Abstract

|
|
This study was performed to evaluate the threshold limit values(TLVs) exceeding rates and periodical changes based on the results from work environmental measurement for 40 factories applied health service program, located in Cheonnan area, from 1995 to 1997.
The obtained results were as follows;
1. The hazaed frequency in environmental monitoring were noise(865, 34.4%), illumination(804, 31.9%), dust(205, 8.1%), organic solvent(371, 14.7%), lead(114, 4.5%), and specific chemicals(31, 1.2%), heavy metal(127, 5.0%) in order.
2. The order of TLVs exceeding rate of hazardous agents by type of industries were cement-related manufacture(42.3%), fiber industry(40.0%), food stuff industry(24.3%), metal work industry(21.8%), electronics manufacture (9.9%), other industries(10.2%), chemical industry(7.9%).
3. The mean exceeding rates of hazard by type of industry were 29.5% in noise, 27.3% in dust, 25.8% in specific chemicals, 10.2% in solvent and 7.9% in lead, but none in heavy metal.
4. The average of standardized values of noise divided by TLV were decreased in food stuff industries and chemical industries, but not changed in fiber and cement-related industries. While, the average of standardized values of organic solvents divided by TLVs were decreased in electronic manufacturing industries and other industries.
