This study was performed to evaluate the coke oven emissions (COE) and polynuclear aromatic hydrocarbon levels in coke manu- facturing industry, secondary lead smelting industry and glass bottle manufacturing industry.
1. There were no significant difference between the means of personal samples and area samples by the types of industry(p>0.05).
The levels of airborne total particulates of the secondary lead smelting industry was the highest(2.30㎎/㎥), and those of the coke manu- facturing industry and glass bottle manufacturing industry were 1.95 ㎎/㎥ and 1.37 ㎎/㎥.
The concentration of COE was the highest in the glass bottle manufacturing industry(0.79 ㎎/㎥), and in order of 0.19㎎/㎥ in the coke manufacturing industry and 0.05 ㎎/㎥ in the secondary lead smelting industry.
COE/total particulates(％) was highest in the glass bottle manufacturing industry(58.1％) and in order of 10.3％ in the coke manufacturing industry and 3.1％ in secondary lead smelting industry. There were significant differences in the total particle concentration and Coe by the types of industry(p<0.05)
2. The levels of airborne total particulates was the highest at the smelting process of secondary lead smelting industry(2.30±0.72 ㎎/㎥), and the lowest at the smelting process of glass bottle manufacturing industry (0.99±1.22㎎/㎥)
Concentration of COE was the highest at the casting process of glass bottle manufacturing industry (1.09±1.15㎎/㎥), the lowest at the smelting process of secondary lead smelting industry(0.06±0,03 ㎎/㎥).
The COE/total particulates(％) was the highest at the casting process of glass bottle manufacturing industry(65.9±20.5％), and the lowest at the smelting process of secondary lead smelting industry(3.1±2.7％).
3. There were positive correlations between level of The airborne total particulates and concentration of COE in COKE manufacturing industry and glass bottle manufacturing industry(p<0.05), but negative correlation in secondary lead smelting industry.
4. The numbers of case and rates that over the Threshold Limit Values(TLVs) were 24 (77.4％)cases in glass bottle manufacture, 14(23.7％) cases in the coke manufacturing industry and no one case in secondary lead smelting industry. Total numbers of case and rates that over TLVs were 38(35.5％) cases.
5. The limit of detection(LOD) for PAH was 10 ㎍/㎖) in standard sample. All PAH levels of the cokes manufacturing industry and the secondary lead smelting industry and the glass bottle manufacturing industry were trace or not to detect.
