有机卤系阻燃剂火灾烟气的毒性影响评价

Toxicity study of gases released during heating from organ halogen flame-retardants

对有机卤系阻燃剂燃烧产物的毒性影响进行了分类,研究了人体毒性、生态毒性、光化学烟雾等6类毒性影响指标,并给出了各个影响类别潜值的计算方法。在各类单项影响指标的基础上,提出了毒性影响指数化方程,可简单全面地评价有机卤系阻燃剂燃烧产物的综合毒性影响。

The study of flame retardant materials is becoming the one of hot researches in fire theories at present. Of course, the eye of all worlds is also focused on its environmental safety and its toxicity of gases released during heating more and more. In this paper, the toxicity impact types of organ halogen flame-retardants are classified. And eight types are studied,such as human toxicity, ecological toxicity and photochemical smog, and then the impact potential is given also. The exponential equations are put forward on the basis of the toxicity impact types, which can be used to assess simply but comprehensively the synthetic toxicity impact of gases released during heating from organ halogen {lame-retardants.
