  • 전기철도가 운행될 때 발생하는 전자계 환경문제에는 주변의 근거리 및 원거리 전자계 및 시스템 내외부에서 발생되는 과도성 이상 전압 등이 포함되는 태 이들은 다른 전기 기기나 인체 영향을 미치게 된다. 이중 특히 철도 내부 및 외부의 통신이나 제어기기에의 영향은 열차의 안전성과 연결이 되어 중요한 사안이 된다. 이러한 문제외에도 우리나라 전력계통의 건설이 요즘 들어 많은 인원을 겪게 되는 것도 날로 증가하는 전자계 환경에 대한 민감한 관심 때문이라 하겠다. (중략)

  • 스모그는 대기오염으로 인해 나타나는 대표적인 오염 현상이다. 스모그는 시정을 감소시키고, 눈ㆍ코ㆍ호흡기 등을 자극하여 인체의 건강에 나쁜 영향을 미친다. 스모그 현상은 주로 바람이 약하고 지표부근의 기온이 역전하는 특정한 기상상태에서 대기 중 가스와 입자간의 반응에 의해 여러 경로론 거쳐 생성된 에어로졸이 증가하여 나타난다. 최근 자동차 수의 급속한 증가와 휘발성 유기화합물질 (volatile organic compounds, VOCs)의 사용으로 인하여 서울 지역에서 스모그가 발생하는 빈도가 많아지고 있다. (중략)

  • An environmental survey from three abandoned metal mine areas was undertaken on to assess the risk of adverse health effects on human exposure to heavy metals influenced by past mining activities. Tailings contained high concentrations of heavy metals may have a impact on soils and waters around the tailing piles. In order to perform the human risk assessment, chemical analysis data of soils, rice grains and waters for As, Cd, Cu and Pb have been used. The HQ values for heavy metals via the rice consumption were significantly higher compared with other exposure pathways in all metal mine areas. The resulting HI values in three mine areas were higher than 9.0, and their toxic risk due to rice ingestion was strong in these mine areas. The cancer risk of being exposed to As by the rice consumption from the A, B and C mine areas was $5.1\;{\times}\;10^{-3}$, $6.8\;{\times}\;10^{-3}$ and $3.1\;{\times}\;10^{-3}$, respectively. The As cancer risk via the exposure pathway of rice ingestion from these mine areas exceeds the acceptable risk of 1 in 10,000 set for regulatory purposes. Thus, the daily intakes of rice by the local residents from these mine areas can pose a potential health threat if exposed by long-term As exposure.

  • Water quality standards (WQS) are mandatory to guarantee the human health and protection of aquatic ecosystems, and maintain the condition of suitable water quality. The present WQS for the protection of human health in Korea contain nine substances (As, Cd, $Cr^{6+}$, CN, Pb, Hg, ABS, organophosphorus compounds and PCBs), but it is insufficient to preserve the human and aquatic ecosystem from a variety of chemicals. Therefore, it is necessary to expand the substance of WQS for the protection of human health. In this study, we chose the 20 chemicals from 43 chemicals of the project entitled 'Development of Integrated Methodology for Evaluation of Water Environment'. The methodology for calculating water quality criteria was amended from the US Environmental Protection Agency (US EPA)'s equation for deriving ambient water quality criteria for the protection of human health. The factors including fish intake, drinking water intake, and human body weight used in the equation reflected Korean situations. The monitoring values were derived from the water quality monitoring data in Korean four main rivers. The orders of priorities of chemicals were evaluated by human health risk assessment, and the proposed WQS was derived by technical and economic analyses. These results were reflected to expand the WQS for the protection of human health.

  • In January the clo-values show two characteristic patterns on the insulation, Samjiyon has the highest clo-values while Changjon has the lowest in North Korea, and the coastal areas are lower than in the interior areas. This regional difference is a result of predominant temperature, wind speed and orographic effects. Particularly, in August the coastal areas are generally lower than the interior areas because of orographic effects(wind direction, wind speed). All regions except Samjiyon legions and northern interior regions have low values during the period from the early August to the middle of August. These are largely derived from the stable weather with the highest temperature, humidity and strong radiation by the North Pacific Anticyclone appears in Eastern Asia.

  • Vinyl chloride (VC) is a known human carcinogen, and it is released to multi-environmental media via several exposure routes. VC was potentially evaluated as a water quality pollutant based on human health risk assessment in Korean water environments. In this study, we investigated physicochemical and toxicological properties of VC, human health and ecological risk assessment, and the regulation of VC as a water quality pollutant in developed countries. Currently there are no standard or guideline values of VC in Korean legal system for the protection of human health and aquatic ecosystem, except that it is designated as a specific toxic substance and a water quality pollutant. Human health risk assessment of VC was previously performed based on the limited water quality monitoring data. The monitoring level of VC in Korean water system is more higher than other countries'. VC was assessed as potential hazardous chemical based on the US EPA's cancer risk assessment. There were a few ecotoxicity data of VC available using very limited kinds of aquatic organisms, and the toxicity results obtained seem to be overestimated without considering the losses of VC in open exposure system. Therefore it is needed to monitor the VC in various areas and to carry out the ecotoxicity research using multi-level organisms. We expect that these results can be useful information for implementing VC as a water quality pollutant in legal system for the protection of human health and aquatic ecosystem in near future.

  • To provide the research strategy for protection of children's health from hazardous chemical, we reviewed the hazardous chemicals can be exposed through maternity, children's life style and living environment. Recently, diseases related with children's living condition were focused as asthma, atopy, childhood developmental disability, congenital malformations and obesity. Children can be exposed to hazardous chemicals through an ambient air, water, soil, food, toys and other factors such as floor dust. Also children's health was deeply related with a wrong life style and neglectful caring by a lack of knowledge and information of harmful ones at parents and child care center's nursers. According to the previous study, the chemical risk factor of children's health were identified as inorganic arsenic, bisphenol A, 2,4-D, dichlorvos, methylmercury, PCBs, pesticide, phthalates, PFOA/PFOS, vinyl chloride, et al. Domestic studies for identification of causality between children exposure to chemicals and resulted hazardous effects were not implemented. The confirmation of chemical risk factors through simultaneously performing toxicological analysis, human effect study, environmental/human monitoring, and risk assessment is needed for good risk management. And also, inter-agency collaboration and sharing information can support confirming scientific evidence and good decision making.
