Abstract
[한글]

産業發展과 人口의 都市集中化등에 의하여 資源의 消費가 增大하므로서 大氣汚染物의 排出量도 增加하게 된다. 따라서 汚染源에서 排出되는 汚染物의 影響을 豫測하고 이에 따른 防止對策을 樹立하기 위해서는 大氣汚染度에 對한 事前 豫測評價가 要求된다. 大氣汚染度에 의한 長·短期的 影響을 豫測評價하기 위해서 미국의 EPA에서는 擴散모델들을 勸奬하고 있으나 이들의 適用에 따른 妥當性은 아직 우리나라에서는 檢討가 미흡한 실정이

다.

本 硏究는 가우시안 모델의 一種인 AQDM(Air Quality Display Model)을 利用해 한 工業都市를 對象으로 工業都市의 環境基準 및 大氣汚染 管理對策을 樹立하는데 도움이 되도록 大氣中 亞黃酸가스와 浮遊粉塵의 季節別 年別 平均汚染濃度를 豫測評價하고 모델의 妥當

性 與否를 檢討하였다.

入力資料로 汚染物 排出量調査와 氣象條件은 中央觀象臺 資料를 使用했으며 汚染濃度의 推計를 위한 Computer로는 IBM社의 IBM PC를 使用하였으며 다음과 같은 結果를 얻었다.

1. 硏究對象 地域에서의 實測値와 같은 條件下에서 算出된 推計値와의 相關係數(r)은 亞黃酸가스가 0.64, 浮遊粉塵은 0.75였다.

2. AQDM에 의한 推計値는 1984年에 浮遊粉塵은 最大濃度가 봄 272.3 ug/m**3, 여름 160.3 ug/m**3, 가을 219.7 ug/m**3, 겨울 299.9 ug/m**3, 亞黃酸가스는 最大濃度가 봄 0.148 ppm, 여름 0.121 ppm, 가을 0.12 ppm, 겨울이 0.141 ppm으로 推計되었으며 環境保全法

의 年平均 環境基準値를 超過하였다. 1986年에 浮遊粉塵은 最大濃度가 봄 275.7 ug/m**3, 여름 168.9 ug/m**3, 가을 231.5 ug/m**3, 겨울 303.4 ug/m**3, 亞黃酸가스는 봄 0.154 ppm, 여름 0.126 ppm, 가을 0.125 ppm, 겨울 0.184 ppm으로 推計되었으며 環境保全法의 年平均 環境基準値를 超過하였다.

(Directed by Prof. Sook Pyo Kwon, D.P.H., Ph.D.)



Industrial growth, economic development, and increase in energy conversion,

together with the city-ward tendency of the population have seriously deteriorated

the air quality especially in metropoles and industrial estates. And so, Impact of

pollutant that have been released from emissin sources predict and to consider a

preventive-measure required pre-prediction-evaluating for air pollution.

For the purpose of prediction-evaluating ambient air quality level environment

impact assessment, U.S.EPA encouraged evaluation model but validity is not

considered in Korea.

This research is considered validity of model and to permit simulation of

seasonal, year averaged concentration of an air pollutant, in total suspended

particulate, sulfur dioxide for a industrial city in 1984, 1986, using Air Quality

Display Model which is a kind of Gaussian Models.

Input data included source pollutant emissions, source configuration and

location, meterological data expressed as a relative frequency distribution of wind

direction, wind speed, air stability. And IBM/pc made by IBM Co, was used for the

predictive concentration.

The major results are as follows;

1. Predictive value by Air Quality Display Model and observed value in a same

condition of research area which is correlation coefficient(r) is 0.64 in sulfur

dioxide, 0.75 in total suspended particulate.

2. The predictive value by Air Quality Display Model would exceed 0.05ppm which

is Environmental Air Quality Standard(Annual) of sulfur dioxide in industrial area

and 150μg/m**3 which is Environmental Air Quality Standard(Annual) of total

suspended particulate in industrial area, 1984, 1986.
