In our country, the Ministry of Health and Social Affairs adopted the WHO standard from December 1993. However, the standards have not been monitored carefully throughout the province and there is little research on the effects of aluminum on people's health and management of cleaning bed. In this research, we measured Al in raw and treated water of major cleaning beds of chonbuk province and got the situation of contamination. The results are summarized as follows; 1. The range of the aluminum concentration in row water is from ND(non-detected) to 0.08㎎/ℓ, to average is 0.03㎎/ℓ, and it is the highest figure at 0.08㎎/ℓ in Wal-Iock bed of Nam-Won district. 2. The major concentration extent from ND to 0.009㎎/ℓ, ranks 35% and its average is 0.07㎎/ℓ. 3. When we analyzed the aluminum concentration over the passage of time, we found a lot of A1 in samples that were taken from P.M 10 to A.M.I. 4. There are no samples exceed 0.2㎎/ℓ which is the drinking water standard of WHO. 5. It is revealed that the average concentration is 0.15㎎/ℓ in big cities whose population supplied water is more than 500,000. 6. Investigating the effect on the coagulant, we knew the factors that the residual Al concentration. In the place where no coagulant was used Al concentration is 0.04㎎/ℓ on the average. The ones using the aluminum sulfate and activated carbon is 0.09㎎/ℓ on average. So the one using Al_2(SO_4)_3 is 0.11㎎/ℓ on average. 7. The concentration fluctuate with the seasons : Jenuary is 4 times as much as July. 8. It is also connected with the other water pollution the consumption of KmnO_4, NO_3-N, SO_4^2- ect.

The purpose of this study is to estimate the spatial distribution of atmospheric pollutants due to the structure near the street. Especially, transport mechanism in complex area at the midtown district with the lofty buildings is complicated. So this study estimates spatial distribution of atmospheric pollutants according to the height of the building and the distance from the street. The results of this study are as follows. 1. If the building is stationed in the flat area, the flow of air mass near the building changes. The changing range of air flow is varied with the height of a building and the arrangement of a building. 2. The spatial distribution of atmospheric pollutants varied with the height of building. However, this rate of variation decreases with the increment of height. 3. The accumulation of atmospheric pollutants is higher at the front of the building than the rear of the building. This phenomenon is, however, reversed according as the structure becomes more distant from the street. 4. The highest concentration appeared at a distance from the front of the building in case of high building. 5. The concentration near the structure is decreased with the downwind direction. However the change is small. 6. The wind speed doesn't affect the spatial range of the high level concentration but has an effect on the concentration.

The effective methods of phosphorus removal in the small scale or large scale of sewage disposal plant were: 1) biological method [anaerobic oxic system, activated sludge (removla rate, 20-30%)] 2) flocculation by coagulants [FeSO_4, Al_2(SO_4)_3, poly aluminium chloride] 3) recrystallization by hydroxy apatite 4) Ca(OH)_2. But the ability of phosphorous removal was certified in mineral pyrite, which is a new method. And the ability was compared with other removal methods. In the 0.002% of Na_3PO_4 solution, contacting with mineral pyrite for 20 minutes, the removal rate became 90%. Mineral pyrite reacts neither strong acids nor NaOH alkali solution, but adsorbed Na_3PO_4 is easily solubed to acid, 2% H_2SO_4. When mineral pyrite became a critical point by adsorbed phosphorous, if the adsorbed phosphorus was washed out, and was treated with saturated Ca(OH)_2 solution, the ability of phosphorous removal is regenerated. It is useful and effective to remove 90% phosphorus of 0.002% Na_3PO_4 solution in 2m height of pyrite column, at 100ml/minute flow rate. Phosphrous concentration of Kumkang is low at the upper stream and high at the down stream. COD, SS and phosphorous concentration of the tributary rivers are very high, especially, the plentiful algae and foul smelling were easily certified at Kap-Chon and caused the eutrophication of main river. Therefore, the pollutants must be completely removed at the sewage disposal plants near cities.

Recently, it is increasing of environmental impact assessments by government, private enterpsises, widen streets and pavement works, etc. The methods of air pollutional impact assessment for the enterprises were found many defects to be improved. The enterprises named A, B, C, D, E, F, G, and H were examined, as follows. 1. It is a rule to measure or survey on every season a year, but practical measurement in the assements were only 2 times or 3 tines. 2. Every assessment was mistaken annual average for average of 24 hours 3. By making use of simulation model, it must be examined for the adequateness, by the method of the correlation coefficient and percentile. Most of the assessments were simulated the pollution without examination for the adequateness. 4. It is not proper to use the simulation for the total suspended particulates by EPA formula, it must be studied for new simulation formula that is suitable to Korean working conditions.

Jeonbug area is an ideal place for produciug Korean handmade paper, and has a long history of it, There used to be more than 70 plansts, but only 45 of them are at present being operated. Plants operated on a small scale produce paper as a subsidiary work of farm families during the season free. Recently the export of Hwaseunji(Korean handmade artistic paper) and the increase of the demand of the paper in the country have revitalized. The results of the investigation of their location, the continuity of their preperaion, their facilities and the like are as follows 1) Of 74 plants, 20% are located in Jeonju city, and 32% in Wanju district. 2) The plants in Jeonju city and Wanju district produce Hwaseunji, whereas those in the other districts produce sliding screen paper, poor quality paper made of mulberry bark, and Hwasenuji. 3) The bark of the paper mulberry as raw material is to be cooked for 2-3 hours with 10-13% of NaOH or Na₂CO₃etc 4) As the utilization of waste vellum paper rapidly increase in quantity, its amount comes to 50% of materials. As a result it has now become main material. 5) The production amont of paper mulberry was 617_M/T in 1976, and its consumption amount was some 407_M/T. 6) It is advisable to leave alone the cooked bark of mulberry for 5-12 hours. 7) It is advisable to treat waste vellum paper with 15-20% Na₂CO₃. 8) The storage liquid of Abelmoschus manihot medic root is used with the mixture of 2% formaline or 1.5% formaline and 1% CuSO₄·5H₂O. 9) It would be better to see a mixture of 0.02% HgCl₂, 0.1% formaline and PAM for the prevention of decreasing viscosity. 10) In manufacturing sliding screen paper, it is advisable to increase the proportion of the bark of paper mulberry and to revive its originl quality of Korean handmade paper. 11) The output of korean handmade paper in Jeonbug area amounts to Won 53,100,000 in the former half of the year 1977(January-June). 12) Plants operated on a larger scale must be encouraged to be equipped with hollander beater and produce Hwasenuji.
