摘　　要：劳动卫生学调查表明了，甲厂（生产乙苯车间）各作业点空气乙苯浓度为０．０５～１６．６ｍｇ／ｍ＾３，乙厂（使用车间）为０．０５～２３ｍｇ／ｍ＾３。从甲厂临床体检及化验表明，工人的临床表现，血尿常规检查及肝功能与对照组比较未发现明显改变，然而接触组工人（平均工龄１２．６年）尺神经感觉神经传导速度和右眼模式翻转视觉诱发电位Ｎ２波潜伏期比对照组显著延长。根据所获结果，结合文献报道和毒理学资料。Industrial survey indicated that the concentration of ethylbenzene in the air of worksites in A and B plants was 0.05-16.6mg/m￣3 and<0.08-23 mg/m￣3 respectively,The results of medical and laboratory examination showed that there is no significant changes in clinical manifestation, liver function and routing tests of blood and urine in exposed workers,compared with the references.However,the latency N_2 of pattern reversal visual voked potential and sensory nerve conduction velocity was significantly slower in exposed workers than those of the controls,The MAC recom mended was 50mg/m￣3.
