许多研究表明苯乙烯是一种神经毒物,而对苯乙烯影响视觉功能的报道并不多见。为探讨苯乙烯对人体色觉的损害状况,作者进行了这次研究。接触组为60例年龄20～56岁(平均29.5岁)的某造船厂男性工人,他们在用玻璃增强聚酯物质时接触苯乙烯,接触工龄1～29年(平均6.5年)。工人在工作时戴手套,但不戴口罩。依据接触时间将受试者分为4组:第1组14人,接触时间<1年:第2组18人,接触时间1～5年,第3组14人,接触时间6～10年;第4组14人,接触时间>10年。在车间中安置16个采气装置,用气—质联机法检测到车间空气中苯乙烯平均浓度为112.8mg/m~3,偶尔
Many studies show that styrene is a neurotoxic agent, and the reports that styrene affects visual function are rare. To investigate the damage of human body color vision caused by styrene, the authors conducted this study. The contact group consisted of 60 male workers at a shipyard aged 20-56 years (average 29.5 years) who were exposed to styrene with glass-reinforced polyester materials and were exposed to 1- 29 years of service (mean 6.5 years). Workers wear gloves at work, but do not wear masks. According to the contact time, the subjects were divided into 4 groups: group 1, 14 people, contact time <1 year: group 2, 18 people, contact time 1 to 5 years, group 3, 14 people, contact time 6 to 10 years; Group 4 14 people, contact time> 10 years. Sixteen gas gathering devices were placed in the workshop, and the average concentration of styrene in the air of the workshop was 112.8mg / m ~ 3 detected by gas-mass online method. Occasionally,
