介绍了对弹性聚氨酯泡沫燃烧产物毒性的相关研究,并对其是否能用于毒性危害分析进行了评估。研究显示,暴露到聚氨酯燃烧产物中的人会导致中毒。窒息气体氮气有效剂量法能有效预测受害人因暴露于聚氨酯燃烧产物而导致的行为能力丧失情况。同时,也证明有效剂量法不能正确预测聚氨酯阴燃时情况。该方法不适用于热分解。研究发现,目前很多经验方法具有很大的局限性,对毒性危害研究造成了很多负面的影响。烟气粒子携带毒物的吸入和传播以及化学合成复杂的毒物,研究和考虑得很少。因此,很有必要对复杂毒性有机体的火灾燃烧产物进行更深入的物理和化学分析研究以及动物模型研究。
The related studies on the toxicity of flexible polyurethane foam combustion products were introduced and their suitability for toxicological hazard analysis was evaluated. Research shows that people exposed to polyurethane combustion products can cause poisoning. Asphyxia Gas The Nitrogen Effective Dose Method effectively predicts the loss of ability of the victim to experience exposure to polyurethane combustion products. At the same time, also proved that the effective dose method can not correctly predict when the polyurethane smoldering. This method is not suitable for thermal decomposition. The study found that many of the current empirical methods have great limitations and have had a lot of negative impact on toxicological hazard studies. Flue gas particles carrying toxicant inhalation and transmission as well as the chemical synthesis of complex poisons, research and consideration very little. Therefore, it is necessary to carry out more in-depth physical and chemical analysis studies and animal model studies on fire-combustion products of complex toxic organisms.
