A notable discard automobiles recycling plant located in southern Taiwan was selected for the preliminary study. At the operation area of the automobiles recycling plant, according to the operation procedures and work features, the interior of the plant was divided to 8 sampling sections: (1) office section (2) details dismantlement section (3) discard engine storage section (4) waste oil storage section (5) environmental protection dismantlement section (6) the outer road of the plant (7) discard automobiles storage section (8) current discard automobiles storage section. As conducted the sampling, the air bag method of the standard investigation was used for the air collection. At each sampling section, according to the height of squat position of the work staff (~ 90 cm) and the height of stand position of the work staff (~ 150 cm) conducted every each (3) three sampling air bags collection (total 48 air bags). The air samples of VOCs were analyzed by Gas Chromatography-Mass Spectrophotometer (GC/MS). This investigation reveals that the characteristics of VOCs emitted from the operation area, the concentration of VOCs is higher in the environmental protection dismantlement section (Styrene, concentration 669.17μg/m3) and waste oil storage section (P-Xylene, concentration 1663.01μg/m3). The highest concentration of VOCs of the chemical compound is benzene, alkane is the less, alkene is the least. The higher concentration of VOCs in the environmental protection dismantlement section and waste oil storage section is worthy to study and investigate if the VOCs emitted would affect the health of the work staff of the recycling plant.
