摘　　要：目的了解绵阳市新装修住房空气中甲苯二异氰酸酯（TDI）污染水平。方法了解住房装修的基本情况,测定空气中游离甲苯二异氰酸酯的含量,对结果进行卫生学分析与评价。结果空气中游离TDI含量较高的地方,主要是TDI的使用场所,其次是聚氨酯油漆喷涂和烘烤现场,含量可达0.10 mg/m^3-1.40 mg/m^3。居室装修时间在4个月以内,装修完后1个月-6个月,空气中甲苯二异氰酸酯测定值≤0.036 mg/m3的样品可达到85.5%。居室装修后空气中残留的TDI主要以2,4-甲苯二异氰酸酯为主。结论住房装修存在甲苯二异氰酸酯污染室内空气的问题,必须引起作业工人和居住者的高度重视。住房装修后,要进行空气中游离TDI含量的检测,达到卫生标准后方可入住。Objective To investigate the toluene diisocyanate（ TDI） pollution status in the air from the newly decorated houses in Mianyang. Methods To investigate the basic information of housing decoration,and determine the toluene diisocyanate levels in the air,and finally analyze and evaluate the determination results. Results In the air of sites using TDI,the TDI levels were higher,followed by the sites of polyurethane paint spraying and baking,whose levels were up to 0. 10 mg / m^3- 1. 40 mg / m^3.For the air of unused houses for 1- 6 months after decoration within 4 months,the contents of the toluene diisocyanate in85. 5% air samples were ≤0. 036 mg / m3. The TDI detected in the air of decorated rooms were mainly 2,4- toluene diisocyanate. Conclusion There is the problem of toluene diisocyanate pollution in indoor air of the newly decorated houses,so it should be paid great attention to the workers and residents. After decoration,the content of TDI in the air should be detected and the national hygienic standards should be met before occupancy.
