The studies on the actual state of poilution components of various indrstrial wastes were conducted on order to procide the methods for the economic and efficient treatment of industrial waste water for the prevention of public nuisance and some laboratory studies were carried out on the treatment of polluted water using sand filter bed, aerator and sedimentation method. The results obtained are as follows: 1. The results of analysis of industrial waste water showed high pollution of B.O.D. with 105.0ppm and Chloride with 47.0 ppm in Textile Factories. 2. The results also showed high pollution of solids with 2,150 ppm in Lumbering Industries. 3. Because of the serious problem on the public water resources due to the discharge of tremindous amount of industrial waste water, the best and economic method on the treatment of indrstrial waste water from large scale of factories seems to be the Sand Filtration Method.(Removal rate for overall was 60.4%)

This study was conducted by the Dept. of Preventive Medicine, Kyung Hee University, School of Medicine from 2, August to 12, August, 1971 for grasping the actual pollution state of well water and eliminating the sources of pollution in a rural area. A total of 36 wells scattered around Won-Sung Kun, Kang-Won Province were examined physico-chemically and bacteriologically and the following findings could be obtained: 1) It is considered that water source itself is very fine but the surroundings of wells result in water pollution. 2) Bacteriologically, only 10% among them were within the approved limits. 3) Physico-chemical examination revealed all of them were polluted.

This study was conducted by the Dept. of Preventive Medicine, Kyung Hee University, School of Medicine as a preliminary test for the effects of Fluorine Compounds to the Plants from April through August, 1971. Fluorine was measured with Zirconium-Alizarine method and the following findings could be obtained: 1. Most high densities (25.7 pptm) was found around the industrial areas and lowest (19.3 pptm) around residential sections in Seoul. 2. Average density of Fluorine in the atmosphere of Seoul City was 22.3 pptm which can damage such plants as Pine, Strawberry, Peach and Grapes. 3. Fluorine contents (22.3 pptin) in Seoul area atmosphere shows about 4 times more than that of Cincinnati, Ohio, U. S. A.

An experimental study of carbon monoxide concentration in air of the restaurants(total 50) and carboxyhemoglobin saturation of workers(512) who were working in the restaurants was conducted by the staffs of the Dept. of Preventive Medicine from November 1970 to December 1971. Carbon monoxide concentration in air was measured with Kitagawa CO detecting tube and carboxyhemoglobin saturation in the blood of workers was measured by The expired air analysis technique following Dr. Breysse and Gabay. Each worker was asked to inhale and exhale deeply prior to commencement of the test. They were then requested to inhale and hold their breath for approximately 20 seconds after which they were instructed to exhale "normally" then to blow the remainder of the breath into a balloon. This expired air was then immediately examined with the Kitagawa tube and carboxyhemoglobin saturation was calculated from the following regression relationship: COHb%=0.5+(CO ppm/5) The findings and results obtained were summarized below: 1. The mean CO concentration in air of restaurants of Class A, where only propane gas was used for fuel, was less than 50 ppm and the mean COHb saturation in the blood of workers was 7.5% in summer and 8.1% in winter. 2. The minimum concentration of CO in air of the hall of Class B restaurants where used gas was 96.5 ppm during summer and maximum concentration was 180.3 ppm in the kitchen during winter. And the COHb saturation was 12.5-17.1% which could initiate the slight CO poisoning. 3. In the restaurants of Class A where charcoal was used for fuel, the air contained 83.5-144.8 ppm of carbon monoxide and the COHb saturation in the blood of workers was 11. 1-15.4% which could cause slight symptoms of CO poisoning. 4. Mean concentration of CO_ in the B or C graded restaurants where charcoal was used, was 265 ppm and the COHb saturation was as high as 20% which could cause moderate CO poisoning to the workers. 5. Even in the summer, so called wine shop where coal was used for fuel contained more than 124.3 ppm of CO and in the winter it contained 221.5 ppm. Among them we could find some contained as much as 350 ppm of carbon monoxide in air. The mean COHb saturation in the blood was 21.4% which could cause moderate symptoms of CO poisoning. 6. Highly significant correlation was found between the COHb saturation and the concentration of CO in air of restaurants.

Mountain Wells are very important water source for the most of the climbers in Seoul area. But the facilities around the wells are not modernized to prevent from contamination of microorganism and the other pollutants. We focussed our intention on the detection of some harmful chemical ingredients and contaminants. A total of 58 wells were examined according to the Standard Methods(APHA) and the following results were obtained: 1) Among the examined 58 wells, only 10 wells were adequate to the drinking water standard, 2) 7.9mg of liberated $CO_2$ was found in the Tchun-Ho-Dong Mineral Well, 3) Chemically harmful ingredients were not found, 4) The Mountain Wells were contaminated by Coliform groups as many as 18 times than rural wells.
