Objectives: The purpose of this study is to evaluate the characteristics of leachate discharged from livestock burial sites in Gangwondo resulting from foot-and-mouth disease by monitoring the water quality at the survey tube-wells installed near livestock burial sites in order to investigate the effect of the leachate on the quality of nearby underground water and suggest a water pollution level in accordance with water quality evaluation criteria. Methods: To minimize the secondary environmental pollution damage caused by leachate at burial sites of livestock killed by foot-and-mouth disease, this study analyzed the leachate directly discharged from burial sites and installed survey tube-wells within 300 meters of livestock burial sites and investigated water quality as a means to ascertain the environmental effect of the leachate from the burial sites. In accordance with environmental management guidelines on livestock burial sites, this research investigated the water quality in the survey tube-wells in fifty five burial sites in Gangwondo. The elements investigated were $NH_3$-N, $Cl^-$, $NO_3$-N, conductivity, and E. coli. Water quality was monitored from 2011 to 2013. Results: The water quality from the drain pipe at the location of leachate from livestock burial sites showed BOD 37,209 mg/L, COD 8,829 mg/L, $NH_3$-N 3,633 mg/L, and $Cl^-$ 580 mg/L. According to the monitoring results of water quality ($Cl^-$, $NH_3$-N, conductivity) at the survey tube-wells, there was suspicion that 13 out of 55 burial sites discharged leachate, five sites discharged highly concentrated leachate (13%): one in Gangneung, one in Wonju, and three in Cheorwon. Conclusion: It was judged that out of thirteen observation wells which showed a possibility of discharged leachate, three survey tube-wells have established the discharge effect of leachate at burial sites up to recently. Therefore, it is judged that it is necessary to continue monitoring them and devise additional measures.

Due to the stringent drinking water quality, formaldehyde will be included in Korean drinking water standard from year 2014. However, its standard analytical method has not yet been established. This study compares two analytical methods, DNPH-LC and ACFAS with respect to their analysis principles, Method Detection Limit (MDL), Limit Of Quantitation(LOQ), precision, accuracy, reproducibility, convenience, number of samples analyzed per hour and analysis cost. These methods measure absorption intensity at 360 nm by using HPLC after DNPH-derivatization (DNPH-LC) and at 410 nm by using Automated Continuous Flow Absorption Spectrophotometer (ACFAS), respectively. Reproducibility was tested by repeating the analysis 7 times using a standard solution for each method. For DNPH-LC method, MDL was 0.5 ㎍/L, LOQ was 1.58 ㎍/L with standard deviation of 0.16 ㎍/L. For ACFAS method, they were 0.27 ㎍/L, 0.85 ㎍/L with standard deviation of 0.09 ㎍/L, respectively. Both methods satisfied the requirement set by the Korean drinking water quality standard. Complexity of sample pretreatment procedure for DNPH-LC method may cause large error and, consequently, the analytical result will depend on the level of skill of analyst. In contrast, ACFAS method which used only one reagent equipped with an automated injection device showed little analytical error. It costs about $5.00 and $1.00 for one sample to analyze by the DNPH-LC method and the ACFAS method, respectively. Compared to the DNPH-LC method, ACFAS method provided more reliable analytical results. In terms of convenience, easiness and analytical cost, ACFAS method was demonstrated to be superior to the DNPH-LC method. The results of this study suggested that the ACFAS method could be adapted as a proper method for determining formaldehyde content in drinking water.

This study was to evaluate the genotoxic effects of airborne particulate matters using single cell gell elec trophoresis (comet assay) in A549 human lung carcinoma cells. The total suspended particulate (TSP) was collected on back-up filter in Chuncheon, Kangwon Do, South Korea from April, 2003 to February, 2005. The concentrations of TSP, B(a)p and most of heavy metals seemed to be higher in spring and winter, and lower in summer. And they showed higher concentration in the commercial areas and the residential area having more traffics than in the rural area. It was found that A549 cells interacting with the organic extract of TSP showed more DNA single-strand breaks compare to untreated cells. The genotoxicity of the organic extract of TSP was increased with the pre-treatment of S-9 mixture during the culture or with the treatment of endonuclease after cell lysis. The DNA damage by the organic extract of TSP was higher in winter and the commercial area than in summer and the rural area. This study suggests that TSP, heavy metals and B(a)P analyzed showed significant variation depend on the seasons and the areas which are correlated with the DNA damage evaluated by Comet assay, indicating that genotoxic biomarker is useful for toxicological evaluation of air quality.

본 연구에서는 토양환경보전법에 따라 정부에서 매년 수행하는 토양오염실태조사 과정에서 GIS의 적용 가능성과 필요성을 분석하였다. 이를 위해 토양오염조사의 계획단계, 표본조사단계, 결과분석단계에서 공간분석 도구인 GIS의 활용가능성을 살펴보았다. 강원도에서 2010년부터 2012년까지 3년 동안 수행된 604개 지점을 대상으로 GIS 기반의 분석을 수행한 결과 조사지점의 공간적 집적 정도는 3년 간 자료를 통합하였을 때, 1년 단위의 자료보다 높게 나타났다. 이는 조사지점 선정을 위한 계획단계에서 공간분포에 대한 고려가 필요함을 의미한다. 표본조사단계에서는 현재 주소나 평면직각좌표로 기록되는 위치정보의 오차와 오류를 최소화하기 위해서 GPS를 활용한 경위도 좌표를 추가하여야 한다. 이는 효율적인 자료 관리와 GIS 등을 활용한 정밀한 공간분석을 위해서도 필요하다. 마지막으로 결과분석단계에서는 토양오염결과를 GIS를 이용하여 지도화함으로서 정보 전달과 의사결정의 효율성을 높일 수 있고, 공간상에서 도로와 하천 등 토양오염과 영향을 주고받는 요인들과의 관계를 분석함으로서 추가적인 정보를 얻을 수 있다. This study relates to the need for GIS in the soil contamination survey which is performing annually in Korea, accordance with the Soil Conservation Act. To do this, we had explored the potential use of GIS in the each phase of planning, sample survey and results analysis of soil contamination survey. Soil contamination survey of 604 samples, which were carried out in Gangwon-Do from 2010 to 2012, were analyzed by GIS. The level of spatial clustering of three years cumulative data was higher than that of one year's data. This means that the spatial distribution of survey points should be considered in the planning phase. In addition, survey points should be recorded as latitude and longitude coordinates by the GPS, because to record the site with the address or the plane coordinate is likely to cause error. This is also need for the efficient data management and precise spatial analysis. Finally, the result of soil contamination is mapped in order to improve the efficiency of communication and decision-making. From these mapa, we can find additional relationship of the other factors like roads and rivers which relate to soil contamination.

In this study, we confirmed that the pesticides flow out into streams during rainfall by the way of helicopter spraying. The maximum concentration was 23 pg·mL-1 and the distribution of concentrations showed similar to the normal distribution. The runoff characteristics of insecticides using helicopter spraying was affected by the elapsed time of the start from spraying until rainy days and rainfall intensity. The pesticide concentrations of sample ranged from 0.65 to 3.04 pg·mL-1. Fish kill did not occurred in the stream and the lake cause of the pesticides runoff. Aquatic animals, such as Orthrias toni, Rhinogobius brunneus, tadpole etc. were still alive in the stream. It indicates that this class of pesticide does not cause toxic to fish by runoff event. However, the honey bee kill event was reported in the spray region during the helicopter spraying period. The further study such as ecotoxicity test is needed to reveal the pesticides effect reach to the ecosystem.
