  • 미세 먼지의 수용성 성분에 대한 On-line 방식의 측정 기기 개발의 필요성은 다음과 같다.첫째, 대기오염문제의 근본적인 물리, 화학적인 현상의 이해를 강화하는 데 있다. 미세 먼지의 화학적인 조성과 농도는 발생원에서 발생한 이후 급격하게 변화하는 대기환경 조건에서 빠른 변환( Chemical transformation )을 경험하는 데 현재의 필터 포집 측정 방식은 시간 분해도(time resolution)가 길어 현재의 측정 결과들은 정확한 미세 먼지의 화학적인 특성을 반영하기가 어렵다. (중략)

  • Micro dust is closely related to real life. Especially, the micro dust forecasting system is being implemented from February 2014. Reliability of data through air pollution monitoring network is important. The Ministry of Environment operates 506 air pollution monitoring networks (11 types) to analyze national air quality and establish air policies. However, there is not enough system to confirm and check the site suitability of the measurement site. Therefore, this study analyzes urban space using GIS. Assess the appropriateness and equity of air pollution measurement facilities. The final goal is to reflect the results of the analysis into the Seoul Metropolitan Air Pollution Monitoring Network Installation Plan.

  • The Japanese government's attempts to reduce fine particles (PM2.5) emission pollution in Japan have been largely ineffective. This is because PM2.5 in Japan originated from various sources including around half from oversea countries such as China. This prompts the Japanese government to start a new initiative to reduce PM2.5 at its origin by transferring local knowledge on air pollution reduction measures and technologies to China and working closely with the Chinese government. To promote further reduction in PM2.5, bilateral corporation between Japan and China should be extended to include Korea. It is recommended that an international convention should be in place to deal with transboundary air pollutants in East Asia. A successful East Asia corporation to reduce PM2.5 will not only contribute to clean air but also to future sustainable low carbon society in this region.

  • As one of the most serious health risk factors, air pollution can no longer be ignored. Particulate matter (PM) is an important and harmful component of air pollution that originates from a variety of sources. Numerous recent studies have linked PM to a range of conditions including cancer, cardiovascular, respiratory, and skin disease. The eye, despite being directly exposed to air pollution, has been investigated in very few of these studies. In this review, we describe the evidence from in vitro and in vivo studies, as well as epidemiological investigations, that supports the association between exposure to PM and the development of ocular conditions such as surface and retinal disease and glaucoma. Based on the results of previous studies, we suggest that PM exposure can lead to oxidative stress, inflammation, autophagy, and, ultimately, ocular surface disease. Nevertheless, almost no studies focus on ocular surface damage from PM while some epidemiological and clinical studies report on the posterior of the eye. However, the underlying pathological mechanisms in the posterior following PM exposure have yet to be identified, and further studies are therefore warranted of the ocular surface as well as the posterior part of the eye.

  • As society develops rapidly, environmental pollution is becoming a greater risk factor threatening human health. One of the major causes of air pollution that affects human health is particulate matter (PM), which contains a heterogeneous mixture of different particle sizes and chemical compositions. PM is classified by size into general PM (PM10; diameter below 10 ㎛) and fine PM (PM2.5; diameter below 2.5 ㎛). PM2.5 can pass through the respiratory tract into the circulatory system and thence throughout the body. PM2.5 is known to stimulate oxidative stress and inflammatory responses to cells, promoting diseases such as asthma, chronic respiratory disease, cardiovascular disease, diabetes mellitus, and immunological disorders. Although detailed molecular mechanisms for how PM stimulates disease progression still need to be elucidated, together with national efforts to reduce PM production, significant research has been conducted that demonstrates the harmfulness of PM in disease progression through in vitro and in vivo experiments. This review focuses on the harmfulness of PM in disease progression; we also introduce a biological verification method for determining the hazards of PM.

  • 본 투고에서는 2008년 환경부의 용역으로 실시된 "보육시설의 실내공기질 진단 및 개선 시범사업"의 결과를 바탕으로 우리나라 보육시설의 실내공기 오염 실태와 함께 개선방안, 그리고 개선효과에 대하여 소개하였다. 서울, 경기, 인천 지역의 61개 시설을 대상으로 실내공기질 측정과 설문조사를 실시한 결과 폼알데하이드와 총 휘발성유기화합물은 일부시설에서 "다중이용시설 등의 실내공기질 관리법" 기준치를 초과하는 것으로 나타났다. 반면 이산화탄소와 미세먼지는 조사 대상 시설 중 50 % 이상이 기준치를 초과하는 것으로 나타났다. 따라서 보육시설의 실내공기질 개선을 위해서는 각 오염물질의 발생원별로 유지관리 대책이 필요한 것으로 조사되었다. 또한 오염원인별 분석결과, 대부분 시설의 실외오염물질 농도가 실내보다 낮게 나타나 외기의 오염이 실내에 미치는 영향은 미비한 것으로 나타났으며, 계절에 따른 실내공기오염은 동절기에 낮은 외기온도로 인하여 실내를 하기 때문에 하절기에 비해 더 높게 나타났다. 공간에 따른 오염물질의 농도는 이산화탄소와 미세먼지의 경우 아동이 늘 상주하는 교실의 오염이 가장 심한 것으로 나타났으며 폼알데하이드와 총휘발성유기화합물의 경우 놀이실의 오염도가 교실에 비해 더 높게 나타났다. 개선방안별 개선효과에 있어서는 환기계획 몇 환기설비 설치, 지하공간 습기 문제 개선에서 가장 높은 효과가 나타났다. 향후 보육시설의 쾌적하고 건겅한 실내환경의 유지관리를 위해서는 보육종사자들이 활용할 수 있는 유지관리 지침 또는 매누얼에 대한 보급이 필요할 것으로 판단된다.

  • The fine dust generated in the home and restaurant business occupies a low ratio of about 4% of the total fine dust emissions. However, at the foodservice business, the rate of change of the pollutant concentration is very high, so that the temporary fine dust concentration can be measured up to 60 times. The pollutants generated from non-industrial combustion plants consist of particulate fine dust and gaseous organic compounds. To remove these pollutants, cleaning dust collection system, which is an effective system for simultaneous removal of gaseous and particulate matter, is applied. This is a method of increasing the probability of diffusion capture of the Brownian motion by pressurized liquid injection method using the atomizing nozzle. The dust removal efficiency of the fine dust collecting system was analyzed by nozzle spraying air pressure condition and angle using the manufactured fine dust removing system. As a result, it was confirmed that the efficiency of removal of fine dust and gaseous organic compounds was more than 90%. The developed system is expected to be highly usable in the future because it can remove particulate dust from the existing plant hood system without any installation cost.

  • 과거 10년전만해도 산업, 난방, 발전 등이 대기오염의 주된 원인이었으나 자동차의 증가로 말미암아 최근에는 자동차의 배기가스 즉 질산화물질(NOx), 일산화탄소(CO), 탄화수소(HC), 총먼지(TSP : Total Solid Particlate), 아황산가스(SO2) 등이 대기를 오염시키는 주요 물질이 되었다. 인구의 증가, 산업의 발달, 경제수준의 향상은 자동차 증가를 촉진시키는데 촉매제 역할을 해왔으며 대도시에서의 자동차에 의한 오염물질 배출량은 앞으로도 차량의 증가와 더불어 가속화할 전망이다.

  • In an advanced modern society, among air pollutants caused by urban industrialization and public transportation, fine dust flows into indoors from the outdoors. The fine dust meter used indoors provides limited information and measures the pollution level differently, so there is a problem that users cannot monitor and monitor the data they want. To solve this problem, in this paper, indoor air quality data fine dust and ultra-fine dust (PM1.0, PM2.5, PM10), VOC (Volatile Organic Compounds) and PIR (Passive Infrared Sensor) are used to measure fine dust. and a monitoring system were designed and implemented. We propose a fine dust meter and monitoring system that is installed in a designated area to measure fine dust in real time, collects, stores, and visualizes data through App Engine of Google Cloud Platform and provides it to users.
