In this study, we investigated analytical procedures for obtaining accurate and reliable total organic carbon (TOC) measurements in particle-containing water samples. Most TOC values obtained at several laboratories for cellulose particle-containing samples (20~100 μm, 10~100 mg-C/L) did not meet the quality control cri-teria (i.e., 80%). Therefore, in this study, the influence of suspended particles (particle size, and concentration) on TOC analytical procedures (sample injection, purging time, washing, dilution etc.) and TOC measurements (accuracy and precision) was evaluated specifically for cellulose particle-containing water samples, and various other environmental samples (soil, road sediment, sewage sludge). Results of the washing experiment showed that about twice the washing volume was required, compared with that required in conventional TOC analysis for dissolved samples, for the removal of residual particles in the apparatus after the measurement. Also, a normal injection method was preferred for sample injection and an appropriate sample preparation method (without dilution) and proper concentration ranges (10~100 mg-C/L) are suggested based on the results of our study.

The purpose of this study was to evaluate the sediment contamination levels of the midstream and downstream areas of the Gap Stream, a major tributary of the Geum River in Korea. Ten monitoring stations were selected to investigate metal contaminations in the sediment, with samples taken in May and October 2018, before and after rainy season respectively. Comprehensive evaluation was conducted according to both foreign and Korean standards for freshwater sediment contamination assessment as well as relevant test methodology. The analysis of sediment particle size, sediment contaminant distribution, the environmental effects on bodies of water, and the correlation between sediment variables were all included in the study. The evaluation of the results, using the mean PELkquotient(mPELkQ), demonstrated that five stations before and seven stations after the rainy season had high possibilities of toxicity in the benthos. Two positions were determined to be within the “very poor” range level of contamination stages prior to the rainy season. The Pollution Load Index (PLI), used to determine the existence or non-existence of man-made contaminants, indicated the presence of man- made contamination at every station. In the majority of stations, contamination levels of Hg, Cd, and Cu were determined to be class II or higher, according to South Korean standards. Enrichment Factor and Index of Geoaccumulation(Igeo) analyses showed that the contaminants with the highest levels present were Hg, Cd and Zn. In particular, Hg was found to be the most concerning metal present with a level III contamination, indicating heavy to extreme contamination in some stations.

This study investigates the concentration levels of PM10 and PM2.5 in the Jeju area in 2016 and the inflow routes of air masses during the high particulate matter concentration events (high-PM events) that occurred in the Jeju area using Hybrid Single Particle Lagrangian Intergrated Trajectory Model. The hourly mass concentrations of PM10 and PM2.5 in 2016 were obtained from three air pollution monitoring sites (Yeondong, Ido, and Donghong) in the Jeju Island. The average PM10 and PM2.5 concentrations at the three sites were 41.5, 45.7, and 36.4 μg/m3 for PM10 and 24.2, 23.2, and 18.5 μg/m3 for PM2.5, respectively. Statistically significant differences (p<0.001) were observed between the PM concentrations at the northern (Yeondong and Ido) and southern (Donghong) parts of Mt. Halla. The PM10 and PM2.5 concentrations were simultaneously increased during the high-PM events in the winter season. Furthermore, a time lag was observed between the PM concentrations at the northern and southern parts of Mt. Halla during the high-PM events. A backward trajectory cluster analysis was performed to analyze the effects of the inflow air mass on the air quality of the Jeju area during the high-concentration events of PM10 and PM2.5. The increase in PM2.5 concentrations for the high-PM events, except for the Asian dust events, was mainly influenced by the air masses transported from the eastern and northeastern areas of China.

The Korea Institute of Nuclear Safety (KINS) has been monitoring the radioactivity in the atmospheric fallout for a long time. Results show that 137Cs was always below the Minimum Detectable Activity (MDA) except when the Fukushima Nuclear Power Plant accident occurred. The Ionizing Radiation Center at Korea Research Institute of Standards and Science (KRISS) also collected the atmospheric fallouts at the end of each month and measured 137Cs using a well-type HPGe detector (GWL-300-15-s) since 2012. The annual 137Cs depositions ranged from 79 to 225 mBq/m2/year. 137Cs detected in the present atmospheric fallout is considered to be originated from the atmospheric nuclear bomb tests conducted by the USA and the former Soviet Union in the 1950s and early 1960s. The results of this study indicate that the well-type HPGe detector is more suitable for small size environmental samples (i.e., 0.5 - a few grams) and extreme low activity levels compared with the conventional detector (GEM90P4-95).

As the number of new chemicals increases, traditional animal testing has limitations in evaluating the toxicity of chemicals. In Europe and the United States, the use of non-animal alternative toxicity test methods for chemical regulation is encouraged and related research is actively carried out. In the United States, the ToxCast program is in progress using high-throughput screening (HTS) techniques. The program produced HTS in vitrotest results for 1200 assays and 9000 chemicals to develop chemical toxicity prediction models and set the priorities for toxicity assessment. In this review, we explored the outline of ToxCast, the types of assays used, and the progress of each phase. We also explored how to analyze the numerous toxicity data generated through the ToxCast program, including pre-processing, dose-response model fit, conclusion and categorization. Finally, implications for domestic utilization of the ToxCast database are derived.

DDTs are still potential hazard chemicals due to the properties of POPs, even though they have been banned in Korea since the 1970s. To assess pollution levels of the sediment we analyzed DDT isomers of 109 sites in 39 major lakes in Korea. For this assessment, we used sediment quality guidelines, analyzed the relationship of total DDTs concentration to particle size and total organic carbon concentration, and estimated the time when the DDTs came into the sediment by analyzing the isotopic composition ratio of total DDTs. Analysis Results are, the total DDTs concentration in the range of N.D.(<0.2 ng/g-dw)~14.6 ng/g-dw (2.32 ± 2.34 ng/g-dw) was similar to the study result of rivers in Korea and was relatively lower than the study result of rivers in other countries. Pollution assessment results showed that there were no sites exceeding probable effect concentration(PEC), but Chuncheon 2, Chuncheon 3 and Boryeong 3 sites exceeded the threshold effect concentration(TEC).The DDTs concentrations were not associated with particle size while it showed a correlation with total organic carbon(p<0.05). Isotopic composition ratio analysis, showed relatively recent influx of DDTs in to the Boryeong 3. Considering this result, the sites that the DDTs exceeds the TEC should be checked for impact on benthos or human health, accordingly assessing the improvement of sediments in the sites. Also, is necessary to investigate areas surrounding the sites. The sediment quality guideline used for this study is based on toxicity data from other countries. It is expected that the follow-up study would establish the data base of DDTs concentration in sediment and the toxicity on the benthos inhabiting the Korea, providing the base to develop guidelines reflecting Korean sediment quality and ecosystem.
