzoate, and dimethyl phthalate among industrial agents and other substances. The sample collection point with the highest number of substances detected was point N3, which also showed the greatest sum of median concentrations. With respect to substance groups, the highest median concentration levels were found at N2 for pharmaceuticals, N1 for pesticides, and N3 for industrial chemicals. Among the detected trace pollutants, a total of 44 substances were selected as priority substances after considering domestic and international water quality standards, detection concentration and frequency, and toxicity. These substances are suggested for preferential mon-itoring and management in the middle and lower sections of the Nakdong River.

Five sampling sites at the Gap Stream, a major tributary flowing into the Geum River, were classified according to their locations on the left or right banks of the latter; this was to allow an assessment of the pollution level in the river. To this end, the water quality and the sediments were examined twice -in the first and the second half of the year and before and after the rainy season. In terms of water quality, the concentration of nutrients increased during the second half of the testing period at sites G3 to G5, which are located just before the confluence of the stream and the river. The assessment results also showed that site G5-R required particular attention because of water pollution due to a frequent inflow of contaminants via surface sediments, in the second half of the study period after rainfall, when the WQI(Water Quality Index) was applied. In terms of the sediments, there was no site corresponding to Class IV or “heavily polluted”, according to the standards of the National Academy of Environmental Research. However, in the first half of the year, sites G4 and G5 on the left bank were polluted at LEL-SEL levels, which, according to the Ontario standards and the Org-Index assessment, indicated that they were “moderately polluted” or worse, indicating a concern regarding pollution from organic matter and nutrients.

We conducted a principal component analysis of PM2.5(particles with a diameter ≤ 2.5 μm) at four sites located in Chungcheongnam-do, a province of South Korea, to determine the level of pollution and characteristics of PM2.5components at each emission source. The four monitoring sites included a steel complex near Songsan-myeon (SS) area, a petrochemical complex near Dokgot-ri (DG) area, a residential complex near Mojong-dong (MJ) area, and a village near Naepo (NP) area. Samples collected at these sites were analyzed and the concentrations of mass, ion, carbon, and element in PM2.5were compared. The mass concentrations were found to be the highest in SS, followed by MJ, DG, and NP. The concentration of dominant ion species were recorded in a ascending order of NO3- > SO42+> NH4+ in MJ and SO42- > NO3- > NH4+ in SS, DG, and NP. The results indicate that MJ had the highest NOx concentration, which is emitted by automobiles. Moreover, MJ exhibited the highest organic carbon concentration of 5.67 μg/m3 and elemental carbon concentration of 0.51 μg/m3. The analysis of the elemental composition of PM2.5indicated a significantly higher concentration of Fe, Zn, and Mn in SS and As, V, and Ni in DG. Different component analysis results from each emission source suggest the need to understand the distribution of pollutants in each region while establishing measures to reduce PM2.5levels.

This study provided data that can be used to discriminate asbestiform and non-asbestiform amphiboles contained in landscaping rocks in recreational parks. The length and width of fibers being at least 5 μm long and with a minimum aspect ratio of 3:1 were measured using a transmission electron microscope and compared to an asbestos reference sample. The park samples were thicker than 1 μm (average 1.9 μm), while the Health and Safety Executive (HSE) reference sample averaged 0.3 μm in width, with 100% being thinner than 1.0 μm. The average aspect ratios were 7.1 for the park samples and 67.1 for the HSE reference sample. Based on these distributions, the amphibole fibers in sampled landscape rocks were thicker and had a lower aspect ratio than the reference sample. These results suggest that actinolite fibers in sampled landscape rocks cannot be classified into commercial-grade asbestos. This study can contribute to public policy for managing and controlling landscaping rocks containing naturally occurring asbestos (NOA) and be used to communicate the possible resulting health risks.
