In this study, the size distributions of airborne particulate matter (PM) associated ionic species (Cl-, NO3 -, SO4 2-, Na+, NH4 +, K+, Mg2+, and Ca2+) and pollution sources were investigated. PM samples were collected using two micro-orifice uniform deposit impactors (MOUDIs) with 11stage cut-sizes (0.056, 0.10, 0.18, 0.32, 0.56, 1.0, 1.8, 3.2, 5.6, 10.0, and 18.0 μm) at residential and industrial sites in Ulsan, Korea. At both sites, anthropogenic ions (SO4 2-, NO3 -, and NH4+) contributed to over 60% of the total ion concentrations in PM and were dominant in fine particles. During the high PM episodes, SO42- (42%) was the main ion at the industrial site due to the influence of petrochemical and non-ferrous industries, whereas the contribution of NH4+ (24%) was relatively high at the residential site. The levels of both ions (SO42- and NH4 +) were directly influenced by major wind directions. Natural ions (Cl-, Na+, and Mg2+) derived from the earth's crust and the ocean were prevalent in coarse particles. Based on this study, comprehensive monitoring of ions will be conducted in Ulsan.

To carry out a contamination assessment of trace metals in surface sediments from the Nakdong river main stream, surface sediments were collected at 15 sites and analyzed for trace metal content and grain size. The zinc, chromium and nickel (SH-01, SH-13) levels were characterized as “heavily polluted”, nickel and cadmium (SH-01) were categorized as “SEL” and nickel (SH-01) was determined to be at III level when compared with sediment quality guidelines (United States Environmental Protection Agency, Ontario Ministry of Canada, and National Institute Environmental Research of Korea). The enrichment factor and index of geo-accumulation results show that SH-01 has the highest level of anthropogenic contamination. In addition, according to the PLI, trace metals contamination was high at SH-01 (1.84) and SH-13 (1.07). The sediment from SH-01 was composed of comparatively coarse sediments compared to other sites but the metal contents were high, which is considered to be less related to grain size and more related to contamination by trace metals. The highest level of contamination (SH-01) in the study area is thought be due to the effect of mine tailings leaking in abandoned mines.

The automated measurement system for water quality analysis is customized. After the sample with the bar code is introduced on the conveyor, it is divided into the aliquot and the online measurement section. The system performs each for the sub-sampling of the original sample and the online measurement and data registration process of pH, turbidity, electric conductivity (EC) and total dissolved solids(TDS). For sub-sampling, a total of 17 group sample aliquots were carried out based on the criterion for drinking water quality test. In terms of precision and accuracy, the results confirmed that the statistically equivalent data between automation system and the human performances. The effectiveness of the automation equipment was evaluated by comparing the unit time of the aliquot and online measurement. For drinking water quality testing, 0.32 hour unit time were calculated by combining 0.17 unit hour per sub-sampling and 0.15 unit hour per online measurement. The cost recovery period, which takes into consideration the facility price is expected to take 1.8 to 2.8 years. The automation equipment is expected to play a role as a cooperative robot to help lab worker, because it will replace the sample management and the simple measurement if the installation cost is payable according to the built and assemble in domestic and increased demand in the future.

This study was carried out to investigate the contamination characteristics of emergency underground water supply facilities for civil defence at 1,076 sites in the south area of Gyeonggi-do from 2015 to 2017, and to provide basic data to establish the emergency underground drinking water policy. As a result, emergency underground water of 36.6% was unfit for drinking water standard, and thus 394 sites of total 1,076 sites exceeded the standard value. The unfit rate of bacterial contaminations such as total colony counts, total coliforms and fecal coliforms was especially high, and it showed the similar results to the other researches on the underground water contamination. In the results of correlation analysis, hardness had the highest positively correlation coefficient of 0.821 with chloride ion. The emergency underground water quality can be improved by the sustainable maintenance of regular pumping, installing UV radiation and preventing the contaminants such as microorganisms, nitrate, turbidity, organic, etc. from the surrounding environment.
