This paper was concerned with the investigation on the species of fungi detected in indoor environments. Mycological survey on the wall of buildings and houses in Seoul was performed from December 26, 1983 to February 11, 1984. The collected fungi with the sterilized cotton rod were cultivated and isolated in the Potato-Detrose Agar medium with chloramphenicol. The fungi detected in hospital were Cladosporium sp., Penicillium sp., Alternaria sp., Chaetomium sp. and others. The fungi detected in household were Penicillium sp., Alternaria sp., Aspergillus sp., Cladosporium sp., Rhixopus sp., Trichoderrna sp. and others. The kitchen of household was more contaminated by fungi than the living room and others. In hospital, it was much contaminated by the same species of the aboves on the wall of lobby and refectory. As the above results were recognized, the higher humidity and the more poor ventilation, the more species and amount of fungi were contaminated. Further studies on the identification of pathogenic fungi should be continued, The proper regulation for the hygienic maintenance of indoor environment in household, hospital and other public buildings should be recommended as well.

This study was carried out to investigate air pollution by total suspended particulate(T.S.P.), benzene soluble matter and benzo(a) pyrene in Seoul city. The sampling areas were divided into commercial(Kwang Hwa Moon), indus-trial(Ku Ro Dong) and residensial area(Shin Chon). Sampling was undertaken by High Voulme Air Sampler for four seasons from January 1917 to November 1977. The T.S.P. was extracted with Soxhlet apparatus by benzene and benzo(a) pyrene was separated by column chromatography and thin layer chromatography. The concentrations of benzo(a) pyrene were measured by means of fluorophotometer, and following results were obtained. 1. Arithmetic average concentration for 1-day averaging time of total suspended particulate were $275.6ug/m^3$ in Kwang Hwa Moon, $325.9ug/m^3$ in Ku Ro Dong and $193.0ug/m^3$ in Shin Chon. 2. The seasonal variance of total suspended parti-culate at Ku Ro Dong and Shin Chon were $102.7ug/m^3\;99.6ug/m^3$ respectively and at Kwang Hwa Moon $39.9ug/m^3$. And the concentration of autumn is higher than of that spring at Ku Ro Dong and at Shin Chon, but at Kwang Hwa Moon, the seasonal variance is very little. 3. The concentrations of 50% frequency from geometric mean for 1-day averaging time were $264ug/m^3,\;300ug/m^3\;and\;178ug/m^3$ at Kwang Hwa Moon, Ku Ro Dong and Shin Chon. And geometric standard deviation were 1.27, 1.38 and 1.41 respectively. 4. The concentrations of benzene soluble mater were $26.9ug/m^3$ at Kwang Hwa Moon, $22.7ug/m^3$ at Ku Ro Dong and $15.5ug/m^3$ at Shin Chon, and the ratios to the T.S.P. were 9.8%(range 5.6-14.8%), 7.0%(range 2.4-14.4%) and 8.0%(range 5.5-22.1%) respectively. 5. The concentrations of benzo(a) pyrene were $8.5ug/m^3$ (range $0.8-29.9ug/m^3$) at Kwang Hwa Moon $10.9ug/m^3$(range $1.1-52.0ug/m^3$) at Ku Ro Dong and $5.8ug/m^3$(range $1.5-11.4ug/m^3$) at Shin Chon. 6. The results of this investigation were relatively high in compared with the recommended standards of suspended particulate in air of U.S. Environmental Protection Agency and observed levels of benzo(a)-pyrene in U.S. city.

The pinus trees planted by the road in the Seoul -Suwen high-way was surveyed on the damages due to air pollution during April and May in 1984. The results were as follows ; The concentration of SO$_2$was ranged from 0.003 to 0.05ppm, NOx from 0.03 to 0.1ppm and the amount of dust fall, from 10 to 110ton/km$^2$/month. While the concentrations of gaseous pollutants such as SO$_2$and NOx were notsignificantly different in the type of road and with in the distence of 20 meters from the road the dust falls were decreased as remoted from the road. The tissue damages of leaves were determined by the microscopic observation. The higher concentration of dust fall on the leaf, the more severe damage observed in the stomata. The attached dust of the leaves were ranged from 1l to 75mg/g of leaf, and those were significantly incereased as near from road. The sulfur contents of leaves were measured at 0.15g/100g of leaf in the 5 meters located and at 0.064g/100g of leaf in the 20 meters, and the lead contents, 45ug/g of leaf in the 5 meters and 24ug/g in the 15 meters. The appearent damages of plant were very much corelated to the attached dusts of leaves the sulfur contents and the amount of dust fall, and the multiple regression analysis between the damages and factors of air pollution were under taken. As increment of vehicle in future, the air Pollution was predicted and the plant damages were estimated.
