Workers who work at indoor and outdoor environment near busy road are suspected to be exposed to high-elevated air pollutant levels for workers (repairmen and polishers) pf shoe-stalls. Since shoe-stalls have particularly been located near busy road in Korea, workers might be high exposure to NO2 from traffic exhaust as well as indoor sources of shoe-stall such as portable gas range (butane gas) during working hours. In this study, we measured the ontdoor and out door NO2 concentrations of shoe-stall. Simultaneously, outdoor NO2 concentration of building though sidewalk from shoe-stall were measured. High NO2 exposure for workers of shoe-stalls was considered to be inflow of outdoor source of exhausted emission from vehicles and indoor source from usage of gas range to polish the shoe. Indoor/outdoor NO2 concentration ratio 1.06±0.34 in Asan, because usage of gas range was prevalent in Asan.

Water to provide for human use will be critical problem we face for next century and should be major branch of an earth science. It has been anticipated that consumption of water in Korea will have outstripped available resources before 2006. Already water shortage was reported in a tributary of the Nakdong river. Water supplies from downstream area of this river such as Pusan and Kyung-Nam, we heard, have become severely contaminated by human and industrial waste products. To solve these problem and make preparations for a waterway, we propose 58 dams located upstreams, whose storage of water amount to 1.4 billion tons. By these dams, fresh water can be obtained with small submerged area compared to the dams planned by government.

室內에 있어서 가스器具의 使用時間과 室素酸化物 曝露濃度와의 關連에 관한 硏究

손부순 순천향대학교 1992 논문집 Vol.15 No.3

實驗室에서 窒素酸化物 曝露濃度의 連續測定과 燃燒器具의 使用等, 生活行動時間 記錄을 實施하여, 相互關連을 統計的으로 分析하고, 그 結果로 부터 一般住民을 對象으로 한 生活行動時間 調査에의한 窒素酸化物 曝露量 評價의 可能性을 檢討하여, 다음과 같은 知見을 얻었다. (1)NO₂曝露量에 관해서는, 가스스토브 使用時間과의 相關이 높았고 NO₂曝露濃度 豫測에 대한 寄與도 가장 컸다. (2)가스곤로 使用時間은, 가스곤로에서의 窒素酸化物 發生量 크기에 비해, NO₂曝露農度 豫測에 대한 寄與가 적고 燃素器具에서의 窒素酸化物 發生과 거리에 동반된 曝露와의 關係는 燃燒器具의 使用狀況등에 影響을 받는것이 示唆 되었다. (3)NO曝露濃度는 가스곤로 가스스토브 使用時間과의 相關이 적었고 生活시間에 의한 曝露濃度豫側 은 困難했다. 따라서 生活行動個査에 의한 窒素酸化物 曝露量 評價를 考慮한 경우에는 NO와NO₂는 다른 시도가 必要하다고 생각된다. (4)生活行動時間에 의한 窒素酸化物 曝露量 評價의 誤差를 적게하고, 편견을 방지하기 위해서는, 個人모니터링 方法등을 倂用할 必要가 있다고 생각된다. ( ※이 論文은 東京都의 硏究지원을 받을 것으로, 東京大學 在學時 硏究 한 Data의 一部를 정리해 發表한 것이다.) We recorded the Livelihood time under the circumstances, those ate: using gas cooking burner and gas stove going out and in the experiment room and to ventilate by opening the window. While taking these time recordings, the dose of exopsure for nitrogen oxides (NO) to volunteer was continuously measured by the chemiluminescent NO/NO₂analyzer. In order to investigate the relationship between each activity and the exposure dose of ??, we applied statistical methods such as multiple regression analysis. After that we tried to consider the possibility of evaluating the exposure dose of ?? for general population based on daily activities by means of time budget survey. The results were as follows; (1)The statistically significant correlation was observed between the time of using gas stove and NO₂concentration (daily average), and ti also had the highest contribution ratio for predicting the dose of exposure for NO₂by muliple regression analysis. (2)The time using gas cooking burner was not markedly related to the does of exopsure for ?? (daily average), contrary to the amount of NO production. (3)It seemed difficult to predict the dose of exposure for NO by multiple regression analysis when independent variable was the time spent under each activity. (4)In order that different approach should be necessary to evaluate the dose of exposure for NO from the way which can be used in evaluating NO₂exposure, the most suggestive way to predict the dose of exposure successfully should be using a personal monitor along with methods above noted.

The prevalence of chronic respiratory symptoms was determined in 805 Residents 30 to 49 year of age in areas along major traffic arterials, in Tokyo Metropolis. Each resident was divided into three groups with respect to distances from the major arterials to household location. Some of chronic respiratory symptoms, that is, chronic cough, chronic phlegm, chronic wheeze, breathlessness, were reported more frequently among residents nearer to the road, these results suggest that exposure to automobile exhaust is significant risk in development of chronic respiratory symptoms.

손부순,염윤기,김종오,문정숙 한양대학교 환경및산업의학연구소 2000 環境과 産業醫學 Vol.9 No.1

This study's goale to find out the degree of the air pollution caused by vehicle emissions and to collect basic data for alternative plan in the improvement of the quality of the air by searching for the quality of the air around the road(in front of Chunan station, Terminal intersection, at Bangiugan five forked road, Chunanro intersection) in Chunan. NO2 and SO2 were measured as a object for this study in winter time and in summer time respectively. There has been an rapid increase in population and industrial complex has been built up in Chunan area. Therefore an increase in the number of vehicles and the use of domestic fuel has followed by that. So more studies of that and the effort for the improvement in the quality of the air will have to be made.

손부순 순천향대학교 기초과학연구소 1995 순천향자연과학연구 논문집 Vol.1 No.2

Personal exposure levels of NO₂for office workers and housewives living in A-San and neighboring prefectures were measured in two seasons with NO₂filter badge. NO₂concentrations in indoor and outdoor air in their offices and houses were also measured in the same periods. Personal exposure levels in winter ranged from 13 to 132 ppb and its distribution pattern was remarkably different from the other seasons (15.2-17.9 ppb). This fact suggests that use of heating appratus affects largely NO₂indoor air pollution in winter seasons. Actually, NO₂exposure levels of subjects used Kerosene heater (43.6ppb) and gas heater (33.4ppb) were higher than those of subjects unused heating apparatus (18.0ppb). Personal exposure levels of NO₂for man and woman living in the same houses were correlated well each other. The time spent indoors for office workers and housewives were both longer than 22 hour a day. Home staying time was about 60% of total indoor staying time for office workers and 90% or more for housewives. Personal exposure levels were significantly related to indoor exposure levels at home all seasons. Furthermore, personal exposure levels could be estimated from NO₂concentrations and staying times in various living environment.

The objective of epidemiology research is to analyze the relationship between outbreaks of disease and exposure to the specific risk factor. In this study, the assumption of the relationship between cause and effect and the definition of the confounding variable in the control group are designated. The study also implies the importance of assessing preliminary information at the initial step of research design.

大氣汚染 疫學에 있어서의 暴露評價에 대하여

孫富順,朴鍾安 서울大學校保健大學院 1995 國民保健硏究所硏究論叢 Vol.5 No.2

「Total Exposure」의 개념에 기초하여, 大氣汚染의 健康影響 關한 疫學硏究를 再構築한다고 하는 시도는, 아직 시작한 단계에 불과하다. 지금까지 實施된 疫學硏究를 이와같은 暴露評價의 点에서 다시 보는것도 必要할 것이다. 暴露와 影響의 關連을 檢出할 수 있다는 感度의 点에서는, sample size와 誤分類의 問題가 Trade-off관계에 있는 것에 충분한 留意를 해야 한다. 엄밀한 意味에서는 Individual Exposure를 測定할 수 있는 Technology의 開發을 推進하지 않으면 안되지만, 한편으로는 質的評價와 量的 評價의 조합에 의해서 暴露評價를 精密化해 나가는 길도 探索할 必要가 있을 것이다.

손부순 순천향대학교 기초과학연구소 1995 순천향자연과학연구 논문집 Vol.1 No.1

실험실내에서의 폭로 실험과 주방을 모방한 모델 실험에 의해, NO₂personal sampler의 性能評價를 실시한 결과, 다음과 같은 결론을 얻었다. (1) 이번 사용한 personal sampler에 의한 NO₂측정의 변동계수는 평균 10%이하였다. (2) NO₂의 측정한계는, 24시간 폭로 평균농도가 20ppb에서 200ppb, 혹은 이 이상이었다. (3) 이 sampler에 의한 NO₂1일 평균농도(폭로량)의 추정오차(90% 신뢰한계)는, 약 ±21ppb였다. An attempt was made to study the applicability of simple method of nitrogen dioxide measurement as a personal monitor usable in some field study. The device which we tested was a modification of so called simplified measurement method for NO₂using filter paper absorbed triethanolamine. We did two experiments, one was preliminary exposure experiment and the other was the experiment exposing the device under the circumstances like an ordinary kitchen. The coefficient of variation of the results of measurement of 24 hour exposure was less than 10% and the range of the results was from 20 ppb to 200 ppb. They showed a good linearity within the range above noted. By simple regression analysis between the measurement results by chemiluminescent method and that of the simple method, the error of estimation of the latter was about ±21ppb (confidence cofficient was 90%) According to these results, we believe that this simple measurement apparatus for NO₂can be used for the evaluation of personal exposure dose for NO₂.

손부순 순천향대학교 기초과학연구소 2004 순천향자연과학연구 논문집 Vol.10 No.2

In this study, 9 PC Rooms were selected to Assess the exposure to Indoor Air pollutants such as carbon monoxide(CO) and Total Suspended particulate(TSP). Indoor Air Quality of PC Rooms might be worse by smoking and vehicle emissions because the PC Room were generally located near roadway. Therefore, proper methods should be prepared to improve the indoor air quality in PC Room.
