Toxic chlorinated hydrocarbons (polychlorinated biphenyls, benzenes and dioxins and furans) and polyaromatic hydrocarbons were examined in combustion gas and deposited soot wipe samples from simulated house fires. Concentrations of these substances were high during the fires, the amounts of polychlorinated dioxins and furans (PCDD/Fs) in the combustion gas varying from 1.0 to >7.2 ng/m3 (I-TEQ) and those of polyaromatic hydrocarbons from 6.4 to 470 mg/m3. Thus large amounts of organic compounds may be released in house fires. As a result, there is a need for careful personal protection of fire-fighters and remediation workers against combustion gases during a fire and on contaminated surfaces after it.
对模拟房屋火灾产生的燃烧气体和沉积的烟尘擦拭样本中的有毒氯代烃(多氯联苯、苯以及二噁英和呋喃)和多环芳烃进行了检测。火灾期间这些物质的浓度很高,燃烧气体中多氯二噁英和呋喃(PCDD/Fs)的含量在1.0至>7.2纳克/立方米(以毒性当量计)之间变化,多环芳烃的含量在6.4至470毫克/立方米之间。因此,房屋火灾中可能会释放大量有机化合物。所以,有必要在火灾期间以及火灾后对受污染表面,为消防员和清理人员提供针对燃烧气体的仔细的个人防护。
