- In order to assess the degree of atomospheric pollution and noise and to contribute the health improvement of residents in Pusan, the author measured the levels of CO, SO2, NO2, TSP, HCHO and noise in 8 areas(industrial, residential and park areas) from January to March in 1990. The results were as follows: 1. Sasang industrial area was significantly higher (2.85 +/- 0.84ppm) in the average concentration of CO than other areas. However, there no areas to affect the human body in terms of CO concentration. 2. In general, industrial area was significantly higher (0.134 +/- 0.084ppm) in the average concentration of SO2, than other areas, and it was the lowest (0.009 +/- 0.005ppm) in the Namchon-dong area. 3. Industrial (0.033 +/- 0.009ppm) and residential area (0.029 +/- 0.004ppm) were significantly higher in the average concentration of NO2 than Park area (0.009 +/-0.001ppm). However, there were no areas to affect the human body in terms of NO2 concentration. 4. Sasang industrial area was the highest (580.4 +/- 415.26 microgram/m3) at the average concentration of TSP and Hae-Un Dae area was the lowest (97.22 +/- 37.86 microgram/m3). But TSP concentration showed the level to affect the human body in most areas. 5. Industrial area was significantly higher (2.25 +/-1.15ppb) in the average concentration of HCHO than residential (1.13 +/- 0.25ppb) and park area (1.33 +/- 0.20ppb). 6. Industrial area was significantly higher (77.28 +/- 6.92dB(A)) in the level of noise than residential (65.77 +/- 3.76dB(A)) and park area (64.65 +/- 5.25dB(A)). In comparison with regional Standard Noise Level, however, the average noise level of residential and park area was higher than that of the Standard. In general, the level of pollution of industrial complex areas was relatively higher than those of residential and park areas. Among the industrial areas, sasang area was worst in most items. Both SO2, and TSP showed the level to affect the human body in most of studied areas. It is necessary to install a new Air Quality Standard for HCHO to screen our environmental pollution.

Abstract
PDF
- The paralytic shellfish poisoning was occurred among 25 laborers who worked at breaking-up of ships in Pusan for 5 days from March 29 to April 2 of 1986. For the purpose of accurately defining the paralytic shellfish poison(PSP), the authors carried out mouse bioassay and chemical analysis. The results were summarized as follows: 1. The mean amount of paralytic shellfish toxin was 1,207.8 microgram per 100gm meat, and the mean death time of mouse was 5 minutes 16 second. 2. The properties of the PSP were mainly gonyautoxin group by chemical analysis(TLC, IR, 1H-NMR).

Abstract
PDF
- In order to assess the degree of atmospheric pollution and to contribute the health improvement of residents in Pusan, the authors measured CO, SO2, NO2 and TSP level at 3 places by season and time from July, 1985 to April, 1986. The places were S my n, Sasang and Daeshin-dong, which were known as the commercial, industrial and residental area in Pusan, respectively. The Obtained results were as follows: 1) The average concentration of CO was highest with 2.19+/-0.52(3.5-1.0)ppm at Sasang area, and lowest with 1.32+/-0.55(3.0-0.5)ppm at Daeshin-dong areas. 2) The average concentration of SO2 was highest with 0.092+/-0.073(0.378-0.028)ppm at Sasang, and lowest with 0.041/-0.014(0.083-0.019)ppm at Daeshin-dong. 3) The average concentration of NO2 was highest with 0.069+/-0.012(0.090-0.050)ppm at Somyon, and lowest with 0.043+/-0.010(0.061-0.032)ppm at Daeshin-dong. 4) The average concentration of TSP was highest with 300+/-130(780-130) microgram/m3 at Sasang, and lowest with 160+/-80(390-70) microgram/m3 at Daeshin-dong. 5) The level of CO and TSP were highest in summer at Somyon and Daeshin-dong, and in winter at Sasang, respectively. The level of SO2 and NO2 were highest in winter and spring at all areas. 6) The level of all air pollutants were highest in the afternoon or night than in the morning.
