        朱興珪,朴明述 조선대학교 환경연구소 1989 環境公害硏究 Vol.6 No.-

        This study analyzed a acid rainfall phenomenon through setting up a network of measurement at 31 sites around Chonnam and Chonbuk provinces from July to November of 1987. The results of this analysis are as follows. 1. There was little change of pH value classified by month. The distribution value was estimated within pH 5.2 to pH 6.4 at the whole investigated sites. 2. The pH value of site 23 was 5.0 to 5.2 during the whole investigated periods. The site had the lowest value in pH as well as in the variable value of measurement. Because it is adjacent to a big city, also it is under the influence of a seasonal wind (what is called a Monsoon), this is the result by a long distance transportation of the fine pollutants and gas state materials being discharge from the city. 3. Presenting pH 5.0 to pH 5.6 of site 21 is because of dropping of a short distance by rain out and wash out of fine particles and gas state materids being discharge from Iri Industrial Estate and Iri-city. 4. In the factory district and the Industrial estate, the acid ion density was low and lots of dust of soil were Showed because of an increase in the acid materials such as SO_(4). The acidity brought low in the site where largely comprised unpaved road and farm land. 5. Since, even if this investigated site is studded with many factorial districts, the district still comprises large farm land and forest land, dropping phenomenon of acid rain is on low side rather than others up to now.
