This study focused on improving the adsorption efficiencies of organic micropollutants, such as polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) using a passive water sampling device (PWSD) in a marine environment during summer. Two factors were considered when increasing the adsorption efficiency by improving the sampling rate (Rs) of PWSDs for target PCBs and PBDEs: 1. Controlling the invasion of the sticky organisms that cause biofouling by tearing the semipermeable membrane device (SPMD) inside the PWSD canister; 2. Preventing various suspended solids from clogging the PWSD pores. To resolve these problems, two types of enhanced PWSD samplers were devised, namely a round prest-type PWSD canister with zooplankton netting (netted), and a copper-coated prest-type PWSD canister. Copper is generally toxic to marine organisms. The netted and copper-coated PWSD samplers were deployed in Masan Bay and Ulsan Bay and their adsorption efficiencies for PCBs and PBDEs were compared with that of the prest-type PWSD sampler. The copper-coated PWSD had an Rs 1.5~1.8 times higher than that of the netted and prest-type PWSDs. A comparison of the adsorption amount of PCBs and PBDEs showed similar results, and copper-coated PWSD adsorbed more target compounds than the netted and prest-type PWSDs. The adsorption patterns of PCB homologues were similar regardless of the sampling site and sampler type, but those of PBDE homologues in the netted and prest-type PWSDs deployed in Ulsan Bay were somewhat different from the others. By comparing the adsorption amounts of PCB and PBDE homologues according to the octanol-water partition coefficients, it was found that the copper-coated PWSD adsorbed more PCBs and PBDEs than the netted and prest-type PWSDs, especially high molecular homologues. Based on these results, the copper-coated PWSD could be used to effectively prevent the biofouling of the SPMD membrane and clogging of the PWSD canister during both summer and winter.

The present study aimed to evaluate the concentration of odor substances and fine dust in areas where livestock farms are densely located, and to perform a correlation analysis of these concentrations to characterize the composition of fine dust. The mass concentration of fine dust in the areas tested was 33.6~46.68 μ/㎥ for particulate matter with a diameter ≤ 10 μm (PM‌10) and 16.85~32.82 μ/㎥ for particulate matter with a diameter ≤ 2.5 μm (PM2.5). These concentrations were higher than those in most of the neighboring areas. Ammonia concentration was measured in the range of 2.82~11.42 μ/㎥. The concentrations of the volatile organic compounds (VOCs), methyl ethyl ketone and toluene, were 0.24~11.82 μ/㎥, and 3.08~30.61 μ/㎥, respectively. Composition analysis showed that fine dust was composed of 8.2~10.2% carbon, 0.3~1.7% sulfur, and 0.1~0.9% nitrogen. Anions were detected at a higher concentration than cations, and SO42- was measured at the highest concentration. Of the four most prevalent metals detected (i.e., Al, B, Cu, and Zn), Al showed the highest concentration in both PM10 and PM2.5, and accounted for the majority of the total metal component (84.7% and 82.2%, respectively). A correlation analysis of find dust with ammonia and VOC (methyl ethyl ketone and toluene) concentrations showed that ammonia generated from livestock facilities affected the formation of fine dust in nearby areas. VOCs emitted from nearby industrial facilities were also considered to contribute to the constituents of fine dust.

The source contributions in PM-2.5 were investigated in two residential areas (i.e., Yeosu and Suncheon of Gwangyang Bay) using a source apportionment model. As a result, eight sources have been identified such as secondary sulfate (31%), mobile (16.8%), secondary nitrate (15.9%), soil and road emission (15.2%), biomass burning (11.5%), oil combustion (4.2%), coal combustion (3.7%), and industry activity (1.7%) in the Yeosu area. In the Suncheon area, secondary sulfate (27.3%), biomass burning (16.4%), and secondary nitrate (15.3%) were investigated as the major sources. Clustering of the trajectories revealed dominant wind patterns associated with high concentrations due to long range transport. In conclusion, this study shows that the source apportionment model yields results for identifying pollutant sources in two receptor locations.

Various volatile organic compounds (VOCs), including aldehydes, are present in fried food being cooked in high-temperature oil. In this study, real-time VOC concentration was measured in the upper part of a large pot in the cooking room using Proton Transfer Reaction Time-of-Flight Mass Spectrometry (PTR ToF MS) for 3 days (roasted on the first day, fried on the second day, and simmered on the third day). The average concentration of diacetyl was the highest on the first day of stir-frying and steaming. The highest concentrations of formaldehyde was on day 3 when pork was cooked in sugar and sauce. Formaldehyde, 1,3-butadiene, acrolein, diacetyl, and naphthalene were detected during the frying process on the second day, and were detected in descending order of boiling point. In addition, various VOCs such as methanol were detected. The maximum/minimum concentration ratio was the highest for acrolein (3,030), so it was confirmed that many aldehydes were generated during frying. Although there is a limit to direct comparison with Occupational Exposure Limit as a result of area sample by PTR ToF MS, the mean concentrations of formaldehyde and diacetyl during the frying operation for 15 minutes were 232 ppb and 16 ppb, respectively, which was 80% of the American Conference of Governmental Industrial Hygienists Threshold Limit Value-Short Term Exposure Limit. After the frying was over, the VOC concentration began to decrease, and it took more than 3 hours to lower the VOC concentration to the level before the oil was heated. As various harmful gaseous substances are generated when cooking deep-frying, improvement methods such as using oil with high boiling points and developing respiratory protection programs should be devised.

In Ulsan, large-scale industrial facilities emit large amounts of various odors and hazardous air pollutants. This study investigated the current status of odor problems in Ulsan and suggested a comprehensive management system. Owing to the geographical conditions, weather conditions, major industrial complexes, and management of emission facilities, complaints about odor occur mainly in summer. The city authority responds to odor problems by preparing comprehensive measures to prevent odors and introducing unmanned sampling devices, real-time monitors, and a mobile monitoring system. Major odor substances and pollution characteristics can be identified through these efforts, but information on specific odor substances, complex odors, emission sources, and transport pathways is lacking. Therefore, it is necessary to upgrade the current monitoring system and establish a comprehensive management system to solve this problem.

To identify the origin of major pollutants, we determined the distribution of stable isotopes of δ15N and δ18O in nitrate extracted from water samples and sediments collected at two-month intervals during 2019-2020 from the North Hangang River, Korea. Stable isotope ratios were measured to investigate nitrogen contamination sources in the water system. This study determined that the North Hangang River was affected by soil organic matter, livestock manure, and domestic sewage, and that the streams and rivers flowing into the main stream of the North Hangang River were affected by domestic sewage or livestock manure, resulting in relatively heavy nitrogen isotope ratios. Generally, the concentration of nitrate nitrogen was higher in the inflowing streams (Geumsan, Hongcheon, Mukhyeon, and Gyeongan district) than at the main stream. Nitrogen pollution due to chemical fertilizers and soil organic matter were different in 2019 and 2020, and the ratio of stable nitrogen isotopes decreased owing to the influence of rainfall. Sediment in the North Hangang River has been affected by agricultural soil organic matter and livestock manure, showing the necessity to nitrogen pollutant management, particularly with pollutants such as soil organic matter and livestock manure.

β-Methylamino-L-alanine (BMAA) is an emerging algal toxin that has drawn attention because it can cause neurodegenerative diseases, including Parkinson's disease and Alzheimer's disease (AD). Therefore, it is necessary to develop a sensitive analytical method for BMAA, an emerging cyanobacterial toxin, to determine whether a trace amount is detected in the water resources and treated water. In this study, we developed a simple and sensitive analytical method for BMAA using liquid chromatography-tandem mass spectrometry (LC-MS/MS) with direct injection. The method was validated for linearity of calibration, limit of detection, limit of quantitation, accuracy, and precision. The limits of detection and quantitation were in the range of 0.030 ?/L and 0.096 ?/L, respectively. The optimized method was used to measure the concentrations of BMAA in surface water from each weir point of the Geum River, Nakdong River. Sampling and analysis of drinking water treatment plants of the Geum River, Nakdong River were applied to samples for each process.
