摘　　要：研究了3阶段预浓缩气相色谱-质谱法检测有机玻璃在雕刻过程中排放的有害气体的组成。研究结果表明,气体中含有12种以上的有机污染物。其中甲基丙烯酸甲酯、丙烯酸甲酯、苯、甲苯、苯乙烯等5种有毒有害物可以作为代表该行业特征的污染物加以监控。The deleterious ingredients in gas emission of sculpturing organic glass were studied, using gas chromatography-mass spectrometry coupled with 3-step preconcentrator. The result showed that more than 12 organic contaminants were contained in gas emission. Methyl methacrylate, benzene, methyl acrylate, styrene and toluene - These major deleterious contaminants would be monitored and controlled as some characteristic compounds in sculpturing organic glass
