摘要
随着社会经济的发展,化工类火灾事故高发多发,对于周边环境和救援人员造成了巨大影响。本工作测定6类化工企业火灾现场土壤和废水中18种多环芳烃含量,样品回收率为95.2%~103.7%。所有土壤和废水样品中均检测出了多环芳烃类化合物,其中泡沫厂、地毯厂的火灾现场样品中的多环芳烃含量较高,苯并[a]蒽等重点致癌物含量约为10μg/g。玻璃胶厂、地毯厂、橡胶厂火灾现场土壤和水样品苯并[a]芘含量超过第二类用地筛选值。地胶厂火灾现场土壤二苯并[a,h]蒽第二类用地筛选值。本工作研究发现化工类火灾现场的土壤和废水样品具有较大环境风险。
The contents of 18 kinds of polycyclic aromatic hydrocarbons(PAHs)in soil and fire wastewater of 6 fire scene were determined.The recovery rate of the samples was 95.2%—103.7%.PAHs were detected in all soil and wastewater samples.The contents of PAHs in samples of foam factories and carpet factories was higher.The content of key carcinogens such as Benzo[a]anthracene was about 10μg/g.The content of benzo[a]pyrene in soil and wastewater samples of fire scene of glass glue factory,carpet factory and rubber factory exceeded the screening value of type II land.The screening values of dibenz[a,h]anthracene in the soil of the fire scene of the ground rubber factory were determined.It was found that the soil and wastewater samples from chemical fire scene had high environmental risk.
