摘要
目的了解苏州工业园区近几年车间空气中苯、甲苯、二甲苯(三苯)污染程度及整治效果。方法依据国标方法进行采样、检测、分析,对该项目职业病危害控制效果进行评价。结果 "三苯"超标率逐年下降,高毒性苯检出率逐年下降。结论近几年防控措施较为有效,加强对超标企业的监测,减少高毒性苯的使用,降低超标率将是今后职业卫生工作的重点。
[Objective]To understand the contamination degrees of benzene,toluene and xylene in workplace air and the rectifying effect in Suzhou Industrial Park.[Methods]The sampling,testing and analysis were on the basis of national standard method,the control effect of occupational hazards in this project is evaluated.[Results]The over standard rates of benzene,toluene and xylene decreased annually,the detection rate of highly toxic benzene decreased annually too.[Conclusion]In recent years,the efficient prevention and control measures have been adopt.The key to occupational health work in future are strengthening the monitoring of over standard enterprise,decreasing the use of high toxic benzene,reducing over standard rate.
