AbstractAbstract 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).

AbstractAbstract 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.

AbstractAbstract PDF
This study was conducted in order to investigate the status of harmful working environment on twelve rubber and ten chemical products manufacturing industries in Busan area over a period of five months from June 1 to October 31, 1980. The summarized results were as follows; 1. The highest and lowest mean values of harmful environmental elements in workroom of rubber products manufacturing industries were noted in twisting (98.7dB) and coating department (77.3dB) to noise, molding (6.43mg/m3) and forming (1.33mg/m3) to dust, bonding (toluene 463.7ppm, xylene 83.3ppm and benzene 6.7ppm, respectively) to organic solvents respectively. Also in chemical products manufacturing, they were noted in grinding (95.1dB) and shining department (76.8dB) to noise, packing (4.30mg/m3) and staining (3.20mg/m3) to dust, shining (393.3ppm and 375.0ppm, respectively) and varnishing(125.5ppm and 121.7ppm, respectively) to toluene and xylene, and scattering (51.8ppm) and mixing (23.9ppm) to benzene, respectively. 2. The mean values of harmful elements in workroom of rubber products manufacturing were 86.3dB to noise, 4.16mg/m3 to dust, 258.2ppm to toluene, 230.3ppm to xylene, and 54.0ppm to benzene, respectively. Also in chemical products manufacturing, they were 85.2dB to noise, 3.69mg/m3 to dust, 227.9ppm to toluene, 213.2 ppm to xylene, and 36.3ppm to benzene, respectively. 3. Number of workers exposed to harmful working environment, over TLV, of a total 10,195 workers in rubber manufacturing were 1,002(9.8%) to noise, 212(2.1%) to dust, 1,581(15.5%) to tolune, 1,509(14.8%) to xylene, and 1,524(15.0%) to benzene, respectively. Number of workers exposed to harmful working environment, over TLV, of a 1,913 workers in chemical products manufacturing were 112(5.9%) to noise, 132(6.9%) to each organic solvent, respectively. 4. The values of noise and dust of rubber and chemical products manufacturing in 1980 were lower then those in 1977, but the value of organic solvent in 1980 was with that in 1977.
