Objectives: For the purpose of preparing the fundamental data and control the working environment and assessing the status of working environmental in manufacturing industry of bodies for motor car and of parts. Methods and Materials: Accessories for motor car and its engines the auther measured the noise level, concentration of dust, heavymetals, organic solvents, chemicals to 99 industries(24 working processes) form Feb. 2000 to Oec. 2000. Results: The results were as follows : 1. Mean noise level cutting, grinding, pressing, foundries and shot-blast was exceeded to threshold limit value(TLV) of noise. 2. Mean concentration of total dust was not exceeded to TLV. 3. Mean concentration of Mn in welding process and Pb in drying, welding, fabricating, rolling was exceeded to TLV. 4. Mean concentration for chemicals and organic solvents were not exceeded to TLV. 5. Mean concentration of dust and heavymetals were statistical significant difference between with local ventilation system and without local ventilation system. Conclusion: Above results, author suggest to prepare more passively control to working environment where exceeded the TLV.
