In this study, to characterize chemical compositions and identify the sources of PM2.5 in the urban area of Jeju, Korea, PM2.5-bound concentrations of 8 ionic species and 12 elements were measured from samples collected at the downtown area from January to December 2017. Positive matrix factorization (PMF) was applied to these PM2.5 data-sets to identify the diverse sources in Jeju City. The average PM2.5 mass concentration for the study period was 18.31±9.72 μg/m3. The contributions of water-soluble ionic species, elements and unknown components to PM2.5 mass were 55.8%, 2.1%, and 42.0%, respectively. PMF analysis showed that a total of six source types were identified to be important. These sources are the industry related source, secondary sulfate and oil combustion, soil, biomass burning and vehicles, secondary nitrate, and sea salt.

In this study, we purified an environmental pollutant (metamifop) by re-crystallization under various conditions and prepared four kinds of high-purity reference materials (RM) that show small variations in purity among each other. To measure their purities with uncertainty, four different analytical methods were employed: differential scanning calorimetry (DSC), peak area normalization (HPLC), external calibrant (HPLC), and quantitative NMR (q-NMR). The highest purity of metamifop RM, determined by q-NMR, was 99.02% with an uncertainty of 0.64% compared with 99.36% (with 0.12% uncertainty), 99.46% (with 0.53% uncertainty) and 99.84% (with 0.29% uncertainty), determined by DSC, external calibrant, and peak area normalization, respectively. Most of the evaluated purities are within the calculated uncertainty range.

Water blooms, formed by cyanobacteria such as Microcystis, Aphanizomenon, and Anabaena have been occurring frequently in lakes and rivers in Korea. As such, there is a need to develop a sensitive method to determine cyanobacterial toxins to minimize potential hazards in raw water resources. In this study, we developed a highly sensitive analytical method for seven cyanobacterial toxins (microcystin-LR, -RR, -YR, -LA, anatoxin-a, nodularin, and cylindrospermopsin) using liquid chromatography-tandem mass spectrometry (LCMS/ MS) with direct injection. The method was evaluated in terms of calibration curve linearity, limit of detection, limit of quantitation, accuracy, and precision. The limit of detection and limit of quantitation were in the range of 0.010-0.026 μg/L and 0.030-0.081 μg/L, respectively. Good accuracy and precision was also obtained. The optimized method was used to measure the concentrations of the seven cyanobacterial toxins in river water from Nakdong River, and microcystin-RR, -YR, and -LR were detected.

The results of environmental testing and inspection are important as objective data for judging whether the basic criteria of environmental policies and standards are fulfilled. The results of environmental testing and inspection are measured by standard methods of an environmental analysis (Environmental Test Standards (ES) and Korean Industrial Standards (KS)) for quantifying environmental pollutants in the test samples. Therefore, a procedure is required to provide objective evidence that the standards of environmental analysis are appropriate for use and are reliable and reproducible. This study is performed to establish a quality control plan for standard environmental test methods because the operation management of ES and KS are integrated into the National Institute of Environmental Research. The research conducted on the literature available from all over the world has made it possible to develop quality and validation method for the standard to meet the performance and quality level when test methods are developed. The validation of the environmental test methods in the European Union is carried out in two stages robustness test and inter-laboratory test. Parameters of robustness test include selectivity, sensitivity, detection limit, quantitation limit, medium effect, etc., and involves setting the minimum recommended number of tests and the target value. Therefore, this study aims to establish 'Guidelines for Validation of Standards of an Environmental field' to ensure uniformity and accuracy of the methods before enactments and amendments of ES and KS.

This study was performed to analyze the monthly characteristics of sewage sludge by analyzing the basic data required for recycling in thermal power generation or as incineration plant auxiliary fuel. Analytical samples were collected from two sites every month for three years, for 72 samples total. Proximate analysis (such as moisture, ash, and volatiles), elemental analysis (C, H, O, N, and S), tube furnace-ion chromatography, and calorimetry (heating value) were performed to evaluate the sludge heating characteristics. Resultantly, the moisture values were 73.2-89.5% (average 82%), the volatile values (dry basis) 44.8-83.0% (average 66.5%), and the low heating values (10% moisture basis) 2,014-4,304 kcal/kg (average 3,248 kcal/kg). The low heating values (10% moisture basis) exceeded the recycling standard of 2,000 kcal/kg, confirming the possibility of recycling the sludge as fuel. When we looked at the monthly heating value of the sewage sludge, it tended to be high in November, December, January, and February. Thus it could be concluded that sewage-sludge-based fuels generated in winter could obtain higher quality with higher heating value when sewage sludge is recycled as fuel.

The cellular uptake of gold nanomaterials (AuNPs) was investigated in human liver HepG2 cells exposed to 0.5 or 1 μg/mL of AuNPs for 24 hours. After the exposure period, the total gold concentration in the medium and cells was observed to have increased significantly in a dose-dependent manner; gold nanomaterials were mainly present in the medium, while some were present in the cells. SP-ICP-MS showed that the AuNPs concentration increased in the medium and cells, but the results were lower in comparison to the total gold concentration measured by ICP-MS. This difference was presumably due to the fact that AuNPs were ionized and aggregated, and only a part of them retained a shape that is detectable by SP-ICP-MS. The median size of AuNPs remained similar after 24 hours to that at initial exposure. In conclusion, this study confirmed the applicability of SP-ICP-MS for the analysis of the concentration and size of AuNPs and the distribution pattern of AuNPs in HepG2 cells.

Upo Wetland, in Changnyeong-gun, Gyeongsangnam-do, is the largest inland wetland in Korea and a habitat for various species. However, due to agricultural activities in the surrounding area, diverse organic pollutants such as pesticides have flowed into the wetland ecosystem. This study analyzed the exposure of Upo wetland to organic pollutants (e.g., pesticides and pharmaceuticals) using LC-HRMS (Liquid Chromatography-High Resolution Mass Spectrometry). Twenty-six pesticides and pharmaceuticals were selected and quantitatively analyzed for target screening. As a result, eight pharmaceuticals (e.g., fluconazole, lincomycin, metformin, valsartan) and eight pesticides (e.g., tebuconazole, metalaxyl) were quantitatively identified. The major pesticides were tebuconazole (230-3,900 ng/L) and metalaxyl (53-980 ng/L), whereas metformin (20-220 ng/L) was the pharmaceutical with the widest concentration range. Metabolites of the two major pesticides TEB_M324c and metalaxyl acid were identified tentatively via suspect and nontarget screening which also identified several other substances including benzotriazole, carbendazim, diazinon, hexaconazole, methabenzthiazuron, tricyclazole, niflumic acid, 2-aminobenzimidazole, 2-isopropyl-6-methyl-4-pyrimidinol, valsartan acid, and retrorsine.
